“Impressive! This firm dug into our tech and got started fast! Their work was excellent and more importantly, diligent! They stood behind their work and took ownership! I give them 5 stars for sure!!! ”

"Erik Stenman was the first CTO of Klarna and, without a doubt, one of very few key people behind its great success. During Klarnas early years Eriks ability to transform C-level Management requirements in to comprehensive and strategic development tasks as well as being a part of the development team that performed those tasks was an invaluable asset for Klarna. As Klarna grew Erik, very smoothly, grew with the company and his responsibilities, handling people and larger strategic issues with the same professionalism and positive attitude as ever."

"I really enjoyed our lunches during the year, you helped me a lot whether you realized it or not :)"

“We were able to convince Erik to join our SaaS start-up as interim CTO in a critical MVP development phase. His track record speaks for itself, but what we found most appealing was his humble attitude and pragmatic approach in dealing with us (the company founders) as well as our board.

Erik and his team went to great lengths when it came to developing our target architecture after reviewing our initial plan thoroughly. While we as founders talked a lot about product vision and target picture, he grasped quickly that we were missing a proper technical roadmap and took initiative immediately.

Over time, Erik became more operational and worked closely with our Head of Engineering as well as engineers ensuring they would deliver consistent hiqh-quality output. At this stage, we started feeling confident that we can actually deliver our SaaS solution to the first set of clients. Erik further interviewed most of our hires himself, helping us to form a reliable and motivated engineering team.

Eventually, and also thanks to Erik's contribution, our company was acquired by a strategic buyer after only 18 months mainly due to our innovative technology.”

“Erik supported my company Sika Health in early days as a Technical Advisor. His background having lead and scaled technical teams at Klarna was a distinguishing factor since our business in the health payments space has many elements in common with the Klarna product. He helped me develop an initial technology roadmap so that I could understand who I needed to bring onto my Engineering team to deliver on this roadmap.

Additionally, he’s been a trusted advisor to me personally as a first-time founder/CEO building in fintech. I’ve been able to talk with him about a variety of topics as I’ve built the foundation for growth in my business. I would highly recommend Happi to any early stage founders and executives building in tech who need a thoughtful, warm, and experienced executive advisor to help them start or grow their business.”
