| WaterClick | WaterClick is a software company dedicated to accelerating the digitization of small and medium-size water and wastewater utilities. Despite best intentions, many communities find themselves unable to effectively digitize their utility, translating into continued operational inefficiencies, less visibility into asset health & system risks,and an inability to efficiently report key metrics to government, regulators, and ratepayers. Benefits are widely understood, and solutions, of course, exist; however, the way ‘digital water’ is being packaged and sold to smaller utilities is, in fact, the barrier to utility modernization. The net result of stalled digitization is increased public health, safety, and environmental risks.WaterClick recognized that the way to accelerate utility modernization is NOT to lecture utilities about the benefits of digitization, rather, offer them a digital solution that meets their unique budget and operational needs. We operate a platform that streamlines the onboarding of digital tools, offers pre-configured integrations, and delivers a cloud-based dashboard and support desk, all via a subscription model. At the core of this ‘Platform as a Service’ (PaaS) business model is WaterClick’s proprietary ‘Click-in’ integration, which allows smaller utility operators to benefit from recent innovations in sensing, analytics, and decision support software that the larger utilities are already using; however, with WaterClick operators can simply add/remove features that meet their needs and budget. And for technology companies with innovative ‘digital water’ solutions, WaterClick is now an effective path to customer. WaterClick: Utility Digitization Simplified |  | Seed | Jun 01, 2021 |  |
