About

Flourish is a New York-based AI company developing energy-efficient artificial intelligence systems inspired by neuroscience and connectomics research 12. The company brings together AI researchers and neuroscientists to study connectomics — the mapping of neural connections in the brain — with the goal of inspiring AI architectures that require dramatically less power than today’s large language models 13.

Flourish was co-founded in 2025 by Thomas Reardon, a neuroscientist who previously led development of Internet Explorer at Microsoft and co-founded brain-computer interface company CTRL-Labs (acquired by Meta in 2019), and Rob Williams, a former Amazon executive 13. The company is pre-product and focused on foundational research 1.
