Cap Table Management Guide: Everything VC-Backed Companies Need to Know
409A valuations, SAFE note conversions, equity round dilution, option pool mechanics — and the cap table mistakes that kill deals during due diligence.
Your cap table tracks who owns what in your company, and 73% of startups have errors in it before Series A. This guide covers 409A valuations, SAFE note conversions, equity round dilution mechanics, and option pool management—plus the common mistakes (missing 83(b) elections, undocumented equity, untracked SAFEs) that kill deals during due diligence.
Your cap table is the single most important financial document in your company. Not your P&L. Not your projections. Your cap table — because it defines who owns what, who controls what, and who gets paid when the exit happens.
And yet, I routinely see companies raising Series A rounds with cap tables that are missing entries, have undocumented equity promises, or carry SAFEs that nobody has modeled for conversion. The term sheet comes in. The lawyers start diligence. And suddenly everyone discovers that the ownership math doesn't add up.
This guide covers everything: what belongs on your cap table, how equity rounds change it, how SAFEs and convertible notes convert, why 409A valuations matter, and the specific mistakes that kill deals. I'm writing this for founders, early-stage finance leads, and anyone who needs to understand startup equity mechanics from the ground up.
1. What Is a Cap Table and Why It Matters
A capitalization table — cap table — is the ledger that records every ownership stake in your company. Every share of common stock, every preferred share, every option grant, every warrant, every SAFE, every convertible note. It answers one question: who owns what?
But it's more than a spreadsheet. Your cap table represents three things that matter to everyone from your co-founder to your Series B lead investor:
- Ownership — Who holds what percentage of the company, on both an issued and fully diluted basis
- Dilution — How each new share issuance reduces existing shareholders' percentage ownership
- Control — Voting rights, protective provisions, board seats, and who can block or approve major decisions
Who Scrutinizes Your Cap Table
Investors check the cap table before writing a term sheet. They want to know how much of the company they're buying, what the fully diluted share count looks like, whether the founders have enough equity to stay motivated, and whether the capital structure is clean enough to close a deal without legal drama.
Acquirers use the cap table to structure purchase price allocation. In an M&A transaction, the cap table determines who gets paid, in what order (liquidation preferences), and how much. Errors on the cap table directly translate to errors in the purchase price waterfall.
Lenders evaluate the cap table to understand ownership concentration, guarantee structures, and whether the equity cushion supports the debt they're underwriting.
2. Cap Table Components
Every cap table tracks the same core instruments. Here's what each one means and how it works:
Common Stock
The baseline equity instrument. Founders, early employees, and advisors typically hold common stock. It carries voting rights (usually one vote per share) but sits at the bottom of the liquidation waterfall — meaning in an exit, common shareholders get paid last, after all preferred shareholders and debt holders.
Preferred Stock
What investors get in priced rounds (Seed, Series A, Series B, etc.). Preferred stock comes with special rights: liquidation preferences (1x is standard, meaning they get their money back before common shareholders get anything), anti-dilution protection, pro-rata rights, and often board seats or observer rights.
Stock Options (ISOs vs. NSOs)
Incentive Stock Options (ISOs) receive favorable tax treatment — no ordinary income tax at exercise if you meet the holding period requirements (1 year from exercise, 2 years from grant). Available only to employees. Non-Qualified Stock Options (NSOs) are taxed as ordinary income at exercise on the spread between strike price and fair market value. Available to employees, contractors, and advisors.
Warrants
Similar to options but typically issued to investors, lenders, or strategic partners. Warrants give the holder the right to purchase shares at a fixed price within a specified time frame. Common in venture debt deals.
SAFEs (Simple Agreement for Future Equity)
Created by Y Combinator. A SAFE isn't equity — it's a contractual right to receive equity in a future priced round. SAFEs don't appear as shares on the cap table until they convert, but they absolutely must be tracked because they represent future dilution.
Convertible Notes
Debt instruments that convert to equity at a future priced round. Unlike SAFEs, convertible notes accrue interest and have a maturity date. The conversion mechanics are similar to SAFEs: valuation cap, discount rate, or both.
Sample Cap Table — Post-Seed Stage
| Shareholder | Instrument | Shares | % Issued | % Fully Diluted |
|---|---|---|---|---|
| Founder A | Common | 4,500,000 | 45.0% | 36.0% |
| Founder B | Common | 3,500,000 | 35.0% | 28.0% |
| Seed Investor (SAFE) | SAFE → Preferred | 1,250,000 | 12.5% | 10.0% |
| Angel Investor | SAFE → Preferred | 500,000 | 5.0% | 4.0% |
| Advisor 1 | Common (vesting) | 250,000 | 2.5% | 2.0% |
| ESOP (unallocated) | Option Pool | — | — | 15.0% |
| Employee Options (granted) | ISOs/NSOs | 625,000 | — | 5.0% |
| Total | 10,625,000 | 100% | 100% |
3. Building a Clean Cap Table from Day One
The decisions you make at incorporation echo through every future fundraise, option grant, and exit. Get these right from the start.
Founder Splits
Equal splits (50/50 or 33/33/33) are the default — and they're not always wrong. But they should be a deliberate choice, not a default because the conversation feels awkward. Consider contribution differences: who's full-time vs. part-time? Who brought the IP? Who's funding the first six months? Document the rationale in writing.
Vesting Schedules
The standard is 4-year vesting with a 1-year cliff. After the cliff, 25% of shares vest. The remaining 75% vest monthly over the next 36 months. This protects everyone: if a co-founder leaves after three months, they don't walk away with 25% of the company for a quarter's work.
Year 1 cliff: 25% vests · Months 13–48: ~2.08%/month · Total: 100% at 48 months
Reverse vesting for founders: Even if founders already own their shares, it's common (and investors will require it) for founders to have reverse vesting — meaning the company has a repurchase right on unvested shares if the founder leaves. This is different from an option vesting schedule, but the economic effect is similar.
The 83(b) Election — The Mistake Founders Make
When you receive restricted stock subject to vesting, the IRS gives you a choice: pay tax on the stock's value now, or pay tax as it vests. If you file an 83(b) election within 30 days of receiving the stock, you pay tax on the current value — which at incorporation is typically fractions of a penny per share. Total tax bill: often less than $10.
The critical rule: You must file the 83(b) election with the IRS within 30 days of receiving the stock grant. There are no extensions. There is no late filing. Miss it, and there is no fix.
4. SAFE Notes & Convertible Notes on the Cap Table
SAFEs and convertible notes are the most common instruments for pre-Seed and Seed fundraising. They're simple to execute, but their impact on your cap table is anything but simple.
Pre-Money vs. Post-Money SAFEs
Pre-money SAFEs (the original YC version) calculate conversion price based on the pre-money valuation of the next priced round, divided by the existing share count. Multiple pre-money SAFEs dilute the new investor, not each other — which means the more SAFEs you issue, the less dilution each SAFE holder experiences (and the more dilution the priced round investor absorbs).
Post-money SAFEs (current YC standard since 2018) define the SAFE holder's ownership as a percentage of the post-money cap table including the SAFE itself. This makes dilution transparent and predictable. If you raise $500K on a $5M post-money cap, the SAFE holder will own 10% — period. The dilution comes from the founders and existing shareholders.
Valuation Caps and Discount Rates
A valuation cap sets the maximum valuation at which the SAFE converts. If the next round is priced at $20M pre-money but the SAFE has a $10M cap, the SAFE converts at the $10M valuation — giving the SAFE holder twice as many shares as they'd get at the round price.
A discount rate (typically 15-25%) gives the SAFE holder a discount on the next round's price per share. The investor gets whichever mechanism produces more shares — cap or discount.
SAFE Conversion Example
Let's walk through a concrete example. Company has 8,000,000 shares outstanding. A SAFE investor invested $500,000 at a $5M post-money valuation cap.
SAFE Ownership = $500K ÷ $5M cap = 10% · Conversion Shares = 10% ÷ 90% × 8M = 888,889 shares
| Scenario | SAFE Investment | Val Cap | Series A Pre-$ | Converts At | Shares Received | % Ownership |
|---|---|---|---|---|---|---|
| Cap applies | $500K | $5M | $15M | $5M cap | 888,889 | 10.0% |
| Discount applies | $500K | None | $15M | 20% discount | 333,333 | 4.0% |
| Cap + Discount | $500K | $5M | $15M | Better of both | 888,889 | 10.0% |
| Flat round (cap doesn't help) | $500K | $5M | $4M | Round price | 1,000,000 | 11.1% |
Convertible Notes vs. SAFEs
Convertible notes add two complications: accrued interest and a maturity date. A $500K note at 5% annual interest accrues $25K per year. At conversion, the investor converts $500K + accrued interest into shares. The maturity date creates a deadline — if no qualifying round happens, the note technically becomes due. This can create uncomfortable conversations.
5. 409A Valuations
A 409A valuation is an independent appraisal of your company's common stock fair market value. It determines the strike price for stock options — and getting it wrong can be catastrophic for your employees.
What It Is
Under IRC Section 409A, stock options must be granted with a strike price at or above fair market value (FMV) on the date of grant. A 409A valuation establishes that FMV through methods like discounted cash flow analysis, comparable company analysis, or the backsolve method (working backward from a recent round's preferred stock price to derive the common stock value).
When You Need One
| Trigger Event | Timing | Why It Matters |
|---|---|---|
| Before first option grant | Before granting any options | Sets initial strike price; without it, every option is potentially mispriced |
| Every 12 months | Annual renewal | IRS safe harbor requires a valuation no older than 12 months |
| After a funding round | Within 30–60 days of close | New round price materially changes FMV; old 409A no longer reliable |
| After material events | As soon as practical | Major revenue change, pivot, key hire/departure, M&A discussions |
| Before an exit/IPO | During preparation | Auditors and underwriters will scrutinize the entire 409A history |
What It Costs
A 409A valuation typically costs $2,000–$5,000 for early-stage companies (pre-revenue or early revenue) and $5,000–$10,000+ for later-stage companies with complex capital structures. Providers include Carta (which bundles 409A with their cap table platform), Scalar, Preferred Return, and traditional valuation firms.
The Tax Disaster of Getting It Wrong
- 20% additional federal tax on the value of vested options — on top of ordinary income tax
- Premium interest penalty that accrues from the original vesting date at the underpayment rate + 1%
- State taxes — California, for example, adds its own 20% penalty under Section 409A conformity
For an employee with $200K in vested options, the combined federal and state penalty can exceed $80,000 — plus interest. And the company faces lawsuits from affected employees.
6. Equity Rounds: Seed → Series A → Series B
Every funding round reshapes your cap table. Understanding the mechanics — pre-money vs. post-money, the option pool shuffle, and how SAFEs convert — is the difference between a founder who controls the negotiation and one who gets diluted more than they expected.
Pre-Money vs. Post-Money Valuation
Post-Money Valuation = Pre-Money Valuation + New Investment
If a VC offers a $12M pre-money valuation and invests $3M, the post-money is $15M. The investor owns $3M ÷ $15M = 20%. Simple in theory. In practice, the pre-money number is where every negotiation happens — because it determines how much of the company existing shareholders give up.
Worked Example: Seed Through Series A
Let's trace a company from founding through Series A, showing how the cap table evolves at each stage.
Stage 1: Founding
| Shareholder | Shares | % Ownership |
|---|---|---|
| Founder A | 5,000,000 | 50.0% |
| Founder B | 5,000,000 | 50.0% |
| Total | 10,000,000 | 100% |
Stage 2: Seed Round — $1M invested via post-money SAFEs at a $10M post-money cap
| Shareholder | Shares | % Ownership | Dilution from Seed |
|---|---|---|---|
| Founder A | 5,000,000 | 45.0% | −5.0% |
| Founder B | 5,000,000 | 45.0% | −5.0% |
| Seed Investors (SAFEs) | 1,111,111 | 10.0% | — |
| Total | 11,111,111 | 100% |
Stage 3: Series A — $4M invested at $16M pre-money ($20M post-money). VC requires a 15% option pool created pre-money.
| Shareholder | Shares | % Post-Series A | Dilution from Series A |
|---|---|---|---|
| Founder A | 5,000,000 | 27.5% | −17.5% |
| Founder B | 5,000,000 | 27.5% | −17.5% |
| Seed Investors | 1,111,111 | 6.1% | −3.9% |
| Series A Investor | 3,636,364 | 20.0% | — |
| ESOP (Option Pool) | 2,727,273 | 15.0% | — |
| Existing Employee Options | 727,273 | 4.0% | — |
| Total (Fully Diluted) | 18,202,021 | 100% |
7. The Option Pool (ESOP)
The Employee Stock Option Pool is a reserved block of shares set aside for future employee grants. It's one of the most important and most misunderstood elements of the cap table.
Sizing the Pool
The standard ESOP size pre-Series A is 10–20% of fully diluted shares, with 15% being the most common. The right size depends on your hiring plan for the next 18-24 months:
| Role | Typical Equity Grant | Notes |
|---|---|---|
| VP Engineering | 1.0% – 2.0% | Higher if joining pre-Series A |
| VP Sales / Marketing | 0.5% – 1.5% | Depends on revenue stage |
| Senior Engineer | 0.25% – 0.75% | First 10 engineering hires |
| Product Manager | 0.2% – 0.5% | Varies by seniority |
| Junior / Mid-level Hire | 0.05% – 0.2% | After Series A |
| Advisor | 0.1% – 0.5% | Typically 2-year vest, no cliff |
The Option Pool Shuffle
This is the single most important cap table mechanic that founders don't understand until it's too late.
VCs typically require the option pool to be created (or topped up) before the investment closes — meaning it's included in the pre-money valuation. This is called the option pool shuffle, and it means the dilution from the option pool comes entirely from the founders and existing shareholders, not from the new investor.
"$16M pre-money" with a 15% pool = effective pre-money of $13.6M for founders
When a VC offers a $16M pre-money and requires a 15% option pool, they're really valuing the existing shareholders at $13.6M (85% × $16M). The other $2.4M of "pre-money" is the unissued option pool. This is standard practice — but founders who don't understand it overestimate what the pre-money number means for their ownership.
ISO vs. NSO Tax Treatment
| Feature | ISO (Incentive Stock Option) | NSO (Non-Qualified Stock Option) |
|---|---|---|
| Who can receive | Employees only | Employees, contractors, advisors |
| Tax at exercise | No ordinary income tax (but AMT may apply) | Ordinary income tax on the spread |
| Tax at sale | Long-term capital gains (if holding periods met) | Capital gains on appreciation above exercise price |
| Holding periods | 1 year from exercise + 2 years from grant | None required |
| $100K limit | ISOs vesting above $100K/year in value treated as NSOs | No limit |
| Company deduction | No deduction (if ISO rules met) | Company gets tax deduction at exercise |
Exercise Windows
Standard option agreements give employees 90 days after departure to exercise vested options. If they don't exercise within that window, they forfeit the options. This creates a "golden handcuffs" problem — employees who can't afford the exercise price (plus the tax bill) lose their equity when they leave. Some companies now offer extended exercise windows of 5-10 years. It's more employee-friendly but has tax implications: ISOs convert to NSOs after the 90-day window.
8. Common Cap Table Mistakes That Kill Deals
I've seen each of these mistakes — some of them multiple times — and every one has either delayed a deal, repriced a deal, or killed a deal entirely.
Mistake 1: Missing 83(b) Elections
We covered this above, but it bears repeating: an unfiled 83(b) election is a ticking tax bomb. There's no retroactive fix after 30 days, and it can create six- or seven-figure tax liabilities for founders. Every founder's 83(b) should be filed, acknowledged, and stored in the company's corporate files.
Mistake 2: Expired or Missing 409A Valuations
Granting options without a current 409A valuation means every one of those options could be mispriced. The penalties fall on your employees, and the legal liability falls on you. Get a 409A before your first option grant and renew it every 12 months or after every material event.
Mistake 3: Handshake Equity Deals
"I'll give you 2% of the company" said verbally to an early advisor, contractor, or friend who helped in the early days — with no documentation. When the Series A lawyer asks for a complete list of equity holders, these verbal promises create legal risk. Document every equity agreement, no matter how small, with proper board approval and signed agreements.
Mistake 4: Too Many SAFEs Without Tracking Conversion
I see companies raise $500K here, $200K there, $300K over there — all on SAFEs with different valuation caps and discount rates. Nobody has modeled what happens when these all convert at the next priced round. Founders are shocked when their expected 60% ownership is actually 42% after SAFE conversions and the option pool shuffle.
Mistake 5: Dead Equity from Departed Founders
A co-founder leaves after six months with no vesting agreement in place. They own 30% of the company and have no obligation to work another day. This is "dead equity" — it sits on the cap table, can't be reclaimed, and makes the company less attractive to investors. Always have vesting in place from day one.
Mistake 6: Not Modeling Dilution Scenarios
Before entering any fundraising negotiation, you should have a dilution model that shows: current cap table, post-round cap table at various valuations, and the impact of the option pool shuffle. Founders who negotiate without this model are negotiating blind.
Mistake 7: Authorized vs. Issued Share Mismatch
Your company's certificate of incorporation authorizes a specific number of shares. If you issue more than authorized — or if your cap table shows more shares outstanding than authorized — you have a corporate governance problem that requires a board resolution and potentially a charter amendment with the state. This is a due diligence red flag.
Mistake 8: Inconsistent Records
The cap table says one thing. The board minutes say another. The state filing says something else. Inconsistencies between your cap table, stock ledger, board resolutions, and corporate filings create a mess that takes lawyers (expensive ones) to untangle.
Mistake 9: Ignoring Transfer Restrictions
Most startup shares have transfer restrictions — ROFR (right of first refusal), co-sale rights, lock-up provisions. If a shareholder transfers shares without following the proper procedures, the transfer may be invalid. Track restrictions in your cap table and enforce the process.
Mistake 10: No Single Source of Truth
The founder has one version of the cap table. The lawyer has another. The investor has a third. None of them match. Designate one system — whether it's Carta, Pulley, or a meticulously maintained spreadsheet — as the single source of truth and keep it updated after every transaction.
9. Cap Table Tools & Software
Here's an honest assessment of the major cap table management tools — what works, what doesn't, and when you actually need one.
| Platform | Best For | Annual Cost | Pros | Cons |
|---|---|---|---|---|
| Carta | Series A+ companies | $3K–$8K+ | Industry standard, integrated 409A, investor portal, scenario modeling | Expensive for early stage, complex onboarding, pricing creep |
| Pulley | Seed to Series A | $0–$3K | Clean UI, free tier for small teams, good SAFE modeling, founder-friendly | Less mature feature set, smaller ecosystem |
| AngelList (Roll Up) | Companies with AngelList investors | Varies | Good integration with AngelList fundraising, SPV management | Tied to AngelList ecosystem, limited if you don't use their fundraising tools |
| Shareworks (Morgan Stanley) | Late-stage / pre-IPO | $10K+ | Enterprise-grade, global equity management, compliance | Overkill for startups, complex pricing, long implementation |
| Spreadsheet (Google Sheets / Excel) | Pre-Seed to early Seed | $0 | Free, flexible, no vendor lock-in, full control | No audit trail, formula errors, doesn't scale, no electronic stock issuance |
Late Seed / Pre-Series A: Move to Pulley or Carta before you start issuing options. The 409A integration alone is worth it.
Series A and beyond: You need Carta or equivalent. The investor portal, scenario modeling, and electronic stock issuance become essential — not optional.
10. When to Bring in a CFO
Most founders manage their own cap table until something breaks. Here are the inflection points where financial expertise becomes essential — not optional:
Pre-Fundraise Cleanup
Before you start your next round, your cap table needs to be accurate, complete, and defensible. A fractional CFO audits the cap table against board minutes, state filings, and stock ledger entries. They model dilution scenarios for different term sheet offers. They ensure your 409A is current and your option grants are properly documented.
409A Coordination
Ordering, reviewing, and managing the 409A process requires someone who understands valuation methodology, can interface with the valuation firm, and can explain the results to the board. A CFO manages this process end-to-end and ensures the valuation is defensible.
Board Reporting
Post-Series A, your board expects a cap table summary in every board package. This includes fully diluted ownership, option pool utilization, recent grants, vesting summaries, and dilution projections for the next 12-18 months. A CFO builds and maintains these reports.
Exit Preparation
Whether you're heading toward an acquisition, an IPO, or a secondary sale, the cap table drives the entire waterfall analysis. Who gets paid, in what order, and how much — all determined by the cap table. A CFO models the waterfall under different exit scenarios and identifies issues before the buyer's diligence team finds them.
11. Due Diligence Readiness
When an investor or acquirer runs due diligence, the cap table is one of the first things they examine. Here's exactly what they check — and what you need to have ready:
| Diligence Item | What They Check | Red Flag If Missing |
|---|---|---|
| Fully diluted share count | Total shares including all options, warrants, SAFEs, notes | Indicates cap table isn't maintained or SAFE conversion isn't modeled |
| Authorized vs. issued shares | Certificate of incorporation matches issued share count | More shares issued than authorized = corporate governance failure |
| Option pool details | Pool size, utilization, individual grants, vesting schedules, exercise prices | Missing grant documentation, inconsistent strike prices, expired grants not cancelled |
| SAFE/Note register | Every SAFE and note with investor, amount, date, cap, discount, terms | Untracked SAFEs create surprise dilution at conversion |
| 409A history | Complete history of 409A valuations with dates and values | Gaps in 409A history = options potentially granted below FMV |
| 83(b) elections | Filed elections for all restricted stock recipients | Missing 83(b) = tax time bomb for key personnel |
| Transfer restrictions | ROFR agreements, co-sale rights, lock-up provisions | Unrestricted shares can create surprise secondary sales |
| Board approvals | Board minutes approving every stock issuance and option grant | Missing approvals = potentially invalid issuances |
| State filings | Certificate of incorporation, amendments, and state compliance | Inconsistencies between cap table and state records |
| Waterfall analysis | Liquidation preference stack, participation rights, conversion mechanics | Can't model exit proceeds = can't close the deal |
The goal isn't just to pass diligence — it's to pass it quickly and cleanly. Every day spent resolving cap table issues during diligence is a day the deal isn't closing. And deals that drag lose momentum, get repriced, or die.
Frequently Asked Questions
What is a cap table and why does it matter?
A cap table is the definitive record of ownership in your company — listing every shareholder, share class, option grant, warrant, SAFE, and convertible note. It determines who gets paid in an exit, how much dilution occurs in each round, and who has control through voting rights. Investors, acquirers, and lenders all scrutinize it during due diligence. A clean cap table signals a well-run company; a messy one raises questions about everything else.
When do I need a 409A valuation?
You need a 409A valuation before granting any stock options, then at least every 12 months afterward. You also need a new one after any material event: closing a funding round, a significant revenue change, a business model pivot, or any event that materially affects the company's value. A current 409A provides "safe harbor" protection for the strike prices you set on option grants.
What happens if my 409A is expired and I issue stock options?
If options are granted without a current 409A — or at a strike price below fair market value — IRC Section 409A imposes severe penalties on the option holders: a 20% additional federal tax on vested options plus a premium interest penalty. California adds its own 20% penalty. The company faces potential employee lawsuits, securities law issues, and a due diligence red flag that can delay or kill your next round.
How do SAFE notes convert on a cap table?
SAFEs convert into preferred stock at the next priced equity round. The conversion price is determined by the valuation cap and/or discount rate in the SAFE. With a post-money SAFE, the investor's ownership percentage is fixed at conversion (investment ÷ cap). The key distinction: pre-money SAFEs calculate based on existing shares only, while post-money SAFEs include the SAFE itself in the fully diluted count, making dilution math more predictable.
What percentage should the option pool be before Series A?
The standard is 10-20%, with 15% being most common. VCs typically require the pool to be created before the investment (the "option pool shuffle"), meaning it comes out of founders' ownership. The best approach is to model your actual hiring plan for the next 18-24 months and negotiate a pool size based on data rather than accepting the default VC request.
How does dilution work through funding rounds?
Each time new shares are issued — through fundraising, option grants, or SAFE conversions — every existing shareholder's percentage decreases. Founders typically go from 100% to ~80% after Seed, ~55-65% after Series A, and ~40-50% after Series B. The exact dilution depends on valuation, round size, option pool sizing, and SAFE conversion mechanics. Model dilution scenarios before every round so you negotiate from a position of knowledge.
What cap table mistakes kill deals during due diligence?
The top deal-killers: missing 83(b) elections (no retroactive fix), expired 409A valuations (potential tax liability for all option holders), undocumented equity promises, untracked SAFEs that create surprise dilution, dead equity from departed founders with no vesting, more shares issued than authorized in the charter, and inconsistencies between the cap table and corporate filings. Any one of these can delay, reprice, or kill a transaction.
Can I manage my cap table in a spreadsheet?
Yes — if your capital structure is simple (founders + a few SAFEs + maybe one angel). Spreadsheets work fine at that stage and cost nothing. The problems start when you add an option pool with multiple grants, SAFEs with different terms, and a priced round with conversion mechanics. A single formula error can misstate ownership. Move to dedicated software (Carta, Pulley) before or during your Series A.
What is the 83(b) election and when should I file it?
An 83(b) election tells the IRS you want to pay income tax on restricted stock at the time of grant (when it's worth almost nothing) rather than when it vests (when it could be worth millions). You must file within 30 days of the stock grant — no extensions, no exceptions, no retroactive filing. At incorporation, when shares are worth fractions of a penny, the tax is negligible. The penalty for missing the deadline can be six or seven figures.
How does a fractional CFO help with cap table management?
A fractional CFO coordinates 409A valuations, models dilution scenarios, ensures proper documentation for every equity transaction, manages option grants, builds board-ready cap table reports, and serves as the point person during investor due diligence. They catch problems before they become deal-killers. At $3,000-$8,000/month versus $250K+ for a full-time CFO, it's the right solution from Seed through Series B.
