The challenge with innovation inside large institutions is rarely about ideas. It's about structure. Banks operate with risk controls, compliance layers, and approval chains designed for stability — none of which are optimised for fast experimentation. The skunkworks model sidesteps that by creating a separate operating environment with its own rules, team, and timeline. We worked directly with Santander's Nordic leadership to define what the team would be, who would staff it, and what success would look like. The objective was dual-track from the start: ship something real, and build a replicable process. The first track provides proof of concept and momentum. The second track is what makes the investment durable — a documented way of working that Santander could use for subsequent innovation cycles without external support. The Strm.finance concept emerged from this process: a financial platform that combines a digital interface with physical sensor data, giving users a different kind of visibility into their financial behaviour. The concept was chosen because it represented a genuine departure from existing Santander products — which was the point.
