What True Indicating does

True Indicating, LLC is a Toledo, Ohio-based, founder-owned private company founded in 2017 that manufactures and sells sterilization and disinfection monitoring products and services. Its portfolio centers on biological indicators (spore strips, spore discs, spore ampules, self-contained biological indicators, and spore suspensions) and chemical indicators (ISO 11140-1 Types 1, 2, 4, 5, and 6) covering six sterilization modalities: steam, dry heat, ethylene oxide, radiation/irradiation, vaporized hydrogen peroxide, and formaldehyde. The flagship InstaTRU™ Instant Biological Indicator (FDA 510(k) cleared under K210481) provides sterilization verification in 20 seconds without a dedicated reader or incubator, and is supported by proprietary modified growth media (PGM-100, GGM-100), a Mini Dry Bath Incubator, and QR-code-based digital result logging. The company holds ISO 13485:2016 certification, with products compliant to USP, ISO 11138-1/-2/-3/-4, and ISO 11140-1 standards, and is led by CEO and founder Bob Napierala and Chief Scientific Officer Thomas Riha, whose combined 35+ years of sterilization assurance experience underpins the technical platform.

The company operates a direct-to-consumer e-commerce distribution model through its own website, with quote and sample request workflows for custom and enterprise buyers. End markets include healthcare, dental, pharmaceutical, life science/laboratory, and industrial customers. Product pricing is unit-based (pay-as-you-go) and ranges from approximately $10 for small accessories to $650 for high-volume biological indicator packs, with most chemical indicator strips priced between $23 and $166. Beyond finished products, the company sells indicator inks to OEMs, offers population and resistance verification testing services, and provides custom development and consulting for novel sterilization modalities. In-house manufacturing at the Toledo headquarters is positioned as a cost-efficiency lever.

True Indicating is privately held with no disclosed institutional investors, no disclosed funding rounds, and no parent company, operating as an independent, founder-led specialty manufacturer in a regulated medical device / sterilization assurance niche adjacent to larger incumbents. The business model is fundamentally transactional B2B/B2B2C sales of consumable monitoring products, complemented by professional services and custom development revenue. No revenue, headcount trend, or unit-volume data is publicly disclosed, and the company has not signaled international expansion or AI/digital platform investment beyond QR-code result logging.
