History

The company was established at the University of Michigan by professors Dennis Sylvester and David Blaauw and postdoctoral researcher Scott Hanson, who serves as the chief technology officer. [1] Two MBA students, David Landman and Philip O’Niel, also contributed as co-founders. [2] Initially named Cubiq Microchip, Ambiq Micro spent several years developing its technology before creating its first commercially viable prototype. [2]

Early on, the company participated in several business plan competitions. In 2010, it received awards at the Michigan Business Challenge and the DFJ-Cisco Global Business Plan Competition. [3] It also secured pre-seed funding from the University of Michigan’s Frankel Commercialization Fund. [1]

In 2025, Ambiq Micro filed for an initial public offering on the New York Stock Exchange under the symbol AMBQ, with BofA Securities and UBS as lead underwriters. [4] The company sold four million shares at $24 each, raising $96 million, and ended its first trading day with a market capitalization of $656 million. [4]

Products and technology

Ambiq commercializes Subthreshold Power Optimized Technology (SPOT), a design method that operates transistors near or below their threshold voltage to reduce active and sleep-mode power consumption, [5] [6] thereby enabling on-device edge AI. [7] Its product line includes microcontrollers and systems-on-chip, called Apollo, [1] [8] as well as real-time clocks, called Artasie, [9] which are used in smartwatches, medical devices, and industrial and agricultural sensors. [4] [10]

The company primarily serves the wearable technology market. [4] Google, Garmin, and Huawei were its largest customers, together representing over 85% of pre-IPO revenue. [4] [7]
