A private AI business platform is a system built for one company that connects its existing tools — CRM, accounting, email, documents, phones — into a single owned database with an AI assistant on top. Instead of staff asking a public chatbot questions it can't answer, they ask an assistant that can see the live business: who owes what, which project is over budget, what was promised on last week's call. Reasonwave calls this a business brain.
Those are general assistants that see what you paste or what sits in your Office files; a Reasonwave platform is built around your actual data model and runs on infrastructure you control. It can take actions, not just answer — raise an invoice, update a record, draft a board pack from live numbers. You own it outright, rather than renting seats. We've written a fuller comparison with Microsoft Copilot.
Every platform is scoped to the business, so we price per project after a discovery call rather than from a rate card. Most clients fund it from the software subscriptions they cancel and the admin time they get back. We'll give you a fixed price for a defined first phase before any work starts.
A first working version is typically live in weeks, not months. We build in phases: core data and integrations first, then the modules you need, then the AI assistant on top. You see working software early and steer from there.
On private UK infrastructure at Equinix Slough, with replication to a second UK data centre. Sensitive data is processed on that infrastructure. Which AI models run where — local or external — is agreed with each customer up front and documented.
No. Your data is never used to train any model, ours or anyone else's. Where an external model is used for a specific task, it's used under terms that exclude training, and only for data you've agreed can go there.
You do — the code, the data and the configuration. If you ever leave, you take it with you. That's the point of building rather than renting.
Anything with an API or an export — if your data is in it, we can connect it. We work with Xero, Sage, QuickBooks, Podio, HubSpot, Salesforce, Procore, Microsoft 365, Google Workspace, Zoho, GoCardless, Stripe and standard phone systems, and connecting a new one is routine, not a project.
No. The platform sits on top of what you already run and gives you one place to see and act on it. Over time most clients retire tools they no longer need, but that's their choice, not a requirement.
UK businesses that run on data and are tired of it being scattered across six systems. We build for owner-managed firms through to mid-sized companies, in construction, professional services, hospitality, manufacturing and other sectors that run on data. If you can describe how your business actually runs, we can build the brain for it.
Reasonwave is in Coventry, with a London office for meetings. Everything is designed, built and supported in the UK by our own engineers — no offshore handoffs.
A 30 minute call. No deck, no pressure, no junior sales rep. You talk, we listen, and you leave with a straight answer on whether a brain makes sense for your business.
