Primer has officially announced the successful closing of a $100 million Series C funding round as the company accelerates its mission to become the AI-native intelligence layer powering the future of global payments and treasury operations.

The investment round was led by Sofina, with participation from Peak XV Partners and all existing investors. According to the company, the fresh capital will primarily support aggressive product development initiatives and geographic expansion, with a major strategic focus placed on scaling operations throughout the United States. Founded in 2020 by former Braintree executives, Primer has positioned itself as a unified payments infrastructure platform designed to solve one of the largest emerging operational challenges facing enterprise finance teams: fragmented financial data in the AI era.
Addressing the โfragmentation trapโ limiting enterprise AI adoption
As financial institutions and enterprise merchants increasingly attempt to integrate artificial intelligence into operational decision-making, many are discovering that their data environments remain deeply fragmented across payment processors, fraud platforms, ERP systems, acquirers, and treasury tools.
According to Primer, this fragmentation creates a critical structural problem where AI systems are forced to make decisions using incomplete datasets and disconnected transaction visibility. The company argues that this often leads to inefficient payment routing, hidden operational costs, poor fraud management decisions, and reduced margins. To solve this issue, Primer has built a unified infrastructure layer that sits across the entire payments lifecycle from checkout and payment orchestration to reconciliation and payouts. By centralizing these workflows into a single ecosystem, the platform creates what the company describes as a โsingle version of truthโ for enterprise financial operations. Rather than operating as another isolated payment tool, Primerโs strategy focuses on becoming the foundational intelligence layer that powers AI-driven financial decision-making across large enterprises.
AI Companion becomes the center of Primerโs platform strategy
At the core of Primerโs latest expansion is AI Companion, the companyโs proprietary AI agent built on top of a unified transaction intelligence engine. Because Primer sits across the full payment lifecycle, the platform captures more than 400 data points per transaction far exceeding the visibility available to most traditional payment providers and fragmented financial systems.
This enterprise-wide data context enables AI Companion to:
- identify anomalies and operational inefficiencies
- answer complex financial and payment-related queries
- optimize payment routing and performance
- execute automated operational experiments
- manage treasury workflows within predefined controls
Primer emphasized that the platform is designed not simply to provide AI-powered recommendations, but to evolve toward autonomous operational execution inside enterprise financial systems. The company is also extending these capabilities beyond payment acceptance into broader treasury and financial management operations, including:
- Global Accounts
- Reconciliation
- Costs Overview
- FX leakage analysis
- hidden fee optimization
By embedding intelligence directly into payment and treasury infrastructure, Primer aims to help enterprise finance teams move away from reactive operational management toward proactive, AI-assisted financial orchestration.
Aggressive U.S. expansion becomes a major strategic priority
A significant portion of the new funding will support Primerโs expansion throughout the United States, which has rapidly become one of the companyโs fastest-growing markets. According to Primer, the U.S. currently represents approximately 20% of total company revenue, while annual recurring revenue in the region has doubled year-over-year. The company expects the American market to account for more than one-third of its overall business by 2028.
To support this growth trajectory, Primer plans to significantly expand:
- sales operations
- engineering teams
- customer success divisions
- enterprise merchant partnerships
The company is specifically targeting large-scale enterprise organizations that continue struggling with fragmented legacy payment stacks and operational inefficiencies caused by disconnected vendor ecosystems. Primer believes future enterprise financial operations will increasingly require unified infrastructure capable of supporting AI systems with complete contextual visibility across all transaction and treasury activities.
Building network effects across the broader payments ecosystem
Beyond serving merchants directly, Primer is also expanding its broader infrastructure strategy through Primer for Partners, a platform initiative designed to allow Payment Service Providers (PSPs) and financial partners to build directly on top of Primerโs infrastructure stack. The objective is to create ecosystem-wide network effects where multiple payment providers, financial systems, and enterprise services can operate within a shared intelligence environment rather than functioning as isolated silos.
According to Primer Co-founder&CEO – Gabriel Le Roux , the future of payments will increasingly depend on unified intelligence rather than fragmented vendor relationships and disconnected operational tooling.
โThe next era of payments will be built on unified intelligence. The next era of payments will be built on Primer.โ
By positioning itself as the underlying intelligence and orchestration layer connecting fragmented payment ecosystems, Primer is betting that enterprises adopting unified AI-native infrastructure will ultimately outperform competitors still operating on legacy financial stacks.
