Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Ozone API

  • It provides the API layer, not the core connectivity, so the bulk of the project is still integrating your own core banking systems and that cost is not in the licence.
  • Value is driven by regulatory obligation, so an institution not under a mandate struggles to build a business case for the spend.
  • It is a small UK vendor selling to large regulated institutions, which raises procurement and vendor viability questions during bank due diligence.
  • Premium API monetisation is a genuine capability but few banks have found real demand, so revenue projections used to justify the purchase often do not materialise.
  • Standards evolve continuously and each revision means a change programme in your own systems, even where Ozone absorbs the specification work at the API edge.

Swan

  • Its regulatory base and strongest local account coverage are French and European, so companies needing US, UK-post-Brexit-specific, or broader global banking-as-a-service need an additional provider.
  • Pricing is described only philosophically (usage-based, no big setup fee) rather than published as an actual rate card, so a company still needs a sales conversation to get real numbers.
  • Embedding banking features into a product is a substantial compliance and design undertaking regardless of the vendor, and Swan handling the licence does not remove a platform's own KYC, AML and customer support obligations for the accounts it offers.
  • As a comparatively young, single-country-licensed e-money institution, its balance sheet and regulatory standing carry more concentration risk than a banking-as-a-service offering backed by an established, multi-jurisdiction bank.
  • Local account depth is explicitly limited to France, Germany and Spain, so a platform needing native local accounts in other European countries may find coverage thinner than expected.
