When I first started working with Proper API, I had a very positive experience. The initial phase felt supportive and consultative, and the guidance was genuinely helpful.
After about a year, my view is a bit more balanced. The service has become more transactional, with most interactions focused on relaying information or follow-ups rather than providing independent advice or proactive consulting.
Overall, the service is fine and I continue working with them, but I’d recommend starting with clear expectations around the level of long-term advisory support provided.

Company was suggested by some colleagues in the context of investments and real estate and I can happily say that was a really good suggestion.
Me and my wife we have been guided with patience, professionalism and really wide knowledge; we build together a plan to make our future safer not only looking on Investments but also on secondary steps that may help us to move ourself safer ( like additional insurances, additional agreements that we were definitively not aware of ); we were listened since day one and everything was build based on our necessities; all Proper APIs people that we are in touch with were ( and are ) super supportive and very friendly.
Purchasing an house and make proper investments have never been so easy!
I recently worked with Proper-API for investment consultations, insurance advice, and full support during my property-buying process, and I couldn't be happier with the experience.
Right from the start, the team was incredibly knowledgeable, professional, and dedicated to helping me make the best decisions. They walked me through different insurance options, ensuring I had all the protection I needed, and helped me assess whether the property I was interested in was truly worth the investment.
One of the best things about Proper-API is that their initial consultations are completely free. It really makes sense to take advantage of this, as it gives you a great chance to see what they offer without any pressure.
While there were a few delays in communication due to their high workload, it wasn’t anything that caused any real issues. Their commitment to providing excellent service and making sure I was happy more than made up for it.
Thanks to their support, I was able to secure a 6% discount on the property I purchased, which was a huge win for me. I’m confident I made a great investment, and that’s all thanks to Proper-API.
I’m 100% satisfied with my experience and will definitely be using their services again for my next property purchase. See you in a year guys!
The financial consultation was excellent with Lukas. He helped me identify gaps in my knowledge and gave a clear advice on how to improve. I think his guidance will definitely take me in safer side of my future. Highly recommend.
I had an excellent consultation service with the team. Andre took his time to create a personal investment plan for me, setup the accounts, and to my surprise, scheduled a follow up session to evaluate the performance of my portfolio thus far. The follow-up for me was customer-centric
I had an exceptional experience working with Proper API, thanks to my financial advisor, André. His knowledge, patience, and professionalism stood out throughout the process. André took the time to understand my financial goals and provided tailored advice that was both practical and effective.
He was always approachable, clear in his explanations, and proactive in addressing my queries. I felt confident and well-supported at every step. Proper API and André have truly exceeded my expectations, and I wouldn’t hesitate to recommend them to anyone looking for reliable financial guidance.
Thank you for your outstanding service.
I have been with Proper API for more than a year now, and they have been a great team. My advisor, Denis, has been a patient and friendly person to work with. He makes time to go through every details, multiple times if required, to help me understand the details of the process and next steps, as well as while introducing an investment opportunity.
I am happy with their service, and look forward to expanding my portfolio with the team.
When working with Proper API, both sides share a common goal: come up with the best insurance/finance tools to support their clients´ wealth generation and protection. They use concrete facts, numbers, and analysis to support their proposals and guide your decision making. They also don´t rush you into making any decision and whatever other scenarios come along, they are happy to incorporate them. The monthly service has also been great, saving me time and giving me peace of mind to ask them whatever I need to know, when I need to know. Opportunity for improvement: sometimes it´s necessary to follow up on them or send reminders to check if there are any updates with an ongoing request (e.g. to an insurance company), however, nothing critical that can´t be improved.
I recently had the pleasure of working with Proper API to purchase my first investment property for rental purposes, and I couldn't be happier with the experience.
From the initial consultation with Lukas to signing the contract and then collaborating with Pierre, the entire team provided exceptional support every step of the way. They helped me evaluate all my options over a 10-year horizon, considering tax benefits, cash flow, and overall profit. Their expertise made it easy to navigate the complexities of the German bureaucracy, including notary appointments, tax evaluations with an auditor, and property rental management.
What I appreciated most was their hands-on approach—perfect for busy individuals, so I did not have to get hands-on. Beyond visiting the property and attending the official notary appointment, I didn’t need to handle much else. They handled everything with professionalism and care, including negotiating with the seller (which worked out in my favor!) and ensuring the seller upheld their obligations post-sale. They also made sure that the property was rented out the same month as well.
Their property portfolio is constantly updated, offering a variety of options to fit your needs. There was no hard selling, and their patience throughout the process was commendable. They even helped me secure bank financing for the property.
I asked every dumb question I could think of to understand the process since this was my first investment. Pierre never seemed frustrated at my questions and took time to seriously explain everything and even followed up by email and whatsapp regularly.
Overall, Proper API exceeded my expectations. They provide an all-encompassing service that makes property investment seamless and stress-free. I would absolutely use their services again in the future. Highly recommended!
Note of advice to anyone using their services: buying a property takes a bit of time and patience. Things do not always move as fast and some things go really fast. So keep this in mind!
I am having a great experience with Proper API team as my guide towards wealth building and tax saving strategies. My advisor, Lukas, is very professional and experienced with his insights and has helped choose the right options for a long term financial plan. Highly recommended!!!
I lost a key and requested an insurance claim. They helped me contact with the insurance company for the claim. It was smooth.
Very competent and flexible account management. I can only recommend. Communication is also top notch!
Very nice service so far. I'm in the process of buying a flat with them and they have been very helpful, explaining me all the stages of the process as many times as I need to understand. Also they are organizing all the appointments so there is really not so much for me to worry about.
Great team and professional financial services from Proper API & Christian particularly. I really appreciate the time and effort they put into this and how helpful they have been.
I highly recommend them.
Working with Proper API has been a truly positive experience. Their communication was clear, prompt, and highly effective throughout our collaboration. They took the time to understand my needs, providing advice that was both insightful and easy to follow. I am very satisfied with the service provided and am looking forward to working with them again in the future.
Proper Api has been super helpful in tailoring a financial plan for myself based on my needs. I have been working with them for over a year. I found their expert team to be knowledgeable, supportive and professional. Would recommend them.
I had an excellent experience with this service, particularly thanks to Andre, my financial expert. He explained everything in detail about private health insurance, private pensions, real estate, and other types of insurance. Andre was thorough, knowledgeable, and incredibly patient, ensuring I understood all aspects clearly. He also made multiple follow-up calls to address my questions and provide updates, which I greatly appreciated.
I’m very happy with the service and would highly recommend it to anyone looking for expert financial advice. Andre’s professionalism and dedication really stood out. Thank you!
I highly recommend Proper API for their exceptional financial services. Their tailored financial planning, personalized insurance solutions, and expert investment strategies have significantly helped me. The advisors are knowledgeable, approachable, and adept at tax optimization, helping me reduce liabilities and maximize returns. The comprehensive and holistic approach they take makes them a one-stop solution for all financial needs. I highly recommend them for investing in properties, optimize taxes, or secure the right insurance.
I’d also like to give a special thanks to Pierre for his help throughout the process of buying our investment properties. His expertise and support were really appreciated and made the whole experience much easier.
Thank you!
Continuous support and endless patience to explain how the products work. My two consultants were experts in their particular fields and were honest about what was in my best interest. I wanted to finally sort my pension out and get my investments started and Proper API was what I needed.
Responsiveness is 100%, qualified employees and dedicated to the company and clients.
