About Mem0

Mem0 enables AI agents & apps to continuously learn from past user interactions, enhancing their intelligence and personalization. Backed by Peak XV and Y Combinator.

Every AI agent today forgets you the moment the session ends. We're fixing that, and you'd be one of the people building the models that decide what an AI remembers, forgets, and learns over time. This isn't research bolted onto a product team: you'll take an idea from a paper on Monday to an A/B test in production within weeks, with millions of real interactions to learn from. If you want your fine-tuning runs to ship, not sit in a notebook, this is that role.

You'll own memory features end-to-end: fine-tune models for extraction, updates, consolidation/forgetting, and dreaming; turn real customer pain points into research hypotheses; implement...
