Best Sustainability Tech Companies in Singapore
The 234 best Sustainability Tech companies in Singapore in 2026, ranked by funding and momentum. Funding, investors, founders, valuation, tech stack and live signals. Top: Lion TCR.
Ranked by disclosed equity funding and recent momentum, the Sustainability Tech companies in Singapore tracked here represent one of Southeast Asia's more consequential clean-economy buildouts. $471M in total disclosed funding across 234 companies. No unicorns yet, but the trajectory is real. Blue Planet leads the directory at $40M raised, followed by VFlow Tech at $13M and Amperesand at $12M, and what strikes me about those figures is how capital-efficient this cohort looks relative to the scale of the problem they're addressing. The global sustainability tech market sat at $16.2B in 2022 and is forecast to reach $122.7B by 2032, a 23.8% CAGR that reflects genuine demand for low-carbon infrastructure, smart grid deployment and next-generation battery technology.
So what's actually moving capital right now? EV battery tech and drive system innovation are the hottest themes in the sector, consistent with what you'd expect from a regulatory environment still catching up to the pace of deployment. The absence of unified green technology regulation remains a structural headwind, even as investors like Wavemaker Impact and SEEDS Capital stay active across the Singapore pipeline. Sustainability tech's momentum is no longer a thesis, it's a funding pattern, and this directory gives you the clearest read on where Singapore's disclosed dollars are actually going.
