One of our SaaS clients approached us, requesting a redesign that could potentially double their conversions. They had a decent number of sign-ups, but hardly anyone was progressing beyond the first day. One of the simplest user research techniques we employed was to conduct user interviews with their power users and understand their problems.
Instead of only talking to engaged users, we also conducted interviews with churned users - unlocking a goldmine of value. We then used these insights to rebuild the onboarding process, adding questions to the onboarding flow and adapting the user journey from there.
The results were immediate: Activation rates doubled, retention improved, and free-to-paid conversions jumped from a mere 6% to 13%.
For SaaS teams that really want to understand how to approach a redesign, the simplest technique would be to talk to their users (especially those who leave on Day 1). They often point out issues you'd never see otherwise.
