Transforming B2B Sales with Real-Time Data: A Q&A with Janik Deimann, CEO of Leadscraper

I am Janik Deimann, founder of Deimann Com GmbH in Hamburg. I have been self-employed in online marketing for around ten years and spent a good part of that time working with large German companies on their acquisition and growth. That work is where the idea for my current company came from, because I kept running into the same bottleneck from the other side of the table.

In January 2026 I founded LeadScraper, a B2B lead generation tool that works differently from the databases most sales teams are used to. Instead of pulling records from a static list, hundreds of AI agents search the live web and build a contact list that matches what you actually sell. Users describe their ideal customer in their own words across five free text fields, and the system interprets that description rather than forcing it into dropdown filters. Every result comes with company name, website, email, phone number and the right person to talk to, plus a visible source so you can check where the data came from.

LeadScraper is the first major project inside a broader plan for Deimann Com GmbH: an AI-first company builder that develops and runs operational software products.

We are bootstrapped, so buying growth was never an option. That turned out to be an advantage. It forced us to find product-market fit through conversations instead of through spend.

In the early months I worked obsessively closely with our first customers. I asked what they searched for, what came back useless, and why. Then we shipped changes within days. We still get slightly bewildered feedback about how fast a suggestion turns into a feature, and that speed is deliberate. It is also built into the product itself: after each search, users rate individual leads with a thumbs up or thumbs down, the system recognises patterns in those ratings, and the search logic adapts. Every customer effectively trains their own version of the algorithm, so two companies running an identical search get increasingly different results over time.

Growth followed from that rather than from advertising. Customers here in Germany got results, told other people, and came back. What surprised me was the next step. Enquiries started arriving from outside Germany, first from neighbouring markets and then further afield, from teams who had found us and wanted to know whether the system understood their market the way it understood ours. Answering that question honestly is what pushed us to make LeadScraper work internationally, and it now does.
