Instead of asking “Who do you know?” , our protocol asks “What does your reputation prove?” We filter and score founders, investors, and partner contributors through privacy-preserving AI agents trained on onchain data, trust graphs, and encrypted narratives. We are building a future where access to capital is earned through proof , not persuasion. Role Overview: We are hiring 2 AI Agent Engineers who will initially join as part-time contributors, with a clear path to full-time roles in the core protocol team. You’ll collaborate with our engineering and AI research leads to design, test, and scale modular AI agents in areas like identity scoring, raise prediction, and decentralized traction mapping. This role is solo-first, ownership-driven, and deeply technical — perfect for builders who want to shape foundational systems from the protocol layer up. What you will build: You’ll take full ownership of one or more of the following agent categories (based on your strengths): Identity Model Agent: Score founder/investor credibility via DID-linked history and encrypted onchain data. Pitch Strength Agent: NLP-based evaluation of pitch narratives using local language model fine-tuning. Fundraise Prediction Agent: Forecast raise success using hybrid models (quantitative + qualitative). Investor Archetype Agent: Cluster investor behavior using wallet data and confidential profiling logic. Social Trust Graph Agent: Construct trust-based scoring from verified relationships and zero-knowledge attestations.
