Elphadel is an applied AI research lab with the mission of making institutional-grade quantitative investment research accessible to everyone.

We are a San Francisco-based team bringing together quantitative research and trading experience from Citadel, Five Rings, and Optiver, automated research experience from neolab led by former head of OpenAI's automated trading research team, and academic research experience from MIT CSAIL. We are backed by Y Combinator.

Our first product is Elphada, an mobile app that empowers investors to evaluate theses, explore execution methods, and build quantitative trading strategies—all through conversational, natural language prompts.
