info_outline“If you say something over and over often and enough, it becomes true because perception is reality.”
Paul O’Callaghan has built a career at the intersection of water science, wastewater realities, and the practical question every operator and executive eventually faces; what actually moves innovation from idea to adoption.
As Founder and CEO of BlueTech Research, Paul explains how his team helps decision-makers put capital to work more efficiently in water by reducing uncertainty and separating signal from noise. He describes patterns he’s watched repeat across water entrepreneurs, pilots, and product market fit, and why “innovation” often breaks down simply because utilities, investors, and founders are using the same word to mean different things.
Capital, fit, and the language gap 
Paul unpacks what it takes to align an investor’s expectations with a technology’s true pathway to scale. He contrasts different “types” of innovation and why matching the right investor, entrepreneur, market, and timeline matters as much as the technology itself. The conversation also highlights why solving a problem someone has today is often a safer starting point than betting everything on a problem that might arrive tomorrow.
Regulations as a driver and a risk
Regulation matters in water and wastewater, but Paul cautions against building an entire business on the hope that rules will create a market on schedule. He walks through timing risk, enforcement uncertainty, and why tracking policy momentum matters as much as tracking the text of the regulation itself. He also notes a shift toward more “aspirational” regulation focused on reuse, regeneration, and systems-level outcomes.
Storytelling that changes adoption
From Brave Blue World to Our Blue World, Paul shares what he learned about making water personal and compelling without reducing it to doom-and-gloom narratives. The stories he tells connect to a core professional challenge: technologies enable outcomes, but adoption accelerates when people can see and want the “better” future those outcomes create.
