About us

Welcome to

Formed in 2009 by Sarah Treanor & Mark Thurman at the height of the financial crash, a time when employment felt particularly perilous.

Based in Leicester and Hereford we service customers across the entire UK and beyond.

Enterprise skills - available to all

Before founding Credible Systems, Sarah and Mark had many years of experience delivering large scale technology projects for clients across Europe. Bringing this experience and maturity to clients of all sizes is in everything we do.

Success Driven

We pride ourselves on our flexibility and willingness to make your projects a success for you. We know our clients are particular about who they partner with and so are we. We seek long term relationships where possible.

Happy people!

It may sound trite, but we enjoy working with people we like.

Indeed, our mantra is one of "if you can pick who you work with, why not work with people you like and who like you?"

All Stars

The Team

We are spread across 2 teams, the Design & Development Team and the Projects Team.

Normal rules apply.

Approach with caution, bearing pizza. Do not feed after midnight.

Away from his desk, he can often be found playing with swords, twirling his moustache and sipping fine rum. Though rarely at the same time.
