Kevin Sofen

Kevin Sofen did not come into water through engineering or a treatment plant. Kevin Sofen came in through a microphone, starting a podcast in 2017 called Rethinking H2O after meeting an engineer named Jack Barker who kept finding new ways to move and treat water. The idea that stuck with him was less about pipes and more about people, and his guiding north star became a book called Blue Mind by Wallace J. Nichols, the study of why humans are happier, healthier and more productive when they are on, in, near or around water. Kevin Sofen has looked at water through that human, almost spiritual lens ever since, and in 2020 he turned Rethinking H2O into the SDG Talks Podcast.

Kevin Sofen's day job for more than fourteen years was at W. S. Darley & Co., a fourth-generation, family-run firefighting and emergency-equipment manufacturer founded near Chicago in 1908. Darley is not a water-tech startup, and that is the point: it builds the gear that shows up when water systems fail, from compact pumps to water-purification kits and "water in a box" packaged drinking water for disaster response. Kevin Sofen spent his time there bringing exactly those kinds of new solutions to market, including virtual-reality training and robots for first responders, and he eventually ran innovation for the company before moving in 2023 to advise it and to lead technology for the International Association of Fire Chiefs.

Kevin Sofen's distinctive argument, and the spine of his (don't) Waste Water episode, is that water is not a single box on the UN's Sustainable Development Goals list. The seventeen SDGs are the global to-do list the United Nations set for 2030, and most people file water under SDG 6, clean water and sanitation. Kevin Sofen pushes back on that, walking through how access to safe water sits underneath no poverty, zero hunger, good health and quality education all at once, because a community hit by floods in India or Pakistan cannot get back to school or work or farming until the water is dealt with first. A healthy, functioning watershed, in his framing, is a piece of economic infrastructure that is almost impossible to price and badly undervalued.

Kevin Sofen has put that worldview to work on the ground, most concretely in Flint, Michigan, where he worked with a charity called the National Clean Water Collective to run 100 water-quality tests across the city and turn the results into a heat map. The samples came back showing elevated trihalomethanes and chloroform, traces of Legionella and roughly average lead, and the point was not just to publish numbers but to drive action. Working with mail-in testing from SimpleLab, whose founder Johnny Pujol he openly admires, Kevin Sofen sketched a tiered fix that runs from packaged water through point-of-entry and point-of-use filtration to ongoing testing and education, a short-to-medium-term bridge he reckons costs roughly $3,000 to $4,000 per home until the long-term, billion-dollar pipe replacements finally arrive.

Kevin Sofen's bet for the next thirty years is climate adaptation sitting alongside, not instead of, cutting carbon, a point he worked through with John Robinson of Mazarine Ventures and sums up as "a world of and," and his one-word answer for resilience is decentralization, of treatment, of pumps, of power. All of it traces back to one specific place. Kevin Sofen has spent his whole life on Elkhart Lake in Wisconsin, the third-deepest lake in the state, and he sits on the board of its lake-improvement association, "Keep Elkhart Blue," which he calls his north star for protecting one watershed completely. That is the tell with Kevin Sofen: the global SDG argument and the local glacial lake are the same argument, just at different scales.

“It's not a world of or, it should be a world of and. We need to do both.”

Kevin Sofen is, in the end, a connector more than a technologist: a podcaster and innovator who is most useful in the gap between the people who can fix water and the people who do not yet know they need to, which is exactly the gap a curious investor should be watching.
