Primer, a London-based payment startup, has announced a €86.2 million Series C funding round to expand its AI payments and finance platform. The capital will also support its market development in the US, where the company plans to grow revenue to more than a third of total revenue by 2028, supported by plans to hire up to 50 roles in the region.

Primer is a financial technology company that provides a unified payment infrastructure, enabling companies to optimize and control every step of the payment journey.

The platform offers complete visibility and control across the entire payment operations system, integrating payment orchestration, reconciliation, security, FX, and financial operations services into a single open layer.

The company was built to solve a persistent problem: businesses having to rely on multiple fragmented providers and tools throughout the payment journey. Currently, the platform covers the merchant’s entire payment lifecycle, recording over 400 data points per transaction and handling more than 95% of customer payment volume on average.

The investment round was led by Sofina and Peak XV Partners, and backed by existing investors, including Balderton, Accel, ICONIQ, Tencent, and Speedinvest. With this new investment, the company has raised a total of €146.6 million, with platform adoption spanning more than 30 countries.
