RISC Zero, which is developing the Bonsai computing platform to let developers build zero-proof software, raised a $40M Series A led by Blockchain Capital

Context & Ripple Effects
RISC Zero's $40M Series A lands in the middle of a funding lane that has been building for two years: Espresso Systems raised a $29.9M Series A in 2022 to apply zero-knowledge proofs to private, scalable blockchains, and Succinct pulled in $55M across seed and Series A in 2024 for ZK proof tooling. Bonsai had already banked $13.6M before this round, so the raise roughly triples its war chest.
The lead investor matters as much as the amount: Blockchain Capital is deploying from funds it says target six sectors including DeFi and blockchain gaming, and the firm is an investor in Ripple and Coinbase — meaning this is an established crypto-native backer betting that proof generation becomes developer infrastructure rather than a niche cryptography service.
First-order effects
- RISC Zero now has $53.6M in total funding to push Bonsai toward general-purpose zero-proof software development, moving it from research project to productized platform.
- Blockchain Capital adds a ZK infrastructure position alongside its DeFi and gaming theses, giving its portfolio companies a potential verifiable-compute supplier.
Second-order effects
- RISC Zero enters direct competition with Succinct and Espresso Systems for the same developer base, pushing all three toward easier SDKs, cheaper proof generation, and broader language support as the differentiators.
- If Bonsai succeeds as a hosted proving layer, application developers stop implementing ZK circuits themselves — shifting value from cryptography specialists to whoever operates the proving infrastructure.
Third-order effects
- The pattern across RISC Zero, Succinct, and Espresso suggests zero-knowledge proofs are consolidating into a commodity infrastructure layer — verifiable compute sold as a service, analogous to how cloud providers absorbed what used to be bespoke server work.
- Combined with adjacent bets like Subzero Labs' Rialo blockchain aimed at non-crypto developers, sustained VC funding points toward proofs becoming invisible plumbing in mainstream applications rather than a blockchain-only technology.
The trend: Venture capital is treating zero-knowledge proof generation as general-purpose computing infrastructure, with successive large rounds consolidating the category around platform players.
