Overview

Lunos is transforming the world of B2B payments with an AI partner that manages receivables like a human would—24/7, never forgetting, and reading every message sent to it.

We’re a small team with big ambitions, backed by top-tier VCs who were early backers of companies like Stripe and Airbnb. We’re building in a modern stack (TypeScript, Next.js, Vercel, Supabase/Postgres, Tailwind), blending agentic AI architectures, curated LLM pipelines, quantitative methods and robust SaaS foundations.
