Recommendation
I had a free consultation with Hakan from Ersu Consulting and was really pleasantly surprised. He took 1.5 hours to give me honest, competent and structured advice and gave me tips that I could implement immediately. Many others charge several hundred euros per hour for this kind of advice, so I was really impressed by his generosity. Hakan is very genuine, helpful and human, and you immediately realize that he wants to offer real added value. I also had a second free call on the topic of performance marketing, in which Max gave me absolutely expert advice. Here, too, I was given a lot of practical input that I can implement directly. All in all, an extremely pleasant, professional contact and a clear recommendation.

I'm really very satisfied so far, especially the quick availability and the way he always elaborates on the topics.
Hakan gave me a good wake-up call just before settings etc. and also gave me tips, plus the ass-kickings, so so far really an 11/10.

What I particularly appreciate about Hakan is his calm and professional manner. He advised me competently on all my concerns, dealt with my situation individually and gave me access not only to his knowledge but also to his network, which made the consultation even more valuable. My recommendation clearly goes in his direction!

I had the opportunity to work with Ersu Consulting and was pleasantly surprised throughout.
From the very first conversation, you realize that there are real experts at work here, who don't just sell standard solutions, but respond individually to the situation and goals.
The advice was structured, honest and practical - no theoretical blah-blah, but clear strategies that you can use straight away.
I was particularly impressed by how quickly the weak points in my business model were identified and concrete solutions presented.
I can recommend Ersu Consulting to anyone who wants to develop their company professionally, optimize processes or implement new growth strategies.
Here you get real added value instead of empty promises.

I can only recommend Hakan to every agency owner. I actually never wanted to buy coaching again, I just wanted to get some non-binding information - but he completely convinced me otherwise. It was clear from the very first conversation that Hakan really has my best interests at heart. Now I'm excited to see where the journey takes me - because you really don't get in-depth, practical knowledge like this everywhere.

I had a very valuable conversation with Hakan. Although I said right at the beginning that it was still too early for me to make use of his services (as I was just starting my project), he took a lot of time and gave me important input for my further course of action.
His experience, openness and helpfulness left a great impression - absolutely recommendable!

It was a really great consultation!
I was able to take away a lot of added value and ask all my questions, which Hakan answered without hesitation. I was particularly pleased that I wasn't even pitched an offer, it was really all about real added value.

UPDATED: Thank you, Hakan, for the open & transparent consultation.
You took the time to give me honest and valuable input for my agency without giving me anything in return.
No superficial babble, but really good tips that will definitely help me and my agency.

A few of your tips have opened my eyes directly - both strategically and in everyday operations. I have gained new perspectives and now know more clearly what I need to focus on to get to the next level.

Thank you for your openness, your expertise and your support - something that is no longer taken for granted today.

I would absolutely recommend you to anyone who has the chance to talk to you. 🙏

UPDATE 12.09.2025: After our conversation, I was able to close 18k with an existing customer using Hakan's strategy.

I have been consulting with Hakan for over 8 months and can really recommend him to anyone. He is a man of his word, very reliable and always ready to support you with his expertise. The collaboration was always professional and trusting, but at the same time pleasant on a personal level. Thanks to his support, I was able to learn a lot and make real progress. I am very grateful for the time and would work with him and Max (performance marketing expert) again at any time.

Anyone who talks to Hakan immediately understands that he knows a thing or two about online marketing, business models and entrepreneurship. We only had one in-depth conversation, but I realized relatively early on that the bro had already played the game several times.
It was a good conversation.
Good luck Hakan.

Greetings
Fatih

Hakan gave us incredibly helpful tips for our startup that we wouldn't have gotten anywhere else - he not only gave us detailed and personalized feedback on our store and explained exact points where we could improve, but also showed us examples of his own stores and talked about his experience. A super helpful conversation, we will definitely apply his tips!
Hakan was super friendly, professional and you could just tell that he is totally motivated to help other entrepreneurs.
Thank you very much!!! We can only recommend his advice!
