Borchers has been with Apple since 2004 and is best known to most Apple followers as the individual who demonstrated many of the original iPhone features in a video filmed by Apple.
The former Apple exec told the Wall Street Journal that working at Apple was "Amazing" but that the venture capitalists at Opus offered him an opportunity to join and make investments in mobile technologies.
Opus is a firm with four current partners and more than $1 billion in committed assets. The Wall Street Journal reports that Opus raised $280 million in assets in its last fund; Bob Borchers will be investing from that fund.
