Weinberg Capital Partners has invested in Summa, a newly formed French accounting and advisory platform created through the merger of six independent firms, in a move that aims to consolidate a fragmented professional services market.

The investment marks the fourth transaction from Weinberg’s WCP#4 LBO fund and supports the launch of Summa as a comprehensive accounting, audit, and consulting firm serving small businesses and mid-market companies.

Led by co-founder and President Christian Vaingnedroye, Summa brings together 150 professionals across the Paris region and is targeting €50m in revenue through an active external growth strategy. The group offers a full range of financial, tax, labour, and legal advisory services.

The French accounting sector, still dominated by small independent firms, is facing generational succession issues, talent shortages, and mounting pressure to digitise. Summa’s integrated model is designed to meet these challenges by pooling investments and expertise, while preserving entrepreneurial autonomy for each member firm.

Weinberg Capital Partners said the transaction reflects its commitment to backing B2B service platforms with strong consolidation potential and value creation through M&A.

Several additional firms are already in discussions to join Summa, accelerating the company’s geographic reach and service depth.
