Background
Joanna Poniwerski is a co-founder and Founding Partner of S&P Advisory Services, a Paris-based boutique M&A and corporate-finance advisory firm she helped establish (the firm has operated under this name since the mid-2010s, with a registered office at 13–15 rue Taitbout in Paris's 9th arrondissement). According to the firm's own partner page, she has over ten years of M&A experience in the European engineering-services sector and specializes in cross-border transactions.
Before founding S&P, Poniwerski worked in the M&A departments of European leaders in technology consulting and engineering, giving her direct sector operating context for the deals she now advises on. She is a genuinely cross-border operator, speaking four European languages fluently — German, English, French and Polish — which underpins the firm's positioning on Franco-German and pan-European deals.
She holds an MA in European Business from Royal Holloway, University of London. At S&P she partners with co-founder Ludovic Pejoux (also a Founding Partner, with a background as a Business Unit Director and Transition Manager and an MSc from ESC Montpellier). The two-partner firm offers acquisitions, divestitures, strategy consulting and executive-search services, concentrating on technology-focused consulting and engineering businesses.
Investment Thesis & Focus
- Operates as a sell-side / buy-side M&A advisor, not a check-writing angel or seed investor — engagements are advisory mandates, so there is no disclosed check size or equity stage.
- Deep specialization in technology consulting and engineering-services companies in Europe (aerospace & defense, automotive/transportation, financial services, technology).
- Emphasis on cross-border transactions, particularly France ⇄ Germany, leveraging multilingual (German/English/French/Polish) deal execution.
- Firm's stated purpose is assisting clients with "different forms of link-ups between companies" — i.e., mergers, acquisitions, divestitures and joint ventures — and "improving their growth potentials."
- Full-service boutique model spanning M&A execution, strategy consulting and executive search around the same sector niche.
Notable Investments
- Scalian → Tagueri AG (June 2020): S&P advised on Scalian's acquisition of 100% of Tagueri AG, a German technology/process-management consultancy (~300 consultants in automotive and aeronautics). This is the firm's most clearly documented transaction, memorialized in an S&P press release.
- Client/deal references displayed on S&P's "Deals & Missions" page include logos for Scalian/Avalin, Tagueri, Mayato, Brunel, Volkswagen (VW), and several other engineering/consulting brands — indicating advisory or search mandates with these organizations (specific roles per client not individually detailed on the public page).
