Is Capital On Tap accepted by AWS, GCP and OpenAI?

Yes. Capital On Tap issues Visa Business cards which are accepted globally by all major cloud and SaaS providers.

Will my AWS spike trigger a card decline?

Capital On Tap is built for SMBs with variable spend — sudden large transactions are normal. If a transaction exceeds your available limit, request a temporary increase via support before peak usage.

Better to use Capital On Tap or a corporate card like Brex / Ramp?

Brex and Ramp are not currently available to UK-based companies. Capital On Tap is the closest UK equivalent with rewards and instant virtual cards. Many UK SaaS startups also use Mercury for banking + Capital On Tap for spend.
