About Sven

Hello, I'm Sven 👋

I am an expert in the technical implementation of digital marketing and sales, especially in B2B.

1️⃣ CRM systems like HubSpot, Close, Pipedrive:
Clean pipelines and tracking of contacts, leads, and customers. So that every employee knows what needs to be done.
If necessary, with integration to other systems via n8n or Make.com.

2️⃣ LinkedIn (Ads & Classic)
Visibility in your own target market.
Sales-strong profiles and posts as classic marketing. To generate new potential customers who don't know you yet and are interested in your service or product. Result: More market penetration, visibility, and customers.

Are you specifically looking for support?
Write to me and let's talk briefly.

PS: I am happy to support, regardless of whether it is a new HubSpot or LinkedIn marketing setup or an optimization.

Experience

  • Maschinenfabrik Leonhardt GmbH
    PROJECT: LinkedIn (Classic & Ads)
    MECHANICAL ENGINEERING
    October 2025 - Today (10 months)
    Through LinkedIn Marketing:
    ✅ 130,000+ Impressions
    ✅ 50+ New Prospects
    ✅ 2+ New Customers

    👉 Initial Situation
    Before the collaboration, Leonhardt wanted to increase market penetration in German-speaking countries. The acquisition channels were occasional trade fairs, recommendations, and existing customers. The company lacked online visibility and had no digital sales.

    👉 Results
    As part of the collaboration, the LinkedIn profiles of the management and the company were revised to be clearly perceived as solution providers rather than just machine suppliers. By introducing LinkedIn advertising, the relevant target group could be specifically addressed.

    At the same time, the company developed into the digital leader in its niche, with permanent visibility among potential customers and clear market positioning.
