Primer, a London-based funds infrastructure startup, as we speak introduced a €86.2 million ($100 million) Collection C funding spherical to speed up its funding in AI for funds and finance groups and to drive its growth within the US.
The spherical was led by Sofina, with participation from Peak XV Companions and continued backing from all current traders, together with Balderton, Accel, ICONIQ, Tencent, and Speedinvest. It has raised a complete of €146.6 million ($170 million).
“Within the subsequent few years, each fee resolution in a big enterprise will likely be initiated, optimised, or audited by AI. That shift is already underway. The query is whether or not the information these programs run on is full as a result of while you deploy brokers throughout fragmented information, they don’t simply underperform, they make the mistaken resolution. That’s why the subsequent period of funds can solely be constructed on full, contextual intelligence. And that’s what Primer delivers,” mentioned Gabriel Le Roux, CEO and co-founder of Primer.
Based in 2020 by former leaders of Braintree and PayPal, Primer provides finance and funds groups the visibility and management to scale back complexity, enhance efficiency, and seize extra income, all from a single platform.
In line with the corporate, AI is barely nearly as good as the information it runs on. In funds, Primer states that information is never full. Many organisations run funds via fragmented processors, acquirers, and fraud instruments, with no single system offering an entire view.
As funds and finance groups incorporate AI, this fragmentation turns into a significant vulnerability, doubtlessly resulting in widespread incorrect selections.
Primer was based on the premise that funds wanted a single, unified infrastructure layer earlier than they might profit from the intelligence constructed on prime. At present, the platform covers a service provider’s total funds lifecycle, from checkout to payout, recording over 400 information factors per transaction and dealing with greater than 95% of buyer fee quantity on common.

Jean-François Burguet, Head of Digital at Sofina, mentioned, “Funds are reaching a structural turning level, with retailers consolidating onto unified infrastructure and AI transferring to the center of each transaction resolution. Gabriel and the workforce have spent the previous six years constructing the platform finest suited to that future, incomes the belief of a few of the world’s most demanding retailers. We’re privileged to companion with them for the long run as they scale within the US and globally.”
Following the increase, Primer is now doubling down on its funding in AI capabilities, together with the growth of its proprietary AI agent, Primer Companion. Launched final yr, Primer Companion helps retailers reply complicated fee queries and floor contextual insights.
Primer states that it’ll now scale its capabilities to run experiments, optimise efficiency, and function autonomously inside merchant-defined parameters, transferring from a instrument that informs selections to at least one that executes them.
“We don’t need retailers chasing issues or lacking alternatives. With full context throughout each fee, Primer Companion can act on their behalf, understanding what’s taking place, why, and what to do subsequent.” Le Roux added.
Primer has already established traction within the US, which now accounts for round a fifth of income, with ARR doubling year-on-year. The corporate plans to develop US income to greater than a 3rd of its enterprise by 2028 and can rent as much as 50 roles within the area to help that growth.
