The Cambridge Computer Lab Ring1 is a members' association for staff and graduates of the Cambridge University Computer Laboratory. It was formed in 20022 by Stephen Allott3 as a non-profit, independent and voluntary members’ association, and was absorbed into the Cambridge University Computer Laboratory in 2012.4 It was named by Sir Maurice Wilkes after the Cambridge Ring.5
The association was mentioned by Richard Lambert in the Lambert Review of Business-University Collaboration as an example of how "universities, departments and faculties should develop their alumni networks in order to build closer relationships with their graduates working in the business community."6
Notable companies formed by members of the Cambridge Computer Lab Ring include ARM, DeepMind Technologies and Raspberry Pi.7
Formation
Founded in 1937 as the Mathematical Laboratory, the Cambridge Computer Laboratory was at the forefront of the development of computing through the twentieth century.8 This included the introduction of the world's first full-year taught course in computer science, the Cambridge Diploma in Computer Science.9
With several alumni going on to found successful technology companies, notably in computer software, several University of Cambridge alumni and staff saw benefit in forming a network that would allow graduates to get "a lifetime benefit from their Cambridge degrees, professionally, technically and socially."[1]
To this end Head of the Computer Laboratory Professor Ian Leslie directed Stephen Allott, a Cambridge graduate who had recently scaled software provider Micromuse to $7.8 billion following its floatation on the Nasdaq,10 to form an alumni association. This led to the introduction of a programme of events to promote "intellectual rigour" and to connect alumni.[2]
Hall of Fame
The association claims that, as of May 2026, there are 371 companies created by computer lab graduates and staff.11 A 'Company of the Year' is chosen from this list annually.12
