Slash
Fintech · FDIC via partner bankVertical banking for online businesses — friendly to web3, ecommerce, agencies.
Official siteBusiness banking takes US entities (LLC/LP/C/S) and accepts non-US owners — owners may live abroad, and the operating address just proves your real place of business (Slash support confirms it can be overseas). Web3/crypto-friendly, unlike Mercury. ~500 virtual cards for heavy card-splitting. Foreign companies with no US entity use its separate Global USD account.

What the complaints are actually aboutUser reviews
The percentages below are shares of this bank's own negative reviews — not a rating, and not a probability of it happening to you. We pull only 1-2 star reviews, so the sample is larger than it looks; the composition of the complaints is what's comparable across banks.

Last 12 months: 1.3 negative reviews/month (13 total) | lifetime 19 of 413 reviews = 5%
Themes computed over 18 negative reviews, 2022-02-17 → 2026-07-24 (1618 days) | captured 2026-08-04
These 18 are every negative review Slash has ever received, and its 5% lifetime negative rate is the lowest here. They point the same way with unusual consistency: closures and "no reason given" each at 39%, rising to 46% and 54% across the 13 from the last 12 months. The recurring scene is a communication breakdown during compliance review — support says it can't see the compliance queue, compliance doesn't talk to customers, the account just sits frozen. Slash explicitly accepts non-SSN foreign founders and crypto-adjacent business, and a higher-risk base mechanically produces more reviews — see the cross-bank comparison for how that trade-off looks next to the others.
Method: public Trustpilot reviews, aggregate counts only — no review text is reproduced. Lifetime negative counts come from Trustpilot's own star distribution, not from a sample. Themes are keyword-matched, so one review can match several and the percentages don't sum to 100%.
