What Is a Lead Investor?
In short
A lead investor is the investor who sets the terms of a round, usually writes the largest cheque and does most of the due diligence. Other investors often join once a lead has committed.

Worked example
You are raising a $2M seed round. A seed fund commits $1M, negotiates the term sheet at an $8M pre-money valuation and takes a board seat. With those terms set, three angels and a smaller fund fill the remaining $1M within two weeks.
The investor view
Why it matters for early-stage founders
Most rounds do not close until someone leads. A lead gives other investors confidence, so finding one is often the hardest and most important step of a raise.
Watch out
The common mistake
Collecting small soft commitments without a lead. Without agreed terms, those investors rarely send money, and the round stalls.

- Term sheetA term sheet is a short, mostly non-binding document that sets out the main terms of an investment: how much is invested, at what valuation, and what rights the investor gets. Once both sides sign it, lawyers turn it into the final legal documents.
- Due diligenceDue diligence is the checking an investor does before committing money. They verify that what you told them is true: your company records, ownership, contracts, numbers, product and team.
- Pro rata rightsPro rata rights give an investor the option, but not the duty, to invest in your next rounds so they can keep the same percentage of the company.
- Pitch deckA pitch deck is a short presentation, usually 10 to 15 slides, that explains your problem, solution, market, traction, team and ask, so investors can decide quickly whether to take a meeting or invest.
