Series A Cap Table Checklist: What Investors Expect to See

By Toby Morning
# Series A Cap Table Checklist: What Investors Expect to See A Series A cap table checklist covers the ownership structure, legal documentation, and equity hygiene that institutional investors review before writing a check. VCs typically expect a clean cap table with a properly sized option pool, no messy convertible instruments, and clear founder vesting — and they will walk away from deals where the cap table raises red flags. This checklist covers exactly what Series A investors look for, what problems to fix before you start fundraising, and how to present your cap table professionally. ## Why Your Cap Table Matters at Series A At pre-seed and seed, investors are betting on the team and the idea. By Series A, they're evaluating the business — and the cap table is part of that evaluation. A messy cap table signals operational immaturity, potential legal liability, and future governance headaches. Series A due diligence typically takes 4-8 weeks. Cap table issues discovered during diligence can delay or kill a deal. Fix them before you start pitching. ## The Complete Series A Cap Table Checklist ### 1. Founder Equity and Vesting Investors want to see: - **All founders on vesting schedules.** Even if a founder has been working for two years, remaining equity should vest. If a founder leaves pre-Series A with fully vested shares and no buyback right, that's dead equity. - **Standard 4-year vest with 1-year cliff.** Variations are fine (some YC companies use shorter cliffs), but explain any non-standard terms. - **Reasonable founder splits.** A 90/10 split between two equal co-founders raises questions. Investors want splits that reflect actual contributions. - **No departed founders with large stakes.** If a co-founder left, their unvested shares should have been repurchased. Lingering dead equity is a red flag. ### 2. Option Pool Size - **10-20% unallocated option pool** is the standard expectation. Most Series A investors will require a top-up to 15-20% pre-money if the pool is too small. - **Board-approved equity incentive plan (EIP)** must be in place. The plan document defines the total share reserve, exercise terms, and types of awards (ISOs, NSOs, RSUs). - **409A valuation current and defensible.** Your strike price for new option grants must be based on a 409A valuation less than 12 months old. Stale valuations create tax liability for employees. ### 3. Convertible Instruments (SAFEs and Notes) - **All SAFEs and convertible notes documented** with clear conversion terms — valuation cap, discount rate, and any pro rata rights or MFN clauses. - **Conversion modeling done.** Show investors what the cap table looks like post-conversion. SAFEs that convert at different caps create complex waterfall scenarios — model them in advance. - **No unusual terms.** Side letters, super pro rata rights, advisory shares with acceleration clauses — these create friction at Series A. Disclose everything upfront. - **Interest accrual calculated** (for convertible notes). Show the current principal plus accrued interest to avoid surprises during conversion. ### 4. Share Class Structure - **Authorized shares properly set.** Your certificate of incorporation should authorize enough shares for the current cap table plus the Series A round and option pool top-up. - **Common stock clearly defined.** One class of common stock with standard voting rights (1 share = 1 vote) unless there's a specific reason for dual-class structure. - **Par value set.** Typically $0.00001 or $0.0001 per share for Delaware C-corps. ### 5. Legal Documentation Investors (or their lawyers) will request: | Document | Why It Matters | |----------|---------------| | Certificate of Incorporation (restated) | Confirms authorized shares, par value, share classes | | Board resolutions for all equity issuances | Proves grants were properly authorized | | 83(b) election filings | Confirms founders/early employees filed on time | | Stock purchase agreements | Documents share issuances to founders and early stakeholders | | Option grant notices and agreements | Individual grant terms for each option holder | | SAFE/convertible note agreements | Full terms for all convertible instruments | | Equity incentive plan (EIP) | Approved option pool with board resolution | | 409A valuation report | Current fair market value for option strike prices | | IP assignment agreements | Confirms all IP is owned by the company, not individuals | ### 6. Cap Table Hygiene - **Single source of truth.** Your cap table should live in one system — not split across spreadsheets, email threads, and legal docs. - **Fully diluted share count.** Present your cap table on a fully diluted basis — including all outstanding options, warrants, and convertible instruments. - **No fractional shares.** Clean up any rounding issues from previous calculations. - **Exercise history tracked.** For any options that have been exercised, track the exercise date, shares purchased, and payment received. ### 7. Investor-Ready Presentation When you share your cap table with a Series A investor, include: - **Summary view:** ownership percentages on a fully diluted basis, broken down by stakeholder category (founders, employees, advisors, investors). - **SAFE/note conversion scenarios:** what the cap table looks like at the proposed Series A valuation after all instruments convert. - **Option pool analysis:** granted vs. unallocated options, vesting schedule summary, and any upcoming cliff dates. - **Dilution waterfall:** how ownership changes from current state through Series A close. ## Common Cap Table Problems That Kill Series A Deals ### Dead Equity A departed co-founder holds 25% of the company with no vesting and no buyback mechanism. The investor now knows that 25% of their investment is going to someone who isn't working on the company. **Fix:** Implement vesting from day one. If a founder has already left, negotiate a share repurchase before fundraising. ### Missing 83(b) Elections Early employees received restricted stock but didn't file 83(b) elections within the 30-day window. They now face ordinary income tax on the spread between their purchase price and the current FMV as shares vest. **Fix:** This can't be retroactively fixed. Disclose it to investors and ensure all future grants have proper 83(b) filing procedures. ### Excessive SAFE Dilution The company raised $2M across six SAFEs at different valuation caps. When these all convert at Series A, the founders discover they own less than 40% of the company before the Series A investor takes their share. **Fix:** Model your fully diluted cap table including all SAFE conversions before each new raise. ### Unauthorized Equity Grants Stock options were granted to employees without proper board approval or a 409A valuation. These grants may be invalid or create significant tax liability. **Fix:** Get retroactive board approval where possible. Obtain a new 409A valuation and re-price any grants that were issued below FMV. ## How OpenCap Stack Helps OpenCap Stack gives you a single, auditable cap table that's always investor-ready: - **Automatic dilution modeling** — see the impact of any financing round before it happens - **SAFE conversion tracking** — model all your convertible instruments converting at different valuations - **409A integration** — keep your valuation current and your strike prices defensible - **One-click exports** — generate the investor-ready summary, waterfall analysis, and fully diluted cap table that VCs expect - **MCP integration** — manage your cap table through AI agents in Claude Code or Cursor Start for free at [opencapstack.com/register](https://opencapstack.com/register). ## FAQ ### What should a clean cap table look like before Series A? A clean Series A cap table shows all founders on vesting schedules, a 15-20% unallocated option pool, all SAFEs and convertible notes documented with clear conversion terms, a current 409A valuation, and a single source of truth for ownership data. ### How big should my option pool be for Series A? Most Series A investors expect a 15-20% unallocated option pool on a pre-money basis. If your current pool is smaller, the investor will typically require a top-up before the round closes, which dilutes existing shareholders. ### What happens to SAFEs when I raise a Series A? SAFEs convert to preferred stock at the Series A. Each SAFE converts based on its specific terms — valuation cap, discount, or MFN clause. SAFEs with lower caps convert to more shares. Model all conversions together to see the combined dilution impact. ### How far in advance should I clean up my cap table before fundraising? Start at least 3-6 months before you plan to raise. Some fixes — like repurchasing a departed founder's shares or obtaining a new 409A valuation — take weeks to complete. ### Can I use a spreadsheet for my Series A cap table? You can, but investors will be skeptical. Spreadsheets have no audit trail, are prone to formula errors, and can't model complex SAFE conversion scenarios reliably. Cap table software provides the accuracy and professionalism that institutional investors expect. ### What is the most common cap table mistake founders make before Series A? Not modeling SAFE conversion dilution. Founders often raise multiple SAFEs without understanding the cumulative impact. When all SAFEs convert at Series A, founders are surprised to find their ownership much lower than expected.
