Our Story

High Performance Wizards

Our founders have known each other since they were both at Cambridge University. Their first jobs were at a subsidiary of British Telecom writing software for dealing turrets, which in those days meant squeezing every last ounce of performance from a microprocessor or data link.

Chris moved onto the emerging industry of digital voice recording, where be became CTO of Eyretel through its IPO. Richard stayed close to dealing rooms, specialising in high speed market data at several Wall St companies.

After they joined forces again at Eyretel, they revelled in building one of the first software-only voice recorders, using Avaya's brand new DMCC softphone API. Their combined experience in high performance systems allows the recorder to record and compress thousands of channels on off-the-shelf servers.

Seasoned Firefighters

We are experienced troubleshooters used to working with large, complex, high-speed systems - and with large, complex, irate customers.
