What it means
The step from seed to Series A is the step from a hypothesis to evidence. Investors at this stage want to see real revenue, retention that holds up over time, and a clear picture of what it costs to win a customer and what that customer is worth.
Structurally the round looks quite different from seed. There is a lead investor who sets the price and terms, a full set of legal documents, a board seat, and preference shares that give investors a payout ahead of ordinary shareholders if the company is sold.
Almost every Series A includes an option pool for employees, and where that pool sits in the calculation matters enormously. If it is created before the money goes in, existing shareholders bear the dilution; if after, the new investor shares it, which is why the term sheet phrase about the pool being in the pre-money is worth arguing over.
The proceeds usually fund a specific eighteen to thirty month plan. That plan almost always involves hiring a sales team, building the engineering capacity to serve larger customers, and reaching metrics that make the next round straightforward.
Preference terms deserve attention. A standard one times non-participating preference means investors take either their money back or their percentage of the sale price, whichever is greater, and anything more aggressive can quietly change how founders fare in a moderate exit.
In practice
Real-world examples.
Example
A subscription analytics business raises a $9,000,000 Series A at a $36,000,000 pre-money valuation after reaching $3,000,000 of annual recurring revenue with 95% retention. Two thirds of the money is earmarked for sales and customer success hires.
Example
A consumer hardware company raises a $12,000,000 Series A led by a fund that takes a board seat and requires monthly reporting. The lead insists on a 15% option pool created before the round, which dilutes the founders rather than the incoming investor.
Example
A payments startup runs a competitive Series A process with three interested funds and uses the tension to move from a $20,000,000 to a $28,000,000 pre-money valuation. It accepts a slightly smaller cheque to keep dilution near 20%.
Formula
Calculation
Post-money valuation = pre-money valuation + amount raised
Price per share = pre-money valuation / fully diluted shares before the round
Investor ownership = new shares issued / total shares after the round
A software company with 12,000,000 shares outstanding agrees a $24,000,000 pre-money valuation and raises $6,000,000. The post-money valuation is 24,000,000 + 6,000,000 = $30,000,000.
The price per share is 24,000,000 / 12,000,000 = $2.00, so the investor receives 6,000,000 / 2.00 = 3,000,000 new shares. Total shares after the round are 12,000,000 + 3,000,000 = 15,000,000, and the investor owns 3,000,000 / 15,000,000 = 20%, which is exactly 6,000,000 / 30,000,000 as expected.
Founders who together held 60% before the round, that is 7,200,000 shares, still hold 7,200,000 shares afterwards but now own 7,200,000 / 15,000,000 = 48%. Their percentage fell by a fifth while the value of their stake, on paper, rose from 60% of $24,000,000 which is $14,400,000 to 48% of $30,000,000 which is $14,400,000. Dilution alone leaves them level; the gain comes only if the company grows from here.Case study
Seen in the real world.
Lumen Fieldworks is an illustrative, fictional company selling inspection software to utilities. It had raised $1,500,000 of seed capital, reached $2,400,000 of annual recurring revenue with two thirds of that from three large customers, and went out to raise a Series A.
The first term sheet offered $6,000,000 at a $24,000,000 pre-money valuation but required a 12% option pool inside the pre-money, which meant the founders absorbed all of that dilution. A second fund offered the same $6,000,000 at a $22,000,000 pre-money valuation with the pool created after the money went in. The founders ran the numbers and found the lower headline valuation actually left them owning more, so they took the second offer.
The fictional point is that the pre-money number on the front page of a term sheet is not the whole deal. Option pool placement, preference terms and board composition frequently matter more to a founder's eventual outcome than a couple of million dollars of stated valuation.
Watch out
Common mistakes.
- Comparing term sheets on headline valuation alone and ignoring option pool placement, which can swing founder ownership by several percentage points.
- Raising a Series A before the underlying economics work, so the extra money simply accelerates spending on a model that does not yet pay back.
- Assuming preference shares are just a formality, when participating preference or a multiple can materially reduce what founders receive in a modest exit.
Questions
People also ask.
How much revenue do I need for a Series A?
There is no fixed threshold, but investors generally want to see clear, growing recurring revenue with evidence that customers stay and that growth is repeatable.
How much of the company does a Series A investor take?
Typically 15% to 25%, with 20% being the most common outcome across the market.
What is the difference between seed and Series A?
Seed money funds finding a repeatable model, while Series A funds scaling one that has already been demonstrated with real customers.
