Cary launched Mydeo in 2005 following a government research and development grant for technical innovation. She has since gone on to raise over £0.5 million in funding for her startup. Mydeo became the first and only service to be fully integrated into Microsoft’s Windows Movie Maker software. Mydeo now provides high-quality streaming video hosting to over 250,000 individuals, communities and businesses around the world. In October 2007 Mydeo announced that Best Buy, the largest consumer electronics retailer in the US with market value of over $20bn, was taking a minority equity stake in Mydeo, and would be using the Mydeo platform for its own bespoke video sharing service. Mydeo won a commendation in the Best Streaming Service category at the 2008 UK Internet Service Provider awards and was a Red Herring Europe 2008 finalist.
