What Surface is
An AI GEO employee. It watches whether a brand is named when ChatGPT, Perplexity, Gemini, Claude and Google AI Overviews answer the questions its buyers actually ask, proposes the work that would change those answers, does that work once approved, and comes back with the before and after. One founder, a Delaware C corporation, pre-launch.
What you would own
The engine. Five owned direct-provider collectors, the scoring and aggregation that turn raw answers into a position, the propose-and-draft loop, and the evaluation harness that decides whether a new prompt version is allowed to ship. You would be the first engineer, which means you also own the parts nobody has written yet: the worker that moves the engine out of the request cycle, the per-tenant memory, and the cost ceilings that keep a paid run from outliving its budget.
What we look for
You have shipped something that calls model APIs in anger and survived contact with rate limits, partial failures and a bill. You write TypeScript you would be willing to leave untouched for eighteen months. You treat an eval set as the thing that decides, and a benchmark you cannot reproduce as noise. You have opinions about when an agent should ask and when it should act.
What we do not look for
Someone who wants a spec handed down. Writing the spec is half the job.
The honest part
There is no revenue yet. The product ships publicly in September 2026. The equity is real and it is early, and early equity is usually worth nothing. Come because the problem is good.
