Singapore leads climate-tech deal activity in Southeast Asia

Singapore logged around $84.7m across 10 deals.

Since 2020, Singapore has consistently led Southeast Asia’s climate-tech investment by both deal count and deal value—Indonesia followed closely whilst the rest of the region sees only sporadic, smaller quarters, according to Kickstart Ventures’ H1 2025 report.

In H1 2025, startups headquartered in Singapore and Indonesia drew around 97% of all climate-tech capital in the region.

Singapore logged around $84.7m (US$66m) across 10 deals—indicating larger average cheques—whilst Indonesia booked around $78.3m (US$61m) across 13 deals, pointing to more transactions but slightly smaller tickets.

The rest of SEA barely figured: Malaysia tallied 3 deals (around US$2m), Vietnam 1 deal (around US$2m), and Thailand 1 deal.

The report showed Singapore’s leadership on both volume and value throughout, with periodic spikes, and Indonesia consistently in second; other markets appear sporadic and small by comparison.

The largest disclosed ticket in the half was around US$21m for an Indonesia-based Energy company. Fundraising skewed early-stage (Seed–Series A, plus select venture/debt). Energy and Agriculture anchor deal flow, with additional activity in low-carbon mobility and waste & recycling.
