Eyal Harel, CEO of BlueGreen Water Technologies, has spent 12 years going where most companies won’t: toxic, collapsing water bodies that communities rely on—and where “solutions” usually mean waiting for the next disaster. Eyal has seen how bad it gets up close: sewage flowing into lakes, drinking water pulled from the other side, and ecosystems turning into dead zones you can’t swim in, fish from, irrigate with, or even touch.

In our conversation, Eyal explains why harmful algal blooms are a water pandemic—and why the world still treats water like air: essential, invisible, and something nobody wants to pay for. He breaks down BlueGreen’s approach: surgically trigger a collapse of the toxic species, then let biodiversity rebuild the ecosystem fast.

Then it turns into the hard business reality: how do you build a company when the problem is enormous, but the market doesn’t exist? Eyal unpacks why investors struggle to price water innovation, why government budgets lag the crisis, and how BlueGreen is using carbon markets as a financing engine to scale water restoration—without relying on handouts.
