Questions & Answers

As answered by people managing Duolingo and pre.dev.

What's the story behind your product?

pre.dev's answer:

My co-founder and I ran a boutique consulting firm and realized we were spending too much time understanding client requirements to get started on the project.

What makes your product unique?

pre.dev's answer:

We are the only end-to-end solution for planning and visually explaining how to get from an idea to reality.
