H2Ok Innovations builds patented inline spectral sensors paired with an AI solution to continuously monitor fluid signatures and optimize Clean‑In‑Place (CIP) and product changeovers. Its technology ingests 1 million data points per second and integrates with closed‑loop control systems for real‑time monitoring and error detection. Customers include Unilever, AB InBev, The Coca‑Cola Company, and Danone, and the company is deployed in factories across six continents. H2Ok says customers routinely cut CIP and changeover time by about 15% and reduce water, energy, and chemical usage by 10–20%. Founded in 2021 and headquartered at Greentown Labs in Somerville, MA, the company plans to productize its technology into an instantly deployable solution to scale AI across manufacturing. It recently raised a Series A to accelerate commercialization and broader factory deployments and has earned supplier recognition from Unilever and AB InBev. H2Ok Innovations develops integrated hardware and software to minimize liquid usage and boost efficiency in manufacturing operations. The company was founded by siblings Annie and David Lu, drawing on a family background in chemical manufacturing and lean manufacturing principles. Annie left Harvard and, with her brother, launched the startup to apply their chemistry and factory insights to industrial liquid conservation. H2Ok is headquartered at Greentown Labs in Boston and is already generating revenue. Since its inception two years ago the company has attracted investor attention and industry recognition. Founders earned a spot on Forbes 30 Under 30 in 2022 and H2Ok received Unilever’s Start-up of the Year award in March.
