The short version

  • Each has a real cost: Marqeta you still need a sponsor bank and a BIN, so the timeline and compliance burden of launching are set by a bank you must separately court and satisfy.; Skyflow reported contracts near 195,000 US dollars a year with a platform fee before usage put this out of reach of early stage companies, which are precisely the ones whose architecture is still cheap to change.
  • They diverge on capability: Marqeta covers Just-in-time funding, Skyflow covers Tokenised storage.
  • 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.

Marqeta

  • You still need a sponsor bank and a BIN, so the timeline and compliance burden of launching are set by a bank you must separately court and satisfy.
  • Pricing carries minimum monthly platform commitments, so a programme with modest card volume pays for capacity it never uses.
  • Programme revenue depends heavily on interchange, which means regulated debit interchange caps and European interchange caps materially change the business case by market.
  • Disputes, chargebacks and fraud losses sit with the programme, and teams that assumed the processor absorbed them discover a real operations headcount requirement.
  • Just-in-time funding makes your own authorisation endpoint a hard availability dependency; if it is slow or down, cards decline at the point of sale.

Skyflow

  • Reported contracts near 195,000 US dollars a year with a platform fee before usage put this out of reach of early stage companies, which are precisely the ones whose architecture is still cheap to change.
  • Every read of a protected field becomes a network call to a third party, so latency and an external availability dependency enter paths that were previously local database reads, and outage planning has to account for a vendor you do not control.
  • Analytics and joins on vaulted data are constrained; work that was a simple SQL join now happens through secure functions or on tokens, and data teams routinely discover this after the engineering team has committed.
  • Unwinding the vault later is a rewrite rather than a migration because tokens are threaded through every service, so the switching cost climbs steadily and the negotiating position at renewal weakens with each release.
  • Scope reduction is an architectural claim your own assessor must accept, so the audit saving is real only if the implementation genuinely keeps sensitive values off your systems, and partial implementations that leave a cache or a log line in place deliver the cost without the benefit.

Answered from the vendors’ own pages

Marqeta: Do I need a sponsor bank?

Yes. Marqeta is an issuer processor, not a bank. Card programmes run on a sponsor bank BIN, and that bank approves and supervises your programme.

Skyflow: Does Skyflow really take my systems out of PCI scope?

It can, if card data never touches your infrastructure and the detokenisation happens at the boundary. Your QSA has to agree the design, so validate the architecture with your assessor before signing.

Marqeta: How does the pricing really work?

A minimum monthly platform fee plus per-transaction and per-active-card charges, offset by a negotiated share of interchange. The interchange split is the substance of the deal.

Skyflow: What does it cost?

Nothing is published. Reported annual contracts sit around 195,000 US dollars, built from a platform fee plus usage by data subject count and additional charges per data residency region.

Marqeta: What is just-in-time funding?

Marqeta calls your endpoint at authorisation so you decide and fund each transaction, rather than pre-loading balances onto cards.

Skyflow: How does it help with data localisation?

Records can be pinned to a specified region, so an Indian or EU residency requirement is met by the vault rather than by you running regional databases and operations teams.

Skyflow: Can I still run analytics on vaulted data?

Partly. Aggregates and comparisons are supported through polymorphic encryption and secure functions, but arbitrary joins against other datasets are harder than they were, and this is the most common late surprise.
