Halo is a drink-spiking detection technology company. Its enzyme-coated products (straws, cups, stirrers, shot glasses) change color and become luminous within 5-10 seconds of exposure to common spiking drugs (GHB, Rohypnol, Fentanyl, Ketamine), providing continuous, discreet, single-use protection for consumers and venues.

Single-use, spray-applied enzyme coating on straws, disposable cups, stirrers, and shot glasses that continuously monitors drinks for over 45 minutes. When exposed to spiking drugs (GHB, Rohypnol, Fentanyl, Ketamine), the product changes color and becomes luminous within 5-10 seconds, discreetly alerting users to potential drink tampering. Uses proprietary micro-encapsulation technology to protect enzymes from degradation by acidic drinks while remaining 100% food-safe even with leakage. Detects the drug families responsible for 95% of spiking cases and integrates seamlessly into existing drinkware manufacturing processes at minimal added cost (~$0.002-$0.005 per unit).
