Challenger Bank Banco CTT Launches New Partner Portal to Fuel Mortgage Lending Growth

Portuguese challenger bank Banco CTT needed to overhaul a largely manual mortgage origination process that was slowing approvals and frustrating its network of about 500 partner brokers. The bank wanted to give partners autonomy, real‑time tracking and a first‑to‑market digital experience to improve customer service and win market share.

Using the OutSystems low‑code platform with implementation partner askblue, Banco CTT launched a partner portal in six months that lets partners submit applications, run simulations, receive automated status alerts and integrates with back‑office systems. Seven months after go‑live the bank reported higher partner‑sourced originations, a 30% increase in loan value, a fourfold productivity gain, a reduction in processing headcount from six to two, and 2,500 users on the platform.
