Paul Ashley set up Yellow Door Property Ltd in 1993, initially running it alongside his other business interests before growing it into his main business in 2012.

Paul draws his commercial expertise from a range of successful entrepreneurial and directorial posts over more than three decades. Prior to moving into full-time property development, he built a nationwide financial services brokerage and then became a board member of a group of IT companies developing community-based portals and business directories. That company was floated in 1998 and Paul went on to build an online data backup business providing secure, remote storage for large corporations.

More recently, he provided seed funding and initial chairmanship for a 'Big Data: Machine Learning' Internet start-up company focused on the music industry. Following its pioeneering technological breakthroughs, a major Silicon Valley firm acquired the company in 2014.
