What teams are saying
Lupine is the fastest I've ever gone from URL to structured experiment ideas. What impressed me most wasn't just the speed, it was the reasoning behind each recommendation — grounded in real experimentation data, not UX best practices pulled from a blog post.
Lupine feels like a very promising platform, especially in how it visualizes experimentation and testing opportunities. I could see it being very useful for testing user experiences and quickly communicating insights to stakeholders.
This CRO platform feels like it's heading in a really strong direction. It doesn't just highlight issues, it points you towards specific test ideas, taking a lot of the guesswork out of what to try next.
While having a website that attracts clients is essential, the ability to effectively convert visitors is even more critical, and Lupine addresses this need directly. This is a solution we clearly see ourselves integrating into our workflow on a regular basis.
