Our Connected Scheduling platform gives you a staff bank, rota tool and a clinician network all in one place to improve fill rates, cut admin time, and reduce costs.

Melissa knew that by using technology to break down the barriers between practice managers who need to fill vacant sessions and GPs looking for a more flexible way of working, patients would see an increase in the quality of care they were receiving. We’re a small, but rapidly growing, team based in the heart of London’s start-up scene.
