Southeast Asia has drawn about $1.1 billion climate tech funding across 268 rounds as of June 2026, Singapore leading with $872 million of total funding, Tracxn said Friday.
The firm said in a statement that seed and early-stage rounds account for approximately all capital deployed across the period.
The five most-funded sectors are solid waste management, smart grid, energy efficiency, air pollution management, and renewable energy, align with the region’s energy-transition and industrial decarbonization priorities, and the first exits signal an ecosystem beginning to move beyond initial formation.
Seed and early-stage rounds funding peaked at $288 million in 2023 and recorded $166 million in 2025.
In 2026 year-to-date, four rounds totaling about $17 million have been recorded across SLEEK ($9 million Series A, Bangkok), Polybee Systems ($4M seed, Singapore), Dat Bike ($4M Series B, Da Nang), and NEU Battery Materials (undisclosed seed, Singapore), compared with $41 million across 14 rounds in the first half of 2025.
Meanwhile, solid waste management tech leads at $105 million, anchored by Blue Planet ($46 million Series B) and Green Li-ion ($41 million Series A).
Smart grid follows at $97 million, with Amperesand’s $80 million Series A, the largest single round in the dataset.
Energy efficiency tech stands at $77 million, air pollution management tech at $71 million, and renewable energy tech at $64 million, with VFlow Tech ($21 million and $10 million Series A) among the notable raises in renewables.
Within each sector, one or two scaled raises account for the majority of the sector total.
Together, the top five sectors cover waste management, grid infrastructure, energy efficiency, air quality, and renewable generation.
Singapore’s funding was led by Beam ($135 million), Amperesand ($93 million), and Neuron ($81 million).
Indonesia follows at $162 million, led by ALVA ($50 million), Charged ($48 million), and MAKA ($38 million) all in electric vehicles.
Vietnam has recorded $53 million, with Dat Bike ($51 million) accounting for the substantial majority.
Thailand ($20 million) and Cambodia ($16 million) have seen early-stage activity.
The five most active investors are SEEDS Capital (15 rounds), Entrepreneur First (13), Wavemaker Impact (10), SGInnovate (8), and East Ventures (6).
SEEDS Capital and SGInnovate are both government-linked and active primarily at seed and early stage.
The ecosystem has produced 20 acquisitions to date, concentrated in Singapore.
Acquired companies include Terrascope (decarbonization software, acquired by XeleratedFifty in March 2026), Durapower Group (EV batteries), BBP (energy efficiency), Anacle Systems (energy management), and GESITS (electric motorbikes).
Ten companies have listed publicly across Thailand, Malaysia, Indonesia, and Singapore.
Together, the ecosystem has recorded 30 exit events, acquisitions and public listings while remaining predominantly seed and early-stage by round count and capital deployed.
In 2026 year to date, four rounds totaling about $17 million have been recorded, all at seed or early stage.
First half of 2025 recorded $41 million across 14 rounds.
The four rounds are SLEEK ($9 million Series A, Bangkok), Polybee Systems ($4 million seed, Singapore), Dat Bike ($4 million Series B, Da Nang), and NEU Battery Materials (undisclosed seed, Singapore).
Bangkok accounted for about 51 percent of the first half of 2026 funding, driven by the single SLEEK raise.
Investors across the four rounds include SEEDS Capital and SGInnovate at seed stage, alongside January Capital, Krungsri Finnovate, and Kymco Capital in SLEEK’s Series A, and TVS in Dat Bike’s round.
The half-year also recorded one acquisition – Terrascope, acquired by XeleratedFifty in March 2026.
