The short version
- Each has a real cost: Aiia it is now part of Mastercard rather than an independent company, so a business specifically wanting to avoid card network dependency in its banking infrastructure no longer gets that separation by choosing Aiia.; Astra push-to-card costs materially more per transaction than ACH, so a platform that switches all payouts to instant sees payment costs rise sharply, and the usual answer of charging the recipient for speed only works where recipients will pay.
- They diverge on capability: Aiia covers Bank account data access, Astra covers Instant disbursements.
- Prices and features above were last checked on 1 September 2026.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Aiia
- It is now part of Mastercard rather than an independent company, so a business specifically wanting to avoid card network dependency in its banking infrastructure no longer gets that separation by choosing Aiia.
- Pricing is not published and requires engaging Mastercard's open finance sales process, which can be a heavier sales motion than dealing with a smaller independent open banking provider.
- Its strongest bank coverage remains concentrated in the Nordics and Northern Europe, so companies needing dense coverage in Southern or Eastern Europe should verify current bank connectivity before committing.
- Brand confusion is real: developer documentation, login portals and older case studies still reference "Aiia" while newer Mastercard material refers to "Mastercard Open Banking," and a company researching either name in isolation may miss half the relevant material.
- As with any open banking platform, reliability still depends on the consistency of the underlying banks' own APIs, which is a systemic industry issue rather than something Aiia specifically controls.
Astra
- Push-to-card costs materially more per transaction than ACH, so a platform that switches all payouts to instant sees payment costs rise sharply, and the usual answer of charging the recipient for speed only works where recipients will pay.
- Original Credit Transaction support is not universal across card issuers, so a proportion of payouts fall back to slower rails and you must build and explain a two speed experience rather than promising instant to everyone.
- The programme depends on Cross River Bank as sponsor, a bank with concentrated fintech exposure and a documented regulatory history, so a single supervisory action on that institution is a direct operational risk to your payouts.
- Nothing is published on pricing, and per transaction economics vary by rail and volume, so small platforms cannot estimate cost before a sales conversation and have limited leverage in it.
- FedNow reach still depends on the recipient bank participating, so instant account-to-account is not available to every recipient and the routing logic has to degrade gracefully, which is more integration work than the single API framing suggests.

Answered from the vendors’ own pages
Aiia: Is Aiia still an independent company?
No, it was acquired by Mastercard in 2021 and now operates as part of Mastercard Open Finance Solutions, referenced as Aiia Enterprise.
Astra: Who is the sponsor bank?
Cross River Bank. All banking and payment services run through that relationship, so the bank should be part of your diligence rather than an implementation detail.
Aiia: Does the Aiia brand still exist?
Yes, in developer documentation and login portals, but the company behind it is Mastercard.
Astra: Do I have to prefund payouts?
Not necessarily. Astra offers a net debit arrangement where disbursements settle against a reserve rather than a permanently funded float account, which is the main working capital argument for the product.
Aiia: Which banks does it cover?
Around 3,000 European banks, with strongest coverage in the Nordics and Northern Europe.
Astra: Is every payout instant?
No. Push-to-card requires the recipient card issuer to support Original Credit Transactions, and FedNow requires the recipient bank to participate. The rest fall back to ACH.
Astra: What does it cost?
Nothing is published. Pricing is per transaction and varies by rail and volume, and card rails cost considerably more than ACH.
