Eagle Harbor Technologies

What Eagle Harbor Technologies does

Eagle Harbor Technologies (EHT) is a Seattle-based pulsed-power equipment company founded in 2005 that designs and manufactures solid-state pulsed-power systems for research, defense, and semiconductor customers. Its core technology replaces legacy thyratron and pulse-forming-line architectures with solid-state switching topologies, enabling more compact, controllable, and repeatable high-voltage pulse generation. The product catalog includes catalog units such as the Spartan rack-mount pulsed-power generator and the nanosecond NSP-IA supply, alongside custom-engineered systems for national-laboratory fusion and plasma-physics programs; under the EHT Semi brand, the company is now extending its switching technology into semiconductor processing tools.

The company operates from a 35,000 sq ft Seattle facility with manufacturing capacity for approximately 100 units per year and holds more than 85 patents covering its pulse-generation architectures. Revenue is generated primarily through the sale and customization of pulsed-power equipment to U.S. national laboratories, DOE/DoD prime contractors, university research groups, and (under EHT Semi) semiconductor OEMs, with pricing on a quote basis reflecting the custom-engineering content of each system. R&D has been sustained by a long track record of SBIR awards, including twelve Phase II programs and an active DOE SBIR Phase II award announced in January 2024.

In January 2026, Jabil made a strategic minority investment in the company and entered a manufacturing collaboration to scale EHT Semi semiconductor production. The company's go-to-market combines direct sales to national-lab and defense primes with a distribution relationship (Sky Blue Microsystems) covering EMEA research accounts, positioning it as a specialist supplier rather than a volume hardware vendor.
