Building a Better Mouse Cage

A startup aims to take humans out of labs that test drugs on mice.

Instead of humans, Vium uses tiny sensors and high-definition cameras to observe lab mice.

Much of the groundwork for important new drugs starts with tests conducted on lab mice, of which there are an estimated 100 million around the world. The Ph.D.s and technicians who observe them often spend their time on rote tasks that a Silicon Valley startup called Vium wants to automate.

Co-founders Timothy Robertson, a physicist, and Joe Betts-Lacroix, an inventor who has sold inventions to Google, started Vium in 2013 with a mission to update mouse labs using cheap sensors, deep learning software, and virtually no humans. “We derived more data and better-quality data without exposing the mice to the stress of human contact,” says Robertson, who is also chief executive officer.
