Our story
sustainadiligence was started by Christoph Ganahl who spent the past 20+ years working on M&A / fundraising transactions and who in recent years developed a focus on ESG considerations as part of M&A deals. Christoph is a father of two and wants to do his bit to leave his children and grandchildren a livable planet - in terms of the environment, but also regarding equality, justice and peace.
Christoph has almost 20 years experience working as advisor to SMEs on M&A transactions and IPOs, as part of the M&A team of a large corporate and as investor providing both growth equity and buy-out capital to SMEs in the German-speaking region. In addition, Christoph has served in non-executive board roles and is a member of the Supervisory Board of a 220 year old family firm, where sustainability considerations have been on top of the agenda for decades but are becoming ever more important in light of current regulatory developments.
Christoph holds a Bachelor's degree in Accounting and Finance from the London School of Economics (LSE), Master's degree in Economics, Finance and Mangement from Universitat Pompeu Fabra, Barcelona and an MBA from INSEAD (Fontainebleau / Singapore). He is a Certified Sustainbility Expert and a Certified Supervisory Expert.
At sustainadiligence, we draw on our large network in the sustainability and M&A sector to provide you with the best possible support for your specific project.
"Knowing from different perspectives - as investor, board member and advisor - how burdensome and complicated the ESG frameworks and related regulations may seem, I am convinced that implementing ESG considerations in your deal-making process can create significant value - both for your investment as well as the planet and society as a whole. Whether you are already experienced in this field or just beginning to think about the ESG-side of deals: sustainadiligence is here to guide you on your journey - and to help you create additional value in your deal."
sustainadiligence is a supporter of the Sustainable Development Goals (SDGs).
