  • Capa

    Participated · Seed · Jul 2026

    Capa builds infrastructure to simplify buying, selling, and moving crypto in Latin America by enabling instant on- and off-ramps, reducing payment and conversion friction, and connecting multiple networks and protocols. The company is operating in Mexico and the Dominican Republic and intends to expand to additional priority LATAM markets. Following its $2.5M pre-seed raise (including a $1M extension), Capa plans to optimize its infrastructure for speed and security, integrate more blockchains and tokens, and strengthen strategic partnerships. Its strategy emphasizes user experience as the key driver of mass adoption in countries with currency volatility and limited traditional financial access. The company did not disclose revenue, users, or valuation in the announcement.

  • Octane

    Participated · Seed · Apr 2025

    Octane provides an AI-powered cybersecurity platform that analyzes smart-contract and blockchain code to pinpoint and automatically fix security flaws before they are exploited. The system combines large-scale code analysis with automated remediation, aiming to safeguard billions of dollars in on-chain assets. Led by CEO Giovanni Vignone, the company is positioning itself as a core security layer for teams building in crypto and Web3. With its newly secured seed capital, Octane plans to accelerate product development, grow its engineering and security research teams, and mass-label vulnerability data to improve model accuracy. The funds will also support broader adoption among developers integrating the platform into their continuous-integration workflows. The $6.75 million seed round represents the entirety of the company’s disclosed financing to date.

  • Lens Protocol

    Participated · Equity · Dec 2024

    Lens is a decentralized protocol designed to serve as infrastructure for social and consumer apps; users own their identity and content and apps act as clients to the blockchain. It defines social primitives — accounts, usernames, graphs, feeds, and groups — and supports developer-created rules for access control, token gating, and subscriber-only feeds. Lens v3 is a complete protocol overhaul that moves the stack from Polygon to zkSync and validiums to dramatically lower transaction costs and enable consumer-scale usage. The project powers apps on Lens v2 including Zora, Hey, Kaira, and Orb, and the team aims for interactions to cost roughly as much as cloud server costs so developers can absorb them. Avara announced a $31 million funding round for Lens, and the Lens team plans to launch the Lens v3 mainnet in the first quarter of 2025. Avara founder Stani Kulechov frames the effort around decentralization that gives users more power and enables new revenue-sharing models for creators. Lens Protocol is a decentralized social networking protocol developed by Aave aimed at creating an open, neutral layer for social apps. The protocol focuses on giving users more control over their data and enabling developers to build varied use cases from gaming to social media. Lens has been in beta since May 2022 and so far has granted access to a limited set of users while additional desktop and mobile applications are being built (Orb, Riff, Enso Collective). The team says the roadmap will remain in beta until infrastructure and the ecosystem grow sufficiently to open protocol access more broadly. Lens aims to be a flexible, neutral protocol that shares monetization across contributors rather than being owned by a single incumbent. The protocol raised $15M to expand its ecosystem and continue development; there is no valuation available.

  • Skyfire Systems

    Participated · Seed · Aug 2024

    Skyfire Systems has built an open payment protocol that gives AI agents secure wallet access, verifiable identity, and instant settlement rails so they can purchase products and services without human intervention. The platform already processes payments between AI agents and enterprises such as Emergence AI, Pricing Culture, Venice AI, Micro1, OpenRouter and Net Nut. To keep on-chain costs low, Skyfire is integrated with Base, Coinbase’s Layer-2 blockchain, where average transaction fees run below one cent. The company also supports the Coinbase Wallet, letting agents hold value and transact with other agents, companies or individuals. In just weeks since launch, the network has begun commercial payment flows for LLM aggregators and large financial-services firms. Skyfire plans to use its new capital to expand operations and accelerate product development. Following the latest raise, the San Francisco-based company’s total funding stands at $9.5 million.
