Hardly anyone talks about the tiny companies building the AI supply chain underneath them.
Found a few interesting names down the market cap ladder:
$ALMU $VLN $GCTS $KOPN $SVCO
These aren’t AI chatbot companies.
I’ve mentioned a few before.
Just keep these in mind.
They’re enabling connectivity, photonics, sensing, displays, semiconductor design, and data movement.
The stuff AI infrastructure actually depends on.
$ALMU (~$400M MC)
One of the more interesting photonics stories I’ve found.
They’re developing III-V semiconductor technology on silicon aimed at AI optics, sensing, defense, and quantum applications.
Partnered with Tower Semiconductor and Sumitomo.
NASA and defense-related contracts continue piling up.
Only guiding for about $4-5M revenue this year, so valuation isn’t based on current sales.
It’s based on the possibility that AI optical interconnects become a major bottleneck over the next decade.
High risk. High reward.
$VLN (~$230M MC)
Valens Semiconductor builds high-speed connectivity chips used in ADAS, robotics, machine vision, industrial systems, and automotive networks.
Q1 revenue reached $16.9M.
Guiding roughly $75-77M for 2026.
Gross margins above 60%.
Three new automotive OEM wins and A-PHY adoption continue ramping.
Only trades around 3-5x sales despite exposure to autonomous systems and edge AI connectivity.
Interesting value play in the group.
$GCTS (~$220M MC)
A small-cap 5G and wireless semiconductor company.
Builds modems, transceivers, and IoT connectivity chips used in fixed wireless access, industrial devices, routers, and emerging NTN/satellite applications.
Q1 revenue grew 287% YoY.
5G chipset shipments increased 58% sequentially.
Still very early with only a few million in revenue and ongoing cash burn.
But if fixed wireless and industrial 5G deployments accelerate, the upside could be significant.
One of the more speculative names here.
$KOPN (~$1B MC)
Microdisplays, optics, thermal imaging, drones, AR/VR, soldier systems.
Basically a defense-tech and display company hiding inside the semiconductor ecosystem.
Entered 2026 with roughly $37M defense backlog.
Recent awards include $21.5M thermal imaging follow-on work plus MicroLED development programs.
Management guiding roughly $52-60M revenue this year.
If defense spending, drones, and wearable AI systems keep expanding, Kopin sits in a pretty interesting niche.
$SVCO (~$380M MC)
One of the few pure-play small-cap semiconductor software names.
They provide TCAD simulation, EDA tools, and semiconductor IP used to design chips before they’re ever manufactured.
Think digital twins, photonics simulation, power semis, AI-driven manufacturing optimization, and advanced process modeling.
Q1 bookings grew 26% YoY.
Backlog sits around $46.6M.
TTM revenue is roughly $66M with gross margins near 87%.
Everyone talks about AI chips.
Someone has to design and simulate them first.
That’s where SVCO fits.
Everyone wants to own the AI model.
I’m more interested in the bottlenecks.
Photonics.
Connectivity.
Optical interconnects.
Sensing.
Chip design.
Data movement.
As AI clusters scale, moving and designing data efficiently may become just as important as generating it.
Feels similar to how power infrastructure was ignored before data center demand exploded.
Not saying these become the next
$NVDA.
But the market caps are tiny compared to the problems they’re trying to solve.
$TSM $SIVE $AAOI $LITE $BE $SNDK $CRWD $SNPS $COHR $CIEN $CDNS
$AVGO $MRVL $QCOM
Worth digging into.
