Hey Adrian, thanks for the honest feedback. Very much appreciated. Prior to building this landing page to further validate my own assumptions on the need for this type of product, I conducted some user testing and interviewed 10-12 UXers and asked them a series of questions about their current use of personas in their workflow, time allocation to them as deliverables, feedback and iteration process, and pitfalls they experience while developing them. The takeaway for me was learning that UXers value personas as a tool for driving design decisions, but would welcome a faster more efficient way to create them, a better way to share and collaborate with stakeholders and speeding up the iteration process. So that's ultimately what led me to the MVP feature set.
Obviously no product is a good fit for everyone, but if it solves a problem for enough people, its worth pursuing :)
