About Juliette

I help B2B SaaS companies increase conversion, reduce funnel drop-off, and grow qualified pipeline through structured experimentation and data-driven optimization.
With 6+ years at companies like Justworks and ADP, I've built and scaled A/B testing programs from scratch (500+ experiments), owned full-funnel CRO strategy, and delivered measurable revenue impact across acquisition and activation journeys. I work closely with Product, Engineering, Design, and Data teams to move fast and make decisions that stick.

What I typically help with:
  • Experimentation programs — building or scaling A/B testing roadmaps
  • Funnel audits — identifying drop-off points and prioritizing fixes
  • Conversion strategy — landing pages, onboarding flows, acquisition journeys
  • Analytics & measurement — KPI definition, tracking QA, dashboard setup

I also leverage AI tools to streamline workflows, automate reporting, and accelerate testing cycles — helping teams do more with less and focus energy on high-impact decisions.

I'm based in Munich and available for remote freelance and contract engagements across Europe. Fluent in English and French.
