The US photonics market is being rewritten in real time — by AI data center buildouts, co-packaged optics, and a re-shored semiconductor supply chain. For European photonics startups, this is the largest opportunity of the decade. And the window is narrower than most teams realise.
If you're a European photonics, silicon photonics, or optical-interconnect startup, you've probably watched the last 24 months with a mix of excitement and frustration.
Hyperscaler optics demand has exploded. Co-packaged optics is finally moving from research to procurement. CHIPS Act money is reshaping where US customers buy. And every AI cluster being stood up in Texas, Virginia, or Arizona needs the kind of optical infrastructure European labs have been working on for years.
You have the technology. You may even have European pilots.
But landing your first real US design win — at a hyperscaler, a defence prime, or a US fab partner — feels like trying to enter a market that doesn't quite know you exist yet.
The US photonics buyer is not the European photonics buyer.
This is the single most important thing European founders miss.
In Europe, photonics sales tend to flow through research consortia, Horizon-funded pilots, and long technical relationships. In the US, the buying landscape is concentrated, transactional, and moving fast.
Three buyer categories dominate:
- Hyperscalers and AI cluster operators — Microsoft, Google, Meta, AWS, Oracle, plus the new wave of AI-native infrastructure companies. They buy on roadmap fit, supply security, and unit economics at scale.
- US fab partners and OSATs — TSMC Arizona, Intel Foundry, GlobalFoundries, and the packaging houses around them. They buy on process compatibility and qualification timelines.
- Defence and aerospace primes — Lockheed, RTX, Northrop, plus the Anduril-class new entrants. They buy on ITAR posture, TRL maturity, and program alignment.
Each of these requires a different narrative, a different procurement vocabulary, and a different cadence.
A pitch built for a German Fraunhofer collaboration will not land at a hyperscaler optical-interconnect roadmap meeting.
01Lead with the AI infrastructure thesis.
Right now, the cleanest entry point for most European photonics startups is the AI data center buildout.
Optical I/O, co-packaged optics, linear pluggable optics, photonic switching — these are not academic curiosities anymore. They're line items in 2026 hyperscaler capex.
If your technology touches any part of the AI optics stack, position there first. The buyer is identifiable, the budget is real, and the urgency is unprecedented.
02Translate TRL into procurement language.
European photonics teams speak TRL fluently. US commercial buyers often don't.
You need a parallel vocabulary:
- What does "qualification" look like in our process?
- What are the failure modes and reliability data?
- What is the second-source story?
- Who has already piloted this, even at small volume?
This is what US buyers actually need to greenlight a design-in.
03Don't sell to "the US" — sell to three cities.
The US photonics buyer map is more concentrated than people think.
- Bay Area — hyperscaler optical teams, AI-native infra startups, optical I/O pioneers.
- Austin / Phoenix — fab-adjacent semiconductor and packaging procurement.
- Boston / DC corridor — defence primes, quantum, and federally-funded photonics programs.
You can run an effective US outbound motion targeting fewer than 400 named accounts across those three corridors. You do not need a 50-state strategy.
04Use AI outbound to compress the relationship-building cycle.
The traditional European playbook — conferences, posters, relationships built over years — still has value, but it cannot be your primary US motion. The market is moving too fast.
What works at Series A–B:
- AI-enriched account research on the ~300 named US accounts that matter for your wedge
- Multi-threaded outreach to the technical buyer, the procurement buyer, and the executive sponsor
- Sequences that lead with specific technical hooks (process node, wavelength, throughput, package format), not generic value props
- Same-week follow-up cadence, not same-quarter
This is exactly the kind of motion that AI tooling, properly configured, makes possible at a team of three.
05Show up like you belong on the US roadmap.
The final, often-overlooked piece: presence.
European photonics startups frequently feel like outsiders in US procurement conversations. The cure is not pretending to be American — it's showing up with the artifacts a US buyer expects: clear datasheets, a US-time-zone response cadence, a NYC or West Coast point of contact, ITAR posture clarity where relevant, and an executive who can be on a plane within a week.
You don't need a full US office. You need the appearance of one — and a system behind it.
The window is now.
AI infrastructure capex is at a generational high. Hyperscalers are placing photonics bets with 2027–2028 production timelines, which means qualification conversations are happening this year. The European photonics startups that show up in those conversations now will be the suppliers of the next decade. The ones that wait will watch the design wins go to faster-moving competitors.
