The short version

  • Each has a real cost: Akoya coverage reaches several thousand institutions but does not match aggregators that can still scrape, so applications needing the long tail of small credit unions will run a second data provider alongside it.; Solaris baFin appointed a special representative in 2022 and extended the mandate in July 2024, so a partner is joining a bank under active supervisory monitoring, with slower approvals and heavier compliance demands as a direct consequence.
  • They diverge on capability: Akoya covers FDX standard APIs, Solaris covers German banking licence.
  • 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.

Akoya

  • Coverage reaches several thousand institutions but does not match aggregators that can still scrape, so applications needing the long tail of small credit unions will run a second data provider alongside it.
  • The network is owned by large banks, so roadmap and coverage priorities reflect owner interests rather than those of the fintechs consuming the data, and a recipient has no leverage over which institutions are added next.
  • Data availability is decided institution by institution, meaning a bank may expose balances but not transactions or investments, and recipients must verify field-level coverage per institution rather than assume the FDX model is fully populated.
  • Pricing is unpublished and usage based, which makes it difficult to compare against aggregator pricing during a build-versus-buy decision and forces a sales cycle before you can model cost.
  • The token model requires the institution to have implemented its side, so newly onboarded institutions arrive on the institution timetable, not yours, and a launch dependent on a specific bank can slip badly.

Solaris

  • BaFin appointed a special representative in 2022 and extended the mandate in July 2024, so a partner is joining a bank under active supervisory monitoring, with slower approvals and heavier compliance demands as a direct consequence.
  • BaFin fined Solaris EUR 6.5 million in March 2024 for systematically late suspicious activity reports and EUR 500,000 for breaching large exposure limits between January 2022 and March 2024, which is a track record a partner inherits reputationally.
  • Solaris has previously needed BaFin approval before onboarding new corporate clients, which can turn a commercial decision to launch into a regulatory timetable outside your control.
  • The 2024 restructuring involved job cuts and the closure of parts of a business unit, so product lines a partner depends on may not have the engineering behind them that the sales process implies.
  • SBI Holdings acquired majority control in 2025, so strategic direction now sits with a Japanese financial group whose priorities for the European business may differ from the roadmap you were sold.

Answered from the vendors’ own pages

Akoya: Who owns Akoya?

A group of large US banks. It was spun out of Fidelity, which is why Fidelity data access runs through it.

Solaris: Does Solaris have a real banking licence?

Yes. Solaris SE is a German credit institution, which is why it can offer deposits and lending, unlike e-money based competitors.

Akoya: Is Akoya screen scraping?

No. It uses FDX standard APIs with OpenID Connect tokens, so credentials are never shared with or stored by the data recipient.

Solaris: Is the BaFin action still live?

The special representative appointed in 2022 had the mandate extended in July 2024, and fines were issued in March 2024. Treat supervisory oversight as an active condition in your diligence.

Akoya: Can we use Akoya alone instead of an aggregator?

Usually not. Its investment and large-institution coverage is excellent, but the long tail of smaller institutions is thinner, so most teams run both.

Solaris: Who owns Solaris now?

SBI Holdings of Japan agreed in December 2024 and January 2025 to take a majority stake of over seventy per cent for around EUR 100 million.

Akoya: Does it help with CFPB section 1033?

It is designed around it, providing tokenised permissioned access and consumer revocation rather than credential sharing.
