Short answer

Pre-seed funds the search for product-market fit: a team, a product or prototype, and early signs of demand. Seed funds the first repeatable growth: retained users, early revenue and a channel that works. Pre-seed is usually a SAFE or convertible loan from angels and small funds; seed is often larger, sometimes priced, and led by a fund.

What changes in the pitch?

Pre-seed pitches lead with the team and insight; seed pitches lead with numbers. See the pre-seed pitch deck and traction metrics before revenue. For the full process, read how to raise a pre-seed round.

What is a "pre-seed extension" or "seed+"?

When a company has made progress but not enough for the next stage, it often raises a small extension on similar terms. This is common and not a bad signal by itself, as long as the extension is tied to a specific milestone. It does add another layer of dilution, so model it with our SAFE example.

How does Europe differ?

European rounds at each stage have historically been smaller than in the US, and the instruments differ: German companies often use convertible loans or small notarised capital increases instead of SAFEs. Many European seed funds also expect more traction before they lead. The labels are the same; the bar can be different. Read Delaware C-Corp vs GmbH if you plan to raise from both sides of the Atlantic.

What is the honest self-test?

Write your traction slide today, without adjectives. If it shows a team, a product and early usage, you are raising pre-seed. If it shows retained users growing through a repeatable channel, you are raising seed. Then match your target investors, your amount and your cap to that answer.

Frequently asked questions

What is the difference between pre-seed and seed?

Pre-seed funds finding product-market fit; seed funds the first repeatable growth. Seed investors expect stronger evidence such as retention and revenue.

Can you skip pre-seed and raise a seed round?

Yes, if you already have the evidence seed investors expect, often thanks to bootstrapping or strong early traction.

Is pre-seed always a SAFE?

In the US it is usually a SAFE. In Germany it is more often a convertible loan or a small priced round.

How much equity is sold in a seed round?

Commonly around 10–25%, depending on market conditions and the company's progress.
