What is a seed round?
A seed round is the equity financing transaction that capitalises a company at seed stage — typically the first institutional priced or pseudo-priced round in a company’s life, raised to fund the period from product launch through the early signals of product-market fit. The seed round is distinct from seed stage: the round is the transaction, the stage is the company’s operational state.
Seed round components
- Round size: the dollar amount raised — typically USD 1–5M.
- Valuation: pre-money and post-money. Post-money = pre-money + round size; founder ownership dilution = round size ÷ post-money.
- Instrument: SAFE (Y Combinator’s standard), convertible note, or priced preferred stock for larger rounds.
- Lead investor: typically a seed-stage VC fund that anchors pricing, leads diligence and takes a board seat or observer right.
- Syndicate: additional investors filling out the round behind the lead’s pricing.
- Pro-rata rights: the right for seed investors to maintain ownership percentage in the next round.
Mechanics: priced vs. SAFE
- SAFE: investor pays now, receives equity at the next priced round at a valuation cap and/or discount. Light, fast, founder-friendly. Best for rounds under USD 2M and where pricing is contentious.
- Priced round: investor receives preferred stock today at an agreed valuation. Heavier documents (term sheet, stock purchase agreement, investor rights agreement, ROFR/co-sale, voting agreement), but cleaner cap table and clearer governance.
What a seed round typically funds
- 18–24 months of runway to hit Series A milestones.
- First sales and marketing experiments to identify a scalable channel.
- Product investment to improve activation, retention and expansion.
- Key hires in product, engineering and go-to-market roles.
Series-A readiness as the seed goal
The job of a seed round is to make the company Series-A-fundable — typically demonstrated by USD 1–3M ARR (varies by sector), strong retention curves, and at least one repeatable acquisition channel. Failing to hit these signals leads to bridge rounds, down rounds or shutdown.
Do: negotiate the seed round with the Series A in mind — cap table, anti-dilution, board composition and pro-rata terms compound into the next round.
Don’t: chase the highest valuation at seed; an over-priced seed makes Series A markup harder and increases down-round risk.
