We build electric motorcycles. Our bikes work well on their own today. We’re building a connected system across the bike, cloud, and field tools so we can see how they behave in the real world, understand what changes actually do, and use that to decide what’s worth building.

That means owning behavior end-to-end, from firmware on the bike to the systems that observe and update it, and making sure it is reliable and secure in the real world.

Octozi is a revenue-generating seed-stage company building AI agents for clinical development workflows. Bringing a drug to market can take a decade and cost up to $2B, keeping treatments expensive and delaying life-saving therapies for the patients who need them. We're cutting the cost and time of these workflows while improving the science and analysis of clinical data.

We already have commercial contracts with multiple pharma companies and are scaling the team to meet demand. The interesting problems span agent orchestration over messy clinical datasets, human-in-the-loop review at scale, and turning unstructured medical reasoning into auditable, regulator-ready output.

Looking for a full-stack engineer to join as a founding hire with startup experience strongly preferred. Stack: Python, TypeScript, AWS, PyTorch.

Hey, I'm one of Stellar's founders. We're building AI for large contact centers, our primary product is voice.

Contact centers are the last place where companies actually talk to their customers. We listen to calls every week and it's fascinating. AI here helps real people: shorter wait times, 24/7 support, lower cost. We’ve helped companies go from 60 to 98% pickup rate in weeks. We’ve had (human) agents asking us to accelerate our roll out plan because the days with Stellar are so much better than the days without.

We’re all builders. Everybody in our company still writes code. We have one role open:
