Most often the issuing startup proposes the valuation cap in seed-stage convertible instruments such as SAFEs or convertible notes, but the final number is the product of negotiation with investors. Templates from Y Combinator make it simple for founders to offer capped instruments, yet experienced investors or a lead backer frequently influence or insist on the cap. Founders initiate terms to attract capital while lead investors shape those terms to protect their expected equity position.
Negotiation dynamics and causes
Bargaining power drives who effectively sets the cap. When a founder has strong market traction or multiple competing offers, the entrepreneur can set a higher valuation cap. When a single investor is committing significant capital or coordinating a syndicate, that investor commonly negotiates the cap and other protections. Brad Feld and Jason Mendelson, Foundry Group explain in Venture Deals that term-setting power often falls to the party providing the largest portion of the round, because that party assumes outsized risk and administrative burden. Market conditions, comparable deals in the region, and legal templates such as the SAFE from Y Combinator shape expectations and practical starting points for negotiation.
Consequences and regional nuances
Who sets the cap affects dilution, signaling, and future fundraising. A cap set too low can accelerate founder dilution at conversion and signal weak negotiating leverage to later-stage investors; a cap set too high can make the current round less attractive to seed investors and create valuation cliffs in subsequent priced rounds. Cultural and territorial norms matter: in Silicon Valley SAFEs and founder-proposed caps are common, whereas in other ecosystems investors may demand more bespoke terms or use priced rounds earlier. Local legal practices and investor networks influence what is considered reasonable, and that shapes startup behavior across different regions.
Understanding who sets the cap therefore requires looking at templates, the balance of power in the room, and the strategic preferences of both founders and lead investors. Valuation cap is as much a financial number as it is a negotiated expression of trust and leverage between parties.
