3 Obscure Small-Caps to Watch as Sleep Tech and AI Infra Heat Up

Everyone is piling into the same ten names. Dell is printing 100% AI revenue growth, Palo Alto just doubled its platform additions, and the CNBC chyron has basically become a Nvidia fan account. Meanwhile, a few genuinely obscure companies are quietly doing something worth your attention, and nobody on X is yelling about them yet.

$HCKT (The Hackett Group) is a Miami-based management consulting and benchmarking firm with a market cap well under $1B. You probably have not heard of it, and that is the point. Hackett specializes in AI-powered digital transformation services for enterprise clients, benchmarking operational performance against peers in procurement, finance, and HR. The company is tiny enough that no major fund is forced to own it, but its consulting revenue is directly tied to the exact enterprise AI modernization wave that Palo Alto's Nikesh Arora just described as a $1 trillion legacy modernization opportunity. The catalyst to watch: any acceleration in enterprise AI consulting spend as companies move from pilot programs to full deployments. Hackett sits right in that flow.

$IREN (Iris Energy) is a high-performance computing and Bitcoin mining company that is building out data center capacity on 100% renewable energy. The company's co-CEO just appeared on CNBC discussing community-focused operations in Childress, Texas, with 200 full-time local employees and a strong record on water and power efficiency. With Morgan Stanley flagging over $1 trillion in hyperscaler capex expected next year and data center demand showing no signs of cooling, IREN's renewable-native infrastructure positions it as a legitimate alternative to fossil-fuel-heavy competitors. The bear case is real: regulatory scrutiny on data centers is rising on both sides of the aisle, and the company is still burning cash as it scales. But the setup is interesting for anyone who thinks the HPC buildout has years left in it.

$ZUM (Zum Services) is the school bus technology company whose CEO Ritu Narayan recently appeared on CNBC talking about transforming American school district fleets with AI-based routing and driver management software. Zum works directly with school districts, deploying electrified buses alongside its platform. It is a niche that most investors dismiss as boring until it is not. Student housing pre-leasing just hit 89.1%, a sign that the broader education infrastructure economy is quietly recovering. If Zum can land a few major district contracts this fall and demonstrate unit economics, the stock could reprice fast on thin volume.

None of these are sure things. They are small, they are illiquid, and two of them are burning cash. But the best hidden gems usually look like that before they do not.
