We conduct ESG Due Diligence to save your reputation.

WHAT WE DO AND WHY IT MATTERS
«Lose money for the firm, and I will be understanding. Lose a shred of reputation for the firm, and I will be ruthless» — Warren E. Buffett.
We assess the ESG exposures that affect valuation, resilience, and long-term risk. This matters because ESG risks turn into liabilities mostly in the long run. A single finding that reveals regulatory non-compliance, a misaligned incentive system, or a future cash-flow risk can outweigh the entire advisory fee. 
Our analyses covers environmental liabilities and transition risks, operational realities behind social and labour practices, and the governance structures that determine compliance, incentives, reporting quality, and culture. We review regulatory and disclosure readiness (EU-Taxonomy, CSRD/ESRS, SFDR), evaluate supply-chain risks and human-rights obligations, and examine how ESG factors link to cash flows, CAPEX, OPEX, and valuation. Through management inquiries, communications and peer analyses, we identify gaps between stated commitments and actual practices.
ESG misstatements and hidden exposures can reshape a deal’s economics long after closing. Undisclosed environmental liabilities, weak compliance systems, flawed reporting processes, or exaggerated sustainability claims can lead to legal, operational, and reputational shocks that erode value.
In a landscape defined by rising regulation, activist scrutiny, and stakeholder sensitivity, disciplined ESG due diligence protects against greenwashing, litigation, and governance failures, and demonstrates the rigour your financiers expect.
WHO IS DOING IT and How
I blend a decade of Financial Audit, Capital Markets, and Mergers & Acquisitions at KPMG in Hamburg and PwC in Zurich with my academic insights into ESG and stakeholder governance.
My practical experience from 47 due diligence engagements equipped me with broad methodological knowledge around conducting due diligence.  
My ESG perspective builds on academic work at Bocconi University, where I analysed stakeholder interests in DAX strategies, management systems, and remuneration structures. 
As a doctoral researcher at the University of St. Gallen, I study the evolution of ESG discourse in academia and corporate communications and closely follow regulatory developments. I also maintain a dataset of more than 5,000 annual reports for best-practice and peer benchmarking analyses.
This blend of transaction experience and research-driven insight allows me to assess ESG exposures as strategic, financial, and cultural risks rather than isolated compliance topics. 
I work pragmatically and leverage modern data-analytics and AI tools, enabling fast, precise, and unbureaucratic diligence compared with larger advisory firms.
I have delivered guest lectures on M&A and due diligence at the University of Basel, the University of St. Gallen, and for SECA. I hold a Master’s degree in Accounting, Financial Management and Control from Bocconi University and continue my doctoral research at the University of St. Gallen.
