Nothing happens by chance.

As many of you know, this week we’re running our Artificial Intelligence series, a collection of stories focusing on the Boston AI ecosystem. On Wednesday, MIT announced the winner of the $100K Entrepreneurship Competition — an annual contest that gives away $100,000 to the grand prize winner.

And the winner turned out to be an AI startup: Lightmatter, which is using light to accelerate artificial intelligence.

This year, the Institute received 160 applications that went down to 50 semi-finalists. Two weeks ago, the semi-finalists pitched their ideas behind closed doors and were narrowed down to eight finalists. On Wednesday, the final eight ventures pitched in front of the judges — Caroline Brown, Edward Ahn, Erik Norlander and Mira Wilczek — and the public.

Here’s the list of the eight startups that competed in the MIT $100K Launch Finale (descriptions courtesy of MIT’s blog):

Lightmatter – Winner

This team of four – Nick Harris, Darius, Yichen Shen and Thomas Graham – is working on new kind of artificial intelligence hardware that is powered by light, rather than electrical signals. The final goal of the company is replacing transistors with Lightmatter’s systems, which are able to calculate faster and more efficiently than existing artificial intelligence hardware.
