The Series A Term Sheet: A Founder's Section-by-Section Guide
Every right in your Series A definitive agreements is negotiated in the term sheet first. This guide walks through a standard Series A Preferred Stock term sheet one section at a time — offering terms, Charter, Stock Purchase Agreement, IRA, ROFR/Co-Sale, Voting Agreement, and the binding tail clauses — and shows what to negotiate, what to accept, and where founders lose the most.
TL;DR: A Series A term sheet is a miniature version of the definitive agreements. Read the header for binding provisions, circle every number (valuation, pool, thresholds, preference multiple, dividend rate), and know that protective provisions, board composition, and the no-shop are the clauses that actually determine control.
Key takeaways
- A term sheet is non-binding on the financing itself but usually binding on exclusivity, confidentiality, and expense reimbursement — read those clauses first.
- Fully-diluted pre-money valuation determines who funds the option pool refresh; model the cap table both ways before signing.
- The market Series A liquidation preference is 1x, non-participating, non-cumulative; anything else transfers economics from Common to Preferred at every exit.
- Anti-dilution should read broad-based weighted-average; narrow-based is worse, full ratchet is a red flag.
- Protective provisions are a list of future consent requests — assume each one will be exercised, especially board size and debt cap.
- Board composition (2-2-1 balanced with a mutually acceptable independent) is the most consequential control clause; do not fill the independent seat casually.
- The no-shop is the most binding clause in the whole document — push for 30 days and a fiduciary out.
- Pre-close: line up PIIAs, cap table exhibits, financial statements, and material contract list before drafts arrive — diligence gaps delay closings by weeks.
