Best Environment Companies in Israel
The 135 best Environment companies in Israel in 2026, ranked by funding and momentum. Funding, investors, founders, valuation, tech stack and live signals. Top: O.P.C. Energy.
Israel's Environment sector has more going on than the headline number suggests, but let's start there: 135 companies, $853M in disclosed funding, zero unicorns. O.P.C. Energy leads the pack at $288M raised, with Enlight Renewable Energy and Solel Solar Systems each pulling $145M, and the rest of the field drops off sharply from there. That concentration tells you something about where serious capital is landing, which is large-scale renewables and energy infrastructure, not early-stage experiments. The global environment services market sits at roughly $68.8B in 2024 and is forecast to reach $73.5B by 2025, a 5.3% CAGR according to The Business Research Company, driven hard by climate regulation and infrastructure mandates. So you're not looking at a sleepy vertical.
What makes this quarter feel live is the demand signal beyond the funding tables. Environmental and renewables apps are posting median install growth of around 20% year-on-year across 161 tracked products, and AI is accelerating the whole stack from emissions monitoring to grid optimization. Investors like Hutchison Kinrot and Capital Nature are active here, and how startups adapt strategy to external environmental shifts is increasingly the differentiator between companies that scale and ones that stall. I'd watch the mid-tier closely. The gap between nT-Tao at $28M and the top names is where the next breakout probably lives.
