Customers
PURE sells to food-industry end users that need antimicrobial control across production, handling, and transport. Its products are also sold through distributors, which broadens access to smaller accounts and regional markets. The customer base includes restaurant chains, food processors, food manufacturers, and transportation companies, plus third parties that buy SDC as an ingredient or formulation input.

Strategy
PURE’s strategy centers on commercializing its SDC platform in food safety, expanding through distributors, and adding new products and applications. It also seeks third-party partnerships for approvals outside the U.S. and aims to protect its intellectual property while broadening the technology platform into additional revenue streams.
Distributors extend reach, reduce logistics burden, and speed market access.
International approvals can open new markets without building a full direct-sales footprint.
New formulations can broaden the platform beyond current food-safety uses.
Patent protection supports differentiation and helps defend the SDC platform.
Geography
PURE is a U.S.-based company and its registered products are cleared for use in the United States, with additional registration in Canada. The business is built around domestic commercialization and distributor-led reach, while also pursuing third-party approvals for markets outside the U.S. Geography matters because regulatory approvals, local distributor coverage, and food-safety standards shape where the products can be sold.
Risks
PURE faces commercialization risk because its products must gain broader acceptance in a competitive food-safety market where customers are price-sensitive and incumbents are larger and better resourced. The company also depends on regulatory approvals, distributor execution, and external financing, so delays in sales adoption or capital access could materially affect operations.
