Ursa Major Technologies
Ursa Major Technologies Inc. is an American aerospace and defense propulsion manufacturer founded in 2015 by Joe Laurienti, a former SpaceX and Blue Origin propulsion engineer, and headquartered at 19750 Co Rd 7 in Berthoud, Colorado, with additive manufacturing operations in Youngstown, Ohio. The company designs, builds and hot-fire tests liquid rocket engines, solid rocket motors and in-space propulsion systems for space launch, hypersonics and U.S. and allied defense customers. Its product line includes the 5,000 lbf Hadley oxygen-rich staged-combustion liquid engine — the first Ursa Major engine to reach flight qualification for hypersonic missions — and Draper, a storable, throttleable, restartable engine for tactical hypersonic strike, missile defense and rapid in-space maneuver, alongside a solid rocket motor line validated through static fire and a chemical propulsion capability for tactical satellite bus systems. Ursa Major was the first American company to successfully fire an oxygen-rich staged combustion engine; it states it has delivered more than 100 engines and logged over 100,000 seconds of hotfire testing, with engines and motors more than 80 percent 3D printed by mass. The company is AS9100D, ISO 9001 and CMMC Level 2 certified. Ursa Major is a hardware manufacturer selling to government and prime-contractor customers: it publishes no public developer API, SDK, CLI, developer portal or machine-readable API contract of any kind.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles Ursa Major Technologies the way a machine reads it — 1 machine-readable artifact, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Ursa Major Technologies scores 13.5/100 (emerging), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Why this profile is thin
Ursa Major builds rocket engines and solid rocket motors as physical hardware for defense and space-launch customers, so there is nothing to expose as an API — ursamajor.com is a WordPress marketing site whose only machine-readable output is a Yoast-generated llms.txt with empty link targets, and no api., developer., docs. or portal. subdomain resolves at all.
This is an honest zero, not a gap in our research. Ursa Major Technologies does not appear to expose an API, so there is nothing here for us to index and nothing for them to fix.

This is an independent, third-party profile of Ursa Major Technologies, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
