"The collaboration with Blockchain Source was an excellent experience for us. A very intelligent and innovative team and creating a long-term relationship with such a unique team that provides expertise across technical, business and regulatory challenges for a disruptive business like ours has been very valuable."

"I know Tommy professionally for more than 12 years and I got him involved when PXL Vision needed an external expert to review and advise on our digital id platform we were planning and designing. He has a rare mix of business acumen, strategic thinking and deep technical knowhow and could therefore give very valuable feedback, ideas and how to best approach from a business strategic point of view to best leverage new technologies like blockchain. I fully recommend him and his company's services."

"Tommy is a great entrepreneur, IT-specialist and project manager. He works very precisely, goal-oriented and structured. I did two projects together with Tommy and Blockchain Source as a client in a SME and an MNE environment. Tommy always managed to find the right approach to highly satisfy the needs for both type of clients. I highly recommend him and Blockchain Source for any kind of IT-projects where you need a trusted partner in exploring the potential of technology."
