AI has unlocked a step change in what’s possible in this market — and in how Baton operates.
Our goal isn’t to bolt AI onto existing workflows or launch a chatbot; it’s to re-architect how the product works, how internal operations run, and how value compounds across the platform.
Engineers here use AI as a force multiplier in their own work and in what they ship — and we take the craft of production AI seriously.

We build agentic systems that handle real customer interactions and business workflows end-to-end.
Expect to work across the full loop — from problem framing → data → evals → iteration → deployment → monitoring → continuous improvement; grounded in measurable outcomes (quality, latency, cost, reliability).
We care about shipping quickly and building systems that hold up in the real world.
We build in person in NYC because this work moves faster and gets better when the team is in the room together.
We value low ego, high respect, direct communication, and real ownership.

Mission-driven work: empowering entrepreneurs and shaping the future of small business transitions.
A collaborative, data-driven, and growth-oriented culture.
An opportunity to make a significant impact at an early stage in our journey.

We believe that democratizing access to small business ownership with reliable data and tools for buying and selling businesses will reshape the economy.
At Baton, we’re building the AI-native platform that makes small business transitions transparent, fast, and fair as we support the millions of baby boomers who have poured their life into their small business.
We’re already the largest marketplace in the space with nearly 100 closed transactions & thousands of listings in front of tens of thousands of active buyers on the platform.
