This article highlights three such AI small caps from our screener worth a closer look.

The three stocks below are just a starting sample from this theme. The full screen surfaced nine more AI small caps with equally compelling narratives that are not covered here.

To go deeper into this corner of the market, head straight into the AI Small Caps screener to identify ideas, compare fundamentals, and analyze which AI small caps best fit your own conviction.

Finatext Holdings (TSE:4419)

Finatext Holdings builds cloud-based financial infrastructure, smartphone trading apps, and AI powered data and analytics for banks, brokers, and real estate clients. It generates about ¥1,611 million from fintech shift services, ¥3,205 million from big data analysis, and ¥6,976 million from financial infrastructure, with a market value near ¥68.1 billion.

Finatext Holdings gives you access to AI driven analytics sitting inside real money workflows across finance and property, not just lab experiments. The company currently trades on a premium P/E, and its valuation and funding structure depend heavily on how cost pressures and other business dynamics ultimately affect profitability.

That funding question is exactly why the Finatext Holdings financial health report could matter most for Finatext Holdings, before valuation headlines drown out balance sheet realities.

Fixstars (TSE:3687)

Fixstars builds high performance software and hardware, including GPU acceleration, quantum computing tools, and AI solutions. Its AI link to this screener runs through Fixstars AIBooster, a GPU cloud for generative AI and large language models. Most revenue comes from the Solution Business at about ¥9,863 million, with SaaS contributing roughly ¥856 million, and the group is valued near ¥57.1 billion.

Fixstars taps the AI Small Caps theme through AIBooster, giving developers GPU cloud access for generative AI and large language models rather than just selling generic software projects. The business has a premium P/E around 35x versus Japanese software peers near 18x and recent results show revenue at ¥7,917.1 million with net income at ¥1,315.93 million. Your view may depend on how pressure on profitability develops over time.

That profitability pressure is exactly where the analysis report for Fixstars could help you judge whether Fixstars premium still matches its AI and GPU cloud ambitions.
