About Ambiq Micro, Inc.
Ambiq® was founded in 2010 on the simple yet powerful notion that extremely low-power semiconductors are the key to the future of electronics. Through the use of pioneering ultra-low power technology, innovative companies around the world are developing differentiated solutions that reduce or eliminate the need for batteries, reduce overall system power and maximize industrial design flexibility. Our mission is to enable intelligence (artificial intelligence (AI) and beyond) everywhere by delivering the lowest power semiconductor solutions. We enable our customers to deliver artificial intelligence compute at the edge where power consumption challenges are the most profound. Our technology innovations, built on the patented and proprietary subthreshold power optimized technology (SPOT), fundamentally deliver a multi-fold improvement in power consumption over traditional semiconductor designs. We’ve powered over 270 million devices today. As we see the shift in devices move from “smart” to “AI,” our technology and solutions have evolved to accommodate the power requirements needed to enable feature rich devices that are always on, high performing, secure, accurate, energy efficient, and just as important practical. Our leadership in powering devices made for edge AI has helped technology innovators across wearable, smart home and buildings, industrial, healthcare, and other sectors deliver intelligent devices that can do more while consuming less.
