What RMBIO does
RMBIO (Rocky Mountain Biologicals, LLC) is a privately held specialty bioproducts manufacturer founded in 2004 and based in Missoula, Montana. The company produces sera, protein fractions, and cell culture media supplements for the research, bioprocessing, and clinical diagnostic industries. Its flagship offerings include the proprietary Fetalgro and Fetalgro EX lines — formulated FBS replacements positioned as cost-effective alternatives to traditional fetal bovine serum — alongside US Origin and USDA-approved FBS variants, treated sera (heat-inactivated, gamma-irradiated, IgG-depleted, dialyzed), specialty sera (calf, equine, porcine), classical cell culture media (DMEM, RPMI 1640, MEM, Leibovitz L-15), growth factors (bFGF, IGF-1), and diagnostic adjacencies such as thrombin, cholesterol concentrates, and Viral Transport Medium used in SARS-CoV-2 sample collection. Manufacturing is conducted at an FDA-registered, GMP-compliant, ISIA-certified facility in Missoula, with chain-of-custody validated to 9CFR standards.
The company operates a direct-to-consumer e-commerce model with global shipping, serving research laboratories, bioprocessing developers, clinical diagnostic manufacturers, and animal health customers. Pricing is per-unit and varies materially by grade: entry-level treated and specialty sera from $16-$42, Fetalgro standard from $28, Fetalgro EX at $25-$184, and premium US Origin FBS at $75-$670 per 500 ml. Revenue is not disclosed; with an employee count of 11-50 and the absence of any public funding rounds or M&A activity, RMBIO functions as a privately held, founder-led specialty supplier whose competitive position rests on regulatory credentials, proprietary serum alternatives, and breadth across adjacent biological inputs rather than scale or capital intensity.
