Main Capital Partners announces strategic partnership with Norwegian enterprise fintech platform Aritma

Stockholm, May 1, 2025 – Main Capital Partners (“Main”) is acquiring a majority stake in Aritma, a fast-growing Norwegian fintech offering cloud-based solutions for payments, reconciliation, and bookkeeping automation. This Main Foundation II investment further strengthens Main’s presence in the Nordic enterprise software landscape. Through the partnership, Main will support Aritma’s continued expansion of its product suite, international growth, and selective strategic acquisitions.

Founded in 1990 and headquartered in Bergen, Aritma is a key enabler for ERP vendors, accounting platforms, and financial institutions. Its modular, API-first platform connects ERP systems with the banking ecosystem, automating essential financial workflows such as payments, reconciliation, and data validation. Today, the company serves approximately 900 customers, including leading ERP providers, supported by a modern tech stack and scalable architecture suited for high-volume, regulated use cases.

Attractive market dynamics and international scalability
The primary motivations behind the strategic partnership with Aritma are its strong product-market fit, deep workflow integration, and high scalability. In an increasingly regulated and digitized financial environment, Aritma enables customers to automate critical financial operations while ensuring compliance with evolving standards. This backdrop, combined with structural drivers such as growing regulatory complexity, rising demand for real-time financial data, and the shift to cloud-based infrastructure, creates a favorable environment for Aritma’s modern platform and extensive bank integration network.

The company is ready to accelerate international expansion, building on its Nordic footprint and growing embedded partner model. Leveraging Main’s strategic expertise and track record in supporting cross-border growth, both organically and through acquisitions, Aritma aims to become a leading European platform for payment and reconciliation automation. The experienced management team will remain closely involved post-closing to help drive the next phase of growth alongside Main.

Thor Kristian Seth, CEO of Aritma: “We are very proud to announce our partnership with Main Capital Partners, a collaboration that marks a key milestone in Aritma’s history. Main’s proven track record in building and scaling software companies fits perfectly with our ambitions. Together, we are committed to accelerating Aritma’s growth, expanding into new markets, and strengthening our position as a trusted enabler of financial automation in Europe”

Wessel Ploegmakers, Partner at Main Capital Partners: “We are excited to partner with the Aritma team as they continue building one of the most compelling platforms in financial workflow automation. Aritma’s strong market position, modern architecture, and mission-critical offering make it a great fit with our investment strategy. Together, we look forward to accelerating their international growth and supporting the next phase of their journey”
