Primer has raised US$100 million in Series C funding to expand its AI payments platform and grow its US business.
The round was led by Sofina, with participation from Peak XV Partners and existing investors Balderton, Accel, ICONIQ, Tencent and Speedinvest.
Primer will use the funds to develop AI tools for payments and finance teams, including Primer Companion, its AI agent for merchants.
Founded in 2020, Primer helps merchants manage payments across processors, acquirers, fraud tools and payment methods.
Its platform captures more than 400 data points per transaction, manages more than 95% of customer payment volume on average and processes billions of transactions annually for businesses including GetYourGuide, Dialpad and Printful.
Fragmented payment data can affect how AI tools support payment decisions.

“In the next few years, every payment decision in a large business will be initiated, optimized or audited by AI. That shift is already underway.
The question is whether the data those systems run on is complete because when you deploy agents across fragmented data, they don’t just underperform, they make the wrong decision. That’s why the next era of payments can only be built on complete, contextual intelligence.”
said Gabriel Le Roux, CEO and co-founder of Primer.
Primer Companion was launched in 2025 to answer payment queries and surface insights from merchant payment data.
Primer plans to develop the tool further so it can run experiments, optimise performance and operate within merchant-defined parameters.
The US accounts for around a fifth of Primer’s revenue, with annual recurring revenue in the region doubling year-on-year.
Primer aims to grow US revenue to more than a third of total revenue by 2028 and hire up to 50 people in the region.
