The bridge between ambition and tangible market success
At TUN. Sales, we believe that growth only has real value when it is sustainable. Many revolutionary high-tech and SaaS solutions fail to reach their potential due to the complexity of international market access, which is why TUN acts as the strategic and operational engine behind your expansion into Germany (DACH) and the Netherlands (Benelux). Founders with a predominantly technical background often focus on the technology for too long, causing commercial validation and finding the right product-market fit to fall behind. We are not external consultants, but an on-site sales partner and dedicated entrepreneurs who speak the language of technology and understand local business culture — connecting innovations to our network of industry frontrunners. Alongside the technically oriented founder (or manager), we are proud to serve as the commercial conscience.Contact us

Together with Sander, we approached various international investors and other interested parties regarding PowerUP at the GITEX trade fair in Berlin. I really enjoy working with Sander; he’s to the point, straightforward (with a sense of humour) and always open to sound arguments. Together, we’re building new business for PowerUP.
As Team Captain, Sander was responsible for Nedap Energy Systems’ German team and played a key role in further professionalising the internal organisation. He also played a major role in the overall development and professionalisation of the Business Unit and in achieving success in the key target market of Germany.
I thoroughly enjoyed collaborating with Sander. He brings a wealth of senior sales and market expertise. He possesses extensive knowledge of cleantech, alternative energy solutions, and H2 fuel cells. Furthermore, he is a pleasure to work with! During our joint assignment, he provided PowerUP with suitable business partners in Germany and the Netherlands and was particularly valuable within the CCTV sector.
