In June 2020, West Fountain Global Fund LP ("West Fountain"), an offshore parallel fund of West Fountain Parallel Fund, completed a new round of investment in Ambiq Micro, Inc ("Ambiq Micro"). Previously West Fountain participated in Ambiq Micro's Series D in June 2017, Series E in July 2018 and the last round of convertible debt financing in August 2019.

Ambiq Micro was founded in 2010 with the simple yet powerful philosophy that ultra-low power semiconductors are the key to the future of electronic products, through its proprietary Subthreshold Power-Optimized Technology (SPOT™) platform.

In March 2020, CEVA, Inc. (NASDAQ: CEVA) announced that Ambiq Micro, the leader of ultra-low power solutions, licensed RivieraWaves Bluetooth® low power IP for CEVA products using its next generation of Subthreshold Power-Optimized Technology (SPOT) platform integrated with Bluetooth connectivity. CEVA's Bluetooth low power (BLE) IP has provided power for Ambiq Micro's Apollo 3 blue series wireless system on chip. The chip is widely used in many applications that need intelligence, from wearable devices to animal trackers to smart home devices from the world's largest brands.

The Apollo3 Blue family of SoC solutions represents a giant leap forward in ultra-low power design. With unparalleled power figures in both active and sleep modes, coupled with a high-performance processing engine, Apollo3 Blue devices offer the most efficient processing solution on the market. In order to achieve connectivity, Apollo3 Blue products integrate energy-efficient Bluetooth 5 low energy radio and improved communication features, which can realize the ultra-low power design of always connected. The core of all Apollo 3 products is the patented sub threshold power optimization technology (SPOT™) of Ambiq Micro. SPOT significantly reduces energy consumption while still having enough application processing power to add functionality and extend the life of battery powered devices, including hearing devices, wearable devices, IOT endpoint devices, and voice control applications.

West Fountain Parallel Fund believes that the technical barriers to low-power chips are extremely high, Ambiq Micro has solved the bottleneck problem of chip performance and achieved the typical cost reduction and efficiency improvement. In terms of innovation ability, this team has the world's leading advantage.
