About Cellbyte

At Cellbyte, we’re building an AI-native platform to help pharma companies launch new drugs worldwide. Cellbyte empowers pharma commercial teams to cut through complexity, analyze previously fragmented data in seconds, and automate high-stakes workflows.

In just a few months, we’ve gone from early pilots to being trusted by global pharma leaders, closing enterprise deals, and scaling profitably with double-digit month-over-month growth. We build fast and iterate closely with customers to make something people want.

You’ll be joining a fast-growing startup at the exciting intersection of AI and Life Sciences. We're backed by Y Combinator, and have recently raised a Seed round from top-tier investors to fuel our next phase of global expansion. Life is too short not to build something truly impactful, so join us on our mission to accelerate access to life-saving medicines.
