How we invest

We look where conviction matters more than consensus.

Npercent is a closed investment club under Swiss law. We pool our own capital to support exceptional founders at the beginning of their journey—thoughtfully, independently, and for the long term.

01

Early by design

We partner before the obvious signals appear, when clear thinking and useful feedback matter most.

02

Technology at the core

We look for technical differentiation, durable insight, and products that can reshape established markets.

03

Swiss roots, global ambition

Our home market is Switzerland. The companies we back should have the potential to matter far beyond it.

04

Capital plus context

Our members bring experience across technology, investing, operations, and company building—not a prescribed playbook.

Our origin

Why 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.

To any founders in Switzerland and Europe raising from angel to seed: do not hesitate to get in touch with Npercent.

The people behind the capital
