12 of the most exciting tech companies in Cambridge

Cambridge is emerging as one of the top cities for tech companies in the UK, thanks to its world-class science and innovation.

With London having the highest level of start-up failures in the UK, (only half of start-ups were still in business three years after they were formed), you’d be forgiven for thinking about moving your operations elsewhere.

Cambridge may be that option if you run or manage a tech company. Dubbed Silicon Fen, Cambridge’s answer to California’s Silicon Valley, the city has many innovative tech companies headquartered here.

Founder of Cambridge firm GeoSpock Steve Marsh said, ‘The Silicon Valley gap is that their technology is pretty average, but the marketing is incredible,’ he says ‘In Cambridge we have rock solid technology, but we’re not so good at marketing.’

According to a 2018 Tech Nation report, Cambridge had double the digital tech turnover per staff (£152,000 each) compared to the average UK average of £99,000. Drawn here by its ties to the world-famous university and a good network of angel investors, tech companies are on the rise in the region.

Tech giants Apple have an AI outpost, while Microsoft set up a major research lab and Amazon used the city to test out Prime Air. Also, according to a recent report from Solopress, Cambridge was the third best place to start a business in the UK – behind Aberdeeen and Leicester, suprisingly.

Following this report, here are 11 of the best tech companies in Cambridge.
