Startup Valuation: What It Is, How Investors Set It, and How to Raise Yours

Valuation is the number founders obsess over and the one they understand least. It feels like it should be a calculation, an objective figure the market hands you. It is not. At the early stages, a startup’s valuation is closer to a negotiated agreement than a computed fact, and knowing what actually sets it, and what genuinely moves it, is worth more than any formula.

This is the first post in the mechanics that sit beneath every round on the funding ladder. Its companion covers cap tables and dilution, the flip side of the same coin.

Pre-money and post-money

Start with the single distinction that causes the most confusion and the most expensive mistakes.

• Pre-money valuation is what your company is worth before the new investment goes in.
• Post-money valuation is pre-money plus the amount raised.

An investor’s ownership is their cheque divided by the post-money valuation. Raise 2 million dollars at an 8 million pre-money, and the post-money is 10 million, so the investor owns 20 percent (2 divided by 10). Quote the same deal as “10 million valuation” without saying which, and a founder who assumes pre-money has just given away more than they think. Always be explicit about which number you are discussing, because the gap between the two is exactly the size of the round.

How early-stage valuation is actually set

Here is the uncomfortable truth: at pre-seed and seed, there is usually too little data for a formal valuation method to mean anything. Discounted cash flow models, which value a company on its future cash, are close to fiction when a company has no revenue and no history. So investors do something more practical. They anchor.

They look at what comparable companies, at the same stage, in the same sector and geography, recently raised at, and they start there. Then they adjust up or down for your specific traction, team and market, and for how competitive the round is. The valuation that emerges is a negotiated meeting point between what you can justify and what the investor is willing to pay. This is why the instruments that defer valuation, SAFEs and convertible notes, are so common early on: they let you avoid an argument that neither side can win with data.

To ground it in real numbers, Carta’s 2025 data puts the US median pre-money valuation at roughly 16 million dollars at seed (up about 18 percent year on year), 49 million at Series A and 119 million at Series B. Those are the anchors US investors carry into the room. African valuations typically sit well below them.

What actually moves the number

If valuation is negotiated, what gives you leverage in the negotiation? Four things, in rough order of power.

1. Traction. Real evidence the business works, revenue, growth, retention, moves valuation more than anything else, because it reduces the investor’s risk.
2. The team. A credible, experienced team, especially with relevant founder-market fit, commands a premium, particularly when there is little else to judge.
3. Market size. A genuinely large market raises the ceiling on the outcome, and investors price for the ceiling.
4. Competition for the round. This is the most underused lever. A round with several interested investors prices higher than one with a single reluctant one, every time. Creating real investor interest is not just about closing the round; it is a valuation tool in itself.

Notice what is absent: a spreadsheet formula. The financial model matters, but as evidence that you understand your business, not as the source of the valuation number.

The highest valuation is not the best deal

Founders instinctively chase the highest valuation. Often they should not. A valuation is a promise about the future: it sets the bar you must clear at your next round. Price this round too richly and you create a trap. If you cannot grow into the valuation, your next round is a down round, raised at a lower price than the last, which is damaging to morale, to your cap table, and to your reputation, and can trigger the anti-dilution penalties we cover in the term sheet post.

This is not hypothetical. Down rounds reached a decade high of roughly 20 percent of all rounds in 2025, according to PitchBook, as companies that raised at inflated valuations in the boom struggled to justify them. A fair, defensible valuation you can beat next time is almost always a better outcome than the highest number you can extract today.

The African context

Valuing an African startup carries extra wrinkles. Comparable deals are scarcer, so the anchoring that sets valuations elsewhere is harder, which can leave African founders under-priced simply for lack of reference points. Most rounds are struck in US dollars, so the valuation is a dollar figure even though the business earns in local currency, and a devaluation can quietly erode the real value an investor believes they bought, a dynamic worth understanding alongside our piece on managing currency risk. Development finance institutions and impact investors, more common on the continent, may also weigh factors beyond pure financial return. The practical takeaway is that genuinely clean traction and numbers matter even more in African rounds, because they give you the hard evidence to argue a fair valuation where easy comparables do not exist.

What good looks like

You are handling valuation well when you can name a defensible number, explain the comparable deals and the traction behind it, and hold a fair price without either underselling the company or reaching for a figure you cannot defend next year. Then the real consequence of that number, how much of the company you give up, plays out on your cap table, which is where this mechanics series goes next.
