AI related goods are now a major engine of global trade, with DHL expecting technology driven shipments to grow through 2029. That rising tide does not only matter for chip giants. Smaller US companies building the tools, software, and infrastructure behind this boom can also benefit as demand filters through supply chains. This article highlights three AI focused small caps from our screener that investors may want on their radar.
The three tickers in this article are only a first look, with the wider screen surfacing 35 more AI focused small caps with narratives that are just as compelling but not covered below. To size up the full field and identify which early stage players best fit your own thesis, head straight into the AI Small Caps screener.
Braze (BRZE)
Overview: Braze runs a customer engagement platform that uses AI driven tools to help brands send personalized, data informed messages across channels.
Operations: Braze generates about US$834 million from its customer engagement platform, with roughly US$460 million from the United States and US$375 million internationally.
Market Cap: US$3.0b
Braze matters for this AI Small Caps theme because its machine learning tools are wired directly into how brands talk to their customers every day.
"Braze's acquisition of OfferFit is expected to enhance AI-driven optimization capabilities and lead to revenue growth through deal size expansion and differentiation in the market."
What really moves the needle from here is how one quiet shift in customer adoption shapes future margins and top line momentum.
If that adoption shift matters to your thesis, read the full narrative for Braze to see how Braze’s AI engine could reshape customer economics and competitive positioning.
HeartFlow (HTFL)
Overview: HeartFlow uses AI and computational modeling on coronary CT scans to deliver non invasive 3D heart assessments for coronary artery disease.
Operations: HeartFlow generates about US$212 million from non invasive coronary artery disease detection solutions, with roughly US$198 million from the United States and US$14 million internationally.
Market Cap: US$4.4b
HeartFlow plugs directly into the AI Small Caps theme because its algorithms are not just back office tools but sit inside everyday cardiology decision making, turning routine scans into data rich guidance for treatment.
"The transition of HeartFlow Plaque Analysis to a Category 1 CPT code in 2026, with defined Medicare payment rates in both clinic and hospital settings and commercial coverage already at 57% of U.S. lives, sets up a path for more routine clinical use that can add a new revenue stream and support gross margin mix over time."
What really matters now is how one unresolved question about future adoption shapes the balance between rapid top line growth and eventual profitability.
That adoption swing is the hinge. Read the full narrative for HeartFlow for how HeartFlow’s CPT shift, payer mix, and capital needs could reshape the story from here.
SoundHound AI (SOUN)
Overview: SoundHound AI builds independent voice and generative AI assistants that power conversational experiences in cars, devices, and customer service channels worldwide.
Operations: SoundHound AI generates about US$203 million from internet software and services, with roughly US$136 million from the United States and US$46 million from other regions.
Market Cap: US$2.5b
SoundHound AI matters for this AI Small Caps theme because its voice and chat platforms plug directly into how drivers, diners, and customers interact with connected devices every day.
"Accelerating global adoption of voice-enabled and AI-powered interfaces across new and existing verticals, including automotive, enterprise, restaurants, and healthcare, continues to drive expansion of SoundHound AI's addressable market, supporting sustained double- and triple-digit year-over-year revenue growth and improved customer diversification."
What really shapes the payoff from here is how one pressure on turning that usage into consistent, profitable cash generation ultimately resolves.
That tension is exactly why it is worth reading the full narrative for SoundHound AI to see how SoundHound AI’s pipeline, contracts, and cash runway really line up.
