Thesis

Crypto-native operators architecting token-first networks through deep cryptoeconomic design, governance innovation, and sustainable token economies. 1kx supports builders across infrastructure, middleware, and consumer applications, focusing on projects that advance the decentralized future. The fund partners with founders to scale transformative blockchain projects while maintaining alignment through long-term capital commitment and deep technical expertise.

Likely not a fit for

Purely marketing-driven projects without differentiated technology. Centralized platforms disguised as decentralized. Projects with poor tokenomics or misaligned token design. Late-stage cryptocurrency projects outside of follow-ons. Non-blockchain projects where blockchain is unnecessary. Meme coins or pure speculation plays. Copy-paste blockchain implementations. Founders without demonstrated crypto/cryptography knowledge.
