Hey Product Hunt, I'm Merlin, co-founder of Rex.
Lewis and I spent four years building AR software at Sequence. What we kept seeing: someone on the finance team copying data from a portal into a spreadsheet into NetSuite, every single day. Automation tools never fixed it because the work is full of exceptions and judgment calls.
So we built Rex to just do the work. Agents plug into your existing stack and run collections, portal uploads, and the AR inbox end to end. Anything sensitive gets routed to your team. Synthesia runs their AR on us today.
Ask me anything, including what the agents still get wrong.
