From a Provider-Dependent Stack to a Scalable Financial Platform

Kleos reached a point where extending the existing platform created more constraints than opportunities. The next stage of growth required a fundamentally different operating model — not a technology refresh, but a business transformation.

Business problem

Kleos wanted to evolve from a provider-dependent fintech application into a platform capable of supporting long-term product expansion.

Target operating model

  • Self-custody wallets
  • Fiat banking infrastructure
  • Card payments
  • Stablecoin operations
  • Yield products
  • Tokenized investment mechanics

What made this difficult

Strategic

Core customer experiences and financial operations depended on infrastructure decisions made earlier in the product lifecycle.

Operational

Wallet custody, banking operations, payment services, and investment products operated across separate environments and provider models.

Product

Introducing new services required disproportionate implementation effort because changes had to be coordinated across disconnected systems.

Economic

Scaling the current architecture increased integration costs and created long-term migration risk.

The challenge was not delivering new functionality. The challenge was building an operating model capable of supporting future functionality.

The cost of scaling the existing model

If Kleos continued to scale the existing setup, the likely outcomes included:

  • Slower product releases
  • Increasing provider dependency
  • Duplicated operational processes
  • Growing infrastructure costs
  • Reduced speed of introducing new financial products
  • Expensive future migrations
  • Limited ownership over customer experience
  • Higher compliance and operational overhead

Over time, the business risk would shift from technical debt to strategic debt.

Existing options and trade-offs

OptionWhy companies choose itWhere it breaks
Continue with existing infrastructureMinimal disruption and lower short-term investmentProduct expansion remains constrained
Replace only custody infrastructureFaster implementationDoes not solve fragmentation
Build a completely custom platformMaximum ownershipLong delivery cycle and high execution cost
Add providers incrementallyShort-term flexibilityCreates operational complexity
Create a unified infrastructure foundationEnables long-term product flexibilityRequires stronger architecture decisions upfront

Kleos evaluated the trade-off between short-term delivery speed and long-term product ownership. The selected direction prioritized extensibility and infrastructure control rather than short-term optimization.

What the solution provides

The resulting platform foundation enables a unified operating layer supporting traditional and digital financial services.

Unified financial infrastructure

One operational layer supporting traditional and digital financial services.

Banking and payment operations

Infrastructure supporting Euro IBAN accounts and SEPA/SWIFT flows.

Global payment experiences

Visa card capabilities integrated into the product ecosystem.

Digital asset ownership

Migration toward non-custodial wallets using Web3Auth with MPC and Account Abstraction capabilities.

Stablecoin infrastructure

Support for USDC on Ethereum.

Investment and yield capabilities

Tokenized yield vaults and portfolio execution through on-chain operations.

Smart-contract orchestration

A programmable layer connecting investment, wallet, and payment experiences.

Operational management

Administrative and back-office capabilities supporting control and visibility.

05

Business outcomes

With this approach, Kleos can compound product development over time — not only lower operational friction, but a stronger ability to scale.

Launch and expand faster

New financial capabilities can be introduced without rebuilding infrastructure layers.

Reduce infrastructure dependency

Product evolution becomes less constrained by individual vendors.

Improve unit economics

Reusable infrastructure lowers marginal delivery effort for future services.

Support additional product lines

The platform becomes capable of supporting future banking, payment, wallet, and investment scenarios.

Increase strategic flexibility

Business decisions are no longer blocked by architectural limitations.

Prepare for future regulatory evolution

Infrastructure decisions support a more scalable compliance model.
