Former Citadel quants raised $78M for the AI operating system Wall Street’s wealth managers didn’t have

▤ Summary

Moment, a fintech startup founded by former Citadel quantitative traders and researchers, raised $78M in a round led by Index Ventures with participation from Andreessen Horowitz and Avra. The company builds an AI agent infrastructure and regulatory-grade operating system that lets wealth managers deploy AI for fixed-income and equities trading, rather than creating its own LLM. Moment has signed major institutional clients including Edward Jones, LPL Financial, and Hightower Advisors, highlighting demand from large asset managers. The product emphasizes compliance, unified data models, and execution integration so AI can operate safely in regulated investment environments.
