Y Combinator-backed Knowmia grows its library of educational video classes

Inspired by Khan Academy, the next wave of education technology startups are seeing opportunity in video.

At Y Combinator’s Demo Day today, two of the most seasoned entrepreneurs who presented were Ariel Braunstein, a member of the founding team behind Flip video cameras, and Scott Kabat, a marketing executive. “Video will do well in education,” Braunstein explained to the crowd of investors. “We can build a business out of it.”

Their new project, Knowmia, lets students watch thousands of educational videos to supplement traditional learning in the classroom.

We covered the company’s launch last week. Read more about Knowmia, a crowdsourced education service.

Knowmia is taking a page out of Khan Academy’s book by offering video lectures, but embraces a more diverse range of subjects. Featured lessons on the website’s homepage include a run-down of the electoral college system and the basics of micro-evolution. Similar to Codecademy and Hacker School, Knowmia encourages its users to develop skills in mobile design, programming, and web development.

The site launched last week, and Braunstein reeled off some impressive figures to demonstrate signs of traction: The site has a growing library of 7,000 lessons from 900 teachers. At this early stage, Knowmia is experiencing 26 percent growth week over week.

Knowmia is geared toward high school kids, but Kabat told me at Demo Day that they plan to expand to K-12 education.
