Prospex has the most exhaustive, rich and accurate dataset on Swiss companies.
I spent 15 years building data systems in Python and ML. When I started working on B2B prospection in Switzerland, I found that global prospecting tools have incomplete, outdated Swiss data. The local alternatives are directory listings from the 2000s.
Switzerland is a small market, multilingual, split across 26 cantons with separate commercial registers. No global player will invest in getting this right. So I decided to build it myself.
Prospex pulls from 15+ Swiss sources (commercial registers, company websites, job postings, public procurement, trademarks) and links them into one company profile.

I've been working with a couple pilot teams to refine the product, and now it's time to open it up. If you sell B2B in Switzerland, try building a market and tell me what's missing. If you're curious about Swiss company data, the guides section has deep dives into the public registers.
Because other global B2B lead generation services have usually incomplete and inaccurate data for Switzerland. Switzerland-specific services are usually archaic and expensive.
