Seed funding is the earliest stage of formal outside investment in a new company, typically raised after the founders have used their own savings and help from friends and family. The money is meant to plant the "seed" of a business: hire the first staff, build an early version of the product and gather evidence that customers want it. Seed investors accept a high risk of total loss in exchange for a stake that could become very valuable if the company succeeds.
Seed rounds sit before the priced Series A and Series B rounds led by venture capital firms. A smaller "pre-seed" round sometimes comes first. In crypto, seed rounds often buy rights to future tokens as well as, or instead of, shares, which brings extra legal and market questions.
Seed funding in plain terms
Imagine a cook who wants to open a restaurant but only has a recipe and a few dinner-party fans. Before any bank will lend, the cook needs to prove that strangers will pay for the food. A handful of people who believe in the cook chip in enough to rent a market stall for six months. If the stall is busy, bigger backers will fund a real restaurant; if not, the early money is gone.
Seed investors are those first backers. They put in small amounts relative to later investors, but at a much earlier and riskier moment, which is why they expect a larger share of the business for each dollar they invest.
Who provides seed funding
- Angel investors. Wealthy individuals, often former founders, invest their own money and frequently offer advice. See angel investor.
- Accelerators. Programmes such as Y Combinator, founded in 2005, invest a small amount in many start-ups at once and provide mentoring and a demo day for later investors.
- Seed funds. Venture firms that specialise in early rounds, often investing alongside angels.
- Crowdfunding. Platforms that let many small investors take part, under rules for crowdfunding that vary by country.
- Corporate and crypto funds. Large companies and, in crypto, foundations of established blockchains sometimes fund young projects in their ecosystem.
In the United States, most private start-up investments are restricted to an accredited investor unless an exemption such as regulated crowdfunding applies.
Instruments and terms
Seed money usually comes through one of three instruments:
- SAFEs. The simple agreement for future equity, introduced by Y Combinator in 2013, converts into shares at a later priced round, often at a discount or subject to a valuation cap.
- Convertible notes. A convertible note is a short-term loan that converts into equity later, with interest and a maturity date.
- Priced equity. Investors buy shares at an agreed valuation, set out in a term sheet.
Founders typically give up a meaningful minority of the company in a seed round, and each round's effect on ownership is tracked in the cap table. Round sizes and valuations vary widely by country, sector and market conditions and have risen and fallen with the venture cycle.
Before investing, seed backers carry out lighter due diligence than later investors, since there is little financial history to examine. They focus instead on the founding team, the size of the market and any early signs of product-market fit, such as a waiting list, pilot customers or rapid user growth. Many seed investors also reserve money to invest again in later rounds of the companies that do well.
Seed rounds in crypto
Crypto start-ups often raise seed money through token warrants, which give investors the right to receive tokens if a network launches, or through a simple agreement for future token. Seed investors usually buy at the lowest price of any round, and their tokens are locked and released over time under a cliff vesting or linear schedule. When those tokens unlock, early holders may sell, which can weigh on the market price. Public token buyers often look at what share of supply went to seed investors and at what price, since a large discount can mean heavy selling later.
Risks and criticism
Most seed-funded companies fail or return little, and investors rely on a few big successes to make up for many losses. Founders face their own risks: generous terms in an early round, such as low valuation caps, can leave them with a small share after later rounds. Seed investments are illiquid and may take a decade to pay off, if ever. In crypto, critics argue that cheap seed allocations transfer value from public buyers to insiders, a concern linked to high fully diluted valuations at launch. None of this is advice to invest.
