# Our Story

Frustrated by poor experiences with traditional agencies, our founders (just two regular candidates), decided that the outdated industry needed modernising and a new balance of power. In 2005, a new kind of agency model was born, putting the client and candidate at the heart of the experience whilst removing the pushy sales, schmooze and high fees.

# What makes us different?

Aside from a sensible fee model, custom technology and a direct unhindered path to candidates we…

…don’t sell candidates and we don’t sell jobs: we facilitate relationships and champion the process of ‘organic hiring’ to help create stronger and longer-lasting engagements.

# Who we work with

With an industry reputation for delivering results we are the go-to talent finders for tech start-ups to global brands who all demand the best service and talent.
