Hi, I'm Dan π
Co-founder & CEO of Efficio and angel investor β I build and back companies at the intersection of fintech and AI. On the side, I explore the edges of AI and like small, sharp tools that solve a real problem.
What I'm into right now
- Content authenticity & provenance β proving what's human-made vs. AI-generated (C2PA / Content Credentials).
- Prediction markets β how crowds price uncertainty, and where the inefficiencies are.
- Agent & supply-chain security β keeping AI dev toolchains (npm, MCP servers) from getting owned.
What I'm building π― pm-arb-lite β a prediction-market arbitrage framework for Polymarket and Kalshi: stdlib API clients, depth-verified arb detection, a gated execution engine, and an honest backtester. It's the open, educational edition of my private trading bot: the infrastructure is real, the edge is not included.
π€ telegram-assistant β my personal AI chief of staff, living in a private Telegram chat: Gmail, Calendar, reminders, long-term memory, voice notes, and a morning briefing, powered by Claude. It's the exact assistant I use every day, open-sourced in full β multi-profile, cost-capped, one owner per bot.
π§ More soon β I ship small and iterate in public.
Investing I write pre-seed and seed checks into founders building in fintech and AI. If that's you, my inbox is open β pixi.vc.
