Growing up in Hawaii, Dylan DiMarchi was a sailor. And he watched as the weather shifted throughout his childhood, and adolescence.
“I’ve been sailing for two decades now, and noticing patterns in the weather is our main job as sailors,” he said. “There are definitely changes in certain venues. Like, in my home venue [on Oahu] Kāneʻohe, we’ve seen wind directions and strength definitely and measurably change over the last two decades. While it’s hard to know exactly what dynamics are leading to that change on that island in the Pacific, it’s really important we spend a lot of time looking at weather models.”
DiMarchi has spent much of his life thinking about weather—his experience sailing is connected to his life as an entrepreneur, as cofounder and CEO of Eventual, a startup helping insurance carriers and homeowners predict climate-driven pricing changes. Founded in 2023 by DiMarchi and Youssef Doss, Eventual built a model—based on historical and current data from 20 million homes and 150,000 commercial properties—that estimates how insurance prices on homes in the U.S. will change in the coming years.
“We’re focused on not just solving insurance generally, but on a relatively new stress—this unpredictability and timing problem.” said DiMarchi. “Many of our customers have seen premiums, often unexpectedly, increase 50% to 100% over the last three or four years, which is wild to say out loud.”
