Battery Ventures has lured away Adrian Cockcroft, the engineer who remade Netflixs streaming-entertainment service, to become the venture-capital firms first technology fellow. Cockcroft will help Battery advise and evaluate companies and formulate investment theses, said Mike Dauber, a principal at Battery, in a blog post on Tuesday. While Cockcroft will play a role in sourcing deals, he wont be a partner. In his own blog post, Cockcroft said he would counsel large enterprise companies who want to work more in the cloud– using remote computers that work over the Internet rather than proprietary centralized computers.
