Guardion Inc.

Guardion Inc., a small business based in Burlington, Massachusetts, develops advanced sensor and detector technologies for federal agencies under the Small Business Innovation Research (SBIR) program, operating exclusively as a prime contractor on firm fixed-price Phase I and Phase II contracts.

Guardion specializes in ion detection, graphene-based sensors, and two-dimensional material-based detection systems with applications across space technology, chemical and biological defense, environmental monitoring, and human spaceflight. The company's core capability portfolio centers on cold cathode electron sources for mass spectrometers, portable gas analyzers for habitable environments, and high-gain detectors optimized for low size, weight, and power constraints. Representative work includes a $900 thousand Phase II SBIR contract awarded by NASA's Shared Services Center on May 15, 2023, for two-dimensional material-based detectors for mass spectrometers (completion January 31, 2026); a $224,941 Phase I SBIR award from NASA on September 30, 2026, for cold cathode electron sources for lunar and planetary mass spectrometers; a $149,982 Phase I SBIR contract from NASA on September 29, 2025, for a portable major and trace constituent gas analyzer for habitable environments; and a $74,953 Phase I SBIR purchase order from the Air Force Research Laboratory on January 18, 2025, for an ion detector supporting chemical detection, CBRN defense, and environmental monitoring.

Customer concentration is heavily weighted toward NASA, which accounts for seven of eleven total awards and $3 million of the $3.1 million combined potential value (100% coverage across the top five agencies). The Air Force Research Laboratory and the National Science Foundation represent the secondary customer set with single awards each. All awards carry total small business set-asides; Guardion competes exclusively under SBIR, reflecting its small-business profile and the R&D nature of its work. Work is performed at the company's Burlington, Massachusetts facility across both Phase I (typically $150 thousand range) and Phase II (up to approximately $900 thousand) research efforts. Two awards with combined potential value of $1.5 million face ultimate completion within the next twenty-four months, representing near-term recompete exposure. The vendor carries no subcontract footprint and operates entirely as a prime.
