I found Brender to be a fun, playful, intuitive and well-guided way to build (or validate) your brand.
The balance between questions, suggestions to select from and insights you get seems very well thought of, and what you get (Brand ideas, logos, a market analysis etc.) and the quality of the results, for such a small effort surprised me.
I used Brender after-the-fact to validate the strength of the name, brand tone and the competitive landscape for an app I am working on. I was surprised by the smooth guided process and the intelligent and accurate suggestions the Brender made. The UX is great and creating or validating your brand and getting great feedback on your idea becomes fun.
