Head of Revenue

TL;DR: We're looking for the person who will build White Circle's revenue engine. Today, most of our commercial motion is founder-led. We have customers, growing demand, strong investor backing, and a market that is rapidly realising AI systems need safety, evaluation, and governance layers. What we don't have yet is a repeatable machine. Your job is to create it. You'll work directly with the CEO to turn early traction into a scalable go-to-market organisation. You'll own enterprise sales, help define positioning, build forecasting and pipeline discipline, shape pricing and packaging, and eventually hire the team around you. About us White Circle is an AI Safety company building the safety, reliability, and optimization layer for AI systems. At the core of our platform are policies – simple natural-language rules that define what an AI model should and shouldn’t do. We automatically test, enforce, and continuously improve these policies at scale. We’ve raised $11M from top funds, founders, and senior leaders at OpenAI, Anthropic, HuggingFace, Mistral, DeepMind, Datadog, Sentry, and others We process over one hundred million API calls every month We fine-tune and train our own LLMs so they run faster and cheaper than any open or proprietary model We’re a small, highly focused team.
