I have worked with Chris on a few occasions, beginning at Razorfish, and as both a colleague and then client at Bio then Nimbletank. He is one of a rare-breed of strong business-minded CTOs in London, who is able to strategically help businesses from start-ups to multi-nationals. He is a passionate exponent of mobile and digital transformation and someone very highly regarded in the industry, and also a very nice person to work with. I highly recommend his services.
