Cap table in 2026: from 100% to 23% in 3 rounds

You own 100% of your company. After a seed round, you own 80%. After Series A, 55%. After Series B, 38%. That’s not a problem — unless you don’t see it coming.

23%

Most first-time founders don’t look at their cap table until a term sheet is on the table. By then, the math is already locked in. The founders who negotiate well are the ones who ran the numbers six months before the round.

What a cap table actually is

A cap table is a spreadsheet that shows who owns what. Every row is a shareholder — founders, investors, employees with stock options. Every column is a round. The numbers change after every financing event, and they only go in one direction for founders: down. That’s dilution. It’s not inherently bad. Owning 38% of a $50M company is better than owning 100% of a $200K company. But you need to understand the math before you sign anything.

The dilution walkthrough

Here’s how a typical cap table evolves. These are simplified numbers to illustrate the mechanics.

Founding: 100% Two co-founders split 100% of shares. Let’s say 10,000,000 shares at $0.001 each. Company valuation: $10,000. This is your starting point.

Seed round: founders go from 100% to 75% You raise $500K on a $2M pre-money valuation. The investor gets $500K / ($2M + $500K) = 20% of the company. You also set aside a 5% employee stock option pool. Founders now hold 75%. Carta’s Q1 2024 data shows median seed dilution at 20.1% [1] — closely matching this scenario.

Series A: founders go from 75% to 52.5% You raise $3M on a $12M pre-money valuation. New investor gets $3M / ($12M + $3M) = 20%. The option pool gets topped up to 10% (adding another 5%). Everyone’s existing stake dilutes proportionally. Your 75% becomes roughly 52.5%. Median Series A dilution: 20.5% [1].

After three events, founders went from 100% to 52.5%. Two dilution rounds and one option pool expansion. Every single one was necessary. The question isn’t whether to dilute — it’s whether you diluted at the right valuation.

Carta’s data from tens of thousands of cap tables confirms this pattern: median founder ownership is 56.2% after seed, 36.1% after Series A, and 23% after Series B [2]. Your mileage will vary with valuation, round size, and how many co-founders you have — but the trajectory is consistent.

SAFEs and the modern seed round

If you’re raising a pre-seed or seed round today, you’re almost certainly using a SAFE (Simple Agreement for Future Equity) — not a priced round. Carta data shows 92% of pre-seed rounds use SAFEs [3].

Here’s the problem: SAFEs don’t appear on your cap table until they convert into equity, typically at your next priced round. This creates what experienced founders call phantom dilution — you think you own more of the company than you actually do, because the SAFE holders aren’t yet reflected in the ownership breakdown.

The standard discount on a SAFE is 20%, used in 63% of cases [3]. That discount means SAFE holders convert at a lower price per share than Series A investors, giving them more shares for the same dollar invested.

Run the math on a concrete example. You raise $1M on a SAFE with an $8M valuation cap. When your Series A prices the round, that SAFE converts at the $8M cap. The SAFE holders get $1M / ($8M + $1M) = 11.1% of the company. That 11.1% didn’t show up on your cap table during the months (or years) between the SAFE closing and the Series A. But it was always there, waiting.

Nearly 10% of startups sold over 30% of their company in a single round [1] — often because stacked SAFEs converted simultaneously and the dilution hit harder than expected. Track your SAFEs in a shadow cap table. Model the conversion scenarios before raising more.

The anti-dilution trap nobody explains

What to actually do

Use a spreadsheet. Google Sheets or Excel. Three tabs: current cap table, next round model, exit scenarios. Don’t pay for cap table software until you’ve raised a Series A and have employees exercising options. Until then, Carta is overkill.

Watch the option pool shuffle. Investors often require a 10-15% option pool — created before their money goes in, meaning dilution falls entirely on founders. This is standard, but it’s also negotiable. The difference between a 10% and 15% pool pre-money can cost you 3-5% of your company.

Understand every term in the venture capital agreement. Participation rights, anti-dilution clauses, pro-rata rights — they all affect your cap table in ways that don’t show up in the ownership percentage.

Factor product costs into your dilution model. If you’re raising $2M and allocating $800K to product development, that’s 40% of your raise going to software. The real cost of building software in 2026 directly determines how long your runway lasts — and how much you need to raise. Founders who build lean with a bootstrapping mindset even while raising VC often end up with better cap table math because they stretch every dollar further. We see this with founders who use their pitch deck’s technical slide to show investors they’ve already built efficiently.

Why we see cap tables

We’re not accountants or lawyers. We’re a software agency. But we work with founders from pre-seed through Series B, and the cap table directly affects our engagement. How much of a $500K seed round goes to product development? How does the build timeline align with the next raise? What features need to ship before the Series A data room opens?

We help founders plan software budgets around their raise — so the product roadmap and the cap table tell the same story.
