Fintech Power Play: Shares Acquires Société Générale's Treezor for BaaS Dominance

Shares has officially completed the acquisition of 100% of Treezor from Société Générale, a transaction confirmed by both companies on October 7, 2026. This strategic deal brings together two complementary entities, creating an enlarged group that possesses a comprehensive suite of regulatory licenses. These licenses now cover electronic money, payment services, investment services, and crypto-assets, all supervised by the esteemed French regulatory bodies, the ACPR (Autorité de Contrôle Prudentiel et de Résolution) and the AMF (Autorité des Marchés Financiers).

Benjamin Chemla, who is the chief executive and co-founder of Shares Group, will assume the leadership role for this newly combined entity. Treezor's operations will be managed by Cédric Cassini, with support from Julien Mortuaire. Although the precise transaction price was not publicly disclosed, the strategic value of this integration is significant for the European financial services landscape.

Treezor, established in 2016, has built a robust reputation as an authorized electronic money institution by the ACPR. Since its inception, it has processed an impressive transaction volume exceeding €145 billion and has issued over 8.5 million cards. The company holds principal memberships with both Mastercard and Visa, further enhancing its capabilities, and its regulatory passport extends its reach across 25 EU member states. Notably, Treezor already generates close to 70% of its revenue growth from outside France, maintaining on-the-ground operations in key European markets like Germany, Italy, and Spain.

Shares, founded in 2021, initially entered the market as a retail investing application. It subsequently broadened its regulated technology offerings to cater to wealth managers, financial institutions, and employee savings providers. Shares has successfully raised a total of $90 million in funding from prominent investors including Valar Ventures, Singular, Global Founders Capital, and Red Sea Ventures. The company employs approximately 150 individuals across its offices in France, the UK, and Poland. Shares Financial Assets holds an ACPR-authorized investment firm license and is registered as a crypto-asset service provider under both the ACPR and the AMF frameworks.

The combined group's ambitious vision is to deliver a modular, white-label infrastructure stack. This comprehensive offering will span the entire value chain of financial services, from current accounts and card issuance to savings products and sophisticated investment portfolios. These services will be delivered via API to a diverse clientele including fintechs, corporates, and established financial institutions. According to Benjamin Chemla, this integrated infrastructure is crucial for transforming financial services in Europe, by providing a unified solution that covers everything from basic accounts to complex investments.

This acquisition arrives at a pivotal moment for the European Banking-as-a-Service (BaaS) sector. The initial wave of BaaS providers primarily focused on accounts, cards, and SEPA payments. However, the commercial limitations of this model have become apparent, characterized by thin margins on commodity payment flows and increased regulatory scrutiny regarding client onboarding and AML controls. This pressure is compelling more forward-thinking players to either expand their product sets or consolidate capabilities with complementary businesses.

The strategy of combining payment infrastructure with investment and savings rails within a single regulatory perimeter is distinctive. Most BaaS providers typically opt for API integrations with wealthtech or savings platforms. Shares and Treezor are making a strategic bet that owning the full stack will significantly reduce friction for institutional clients, fostering stickier and higher-value relationships compared to selling point solutions. The regulatory dimension is also a critical differentiator, as operating simultaneously under MiCA for crypto-asset services, DORA for operational resilience, and MiFID II for investment products presents a significant compliance overhead that smaller entrants often struggle to manage. For clients such as banks, insurers, and large fintechs requiring a fully licensed and auditable partner, this multi-licence position offers a compelling competitive advantage.

Near-term milestones for the newly formed group include the pace at which the combined product catalogue is unified, the adoption rate of investment and savings modules by Treezor's existing institutional clients, and whether the group will pursue further European licenses or acquire additional capabilities to expand its geographical reach beyond its current four-country footprint.
