Very clear in communication! very knowledgeable and experienced in investment and finances. Highly recommend working with Proper API.

I have to admit, I was a bit skeptical at first. It’s always hard to know who to trust when looking for a service like this. But Proper API completely exceeded my expectations! Denis and Pierre were incredible from day one; friendly, professional, and genuinely helpful every step of the way.

They made a process that could have been stressful feel easy and smooth. Their expertise, patience, and attention to detail really stood out, and it’s clear they truly care about their clients. I want anyone looking for reviews before making a decision to know this: Proper API is the real deal. They deliver exactly what they promise, and working with Denis and Pierre made the whole experience a pleasure.

I can’t recommend them highly enough!

Out of all the investment advisory firms I spoke to, Proper API came across as the most professional and customer focused. Impeccable onboarding experience, structured thinking and streamlined admin processed are 3 key reasons I look forward to an enduring relation.

ProperAPI helped me understand the nuances of German tax and insurance system in the most simple way possible. It helped me take key decisions to build a strong roadmap towards achieving true financial independence. To someone who is new to Germany and has very less knowledge about financial investments in general, I can highly recomment ProperAPI.

I've been with them for now more than 6 months, Lukas and his team has helped me a lot in understanding the German tax system and financial infrastructure. It was a great experience for me from no information to now a better understanding of the system. Lukas spent a lot of time with me understanding my situation and helped me to understand all the options from their offerings, and figuring out which are most advisable for my situation. The response of the team until now is very prompt and much appreciated!

I feel lucky that I saw an ad with proper api services. My husband and I did our full financial strategy with Dariusch and his team - from health insurance and pension to investments. After a year working with the guys, I feel financially educated and safe. One thing I want to highlight in particular is the service level. No matter if we got cold feel about an investment or needed an extra call to ask questions - we always got extra attention, what is absolutely crucial when customers trust you with money.

Proper API has been a real help in navigating the German system, something that can feel overwhelming as an expat. Their team clearly knows their stuff and we appreciated how approachable and supportive they were throughout the process.

They took the time to explain things in detail and clearly, offered expert and honest advice, and were always willing to answer questions (no matter how small). It really felt like they had our best interests in mind, and that made a big difference.

If you’re new to Germany and trying to make sense of everything, I’d definitely recommend reaching out to Proper API. It’s good to have someone reliable in your corner.

Working with ProperAPI has been very reassuring and smooth. They are very patient in answering all my queries promptly and offering me tailored-advice according to my circumstances and needs!

I was introduced to ProperApi by my friend who is enthusiastic about different investments plans recently and had the pleasure of working with ProperApi that truly exceeded my expectations, especially as a non-EU citizen navigating the financial landscape in Germany.

From the very beginning, Denis was incredibly knowledgeable and attentive. He took the time to understand my financial goals through multiple discussions and tailored a strategy that aligned perfectly with my needs.

What impressed me the most was the seamless integration of Proper API into their services.

Thanks to the team's expertise and Denis's dedicated support. Denis is really patient with his clients and explains every complicated German documents in English which is really helpful for expats who don’t speak German.

I highly recommend this investment management company to anyone looking for a reliable partner in their financial journey, especially if you're navigating the complexities of being a non-EU citizen in Germany.

Proper API has offered me great service!
From regular consultation meetings to understand their business model and what would be the best financial approach for me, to finding me a property, joining me at the notary, taking care of all the contracts, setting up the lease agreements, etc etc...they were there each step of the way. Can really recommend using their team.

Amazing Customer Service. Really friendly guys who know what they are doing. I have gotten really good advice on managing my financials, and I'm really happy about it

I've received consultation services from this company regarding insurance and investment, and I couldn't be happier with the experience. The team is professional, efficient, and incredibly responsive. I especially want to highlight Lukas, who has been a pleasure to work with—knowledgeable, attentive, and always quick to provide clear and helpful advice. Highly recommended for anyone looking for trustworthy and competent financial guidance.

I am impressed by the Professional and friendly manner all my questions were handled and the attention to Details as well as the Knowledge of current Financial Instruments relevant to modern Economics and the dedication and flexibility to develop a personal strategy to financial Freedom. Looking forward to more Engagements and Interactions with much more optimism!

It was great working with Lukas. He was able to explain everything clearly to me with patience and supported me all the way through with great answers to all my questions

Christian and Team are really rockstars! From swift onboarding to tailored investment strategies. Everything was top notch.

Great customer service, Denis and the rest of the team have been very effective and professional. They have been very helpful every time.

Firstly, a huge thanks to Christian who has kept it professional yet engaging from the start.

Secondly, the amount of pre-work done including calculations and estimations of your personal financial plan before each call is very impressive. As someone who wanted high standards, they definitely delivered.

Thirdly, it almost felt unreal with the amount of knowledge that was shared with me through multiple hours of calls with no charge and even before signing any contract with them.

Fourth, their knowledge with respect to pension plans and private health insurance was quite formidable considering the cross questioning of alternatives and choice of strategy.

Lastly, the continued service is still to be tested but given the confidence instilled by Christian and his team, I'm sure it'll be fine.

Is great to have someone like Denis who can explain you how the pension system in Germany works, and more than that to have someone that offer you a life financial strategy.

They always clarify your questions, give you examples, give you the necessary information and advice you regardardin your personal situation. Is up to you, then to decide how do you want part of it.

I can only recommend the service. Thank you !

Thank you!

Great experience so far. I'm always very well informed about everything and have detailed answers to all my questions.
5 stars all around.
