What it means
At seed stage there is usually no reliable revenue history, so investors are backing a team and a hypothesis rather than a set of numbers. That makes valuation more of a negotiation about ownership percentages than a calculation from earnings or cash flow.
The money is nearly always spent on reaching a specific milestone rather than on general operations. Common milestones include shipping a first product, signing a handful of paying customers, or proving that acquiring a customer costs less than the revenue that customer generates.
Seed rounds are often structured as convertible instruments rather than priced equity. A convertible note or a simple agreement for future equity lets the company take money now and settle the ownership question at the next priced round, which saves time and legal cost when a fair valuation is genuinely hard to pin down.
The single most useful number at seed stage is runway, which is how many months the money lasts at the current rate of spending. Investors and founders both track it closely, because raising the next round takes three to six months and you need to start that process well before the cash runs out.
Dilution is the unavoidable trade. Selling 20% of the company at seed feels expensive when you own everything, but 80% of a funded company that reaches its milestone is generally worth more than 100% of an unfunded one that does not.
In practice
Real-world examples
Example 1
A hardware founder raises $400,000 of seed capital from three angel investors to build fifty production units and test them with pilot customers. The round is done on a convertible note so that pricing the company can wait until the pilots produce real data.
Example 2
A two-sided marketplace raises $2,000,000 of seed capital at an $8,000,000 pre-money valuation, giving investors 20%. Nearly all of it goes into paid acquisition on one side of the marketplace, because supply density is the thing that determines whether the model works at all.
Example 3
A biotech spinout takes $750,000 of seed capital from its university's investment arm alongside a research grant. The grant funds the laboratory work while the equity money funds the commercial hires the grant will not cover.
Think of it
Seed capital is like buying the soil, pot, and water for a single plant seed, keeping it alive until it grows strong enough to gather its own sunlight and nutrients.
Formula
Calculation
Post-money valuation = pre-money valuation + amount invested
Investor ownership = amount invested / post-money valuation
Runway in months = cash raised / net monthly burn
A two-person analytics startup agrees a pre-money valuation of $6,000,000 and raises $1,500,000 of seed capital. The post-money valuation is 6,000,000 + 1,500,000 = $7,500,000, and the investors own 1,500,000 / 7,500,000 = 20% of the company.
The founders, who held 100% before the round, now hold 100% - 20% = 80% between them. If they had previously split ownership evenly, each moves from 50% to 40%.
The company plans to spend $110,000 a month and expects $35,000 a month of early revenue, giving a net burn of 110,000 - 35,000 = $75,000. Runway is therefore 1,500,000 / 75,000 = 20 months. Because the next raise will take about five months to complete, the team sets an internal deadline to begin at month fifteen rather than month nineteen.Case study
Seen in the real world
Tallow Lane Foods is an illustrative, fictional plant-based snack brand that raised $1,200,000 of seed capital at a $4,800,000 pre-money valuation, giving investors 20% of a $6,000,000 post-money company. The founders planned to use the money to move from a shared commercial kitchen to a contract manufacturer and to win listings with two regional grocery chains.
Six months in, net burn had crept from a planned $60,000 a month to $95,000 because the team hired a sales director earlier than budgeted. Runway fell from twenty months to roughly thirteen, and the founders faced a choice between cutting the hire or starting the next raise immediately. They chose to raise early on slightly worse terms, accepting a further 18% of dilution rather than risking a cash crisis.
This fictional example shows why seed-stage boards obsess over burn rather than valuation. A good headline valuation is worth very little if the money underneath it runs out before the milestone is reached.
Watch out
Common mistakes
- Optimising for the highest possible seed valuation, which can make the next round painfully hard if performance does not catch up with the price.
- Treating seed capital as general operating money instead of tying it to one clearly defined milestone that makes the next round raisable.
- Ignoring how convertible notes stack, so that founders are surprised by the total dilution when several notes convert at the same discount in one round.
Questions
People also ask
How much of a company do seed investors usually take?
Somewhere in the region of 10% to 25% is common, with the exact figure depending on the amount raised and how much traction already exists.
Is seed capital the same as pre-seed?
Not quite; pre-seed is typically a smaller first cheque used to build a prototype, while seed money funds the push towards paying customers.
Does seed capital have to be repaid?
No, it is equity rather than debt, though convertible notes technically carry a repayment right that is very rarely exercised in practice.
