Canvas is a Y Combinator-backed company focused on AI systems that get better through experience. Its main product, Canvas Coworker, takes on extended go-to-market and knowledge-work assignments rather than one-off prompts.
The key idea is that the coworker adjusts based on the feedback you give it, so results should improve the more your team uses it. Canvas also publishes open research on agents and continual learning. It is a paid product aimed at business teams.
