Manser Ventures

Manser Ventures is a founder-led venture studio based in Zurich, Switzerland, founded in 2025. It creates and operates technology ventures, bringing product design, software engineering and go-to-market execution together under one roof. The studio focuses on solving real problems, building products in-house and scaling ventures when they demonstrate promise. It is self-funded and describes itself as a studio rather than an agency, with a small number of partner engagements also available.

Its portfolio includes Promptise, an open-source, Python-native framework for building agentic AI systems; Swiss Golf Simulators, a directory and interactive map of indoor golf venues across Switzerland; and ventures.swiss, a platform connecting participants in Switzerland’s innovation ecosystem. The portfolio also includes ventures in development, some operating confidentially.

Manser Ventures offers product development for web, mobile and AI-enabled applications, solution architecture, cloud and infrastructure strategy, security reviews and technical due diligence. Its venture-building services include market research, MVP development, positioning, go-to-market planning, operating-model design and support with capital and partnerships.
