Investment portfolio

  • SpaceComputer

    Participated · Seed · Nov 2025

    SpaceComputer is a cybersecurity company focused on building encryption systems that are resilient to sophisticated attacks by leveraging satellite infrastructure. Its debut product, ctRNG, taps into entropy generated in space to create true random numbers, a critical component for high-grade cryptographic applications. The company plans to expand this technology into a full satellite-based, attack-resistant encryption platform. Recently secured seed financing provides the capital needed to accelerate R&D on these next-generation systems. Although still early-stage, the successful launch of ctRNG demonstrates initial product-market validation and technological feasibility. The $10 million in seed funding is the company’s primary financial backing disclosed to date and positions it to deepen product development and pursue early commercial partnerships.

  • Bluwhale

    Participated · Series A · Oct 2025

    Bluwhale offers a consumer-first platform that matches a user’s financial health score with an AI agent marketplace, enabling enterprises and developers to launch always-on financial services for a digitally native Gen Z audience. The company’s Layer-3, multi-chain infrastructure supplies data, storage, and compute to hundreds of AI agents that recommend assets and execute transactions securely on blockchains. Bluwhale’s ecosystem now serves more than 3.6 million users worldwide, positioning it as a leading real-world application of AI and blockchain convergence. On October 21, 2025 the firm conducted a Token Generation Event for $BLUAI, the native token that fuels its decentralized AI network. Management plans to direct new capital toward broadening institutional partnerships and integrating AI agents into everyday financial applications. By targeting the forthcoming wealth transfer to Millennials and Gen Z, Bluwhale aims to modernize financial services that remain reliant on physical branches and manual processes. Backing from both global banks and leading blockchain foundations underpins the company’s strategy to build secure, scalable, and interoperable AI for traditional and Web3 markets.

  • USD.AI

    Participated · Series A · Aug 2025

    USD.AI, developed by Permian Labs, operates a stablecoin-based lending protocol that accepts GPUs as collateral to underwrite credit for AI startups. The protocol issues USDai (a dollar-linked token) and sUSDai (a yield-bearing version backed by revenue-generating compute assets). USD.AI says its GPU-collateral model reduces loan approval times by more than 90% compared with traditional lenders. The company targets small AI firms that are often excluded from conventional financing channels. During a private beta USD.AI collected $50 million in deposits. It plans a public launch that will include an initial coin offering (ICO) and a game-based token allocation model.
