What I Do at Ynfinite

As the technical lead at Ynfinite, I handle everything that goes on behind the scenes: I develop, test, and improve—preferably until an idea becomes a system that really delivers.

From our CMS architecture down to the tiniest performance details—I make sure our clients get websites that aren’t just beautiful, but also high-performing.

My superpower

I think in code, but always with the user in mind.
Whether it’s web performance, SEO, or accessibility: I love turning complex requirements into sleek, elegant solutions—and I’m only satisfied when everything is still update-proof tomorrow.

And yes, I’m the one who’s still hunting a bug at 2 a.m. because I saw it in my sleep.

Why I founded Ynfinite

I wanted to build a solution that finally takes the pressure off companies—technically, in terms of content, and in marketing. No cookie-cutter approach, no agency frustration, but a system that thinks for itself.

Together with my team, I continue to develop Ynfinite every day. Because good software isn’t a coincidence.

Fun fact about me

I have more GitHub repositories than vacation photos.
When I’m not coding, I make pizza (not from a kit) or paint Warhammer miniatures with an absurd level of detail. Precision isn’t just my thing in code.

What the team says about Markus

“If something isn’t working technically, Markus will make it work anyway.”

Practical tips and sound strategies to put your website on the road to success.

Why automated social media is a game changer for SMEs and B2B

Imagine having an extra employee who works around the clock to ensure your business remains visible online.
They post on LinkedIn, Instagram, and Facebook, maintain your Google presence—all without you having to invest a single minute of your time. Sound like science fiction? This is exactly where automated social media comes into play.

Creating SEO texts with AI: How to rank your content on Google

A blog post in five minutes? Sounds good. But what good is it if no one can find it? The truth is: AI can be a huge help when writing— but only if you know how to link it to SEO. Because a beautiful text is not necessarily a successful text. It's about relevance, structure, and how search engines understand your content in the first place.

Investing in scalable SaaS startups: What our investor sees in us

What makes a business model truly attractive to investors?
It's not just revenue. It's not the glossy PowerPoint presentation. It's scalability.

Digital business models that don't cost more as they grow. Systems that don't collapse when there are suddenly 100 customers instead of 10. And infrastructures that can grow without becoming chaotic.

That's exactly what our investor sees in Ynfinite. And that's exactly what this is all about.

Why your website needs more than just a translation button

Let's be honest: a flag icon and Google Translate in the background do not constitute an international strategy. If you really want to launch your website in multiple languages, you need genuine language versions—technically sound, search engine friendly, and completely under your control. And that's exactly what Ynfinite's Translation Engine is for.

Thank you, Lennart, thank you, Reinhold, thank you, Tina!

A great product supported by a great team. We can wholeheartedly recommend Yfinite's services and look forward to working with them again.

Our website was created by Ynfinite and it turned out really great. From our first contact with Lennart to the operational creation with Reinhold—everything went perfectly!

We had expected it to be much more complex and time-consuming for us, so we are all the more thrilled with the end result.

I can wholeheartedly recommend Ynfinite! Highly recommended!

We switched to Ynfinite some time ago, and it was definitely the right decision. Previously, our internal processes and interfaces were spread across a wide variety of systems, which not only made it difficult to maintain an overview, but also made our daily work unnecessarily complicated. Our old website, which was hosted on an external server, was particularly problematic. Access was restricted, and individual customizations were hardly possible.

With Ynfinite, we finally have the flexibility we have long desired. We can manage, customize, and develop content ourselves, without any technical hurdles. The system is intuitive, powerful, and, above all, future-proof.

A big thank you goes to the entire Ynfinite team for their excellent cooperation. We would particularly like to mention Reinhold, who supported us as our contact person with incredible commitment. He was always available, patient, absolutely reliable, and genuinely interested in our concerns.

We are very pleased with this successful partnership and can recommend Ynfinite with a clear conscience!

Markus Hilgers
A huge company with top employees. And the websites in the headless CMS are the jack of all trades. That means you'll never have to create a new website again if something changes or needs to be expanded. Just come up with a new design or adjust the building blocks. So it's absolutely cost-effective and time-saving. Just MEGA. I can only recommend everyone to try it out. But be careful, success is guaranteed.
For me, there's nothing else since then.

Everything was quick and good👍👍👍👍

5 stars for Ynfinite!

We are absolutely thrilled with the professional and first-class advice and the customized creation of our website by Ynfinite. As real estate agents, it was particularly important to us to have a website that is not only visually appealing, but also perfectly tailored to our needs and those of our customers. Ynfinite delivered all this and much more!

From the very first conversation, we felt that we were receiving excellent advice. The team took the time to understand my requirements in detail and developed a solution that is both functional and user-friendly. The implementation was quick and smooth, and the result speaks for itself: a modern, professional, first-class website that presents our services in the best possible light.

We can warmly recommend Ynfinite to any real estate agent looking for a customized, professional website. Five stars are absolutely deserved here!

Ludger Ernesti
This company is almost unique in its implementation of online real estate projects and brokerage services, and is particularly competent thanks to Lennart Ewers.

Olaf Ehlig
A great experience from start to finish. Lennart from the sales department particularly impressed us with his expert advice and commitment—always friendly, professional, and solution-oriented. Kudos also to Reinhold in customer support, who took care of all our concerns quickly and reliably. That's the kind of customer service you want!

Highly recommended—we'll be back! 🚀💯

Ypsolution GmbH created my website and continues to maintain it—and I am absolutely satisfied! A highly competent team, excellent advice, and great value for money.

All my requests were handled professionally, and even after completion, the support is first-class.

Highly recommended!

Ralf Schnatz Real Estate
Working with your teams was really great. Communication across all departments was transparent, always solution-oriented, and you have a very good understanding of the individual needs of customers and know how to implement them.

I also really appreciated how quickly you got to work to get my site online in a record time of six weeks. The support after the site went live has also been excellent, and not having to deal with constantly changing contact persons is definitely a plus.

Yes, I would recommend you anytime because you are an amazing team and obviously work in a particularly customer-centric way, which is very pleasant.

IMMOADDICT Real Estate Services, LLC
Ypsolution is a truly innovative company.

My new homepage needed to be designed as a premium brand, incorporating all the latest social media tools.

The highly complex module system made it quite affordable compared to other top providers.

My questions are always answered by friendly people who are very competent and proactive. You also benefit from the continuous development of the product.

Conclusion: Here, you are not left alone after purchasing the package. So far, everything is going great with ypsolution...! Small errors are fixed immediately.

Christian Ley
We at maison Immobilien are very satisfied with our collaboration with YPSOLUTION. The team is very pleasant to work with and always professional.

With the support of YPSOLUTION, we have built a new website that is very user-friendly and tailored to our company's needs thanks to flexible content and individual customizations. The easy-to-understand video tutorials for the Ynfinite software, which is used to edit the website, enabled us to quickly familiarize ourselves with the system.

The support provided by YPSOLUTION is particularly noteworthy. When questions arise, we receive quick feedback and our concerns are addressed within a day.

overall, we can recommend YPSOLUTION without reservation. The combination of pleasant cooperation, well-structured software, a customized website, and outstanding support makes YPSOLUTION a reliable partner for our requirements.

maison Real Estate
I am infinitely grateful to Ms. Gayer for creating and maintaining the content so well and for teaching me the basics of how the system works.

The launch of the website by Ms. Wetter and Mr. Müller also went very well, faster and better than I had expected. My website has become much more professional and attractive and is well received by my customers and potential customers—even compared to the competition.

What I particularly liked, and which was also a key reason for choosing this website, was that I can modify the website myself within a specified framework without having to call in a programmer or system house. This gives me a great deal of flexibility with this website.

Bertram Real Estate
We can wholeheartedly recommend Ypsolution and would like to express our sincere thanks to the entire team! Overall, the interaction was extremely pleasant and open, which we greatly enjoyed.

Their extensive experience in the real estate sector was always evident and made the relaunch of our website much easier. Our Sparkasse design differs from others in every respect, but retains its high recognition value.

We particularly like the fact that we can now design content for the website ourselves—quickly and effectively.

S Finance Euskirchen
What I immediately liked about YPSOLUTION was that the websites are clearly structured—but what impressed me most was the technology behind them. As a sales trainer, I regularly deal with agencies and websites, and I was so impressed that I bought the large version straight away.

Then I first got in touch with the copywriter, and she immediately impressed me: she's the first person in 20 years of self-employment who immediately understood the company and was able to convey a few things much better than we could ourselves. A solid A+++.

The second time I was impressed was when the site was finished earlier than expected, rather than 2 to 3 months later. Collaboration: excellent, coordination: excellent, I can only recommend them to everyone, and I would gladly work with them again.

We will continue to work together because I really appreciate the work and I would like to take this opportunity to once again express my sincere thanks for the particularly great work.

Remscheidt Sales Training
Hello Ms. Aust, hello Ms. Jakob,

we would like to thank you and your team once again for our website. Our customers, prospective customers, and the entire Hassel team are more than enthusiastic, and we can see that our online presence has become much more professional and unique as a result.

After a year of being online and developing our site, we can only say that it was the right decision to revamp our website and have you as a partner in this project.

From start to finish, you and your team provided us with expert support—a big compliment and an even bigger thank you for that! We hope to be able to return the favor in the near future.

Warm regards, Wolfgang Hassel & Chutharat Clemens and the entire team at Hassel Immobilien GmbH.
