Mobile banking that earns daily engagement

Most banking apps are used once a month to check a balance and 2 transfers. We design apps that become daily financial companions — with conversational process and service flows so intuitive they replace the branch visit entirely.

  • Personalised financial health dashboards with actionable recommendations
  • Instant payments, SEPA, and P2P transfers with biometric authentication
  • In-app product origination — loans, cards, savings — without branch referral
  • Push notification strategy to drive high-value feature discovery
Onboarding completion rate improvement
60%

Reduction in onboarding drop-off achieved through intelligent journey redesign and automated KYC — cutting abandonment from 45% to under 18%.

Onboarding that closes deals, not tabs

Digital onboarding abandonment above 40% is still the norm for European banks. We eliminate the friction that causes drop-offs — intelligent form logic, real-time KYC, pre-filled data, and instant decisioning that turns applicants into customers in minutes.

  • KYC/KYB automation with biometric ID verification, e-IDas and liveness checks
  • Pre-fill from open banking data to minimise user input effort
  • Risk-based adaptive flows — simpler journeys for lower-risk profiles
  • Real-time compliance checks with automated AML screening

Open banking as a growth engine

Open banking is still treated as a compliance obligation by most banks. We help forward-thinking institutions turn it into a product advantage — aggregating accounts, enabling embedded finance, and building API-first products better than your competitors.

  • PSD2-compliant API infrastructure with developer portal and sandbox
  • Account aggregation for personal finance management features
  • Embedded finance marketplace — payments, BNPL, insurance, investments at point of need
  • Revenue-sharing commercial models for third-party API monetisation
