Supporting technological innovation at its earliest stages
We are a closed investment club under Swiss law, with a key focus on early-stage VC, technology, and Switzerland.
Get in touchWhy We Do This
Switzerland’s venture capital scene is increasingly affirming itself as one of the world’s most dynamic, vibrant and strategic centers of technological innovation.
In order to support brilliant founders and start-ups at the earliest stages of their journeys, we have pulled our capital together and founded Npercent – a closed investment club under Swiss law.
With our resources, experience, and expertise, we aim to be true partners to our investee firms, people, and projects.
We aim to deploy our capital starting in early 2026 – to any founders raising for their angel and pre-seed rounds: do not hesitate to get in touch with Npercent.
