Why Should Feedbax Find My Service Provider?
Finding the right provider for your project can be a real challenge.

We know how much time and effort this costs. To illustrate this, here is a typical process:

  • Search numerous provider profiles and read reviews.
  • Analyze references and gather information about teams and prices.
  • Check websites in detail and contact providers.
  • Describe your requirements over and over again and get offers.
  • Gather and compare at least 10 offers to make an informed decision.

That sounds time-consuming and requires expertise in the selection process? That's right – and that's exactly the work we take off your hands!

  • We have years of experience and an extensive network of verified providers.
  • Our optimized selection process allows us to quickly identify the best partners for your project.
  • We guarantee you significant time savings because we take care of the research and pre-selection.
  • Only providers that meet our high quality standards will be proposed to you.
  • We make sure that the providers fit your budget and avoid overpriced offers.
  • Your individual wishes and conditions are the focus of our selection.
  • Benefit from our experience in hundreds of successful projects and our large network.
  • Our service is completely free of charge for you as a client, as we finance ourselves through the listing fees of the providers listed.

Our service for you:

  • Targeted invitation of suitable providers that meet your requirements.
  • Careful review and collection of offers so that you can keep track.
  • Procurement of 3 suitable providers that offer the highest motivation, the necessary expertise, availability and a budget-compliant offer.
