Heart Capital-Backed AI Semiconductor Maker Ambiq Lists on NYSE | Heart News

On July 30, 2025, Ambiq Micro (ticker: AMBQ), an edge AI chip company in Heart Capital's portfolio, successfully listed on the New York Stock Exchange. The stock opened at $38 on its first trading day, well above the IPO price of $24. Trading was temporarily halted mid-session due to excessive volatility after the stock surged 74.17%. The company closed with a market cap of $660 million. As a leader in ultra-low-power semiconductors, its debut signals accelerating momentum in the edge AI chip sector.

Yan Han, Founding Partner of Heart Capital, extended his sincere congratulations to Ambiq Micro. "Congratulations to Ambiq on its successful NYSE listing. This is a highly globalized team, and their edge AI ultra-low-power chips have made their way into many of the world's most famous consumer electronics brands, injecting AI vitality into their products," said Han. "As AI continues to evolve, we expect their edge chips to play an even bigger role. The Heart Capital team will keep a close eye on early-stage opportunities in AI chips, hardware, and applications."

Founded in 2010, Ambiq Micro is a pioneer and leading supplier of ultra-low-power semiconductor solutions designed to address the enormous power consumption challenges facing general-purpose and AI computing, particularly in edge computing environments. Ambiq Micro's customers rely on the company to bring AI computing closer to end users — at the edge — where power constraints are most severe. The company's position rests on hardware and software innovations that reduce power consumption by 2 to 5 times compared to traditional semiconductor designs.

The company's self-developed SPOT (Subthreshold Power Optimized Technology) is its core moat, capable of reducing chip power consumption by more than 5 times. As of 2024, Ambiq had shipped over 270 million SPOT chips cumulatively, with more than 40% running AI algorithms. These chips have been deployed in well-known devices such as Samsung Galaxy Watch and Fitbit, giving Ambiq a leading market share in smart wearables and industrial IoT. The company continues to drive AI application development at the edge across personal devices, digital health, industrial edge computing, and smart home and building automation. Ambiq Micro's solutions include a rich portfolio of system-on-chip (SoC) products and the software required to enable on-chip AI processing, general-purpose computing, sensing, security, storage, wireless connectivity, and advanced graphics. Its SoCs deliver significantly lower computing power consumption than competing products. Ambiq Micro's ultra-low-power SoCs serve numerous markets requiring on-device and real-time AI, including smartwatches and fitness trackers, augmented and virtual reality (AR/VR) glasses, smart rings, digital health monitors, security systems and access control, livestock tracking, crop monitoring, and factory automation. These devices increasingly offer on-chip AI-driven capabilities such as voice recognition, domain-specific language models, image and video processing, and sensing.

Ambiq Micro's listing today marks another bell-ringing moment for Heart Capital, and the 15th IPO for the firm's investment team. As an early-stage venture capital fund rooted in China, Heart Capital's investment team averages over ten years of investment experience and has long focused on strategic deployment across new energy, new transportation, and digitalization — including Series A investments in Xpeng Motors (NYSE: XPEV, HKEX: 09868) and Full Truck Alliance (NYSE: YMM), a Series B investment in FinVolution (NYSE: FINV), and an angel-round investment in Quantum Song (NASDAQ: QSC).

Heart Capital was founded in 2022 by Yan Han, formerly a founding partner at Lightspeed China, as a China-based venture capital fund focused on early-stage technology and digitalization.

The Heart Capital team is composed mainly of founding partners, the CFO, and core investors from Lightspeed China, alongside seasoned industry investors from Cainiao and Baidu. The team's past investments include Series A rounds in Full Truck Alliance (NYSE: YMM) and Xpeng Motors (NYSE: XPEV, HKEX: 09868), as well as FinVolution (NYSE: FINV), 06810.HK, RoboSense, World Logistics, LandSpace, Lanhu, MinoSpace, and Starfield, among others.

Rooted in China with a global outlook, Heart Capital is dedicated to finding world-changing leaders of tomorrow. The firm champions the value of "people" and "heart," and looks forward to accompanying more young Chinese entrepreneurs onto the world stage.
