I help tech companies attract and retain customers

My expertise

What I do

• Go-to-Market

  I help companies build scalable go-to-market engines by aligning marketing, sales, and customer experience around a unified bow tie funnel that connects acquisition, retention, and expansion. Whether product-led or sales-led, I design growth systems that drive results across the full lifecycle using the right channels, CRM architecture, and automation.

• Product-led Growth

  Unlock product-led growth by turning products into the core driver of your acquisition, activation, and expansion. I design systems that connect user behavior with go-to-market strategy — leveraging in-product triggers, lifecycle automation, and data-driven onboarding to scale growth efficiently.

• Inbound Marketing

  Attract the right clients with inbound marketing by creating valuable content and experiences they're already searching for – so they come to you, not the other way around. Instead of interrupting with ads, I build trust by solving your audience's problems and guiding them through their journey until they're ready to buy.

• SEO

  I help companies get discovered by the people already searching for what you do, using SEO to put your website and content at the top of Google when it matters most. Attract high-quality, intent-driven traffic that converts because it's built on trust, relevance, and real value.

• CRM and AI Automation

  Build lasting customer relationships and grow your business by combining smart CRM systems and AI automation. Good automations make sure nothing falls through the cracks – and help the go-to-market teams to have their hands free for meaningful customer interactions.

• CRO

  Get more out of the traffic you already have by using conversion rate optimization to turn visitors into customers. From refining headlines to streamlining checkouts, I optimize every element of your funnel based on data so more people take action, and your revenue grows without needing more ad spend.

• Jonas is one of the most knowledgeable growth experts I know – and fun to work with. He brought exactly the clarity and support we were looking for. I'd work with Jonas any day!

  Jean Founder

• It is difficult to come across real talent that stands out like Jonas. We were working together for over three years at the Cologne Tech Startup Fitogram. Working at an early stage Startup comes with many unforeseen challenges and it is crucial to work with a team that steps up their game and takes leadership when needed. That is exactly what Jonas did and does. He easily understood our business challenges and provided rich solutions. What makes Jonas really valuable is that he never stands still and that he is always eager to further educate himself. He was also the first one who introduced me to the OKR framework, which was later implemented at Fitogram, which had a significant impact on my work.

  I truly enjoyed working with Jonas and would like to do so again on any given day.

• Jonas helped me turn a passion project into a profitable company. He scaled our traffic with product-led and SEO-driven content marketing, automated CRM workflows, and an ROI-positive SEA system. Jonas doesn't just drive numbers – he builds holistic growth systems that work.

  Chris Founder

• What stands out about Jonas is how he combines analytical thinking and creativity. Jonas is a great leader and mentor. I would love to work with him again in the future. Any team can be happy to have him on board.

  Carolin Product Design Lead

• Working with Jonas is an absolute privilege. It's just easy to be around him – no matter if we talk content strategy, B2B SaaS marketing measures, or just about weekend plans.

  As a leader, he embodies trust, honesty, and approachability, creating an environment where everyone feels valued and empowered. His feedback isn't just insightful – it's a game-changer that helped me grow tremendously, both professionally and personally, in the last year alone.

  His knowledge of the SaaS market, B2B Marketing, great storytelling, cool content, the recruiting world, and outstanding designs is unmatched. He could actually brag about everything he knows, but stays very humble trying to share his know-how in a super friendly way.

  If you're looking for a leader who truly invests in his team, you won't find anyone better.

  What stands out most is his ability to listen, provide clear direction, and create an environment for everyone to learn and grow. No matter how busy things get, Jonas never hesitates to jump in and support the team.
