Subsidy Eligibility Checker
Enabled users to check whether they are eligible for subsidy, how much subsidy they can potentially receive and how.
Impact
We improved conversation rate significantly by me initiative to fully revamp our multi-step subsidy checker form.
When I joined the Viessmann venture FörderProfi, the subsidy check was a full page form that overwhelmed most users due to complexity
By splitting it up into several, manageable and progressively more complex steps, we managed to reduce bounce rate significantly.
In order to higher trust, I added trust indicators such as governmental certificate logos and increased trust through adding expectation building measures for users.
We were able to reduce drop-off and abandonment rate by adding confidence and transparency building measures such as a help button explaining difficult terms.
We were able to significantly improve user acquisition by building campaign pages and collaborating with other companies within Germany
Collaborations with other companies in Germany, that I designed a white label version of core features of our service, enabled us to generate additional funding for the venture.
