AMBQ

Ambiq Micro, Inc.

A maker of ultra-low-power microchips that keep battery-powered gadgets alive far longer, Ambiq designs the Apollo system-on-chip family found inside wearable health trackers like the Fitbit Charge 6, plus software for on-device artificial intelligence. Born in 2010 from University of Michigan research into "subthreshold" computing, it was first incorporated as Cubiq Microchip before being renamed Ambiq in 2012. Its SPOT technology lets chips run at voltages so low that conventional designs fail, a trick the founders turned into a business after watching the industry wrestle with battery life anxiety.
