Seed round

As explained in Tech Startup Toolkit

Seed financing is an early startup funding round that typically precedes Series A financing.

You have a real company, a clear problem to solve, and perhaps a prototype—but no product revenue yet. A seed round is the first formal, priced equity financing round: a new investor sets a price per share in exchange for ownership. It usually comes before Series A and gives an early startup funding plus practice for later, tougher financings. section 5.2 section 10.0

Seed is not just “getting some money.” It is a structured transaction with lawyers, documents, and a new seed preferred-share class for investors; founders and employees generally hold common shares. The agreed price affects ownership, so the cap table—the record of company securities and ownership—matters from the start. section 10.3 section 10.2

A practical readiness check:

  • Form a real company, generally a C corporation. section 10.3
  • Articulate the product or service clearly; a demonstrable prototype is better. section 10.3
  • Do not assume customers are required. Some seed investors ask for them, but that expectation is more typical of Series A. section 10.3
  • Seek investors suited to the stage: organized angel groups, small VC funds, and occasionally large VCs with dedicated seed funds. section 10.2

A seed extension is not automatically failure

A startup can spend its initial seed cash before it qualifies for Series A. Rather than force an A too early, it may raise Seed II: additional seed capital while concentrating on the milestones needed for Series A. Raising too high a round before proving product-market fit can make a later down round especially damaging. section 10.0 section 10.7 section 10.8

The goal is to use seed as a disciplined warmup: find and pitch investors, compare lead candidates and term sheets, close the financing, then turn the cash into progress toward Series A. A seed round can help, but it is not mandatory; a company can qualify for Series A without having raised one. section 10.8 section 10.7
