What's the difference between pre-seed and seed?

Updated Oct 1, 2026

Short answer: Pre-seed is usually the first outside money, often raised before real traction to build the product and find early customers. Seed typically follows early traction and funds the search for product–market fit; the exact boundary varies by market and year.

Who invests

Pre-seed rounds often come from angels, friends and small funds; seed rounds more often include dedicated seed funds, sometimes with a lead investor setting the terms.

How they're structured

Both are frequently raised on SAFEs or convertible notes, though some seed rounds are priced equity rounds.

What investors look for

At pre-seed, investors weigh the team and the problem; at seed, they increasingly want evidence such as revenue, retention or strong usage.
