About the company
City Labs, Inc., a minority-owned, Hispanic American small business headquartered in Miami, Florida, designs, manufactures, and develops advanced tritium-based power sources and betavoltaic technologies for defense, space, medical, and specialized electronics applications, operating exclusively as a prime contractor on federal R&D and manufacturing awards. The company specializes in miniaturized, long-life nuclear power conversion systems — radioisotope heater units, betavoltaic batteries, cryptographic key retention systems, and autonomous sensor platforms — positioning itself as a niche supplier in the federal nuclear power and advanced materials space.
City Labs' recent customer base concentrates heavily on the Department of the Air Force. The Air Force Research Laboratory (AFRL) accounts for ten awards and $10.4 million in combined potential value, anchoring the vendor's footprint through multiple SBIR Phase I, II, and III contracts focused on tritium batteries, ion engines for small satellites, self-powered imaging sensors, and cryptographic security systems. NASA's Shared Services Center places the second-largest volume (nine awards, $2.2 million combined potential value) through research grants under the NASA Innovative Advanced Concepts (NIAC) Program and feasibility studies for autonomous tritium-powered sensors. The National Heart, Lung, and Blood Institute (via HHS) funds medical-device research on betavoltaic power sources for leadless cardiac pacemakers. The Defense Advanced Research Projects Agency awarded a $1.5 million Other Transaction Agreement in February 2026 for the Rads to Watts Program, focusing on watt-class radiation-hardened radiovoltaics for direct nuclear power conversion through August 2028. The Department of Defense's Washington Headquarters Service placed a $7.27 million definitive contract in December 2024 for the STAR Autonomous Nuclear Tritium Sensor (ANTS) program through 2027. Together, the top five customers cover 100 percent of combined potential value.
City Labs operates entirely within the Small Business set-aside universe on SBIR and research R&D work. Ten of the vendor's twenty-six prime awards carry Total Small Business designations; four carry SBIR Phase designations (Phase I, II, or III); others are unset-aside research grants. The vendor competes across AFRL SBIR vehicle competition, NASA grants, NIH research funding, and open Defense and civilian federal R&D procurement. No IDIQs, GWACs, or standing BPAs appear in the source data. Activity has remained flat at four to five awards per year over 2021–2025, with six awards (combined potential value $12.9 million) reaching ultimate completion within the next twenty-four months, exposing City Labs to recompete risk on AFRL SBIR follow-on work and NASA feasibility studies. The vendor carries no federal subcontract footprint and receives no sub-awards; all twenty-six awards are direct prime contracts or grants. Top procurement codes center on National Defense R&D Services and applied research in nuclear and space technologies, reflecting the vendor's deep specialization in tritium power systems and radiation-hardened components.
