Investment portfolio

  • Derivio

    Participated · Equity · Mar 2026

    Derivio builds a full-stack trading terminal optimized for AI-driven or "agentic" trading, combining a high-speed data engine that ingests on-chain signals and market ticks with optimized execution routing and physical node placement. The platform emphasizes non-custodial operation, advanced risk-management features, a universal margin system for multi-asset collateral, and planned Liquidity-as-a-Service (LaaS) market-neutral setups. Derivio’s interface includes an "Agent" section (reported as "coming soon") that will let users deploy AI agents to monitor markets and execute strategies autonomously. The company aims to expand asset and chain coverage and improve capital efficiency for traders and liquidity providers. Following a $6 million financing round in March 2026, Derivio plans to accelerate development of its agentic infrastructure, data engine, and user-facing features to bring its AI-native workflows to market.

  • Delphi

    Participated · Series A · Jun 2025

    Delphi enables people to create Digital Minds: interactive AI representations grounded in their own writing, documents, videos, podcasts, frameworks, experiences, and ideas. These Digital Minds can answer questions, provide context, and interact via text and voice while evolving as new knowledge is added. The technology is already being used by founders, investors, professors, experts, creators, and leadership teams, suggesting early adoption across individual and organizational users. Delphi’s CEO is Dara Ladjevardian, who is participating in industry conversations about agentic AI and governance. The company’s work raises questions about identity, provenance, authority, and when such systems should be allowed to take actions, topics the company is engaging with publicly.
