Substrate is a semiconductor manufacturing company building America's next-generation chip foundry, with the stated mission of returning the United States to dominance in advanced semiconductor fabrication. Rather than designing chips, the company is inventing manufacturing technology intended to extend Moore's Law while lowering the cost of building state-of-the-art fabs and the wafers they produce. Substrate is a hard-tech / advanced-manufacturing venture backed by General Catalyst; it is a physical-infrastructure company and does not publish a public developer API, SDKs, or developer documentation. This API Evangelist profile was surfaced from the General Catalyst portfolio and enriched with the provider's public identity and security surface.
