Mesh Optical raises $50M to build US-manufactured optical interconnects for AI GPU clusters
Feb 18, 2026 with Travis Brashears
Key Points
- Mesh Optical raises $50 million to manufacture optical transceivers that replace power-hungry components in NVIDIA GPU clusters, eliminating retimers entirely to cut data center power consumption.
- The startup is building a US production line in Gardena, California after discovering no domestic manufacturer exists for high-precision optical transceiver packaging, a capability vendors previously required Chinese credentials to access.
- Co-founder Travis Brashears applies SpaceX's engineering ethos of deleting parts and questioning requirements, already removing several components from his design and betting the company on young engineers to drive accountability.
Summary
Mesh Optical Technologies raised $50 million across seed and Series A to manufacture optical transceivers for AI data center infrastructure in the U.S. Co-founder and CEO Travis Brashears launched the company on the same day as Jensen Huang's birthday.
Brashears spent his early career in laser technology, working with a professor at UCSC starting in high school and later designing space laser communication systems at SpaceX. That background directly informed Mesh Optical's first product: a pluggable transceiver that replaces a power-hungry component called a retimer or DSP inside GPU clusters. Every NVIDIA GPU in a cluster needs four to five of these optical interconnects to connect GPUs together and maintain coherence. Mesh's version eliminates the retimer entirely, cutting power consumption.
The transceiver connects GPUs via fiber optic cable within data centers. Brashears is setting up the production line in Gardena, California, deliberately colocating engineering with manufacturing as he learned at SpaceX. Sample testing begins within a month, with production reaching millions of units by 2027.
Execution risk is high. Demand risk is not. Brashears calls demand "infinite" because compute scales with intelligence, and transceiver demand scales with compute. Hyperscalers, cloud builders like Neo, and other compute deployers are all potential customers. Mesh plans to match volume carefully to its customer pipeline rather than overscheduling early production.
A strategic advantage lies in manufacturing location. Nearly all transceivers today are made overseas in China and Thailand. When Mesh bought a high-precision flip chip die bonder, the vendor asked for a Chinese social credit number, indicating no one has built this capability in the U.S. before. Mesh is sourcing dies from non-Asian foundries and doing all semiconductor packaging in California.
Brashears carries one core operational lesson from SpaceX: question requirements and delete parts and processes. Every component you remove eliminates a failure mode and speeds assembly. The company has already deleted several parts from its design compared to competitors. Brashears also notes that SpaceX bets the company on young engineers, a forcing function that breeds both accountability and systems-level understanding.
Mesh Optical has 15 employees and is already outgrowing its current space. The immediate priority is proving yield and scaling production. The longer-term vision includes optical interconnects for space-based systems, not just ground data centers.
