About Us

Our mission? Creating equal access to coaching at work. 

How we make it happen? Our AI coaching platform replicates the coaching of 9 of the world’s top experts. Forget ChatGPT wrappers, AI chatbots, or clunky 3D avatars. Our multimodal platform is fuelled by the top 0.1% experts, and includes real-time advice features bringing insights from world-class coaches into the flow of work.

Our latest obsession: providing every manager with expert insights, when they need it… and without asking for it! We have recently raised capital to make this become a reality.

We’re early, we’re ambitious, and we’re doing something that hasn’t been done before. The kind of thing that’s equal parts exciting and terrifying — in a good way.
