At Catapult, we're building AI systems that securely understand you, your work, and its full context. We call this Contextual Intelligence—the essential layer needed to build truly useful, reliable, and autonomous AI.
With this, Catapult will help you:
We're solving foundational problems that Apple Intelligence, Gemini, and others haven't cracked yet. Our approach combines building cutting-edge systems for ingesting and understanding data with our powerful multi-stage reasoning models.
Our early results are promising, we're well-funded, and we're building a team of brilliant minds—sharp problem solvers, researchers, and engineers who thrive on tackling novel challenges in a dynamic, highly technical environment.
If you truly want to do the best work of your career, join us. You'll work directly with Catapult's co-founders—Rav, a 2x startup founder and former EMEA Lead at Meta, and Greg, a former Cambridge researcher who taught mathematics, statistics, theoretical CS, and AI.
