So I built the boring version. 19 providers × 8 countries, 152 cells, one of four states per cell, each backed by a verbatim quote from the provider's own terms or help centre:

explicit_accept (26) — they say in writing that they take founders resident there

explicit_restrict (61) — they say in writing that they do not

no_published_restriction (26) — I read their published restrictions and this country is not on them

unknown (39) — no published source answers it

That last state is 26% of the grid and it is the part I care most about. The failure mode in this category is treating silence as a yes. A provider not listing your country is not the same as a provider accepting your country, and almost every roundup I have read flattens those two into one green checkmark. Splitting them is most of the value here.

Two things that surprised me while building it.

15 of the 19 are not banks. They are fintechs sitting on a partner bank. That changes what "FDIC insured" means for your balance and who actually decides your account gets closed, and it is nearly invisible in the marketing. One provider's own pages put checking-account coverage at $250,000 through its partner bank while a separate savings product reaches $75M through a deposit network — I had the larger number attached to the wrong product until a re-read caught it.

Claims rot fast, and a lot of them are wrong at publication rather than later. 268 claims were mined; 239 survived a refute-first pass where the goal was to kill each one. The rest were wrong when written. That is why every cell carries its quote and its source URL: so you can check me rather than trust me.

Disclosure, up front: the parent site is an affiliate-funded comparison hub, and some providers in this dataset pay me if a reader signs up through a link elsewhere on the site. The dataset itself is CC-BY 4.0, downloadable whole as CSV and JSON with no signup, and archived on Zenodo with a DOI (10.5281/zenodo.21336392) — so it stays checkable even if I later change my mind about something, and you can fork it if you think I am wrong. Restriction states were assigned from provider documents before any commercial relationship was considered, and the two states that look worst for a paying provider (explicit_restrict, unknown) are the two most common in the grid.

Known limits: 8 countries, chosen because they are where my readers actually are, not because they are the biggest. Two later dimensions (international receiving, card issuance) are single-pass research and flagged in the data as a lower evidence tier — they have not been through the refute-first pass yet. Last verified 2026-08-02; re-verified quarterly.

Happy to be told a cell is wrong. That is the useful outcome.
