STS Ventures is a tech-oriented VC that is strongly differentiated from other venture capital funds primarily by its focus on camel tech start-ups and its investment focus on niche markets. Camel start-ups are companies that are resilient and resistant and can therefore survive even under difficult economic conditions, pandemics or global crises.The VC bundles the business angel activities of the Cologne-based serial entrepreneur and investor Stephan Schubert. In addition, business angels, entrepreneurs and family offices who are friends or in close business association with Stephan Schubert invest jointly with him through STS Ventures. Since the advent of the internet in Europe in the late 1990s, Stephan Schubert has invested in numerous technology-driven start-ups and has become one of the most active and experienced business angels in Germany.

| MANSIO | MANSIO's unique IT solution enables cross-company relay transportation. Thereby, the semi-trailer is handed over from one truck to another at a parking lot along the route. After this “trailer swap”, the truckers drive back to their particular home regions with their own semi-truck and the swapped trailer from the opposite direction.In theMANSIO transportation system, empty runs to find return loads and parking-search-traffic are eliminated. Semi-trucks can be used very cost-efficiently in a second shift and - by that - generate additional revenue. In the future, the MANSIO trailer handover system will also allow battery-electric trucks with short ranges to be used on certain sections of long distance transport routes. |  | Seed | Jan 06, 2025 |  |
