This week, Kleiner Perkins partner Matt Murphy joined us in the TechCrunch TV studio for our Ask A VC series. As we discussed on the show, Kleiner Perkins has been making a solid bet on mobile for the past few years. In fact, we’ve confirmed with the firm that it has put more than $450 million in 40 mobile companies.

As Murphy explains, these investments include both the $200 million iFund (launched in 2008) and separate investments. So now the $450 million in mobile investments are part of the firm’s digital investing in both consumer and enterprise companies.

For background, the iFund was initially a $100 million collaborative initiative with Apple that focuses on funding and building applications on the iOS platform and the mobile Internet. The company doubled this to $200 million within a few years. But Kleiner has expanded the mobile focus to include enterprise, as well.

And Kleiner has built a pretty impressive collection of consumer-focused mobile investments including Shopkick, Path, Spotify, Pinger and Square. Of late, the focus has expanded to enterprise with companies like Apperian, Crittercism and Egnyte.
