PSA Solutions and Norvestor partner to build European Legal Tech leader

Norvestor Nova I SCSp (“Norvestor”) has signed an agreement to acquire the majority of the shares in PSA Solutions AS ("PSA" or "the Company"), a Norwegian legal tech partner for top-tier law firms and corporate legal departments.

Oslo, 5 May 2025

PSA Solutions, a leading digitalisation partner for law firms and corporate legal departments across Northern Europe, has been acquired by Norvestor, marking a strategic move to build a dominant force in the rapidly evolving European legal technology market.

With the legal tech sector experiencing unprecedented momentum—propelled by AI adoption, automation, and increasing demands for operational efficiency—this partnership aims to capitalise on growth opportunities across the Nordics and the rest of Europe. PSA’s strong position in the Nordics, combined with Norvestor’s experience in scaling high-potential companies, sets the stage for such continued expansion in key markets.

PSA develops, offers, and implements mission-critical proprietary and third-party Software as a Service (“SaaS”) solutions for top-tier law firms, corporate legal departments, and other professional services organisations. PSA is recognised as one of Europe’s leading iManage partners, with a long-standing track record of delivering document and knowledge management solutions to law firms, corporate legal teams, and public sector organisations. At the core of its offering is Custodian, PSA’s proprietary flagship Integration-as-a-Service platform, which enables secure, scalable integration between iManage, ERP/PMS systems, and other applications and services—empowering legal teams to streamline operations and accelerate digital transformation.

The acquisition ensures PSA’s existing customers gain an even stronger and more capable strategic partner—with greater capacity for innovation, extended service coverage, and long-term investment in the technologies and platforms that matter most to legal firms and corporate legal departments.

“On behalf of PSA, I would like to extend my gratitude to all our dedicated employees, whose hard work has been instrumental in our success, and to our valued customers, whose support and trust have been pivotal in our journey. I am delighted to have Norvestor joining us as a new majority owner-partner, as they have demonstrated a clear understanding of our products, markets and customers. We now look forward to utilising Norvestor’s expertise and experience in developing Nordic technology companies to accelerate PSA’s growth in existing and new markets”, says Martin Flatsetø, Co-Founder and CEO of PSA.

“PSA has demonstrated deep domain expertise, a highly scalable platform in Custodian, and a strong client base in a dynamic sector we know well,” says  Georg Enderlein, Norvestor Partner and incoming Chair at PSA. “We are excited to back their growth ambitions and support the team in building a true European legal tech leader.”

The partnership reinforces the growing demand for European-led legal tech solutions and aims to establish a significant presence across key markets—supporting law firms and corporate legal departments in their digital transformation journeys.

Following the acquisition, Norvestor will become the largest shareholder in PSA, followed by PSA's management and key employees. All the previous employee-owners have reinvested into the new partnership.

The transaction is in line with Norvestor’s focus on acquiring and scaling outstanding mid-market companies in the Nordic region. The transaction was closed on 30 April 2025.
