Result: better adoption and progression to the next step within the same journey.

Measurement and learning

Problem: decisions poorly supported by data at the prototype stage.

Actions: instrumentation (steps, abandonments, errors), moderated/unmoderated test protocol, task scoring grid, prioritization loop.

Result: impact-oriented roadmap with clearly resolved hypotheses after pitch.

For the startup Yaw

Onboarding and profile

Actions: reorganized header (price, surface area, location, availability), optimized gallery (lazy-load, thumbnails), persistent and contextual CTAs, “assets/equipment” blocks, trust elements (labels, 360 tours), mobile-first version.

Result: longer engagement on the page and an increase in qualified contacts.

Problem: difficult for a decision-maker to quickly compare offers.

Result: faster decisions in committee and better perceived value by B2B clients.
