Nils H. Thommessen

I have the pleasure of leading Summa Equity AS’ day-to-day operations. To me, my job represents a perfect match with the 3 pillars of my professional life; doing good deals, leading really smart professionals and taking on the global challenges we face today.


I am a very affectionate supporter of Summa’s investment philosophy. Companies are the corner-stone of most societies, and their importance for people’s welfare can hardly be overrated. Here at Summa, we believe that companies with a positive impact will outperform other companies. And as we are here to create superior returns for our investors – that’s why we invest in them. I really believe that our companies’ purpose, combined with our capacity when it comes to competence, capital and network, will contribute to growth and prosperity for our portfolio companies, and thereby for society and our investors. This is why I am proud to be a part of the Summa team.


Before I became part of the Summa team, I spent many years as a transactional lawyer at the Norwegian law firm Wiersholm, where I have had leadership roles for more than 15 year. I also spent six years as Wiersholm’s Managing Partner during which time I lead the firm through significant changes in their operating model.
