Our team brings together deep technical expertise in AI with proven experience in enterprise software and procurement. We're backed by forward-thinking investors who understand the massive opportunity in applying advanced AI to high-value B2B negotiations. With several major enterprises joining us, we're positioned to become the category-defining platform for AI-powered procurement. We are founded and backed by Revolut and HSBC executives. We're a small, flat team that values simplicity, ownership, and shipping. We use AI tools aggressively — not as a novelty, but because they make us faster.

We're not just building software - we're creating the future of how businesses negotiate their most critical deals.
