Thorsten Trapp, Co-Founder and CTO

Serial entrepreneur Thorsten Trapp co-founded tyntec in 2002. His deep knowledge on the technical side of telecommunications combined with his ability to spot emerging trends and develop products and services to meet industry demand mean he is a highly regarded industry expert who is a regular feature in the global trade press.

Based in the company’s technical headquarters in Dortmund – where he studied computer science and biology at the Technical University – Thorsten developed the company's Mobile Messaging platform architecture which powers tyntec’s core business and is chiefly responsible for the company’s technical innovations and intellectual property. In this capacity he authored all nine of tyntec’s patent families and has been named in 33 patent applications in total. Amongst others, he is the inventor of tyntec’s dynamic SS7 platform, its Mobile Number Portability System and disruptive tt.One product.

Thorsten is a hands-on CTO who is active in driving many parts of the business, including the development of new business models to support tyntec’s products and services. He is also experienced in negotiations with investors and global enterprise clients. In addition, he possesses first-hand management experience in successfully overseeing the growth and transformation of his company from a handful of employees to the global 150-person company it is today.

Having played a key role in bringing enterprise-level SMS services to multinationals on a global scale, Thorsten believes that the next challenge the telecommunications industry faces is to master the convergence of telecommunications and emerging IP-based communication systems.
