The next generation
of virtual assistants

Twenty Billion Neurons (TwentyBN) is a Microsoft M12-backed artificial intelligence startup committed to making personalized coaching and companionship accessible to all people.

Powering this mission is our expertise in computer vision, natural language processing and transfer learning. We create sociable AI assistants that understand human behavior with our end-to-end Human-Centric AI platform, which includes our crowd-acting data platform, deep neural network training and optimization, and the development of consumer applications.

After starting in 2015, we began providing cutting edge computer vision solutions to the world’s leading enterprises for automotive and smart home use cases. We also developed an avatar for live brick-and-mortar retail interactions. Today, we are using our technology to power consumer products.

Fitness Ally is TwentyBN’s first consumer product. The mobile app offers users on-demand, guided and entertaining workouts with live form feedback from a virtual trainer that sees, listens, and understands.

TwentyBN is a CB Insights 2019 Top 100 AI startup and a 2018 Gartner Cool Vendor in AI Core Technologies. Our founders have 30 years of combined experience in deep learning and software development. Yoshua Bengio, the Turing Award recipient in 2018, is TwentyBN's founding advisor.
