# How a B2B AI SaaS lifted MRR by 31% and cut churn by 24% in 90 days > How we lifted a B2B AI SaaS's MRR by 31% and cut churn by 24% in 90 days: a rewritten value proposition, faster onboarding and a redesigned feature page. URL: https://viesigners.com/en/product-design/b2b-ai-saas-case-study/ Last updated 2026-10-24 Steady traffic, but revenue was leaking through poor free-to-paid conversion and high onboarding churn. By re-aligning the value proposition, shortening time-to-value and redesigning a key feature page, we delivered measurable growth within weeks. ## At a glance - Client: a B2B AI SaaS in game design (name under NDA). - Problem: poor free-to-paid conversion and high onboarding churn. - Results: +31% MRR in 4 days, −24% churn in 90 days, +30% feature-page conversions in 4 days. - Execution: 100% senior, by co-founder Jean-François (Toptal Top 3%). ## From leaking revenue to +31% MRR - **+31%** monthly recurring revenue (MRR), 4 days after launch - **−24%** churn in 90 days, up to −40% on key user segments - **+30%** conversions on the core revenue feature page, in 4 days ### The problem Steady traffic, but revenue was leaking through poor free-to-paid conversion and high onboarding churn. - Value proposition mismatch: the homepage talked about complex features instead of the concrete outcome, so visitors left within seconds. - Slow time-to-value: a steep onboarding curve kept new sign-ups from reaching their first "Aha!" moment. ### What we did 1. **Re-aligned the value proposition** — We rewrote the homepage messaging around what the product does for its users and handed restructured mockups to the dev team to cut drop-offs and speed up free-to-paid conversion. 2. **Accelerated time-to-value** — Iterative UX/UI mockups simplified onboarding and the core feature interfaces. New users reached their first "Aha!" faster: more free-to-paid conversions and up to 40% less churn on key segments. 3. **Redesigned the high-intent feature page** — We analyzed behavior data on the main revenue page, found the drop-off points and delivered CRO mockups in 3 days. The dev team shipped them the next day: +30% conversions in 4 days. > Their unique insight and experience into what makes great UX/UI, how to A/B test all aspects of our landing page, fine-tuning our lead gen funnel, have all contributed greatly to the success we are enjoying today. I highly recommend their agency! > — undefined 100% of the UX/UI redesign and CRO strategy was executed directly by co-founder Jean-François (Toptal Top 3%), with no delegation to junior staff. ## More great SaaS results - Assassin's Creed Odyssey: UGC platform — Quest Creator UX · 10M+ users - "Collections": Musée de la civilisation — 54,000+ archives · OCTAS finalist - Meccano's Builder/Controller Hub App — 500K+ downloads - Pharmy: clinical trial search platform — +48% conversions - "Trouve un stage" — SaaS launch · Osentreprendre winner ## What SaaS clients say > In the few words this space allows me, I can say that Charles-Érick’s support went far beyond my expectations.
