“Can a YC-backed open finance API win the Southeast Asian underbanked data layer before regional incumbents and bank-led aggregators close the window?”
Finantier launched in 2020 as an open finance infrastructure startup serving Indonesia and Southeast Asia, offering account aggregation, identity/income verification, transactional data verification, and payment initiation through a single API. Backed by Y Combinator (W21) and targeting the region's underbanked, it positioned itself as the SEA equivalent of Plaid/Tink. PitchBook now lists the company as Out of Business — the open finance category in Indonesia consolidated around larger players (Brick, Brankas, Ayoconnect), and Finantier did not survive the shakeout.
