Prospex helps Swiss B2B sales teams build a list of the companies worth their time, and keep it accurate as those companies change. Prospex then watches that list, and tells you the week a company on it is worth calling.

Hi Product Hunt! I'm Semion, the solo founder of Prospex. 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 When I started working on B2B prospection in Switzerland, I found that global prospecting tools have incomplete, outdated Swiss data.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. It watches for changes over time: a company just hired a new CTO or won a public contract. We have 241,000 enriched company profiles so far out of 734,000 active Swiss companies. We detected 129'000 sales opportunity signals, and that's just on the past four weeks. 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.

swiss business is still running on quiet trust and introductions. when the data is this clean in a tight market outbound feels like an "intrusion" not discovery. wonder if hyper accurate data actualy makes buyers trust you less...

@konstantin_tikhaev Thank you for your comment. I think that in a general sense you're probably right, but this really depends on sector and customer sizes. But yes, even the most accurate lead generation only gets you only half the way.
