Good alternative to pricey agencies

In an advisory project, I wanted to do market research with different customer groups without involving an expensive agency. We set up the surveys in-house (with our team) with this tool. The site provided useful onboarding and in general the set up is very intuitive and straight forward. At some points, we struggled with some question types and contacted customer service and we had a solution within a couple of hours. There is a lot of explanatory material on the site as well, but due to lack of time, we had rather precise questions and less time to go through it.
