Summary

Fintech companies like Starling, Bunq, and Bitpanda are increasingly adopting an "as-a-service" (aaS) model, transforming their proprietary infrastructure into new business offerings. This strategic pivot, reminiscent of Amazon's AWS launch in 2006, allows these firms to generate significant new revenue streams by selling their core technology, such as payment processing, card issuing, and compliance solutions, to other businesses. Starling launched its Banking-as-a-Service product, Engine, in 2024, while Bunq and Bitpanda have also expanded into B2B infrastructure. Motivations include capitalizing on the embedded finance trend, addressing market demand for robust financial tools, and diversifying revenue beyond consumer-facing products. Challenges involve navigating complex regulatory landscapes and building dedicated B2B sales and support operations.

Key takeaway

For CTOs and executives evaluating growth strategies, recognize the significant opportunity in productizing your core fintech infrastructure. Your internal payment processing, card issuing, or compliance systems can become valuable "as-a-service" offerings, diversifying revenue and tapping into the embedded finance market. Be prepared to invest in a dedicated B2B sales engine and navigate complex regulatory requirements to succeed in this pivot.
