Cassidy

Cassidy is a New York-based enterprise AI platform that lets non-technical teams build AI agents and multi-step automations powered by their own internal company data. By connecting large language models to a business's knowledge base, tools, and real-time data, Cassidy automates complex, context-heavy workflows - customer support triage, RFP responses, CRM updates from sales calls, lead qualification and internal knowledge sharing - without writing code. Founded in 2023 by Justin Fineberg and Ian Woodfill, the company raised a $10M Series A in 2025 and is used by more than 20,000 teams.
