Stop renting software. Own it.

Per-seat subscriptions look small each month until you multiply them across tools, seats and years. We replace them with software you own: open source where it exists, custom where it matters, all on a server in your name.

How it works

Tell us what you run. We call back within one working day.

Four fields, no account, no newsletter. A person from the team reads it and replies on WhatsApp with a straight answer: what we would do first, roughly what it costs, or “not yet”.

  • A reply within one working day, on WhatsApp or a call
  • Your details go into our own CRM and to the team's phone, nowhere else
  • No drip emails, no follow-up bots

Goes straight to our CRM and the team's phone. Nothing is shared or sold.

Questions owners ask
Is open source safe for a business?

The tools we deploy run thousands of companies. We add backups, updates, monitoring and access control, and you can audit all of it.

Will my team have to relearn everything?

We mirror the screens they know where it helps and train them on what changed. The old tool stays live until sign-off.

What about updates and security?

Covered under a monthly support plan, or handed to your IT with runbooks.
