What Fortify does

Fortify is a Boston-based materials science and additive manufacturing company founded in 2016 that developed a proprietary Digital Composite Manufacturing (DCM) platform for producing advanced composite and ceramic components, with particular specialization in dielectric materials for radio frequency (RF), microwave, and millimeter wave (mmWave) applications such as radar systems, satellite communications, and phased-array antennas. The company positioned itself as a dual-use technology provider serving aerospace and defense, medical technology, and telecommunications customers, with a reported ecosystem of over 50 partners and strategic backing from defense primes Lockheed Martin Ventures and RTX Ventures, as well as intelligence community capital from In-Q-Tel and non-dilutive support from the U.S. Department of Energy and the National Science Foundation.

The company’s go-to-market was enterprise field sales targeting defense and aerospace primes, with technical marketing at industry conferences such as the 2024 IEEE Phased Array Symposium. Its revenue model centered on one-time licensing and sale of the DCM platform and associated advanced materials — pricing was not publicly disclosed. Fortify accumulated approximately $45 million in disclosed funding across seed, Series A ($20 million in 2021 led by Cota Capital), and later strategic rounds ($12.5 million in 2023 led by Lockheed Martin Ventures and RTX Ventures), alongside NSF, DOE, and IQT funding.

By 2026, Fortify’s advanced materials intellectual property portfolio — specifically dielectric materials for RF, microwave, and mmWave applications — was acquired by Tethon 3D and repositioned as an acquired brand within Tethon’s 3D printing materials platform. The company’s primary website (3dfortify.com) is no longer resolving, and operating status is recorded as acquired, indicating that Fortify has effectively wound down as an independent entity even though earlier 2022–2023 signals had indicated active commercial scaling.
