A Cambridge health technology pioneer has opened a new UK office at the heart of London’s Silicon Roundabout as it ramps up headcount to meet global demand.

Cambridge Healthcare Ltd, whose How are you? eHealth portal promises to give patients more say in their treatment, has added the Tech City offices to its global headquarters in Cambridge and its Beijing operations.

Founder and CEO, Dawson King, says the London office will help the business attract new engineering and design talent from the Tech City hotspot.

The move comes just a week after the company signed an exclusive licensing agreement that will see its technology adopted by China’s largest consumer website and brand, Sina.com, with more than 500 million registered users – a third of China’s population.

In the last two months, Cambridge Healthcare has grown its head count from four to 13 people and is continuing to aggressively recruit both in Cambridge’s Silicon Fen and now London’s Silicon Roundabout.

In the UK and US, Cambridge Healthcare has been working closely with Microsoft Health on integrating the global giant’s HealthVault solution into How are you? (howareyou.com). An announcement detailing the partnership is expected later this week.

King said: “This is a very exciting time for us as we transition from start-up to enterprise. Growing from a few hundred thousand users in the UK to more than 500 million within a couple of months is not just an engineering challenge but also an operational and HR one. We’re facing similar growth to Facebook when it started.

“Our commitment to building an integrated care record is maturing as our health application platform starts to enable the integration of patient records with remote diagnostic and home healthcare devices; we have also now begun to develop applications focused at health professionals ready for our clinical portal launch in September.”

Cambridge Healthcare recently won the Institute of Engineering and Technology Innovation Award for best IT Technology and HealthInvestor Award for IT innovator of the year. Its technology is provided 100 per cent free to NHS patients and healthcare professionals in England.

Cambridge Healthcare is working in partnership with the NHS and Connecting for Health to develop the howareyou.com e-Health portal for patients and healthcare professionals. The portal will integrate with the NHS IT infrastructure and provide the platform for an unlimited number of healthcare applications.

As well as providing an electronic personal health plan for patients, the company is creating the first ever healthcare application store, encouraging third parties – including medical technology companies and healthcare providers – to design an unlimited range of innovative, useful and high-quality applications.
