When you raise money, you sell new shares, and everyone who already owns the company holds a smaller slice afterwards. That is dilution. It sounds alarming, but a smaller percentage of a much larger, better funded company is usually worth far more than a large percentage of a tiny one. What matters is understanding exactly how each round shrinks your stake, so you can plan and negotiate instead of being caught off guard. This lesson walks through the mechanics from seed to Series A to Series B, the ESOP pool trap, and the arithmetic you can do on the back of one napkin.
What actually happens in a round
A priced round in India is usually a preferential allotment of shares to the investor under Section 62(1)(c) of the Companies Act, 2013, approved by a special resolution passed with at least 75% of votes cast. For an unlisted startup, the price per share must be supported by a valuation report from an IBBI-registered valuer. The company issues brand new shares to the investor, so the total share count rises. You keep the same number of shares, but they now represent a smaller share of a bigger pie.
The simple dilution math
Two formulas do most of the work:
- Post-money valuation = pre-money valuation + new investment.
- Investor's stake = new investment divided by post-money.
Every holder from before the round keeps their share count but sees their percentage multiplied by a retention factor equal to pre-money divided by post-money. If a new investor ends up with 20% of the company, each existing holder is multiplied by 0.8, that is, 1 minus 0.20. Chain these factors across rounds and you can project your ownership years ahead. As a rough benchmark, founders tend to part with somewhere around 15% to 25% at seed, a similar band at Series A, and 10% to 20% at Series B, though the exact figure swings with your leverage and market conditions.
The pre-money ESOP pool effect
Startups reserve an Employee Stock Option Pool, usually 10% to 15% at seed or Series A, to hire and retain talent. This pool is created under Section 62(1)(b) and also needs shareholder approval. Here is the trap: investors almost always insist the pool sits inside the pre-money valuation. That means the pool is carved out of the founders' shares before the investor buys in, so founders alone absorb it. If the same pool were created post-money, the new investor would share that dilution with you. So always ask one question before signing the term sheet: is the ESOP pool pre-money or post-money? The answer can quietly cost founders several extra percentage points.
Worked example: two founders, three rounds
Start: the founders together own 100%.
Seed. You raise INR 2 crore at an INR 8 crore pre-money valuation, so post-money is INR 10 crore and the investor takes 20%. The investor also requires a 10% ESOP pool created inside the pre-money. Result: founders 70%, seed investor 20%, ESOP pool 10%.
Series A. A new fund buys 25% of the company, so every existing holder is multiplied by 0.75. Founders drop to 52.5%, the seed investor to 15%, the ESOP pool to 7.5%, and the Series A fund holds 25%.
Series B. The next fund buys 20%, so existing holders are multiplied by 0.8. Founders land at 42%, seed at 12%, ESOP at 6%, Series A at 20%, and Series B at 20%.
Across three rounds the founders went from 100% to 42%, without a single unfair event, and on a company now worth many times what it was at seed.
India compliance to remember
- Valuation: an unlisted priced round needs an IBBI-registered valuer report to justify the share price.
- Foreign investors: if any investor is resident outside India, the company must file Form FC-GPR on the RBI FIRMS portal within 30 days of allotment, as required under FEMA.
- ESOP for founder-directors: for up to ten years from incorporation, a DPIIT-recognised startup may grant options to promoters and directors holding more than 10%, an exemption ordinary companies do not have.
Model your cap table before you raise, not after. Multiply your stake by each round's retention factor, decide the ESOP pool size consciously, and you will always know what you are giving up and why.
