We have a very strong leadership team in place and I have full confidence in them and in the foundations we have built for our next phase of growth. This is the right moment for me and for Similarweb to begin the process of identifying the leader who will take the company forward. I am proud of what we have built and confident in everything still to come. I look forward to leading the business through this transition and to working closely with the Board to find the right successor.”
