Motivated by the success of our customers:
The concept behind

Any business that wants to win new customers first has to attract their attention first - and reviews and ratings from satisfied customers are the best way to successfully market your services. We support companies of all shapes and sizes and enable them to present their work and success in an authentic way by utilizing feedback from their satisfied customers - and increase revenue as a result. An internal survey we conducted shows that our customers have been able to increase revenue by an average of 10% through using ProvenExpert.

9 out of 10 consumers check personal recommendations from friends by comparing them with reviews and ratings online. This is true for both products as well as services in all business sectors. Referral marketing is now a hugely important factor for success, as referrals have a cross-sector effect and are a more sustainable driver of new business than self-promotion. A growing number of Germany's four million companies are beginning to recognize the untapped potential of actively collecting feedback and leveraging this potential to push their businesses to new heights.

But only one in ten service providers actually uses referral marketing to their advantage. Many simply lack the time, experience, or knowledge to effectively collect reviews and ratings and put them to use as marketing materials. And that's where ProvenExpert comes in: we make successful referral marketing simple.
Even ProvenExpert itself leverages the power of feedback to successfully attract new business.

Strong partners.
Powerful services.

With BELLEVUE Investments GmbH & Co. KGaA and renowned, experienced investors on our side, we benefit from the comprehensive support of our partners to push our services to new levels.
