First Round is a venture capital firm that works with founders exclusively at the earliest stages of company building, often when all they have is an “imagine if.” We fill in where we can until the team is filled out, tackling crucial early hiring and equipping those who are great at building product with the skills to sell it, too. By getting the foundational firsts right, we increase the odds of finding extreme product-market fit. Our founders’ “imagine ifs” have turned into companies like Notion, Roblox, Uber, and Square.
