H1 2026: Southeast Asian startup funding hits $7.25B but rests on one deal

The "Southeast Asia Startup Funding: Half Year 2026" report from Kickstart Ventures and DealStreetAsia, released this week, records $7.25 billion raised across 217 equity deals in the first half of 2026, up from $3.5 billion in H2 2025. Most of the increase came from one round: the $4.5 billion Series C for Singapore data-centre company DayOne. Excluding DayOne, regional funding fell 21% half-on-half to $2.75 billion. Transaction count fell 7%, to its lowest since at least 2018.

Singapore drew $6.65 billion across 145 deals, nearly 92% of total regional equity funding; even excluding DayOne it still commanded 78%. The report also notes a firmer macro backdrop: developing Southeast Asia is expected to grow about 4.6% in 2026, with technology exports and data-centre investment supporting Malaysia, Thailand and Vietnam. Even so, regional startups remain dependent on cross-border capital that is sensitive to U.S. monetary conditions.

Two numbers deserve attention. First, 92% of regional equity capital sits in Singapore: Vietnamese founders raising a regional round will face the entity question anyway, so prepare a Singapore holding structure before Series A rather than waiting for a fund to demand it, since converting mid-process burns weeks and slows the close. Second, the report explicitly names technology exports and data-centre investment as supports for Vietnam: that is a concrete sector pointer for angels — software and services around the data-centre supply chain (power, cooling, connectivity, operations, operational safety), software for export factories, cross-border logistics. On timing: with regional deal count at its lowest since at least 2018, local seed rounds face less price competition, but the gap from seed to Series A will be longer — angel checks should go to companies with real revenue that can survive 12 months without another round.
