IGNITE EXTENDED / LESSON 31
How do later rounds change today’s ownership requirement?
A multiple-round capitalization and VC-method calculation.
The source first projects an exit value from revenue and a valuation multiple. It then calculates how much value an investor’s stake must return to meet a target multiple. Dividing the required proceeds by the projected exit value gives the required ownership at exit.
This is a negotiation and valuation model driven by assumptions. Revenue, the exit multiple, financing needs and the target return can all change. Show those inputs explicitly and avoid treating the resulting valuation as an independently observed market fact.
The source’s second example introduces another round: 50m invested after two years, targeting 20×. At the same 4,000m projected exit, that investor requires 1,000m of proceeds and therefore 25% of the company at exit.
The first investor still needs 10% at exit. Because the later round leaves old holders with 75%, the first investor must initially own 10%/75% = 13.333%. The corresponding current post-money value is 10m/13.333% = 75m, rather than the 100m from the one-round example.
The VC needs 40 x $10M = $400M at exit. An exit of 5 x $800M = $4B means the VC needs 10%. Applying that 10% to today's $10M gives an implied post-money of $100M and a pre-money of $90M, annotated 'Really?'.
The valuation is an output of four assumptions (exit revenue, exit multiple, target multiple, investment size), not an observed price. The 'Really?' is the right reaction: change any input and the $100M moves. With no later rounds, the stake bought today is also the stake held at exit, which is rarely true.
At the $4B exit VC2 needs $1B (25%) and VC1 needs $400M (10%), leaving founders and others $2.6B (65%). Working backward: round 2 post-money = $50M / 25% = $200M (pre $150M), and VC1 must start with 10% / (1 - 25%) = 13.3%, so round 1 post-money = $10M / 13.3% = $75M (pre $65M).
Solve the last round first, because each earlier investor's starting stake depends on everything sold after it. The later round costs VC1 a quarter of its stake, so the round-1 valuation falls from $100M to $75M with no change in the company's prospects.
When each round sells a fraction of the enlarged company, earlier holders retain the product of the fractions left after those rounds. Adding the percentages sold generally gives the wrong answer because the percentages use different denominators.
Track share counts to verify the percentage shortcut. Include option-pool changes and converting instruments when the agreed basis requires them. A model that treats all rounds as simple common-equity issuances cannot describe every negotiated financing structure.
A fully diluted percentage can be used to estimate simple pro-rata proceeds only under the rights and capital-structure assumptions of the model. Later preferences, debt and transaction costs can alter the amount a holder receives.
The source’s multi-round return chart combines ownership changes with a common hypothetical exit. It demonstrates why a later investor can have a smaller return multiple at the same exit value. More capital, a higher entry valuation and less remaining time can produce a different investment proposition.
Illustrative percentages: founders 80% / seed 20%, then founders 60% / seed 15% / new investor 25%.
A stacked chart and table for seven rounds (pre-seed $1M at $11M post through Series E $200M at $2.7B post), with each investor's return multiple at a $4B exit falling from 63.0x (pre-seed) and 40.8x (seed) to 1.5x (Series E). A handwritten note says a seed investor can realistically only offer $30M post-money.
Later investors pay higher prices with less time left, so the same exit gives them far lower multiples. That is why the 40x target belongs to seed money and 3x to growth money. The seed stake shrinks from 33% to about 10% by exit. Dividing out only the stakes sold in each round leaves 13.5%, so the chart also includes dilution the table does not show, probably pool refreshes. Reconcile share counts before relying on such a chart.
After the pre-seed: founders 10,000,000 (90.9%), pre-seed 1,000,000 (9.1%). After the seed: founders 10,000,000 (51.5%, $15.45M), pre-seed 1,000,000 (5.2%, $1.55M), seed 6,470,588 at $1.55 (33.3%, $10M), option pool 1,941,176 (10.0%, $3M); total 19,411,765 shares and $30M.
The 'Price per share' column shows $1.00 for the pre-seed investors, which is their entry price. At the seed every share is worth $1.545, which is why their 1,000,000 shares appear at $1,545,455. The $3M pool line is the part of the '$20M pre-money' that existing holders never receive.
Carta reported a median Series A post-money of $60M across 2025 ($75M for AI companies, $55M for others), and median Series A dilution of 18% for software rounds raised in the six months to July 2026. Relay's founders' ask, $12M for 20% at $60M post, is close to the median; the lead's $48M is an argument built from its own model.
The median time from seed to Series A on Carta reached about 2.1 years in 2025, up from 1.5 years five years earlier, and Series A to B reached 2.5 years. About 29% of seed and Series A rounds were bridges. A VC model with clean A-to-B steps understates dilution unless it allows for a bridge.
Carta found that AI companies took 58% of cash raised at Series D in 2025, while AI's share of early-stage dollars held roughly steady. A Series B investor in Relay Scheduler will compare it with AI-native peers on gross margin (about 72% for v2) as well as on growth.

Projected exit revenue is $800m at a 5× valuation multiple. Investor 1 contributes $10m now and targets 40× proceeds. Investor 2 contributes $50m after two years and targets 20× proceeds. Use simple pro-rata ownership, no other dilution and the source’s target-multiple model.
Calculate each required exit stake, investor 1’s initial stake, and pre- and post-money values for both rounds.
Month 30. Relay raises $12,000,000. The lead targets 10x in six years and projects year-6 revenue of $100M at a 6x revenue multiple, an exit of $600M (illustrative). Maya and Daniel ask for $48M pre-money ($60M post). The lead expects Relay to need a Series B that sells 20% before exit and argues that its model supports only $48M post-money. Post-seed, Relay has 17,102,041 fully diluted shares; Maya holds 30.41%.
Write the VC-method calculation from both sides, a sensitivity table (exit value x later dilution), the Series A cap table under $60M and $48M post-money, and a recommended negotiating position with the arguments for it.
Selling 20% and then 20% leaves 64%, not 60%, because each round is sold from an enlarged company. Multiply the fractions kept, and check against share counts: Maya goes from 30.41% to 24.33% to 19.46%, not to 18.24%.
An early investor's required stake today depends on every round after it. Start from exit ownership, divide by the fraction left after each later round, and only then compute today's post-money ($12M / 25% = $48M).
A 10x target, a $600M exit and 20% future dilution are assumptions. Run a sensitivity table before negotiating: the implied post-money ranges from $32M to $80M across plausible inputs.
A Series A pricing memo for Relay: the lead's VC-method calculation ($48M post) and the founders' ($60M post), a sensitivity table, cap tables for both prices, and a negotiating position with fallback.

Question 1
Relay's Series A lead invests $12M, targets 10x, and projects a $600M exit. Ignoring any later rounds, what ownership must it hold at exit?
Required proceeds = 10 x $12M = $120M; $120M / $600M = 20%. The 25% answer is the stake needed today if a later round sells 20%, which is the next step of the method, not the exit requirement.
Question 2
The lead now expects a Series B that sells 20% of Relay before the $600M exit. What post-money valuation does its VC method imply for the $12M Series A?
The lead needs 20% at exit, so it must start with 20% / 0.80 = 25%; post-money = $12M / 25% = $48M. $36M is the matching pre-money. $60M ignores the Series B.
Question 3
Maya holds 30.41% after the seed. Relay then sells 20% in the Series A and 20% in a Series B, with no pool top-ups. What does Maya hold after the Series B?
Multiply the fractions kept: 30.41% x 0.80 x 0.80 = 19.46%. Subtracting 40% of her stake (30.41% x 0.60 = 18.24%) treats both rounds as sold from the same denominator; 10.41% subtracts percentage points.
Question 4
If the lead's projected exit rises from $600M to $800M while the 20% Series B assumption stays, what Series A post-money does its VC method imply?
Required exit stake = $120M / $800M = 15%; today's stake = 15% / 0.80 = 18.75%; post-money = $12M / 18.75% = $64M. A 33% rise in the exit assumption moves the implied valuation by 33%, because the method is linear in the exit value.
Question 5
If the lead accepts $60M post (20%) and the Series B still sells 20%, what does it earn at a $600M exit, and how should Maya use that?
20% x 0.80 = 16% at exit, and 16% x $600M = $96M, or 8.0x (about 41% a year over six years). Most funds would be pleased with that outcome. The 10x target is a hurdle the lead uses to price risk and support its negotiating position, not a binding rule.
Question 6
The lead says: 'Our VC method gives $48M post, so that is what Relay is worth.' Which response is most accurate?
The method converts a target multiple and an exit guess into a price. A 10x target in place of a market cost of capital, a $600M exit and 20% later dilution are all choices. Founders can contest each input, such as pro-rata rights and a path to break-even, with evidence.
