Startup Researcher has comprehensively mapped eight mergers involving startups and scaleups linked to South or Southeast Asia that reached an announcement, completion, or integration milestone between January 1 and September 30, 2026. Three were cross-border mergers. Integra Micro Software Services (IMSS) and OpenTurf Technologies announced their merger on September 30, but it had not closed by that date.

Methodology
This review covers merger milestones involving startups and scaleups associated with South or Southeast Asia between January 1 and September 30, 2026. Qualifying milestones include a newly announced merger or amalgamation and the completion, consolidation, or operational implementation of a previously announced combination during the period. Announced transactions still pending at the cutoff are included, while mergers withdrawn or canceled by September 30 are excluded.
At least one party had to be primarily associated with a South or Southeast Asian startup ecosystem through its founding history, early operations, principal markets, or recognized ecosystem identity. Transactions between two startups could qualify when only one party had its primary entrepreneurial roots in the region. The geographic classification therefore reflects the businesses' entrepreneurial ecosystems rather than exchange listings or legal headquarters alone.
A qualifying startup or scaleup is an independently founded, innovation-driven business built around a scalable product, technology, platform, or business model. Conventional small businesses, consultancies, agencies, established financial institutions, state-owned businesses, and mature corporate groups without a credible startup or scaleup identity are outside the stated scope. A participating company's status is considered in the context of its business model and recognized ecosystem connection rather than its age alone.
The review focuses on transactions publicly characterized as mergers or amalgamations by the parties involved. Acquisitions, joint ventures, minority stake purchases, standalone asset purchases, internal restructurings, and SPAC transactions primarily intended to take businesses public are excluded. A combination primarily presented as an acquisition is not counted as a merger merely because an acquired company is subsequently absorbed through legal implementation.
The parties' explicit characterization of a combination as a merger is retained when the mechanics involve shares, subsidiaries, or holding-company arrangements. Monetary amounts are treated as merger values only when credible public reporting specifically identifies them as consideration for the merger itself. Revenue, insurance premium books, fundraising, company valuations, capital injections, and other operating measures are not substituted for transaction values.
