Who's Behind QUALITYCLICK?
Software since 1991. Affiliate marketing since 1997. Tracking that has worked for 26 years—without cookies, without networks, without compromises.
Jan Bischoff
Founder & Managing Director, NetSlave GmbH
I've been programming since 1991. I got into affiliate marketing in 1997—initially as an affiliate myself. I tried the networks and eventually decided to do things differently.
The first software was called QuickSubmit—for search engine submissions. Then in 2000 came the first German-language software for partner programs: "Partnerprogramm-Software 1.0". In 2004 I rewrote everything from scratch and renamed the product QUALITYCLICK.
I founded NetSlave GmbH on May 1, 2000 in Ilmenau. In 2002 we moved to Berlin, and in 2003 we got our first own office. We've been on Simon-Dach-Straße in Berlin-Friedrichshain since 2009.
"I build software that I would have needed myself as an affiliate and affiliate manager."

QUALITYCLICK—built for advertisers who run their own partner program
QUALITYCLICK is cookie-free affiliate tracking for advertisers who take transparency, control and GDPR compliance seriously. No affiliate network as a middleman. No third-party dependencies in the tracking core. Everything runs on our own infrastructure in Berlin.
The product has been in active use since 2000. Over 800 advertisers have used QUALITYCLICK—many of them for years. No venture capital, no SaaS conglomerate behind it—the product sustains itself.
More about QUALITYCLICK →cKonto—IBAN validation for developers and financial processes
In addition to QUALITYCLICK, we operate a second standalone SaaS product under ckonto.de: cKonto.
cKonto validates IBAN and bank account numbers in real time—via XML API or as batch queries. A REST API is coming soon. Used by developers, accounting software providers, and companies that need to keep payment data clean before it reaches the bank.
- Real-time IBAN validation (syntactic + BIC mapping)
- XML API (REST API coming soon)
- Monthly and annual subscription plans
- EU servers, German company, no US cloud dependency
cKonto didn't grow out of QUALITYCLICK—it's a standalone product that carries the same core philosophy: simple, reliable, GDPR-compliant, own infrastructure.
More about cKonto →How We Work
Our servers are located in Berlin—on our own hardware, in ISO 27001-certified data centers, powered by 100% green energy. No AWS, no Azure, no Google Cloud. That's a deliberate choice—for data sovereignty, stable latency in the DACH region, and independence from US cloud providers.
Development, support, and operations are in the same team. When there's a problem, the person solving it isn't in another country and isn't behind a ticket system with a 48-hour response time.
The Team
Our core team is small and well-coordinated. We work with a fixed group of full-time employees, an external server administrator with a backup company for emergencies, and freelancers we've been collaborating with for years.
Staying small isn't a weakness—it means every person counts and no decision gets lost in an approval marathon.
