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.
OpenHands
OpenHands, built by All Hands AI, is an open-source, model-agnostic platform for building and running AI coding agents that can complete entire software engineering tasks - from fixing bugs and upgrading dependencies to large-scale refactors and pull-request reviews. Started in 2024 as the open-source project OpenDevin, it has grown to 65,000+ GitHub stars and 3M+ downloads, spanning a Python SDK, CLI, local GUI, and OpenHands Cloud. The company raised an $18.8M Series A led by Madrona in November 2025 to bring secure, transparent, self-hostable coding agents to enterprises.
Legion Intelligence
Legion Intelligence is a San Francisco company building a governed, agentic AI platform for national security and regulated enterprises. Formerly Yurts, it lets defense agencies and Fortune 500 teams deploy and orchestrate AI agents across cloud, on-prem, air-gapped, and classified networks (IL-2 through IL-6) using any large language model, with human-in-the-loop control and full auditability. Its platform has been fielded at U.S. Special Operations Command, the U.S. Army, and the Department of Energy, where it cut intelligence-summary creation time by 94% and saved staff hundreds of hours per week.
Unframe
Unframe is a managed AI delivery platform for enterprises that turns critical business operations into production-ready AI workflows in days, not quarters. Built by the former Noname Security team, the company packages agent orchestration, a knowledge fabric, data connectivity and modular building blocks into a single OS for production AI - and bills only for outcomes that ship.
