What Is a Pre-Seed Funding?
Pre-seed funding is the earliest outside money a startup raises, commonly from founders' networks, angels or small funds, to test an idea and build a first version.
How it works
Pre-seed money pays for the very first steps: building a prototype, talking to customers, and proving there is something worth building. The company usually has little or no revenue. Investors are betting mostly on the founders and the idea, since there is little data to judge.
Typical sources are friends and family, angel investors, small pre-seed funds and accelerators. The instrument is often a SAFE or convertible note rather than priced shares, because it is quick and cheap to paper. Round sizes vary widely by city, industry and year, so treat any figure you read as a rough guide only.
Pre-seed vs seed
The labels are informal and the line is blurry. In general, pre-seed funds getting to a first working product and early user signals. Seed funding typically comes once there is a working product and some evidence of demand, and it funds the work of finding repeatable growth. Seed rounds are commonly larger and more likely to involve a lead investor and a formal valuation process. Some investors use the two words interchangeably, so ask what a person means by them.
Example
Suppose two founders raise $250,000 on SAFEs from five angels. They use it for 12 months of modest salaries, a contract developer and customer research. At the end they have a working beta and 15 pilot users, which gives them something concrete to show seed investors.
Common mistakes
- Raising more than the idea justifies, which means giving up ownership for money you cannot yet use well.
- Raising too little to reach any meaningful milestone.
- Skipping legal basics such as incorporation and an IP assignment from each founder before taking money.
- Not tracking who holds which SAFE or note, which makes the next round messy.
