Rex 做什么

Rex is an AI-native service for order to cash. Rex replace manual operations with AI agents that continuously manage invoices, customers and exceptions. Order to cash is a $60B outsourced function because the work is too messy for traditional automation. Every customer has different context, exceptions do not follow clean rules, and the next step is often buried in emails, portals, handoffs, or someone’s memory. Rex agents run continuously in the background and resolve work to SLA standards so cash keeps moving. We're live with pre-IPO tech companies, managing >$500m in receivables from F100 companies, cutting manual follow-up cycles from weeks to hours. We founded Rex after spending four years building Sequence, an a16z-backed finance ops platform, from zero to Series A - where we saw firsthand that at-scale, O2C still runs on manual labour. Rex is the #1 winner of the Vercel AI Accelerator out of 2,500 teams, selected by Guillermo Rauch and leaders from OpenAI, Anthropic, Browserbase and more.

Describe what your company does in 50 characters or less.

AI Operations Partner for Enterprise Order to Cash

What is your company going to make? Please describe your product and what it does or will do.

We built an AI-native service that continuously manages the order to cash process for enterprises. Rex agents handle invoices, customer communication, and exceptions in the background, reducing manual follow-up from weeks to hours. This replaces manual, people-heavy operations in a $60B market that traditional automation can't handle due to messy, exception-heavy workflows.

Where do you live now, and where would the company be based after YC?

We live in London, United Kingdom, and plan to keep the company based here after YC.

Explain your decision regarding location.

We're based in London because that's where we started building Rex and where our early users are. It makes sense to stay close to our customers and continue building here rather than relocate after YC.
