About blue activity
blue activity is a Heidelberg-based CleanTech startup founded in 2021 that replaces chemical biocides and metal-based polymers in industrial evaporative cooling-water systems with natural microorganisms and biopolymers. Its "all-round carefree" service combines sustainable reagents with online monitoring and on-site operation, targeting lower operating costs, reduced water consumption and improved wastewater quality at factories running open cooling towers. The company is led by CEO Lars Havighorst and CTO Michael Simon and claims its approach cuts cooling-water OPEX by up to 15% while eliminating hazardous substances in line with German §6/§7 Hazardous Substances Ordinance goals.

Key Highlights
AI InsightsUnusually large early-stage round for the German B2B hardware/deeptech sector — starting-up.de journalism flags the "seed" label as late-seed given Austrian investor Epoona backed the company as early as 2023.
