Ways to work with Silex
Are you running a business, or building for one?
Pick your side and we'll show you the part that matters to you.
Own the platform your business runs on
You get a platform built around how your business actually works, not a subscription you rent forever. Code, data and infrastructure stay yours, and we stay on to run it.
- Built for your operation: pricing, accounts, stock, bookings.
- No per-seat or per-property fees, and no lock-in.
- A team that stays for years, not until launch day.
Deliver under your own brand
Agencies that sell but don't build, and IT firms that need the software layer. We build and run it behind your name, and your client never deals with us. 18 years doing exactly this.
- White-label delivery. Your brand, your client relationship.
- A senior team on demand, without the hiring cycle.
- We hold the platform long after handover.
How we partner
A low-risk first step, then a platform you own.

A short call and a written summary of what to fix and what it's worth - no obligation.
Build - you own it
We build to fit your business. Code, data and hosting are yours outright.
Run & support for years
