About

Built on the round,
not in a boardroom

Extero started because the tools for window cleaners were either generic CRMs with cleaning bolted on, or spreadsheets and WhatsApp holding the whole business together.

We run an exterior cleaning business ourselves. That means Extero is shaped by real rounds, real invoices, real Direct Debit mandates and real evenings spent chasing paperwork.

The goal is simple: get you from enquiry to money in the bank without hopping between six apps and a notebook. Customers, jobs, routes, messaging, risk assessments, completion packages and payments live in one place — on your phone at the doorstep and on the web at the desk.

We are in private beta, inviting founding users a handful at a time so every new business gets set up properly. If that sounds like you, join the waitlist.
