Series A
A Series A is a startup's first large priced round of venture capital, raised once a product has found paying customers and the question has changed from whether it works to how fast it can grow. It is led by a venture fund that takes a board seat and preferred shares with a liquidation preference, and it is the round that turns a founding team into a company with governance.
- Also known as
- Series A round, A round
- Used at
- after seed, typically at $1–3m of annual recurring revenue for software or the equivalent proof for a fintech — a licence, volume through a partner bank, unit economics that work
- Binding
- yes — a term sheet, then a shareholders' agreement and articles that set the preferred shareholders' rights for every round that follows
- Typical size
- $8–20m in the US and Europe in 2024–2025, larger for fintechs with capital-intensive models
- Typical valuation
- pre-money of $30–80m; the round buys 15–25%; a 1× non-participating liquidation preference is the market standard
- Parties
- the lead investor, participating seed investors exercising pro-rata rights, founders, and the company's lawyers, who draft what the founders will live with for years
How a Series A works in practice
The lead investor sets the terms and the others follow. A term sheet fixes the price, the amount, the option pool — usually enlarged before the round so that the dilution falls on existing holders — and the preferred rights: a liquidation preference, so that on a sale the investor gets its money back before the common shares share the rest; anti-dilution protection, in case a later round is priced lower; pro-rata rights to keep its stake in later rounds; a board seat; and consent rights over a sale, new debt, new shares and changes to the business. Diligence follows — commercial, financial, legal, and for a fintech regulatory — and the definitive documents take four to eight weeks.
What the money is for is the growth plan the round was raised on: the sales team, the second market, the licence in the next jurisdiction. The board that now exists will measure the company against it every quarter, and the next round is priced on whether it was met.
For a fintech the Series A lead also underwrites the regulatory path. A company operating under a partner bank's licence will be asked how it gets its own; one with its own licence will be asked how much capital that licence will demand as it grows, because that capital will come from the Series B.
Example
A lending fintech with £1.8m of revenue raises a £12m Series A at a £48m pre-money valuation: £60m post, 20% to the round. The lead takes £9m, two seed funds take £3m pro rata, and the option pool is topped up to 12% of the post-money company beforehand. The preferred shares carry a 1× non-participating preference. If the company sells for £40m two years later — below the post-money — the Series A holders take their £12m first and the remaining £28m is shared by everyone else by shareholding; if it sells for £300m they convert to common and take their 20%, £60m, because that is more than £12m. Between the two the preference is the term that decides who gets what.
Common mistakes
- Raising the A on the seed's metrics and being priced as a seed. - Accepting a participating preference or a multiple above 1× because the headline valuation was higher. - An option pool sized to the investor's request and taken entirely from the founders before the round. - A board with an investor majority after one round. - Modelling the plan without the regulatory capital the licence will require at the scale the plan reaches.
