I have been working with proper API for just under a year and would recommend the experience to anyone looking for advice on how to build wealth in Germany. Denis has provided me with customized advice on how to best prepare for my retirement with the tools and asset classes available in Germany. Walking me through options and adjusting the proposals until it fit my risk appetite and investment timeline.

We had a very thorough breakdown of very complex topics by a capable consultant. From the possible tax benefits to pension plans and relevant insurances, we were able to make very conscious decisions thanks to the competent, patient and very friendly consultant that worked with us.

I've only been with them for 4 months, but Christian and his team seem great. Christian spent a lot of time with me helping me understand all the options from their offerings, and figuring out which are most advisable for my situation. He also helped me at the start with an urgent deadline I had, which was very much appreciated! I can't speak to the long term performance yet but it seems like I am in good hands.

We have been working with Proper API since a little more than a year and we have no complaints. They are always ready to answer all our questions, they act quite fast in whatever changes we want to be done to our policies or investments. Im specially satisfied with the works of Dennis, for his honesty and proactivity to always get us the best deals.

Can’t recommend them enough! I have been working with them for an over a month now and the service has been top notch. I have felt heard and supported every step of the process.

Together with proper API we did a good investment and saving plan. I really like their way of approaching the things and advices given. They are reachable when needed and quickly helping and supporting the issues you faced.

It’s been a wonderful experience working with proper API. Christian has been incredibly insightful interesting and hands-on with the support he has provided. I’m very happy to be able to get all this insight from him and all the advice. I would highly recommend the service to all experts because it’s extremely accessible and very helpful.

Deep understanding, professionalism and kindness. I am very grateful to Denis

Ich habe vor Kurzem mit der Umsetzung meiner Projekte zum Vermögensaufbau begonnen und bin bisher sehr zufrieden mit der Beratung durch Denis und Pierre. Obwohl sich die Projekte noch in der Anfangsphase befinden und konkrete Ergebnisse noch ausstehen, fühle ich mich durch die kontinuierliche Betreuung der beiden sehr gut begleitet. Ihre professionelle und zugleich persönliche Art schafft Vertrauen und gibt mir Sicherheit bei jedem Schritt. Ich konnte bereits jetzt viel dazulernen und freue mich auf die weitere Zusammenarbeit. Ich bin zuversichtlich, dass die Projekte sich positiv entwickeln werden und bedanke mich herzlich für die engagierte Unterstützung!

I really appreciate the support and advising I've received from Denis. He's been a really great person to work with, and I trust his judgment. He's also over-the-top communicative and very organized. Ten stars, rather than five.

I had a great experience with the team. Whole team is quite proactive and actively works on the tasks. Thanks for great support.

Dennis is my point of contact and he has been a tremendous support to understand nitty gritty of financial investments in Germany and how we can leverage different schemes to reduce our taxable income and make our future secure. He has suggested us plans that meet our individual goals and personal situation. And I also have subscribed to their monthly service where I use them for all my questions starting from personal topics like eleterngeld/ kindergeld to processing my claims for my private insurance to any questions I have on financial topics. I highly recommend this service as they are very supportive and prompt, at the end of the day provides me with peace of mind

Being an expat in Germany I was looking for a professional financial advisor, I got in touch with Andre from Proper API who helped me understand the complex German tax/finance system and provided me with a customized service according to my need. I had several online meetings with Andre to strategize my financial goals and he introduced me to pension plans and investment opportunities. I highly recommend Proper API to anyone seeking guidance finance.

I've been working with Denis for the last couple of months, and he has been great at not only making a plan that works for my financial situation, but also keeping me informed on insurances, investment opportunities and more. I can't recommend Proper API enough!

As immigrants, coming to Germany has been a challenge in many aspects, and in this overwhelming situation, it is easy to leave unattended our financial strategy. Proper API was great for us. From the moment we started getting their advice, Christian Klingsporn (our advisor) made a diagnosis of our situation and started to clearly outline a plan for us. We’re confident that Proper API has given us the best advice and we will definitely come back to them in the future for investments, insurance and finance related support.

Very good service, detail oriented with high level of patience

I highly recommend Proper API for anyone seeking expert guidance on pensions and real estate investments. The team at Proper API took the time to understand my financial goals and crafted a tailored strategy that addressed both my retirement and investment needs. We were unhappy with our first financial consultant and then we came across Proper API. Since then we always had a good sense of security with financials especially being expats in Germany where all the documenatation is in German. Dariusch explained complex pension options with clarity, even explaining the contract so that we don't miss out on details. He advised us on financial planning strategies and even went outside what benefits them. Our first real estate investment journey with Pierre was also very positive. He guided us through the entire process as we took baby steps with the biggest purchase in our life. The most important highlight was that we were not pressured into making a decision. We didn't like the first property that we visted but we were not persuaded into getting into that deal. He showed us more offers until we got one we liked. He was always there with us during the entire process from apartment visit to loan application to the notary and even after that. He helped in streamlining all the communication with the seller that made us confident that there is someone on our side on this complex process.

I had a great experience with Proper API Services! Their personalized financial planning helped me navigate my needs with tailored advice that made a difference. Their affordable assistance made complex bureaucratic processes straightforward and manageable. The quick response time ensured I never felt left in the dark with my queries. I highly recommend Proper API Services for reliable, efficient, and cost-effective financial support.

Christian is very knowledgeable and patient. Explained everything in details and I feel we are at good hands to support us to take the best decision possible. Thanks a lot!

Lukas took his time to explain everything to me in detail. He was also transparent.
