Funding and Acquisitions Roundup: TrapIt gets $6.2 million to bring AI to web browsing; Piazza gets $6 million to enhance the college class experience

Today’s technology funding and acquisitions news roundup…

Since the launch of Apple’s Siri virtual assistant, AI apps have garnered a lot of attention…and funding. That list now includes Trapit, an AI-based personalized search and web organizing tool, which announced today that it has raised $6.2 million in Series A funding. Both Siri and Trapit originated from the same AI collaboration between DARPA and SRI. The project was originally known as CALO—“Cognitive Assistant that Learns and Organizes”—and looks like it could be the next step in the evolution of search and web browsing.

Moving from artificial intelligence to human intelligence, Piazza—a social network meant to connect college professors and instructors with their students—has raised $6 million in Series A funding. Social apps for college classes has been a hot sector lately, with funding announcements recently from a number of companies doing similar things. Palo Alto-based Piazza’s round was led by Bessemer Venture Partners.
