Qu'est-ce que Pre-Seed Funding ?

Pre-seed funding is the capital raised to get a startup from idea to the point where it can attract a seed round. It is the most nascent stage of institutional or semi-institutional investment, often characterized by the smallest check sizes, the highest risk, and the least formal processes. Pre-seed rounds typically range from $100,000 to $2 million, though the market has stretched considerably upward in recent years for strong founding teams.

Pre-seed capital typically comes from a mix of sources: the founders' own savings (bootstrapping), friends and family, angel investors, accelerator programs (Y Combinator's $500K check being the most prominent), and increasingly, dedicated pre-seed funds that specialize in early-stage bets. The investment is almost always structured as a convertible instrument — typically a SAFE (Simple Agreement for Future Equity) or convertible note — rather than a priced equity round, because valuing a pre-revenue company is more art than science and both parties prefer to defer that conversation to the seed or Series A.

At the pre-seed stage, investors are betting almost entirely on the founding team. Traction matters — a working prototype, early users, or a letter of intent from a potential customer signals that the team can execute — but the primary diligence question is whether these founders are the right people to build this company in this market. Investors at this stage accept a high failure rate as the baseline; they are looking for the outliers that return the fund.
