Angela McNeal Is Building for AI’s Messy Middle
After a decade putting machine learning to work inside complex institutions, the Thread AI co-founder has a clear thesis: the clever model is only the beginning. The consequential work is making it useful, governed and dependable.
Thread AI
Thread AI is a New York enterprise software company building composable infrastructure for AI-powered workflows. Founded in 2023 by former Palantir AI/ML leaders Angela McNeal and Mayada Gonimah, its flagship platform Lemma pairs a drag-and-drop workflow builder with orchestration infrastructure so organizations can connect disparate systems, data, and AI models into governed, observable, end-to-end workflows - without ripping out their existing stack. The company raised a $20M Series A in 2025 to help enterprises and public-sector agencies deploy mission-critical AI with control, traceability, and security.
