On Tuesday, Miner announced investments in two mobile companies: Astrid, which offers a task management application, and Crittercism, a software platform for support forums that mobile app developers can add to their applications. He did not disclose the size of the fund's investments. Astrid began on Android and on Tuesday launched an iOS version of its app.

Miner is now looking toward enterprise mobility, seeing a void in the market that BlackBerry devices filled during the age of feature phones. Unless there are big changes at RIM, he expects most current BlackBerry users to switch to another platform soon. RIM and recently reported declining BlackBerry sales.

"I've seen some enterprise applications, some of them decent, for mobile, on Android and for iOS, but not nearly enough," Miner said. "To me, that's a huge opportunity, since neither Apple nor Google are really focused on the enterprise that much."
