Context

I joined OnePivot at a very early stage, when the product vision was strong but GTM, positioning, and scope still needed to be defined.

The goal was to translate an ambitious idea into a clear offer, a focused MVP, and real market signals.

My Role

Founding Growth & GTM execution.

What I Did

  • β€’Clarified positioning, target audience, and core narrative
  • β€’Defined MVP scope and product priorities aligned with GTM
  • β€’Shaped UI direction and messaging for clarity and confidence
  • β€’Built GTM assets: website, landing pages, messaging, lead capture
  • β€’Ran paid acquisition experiments (LinkedIn & Meta)
  • β€’Implemented server-side tracking to measure real signal, not vanity metrics

Outcome

  • β€’Clearer positioning and offer definition
  • β€’Accelerated strategic clarity around market fit and next steps

Testimonial

"I worked with Antoine at a very early stage, when the GTM strategy still needed to be defined.

He led the early growth and marketing strategy, translating the product vision into clear positioning, MVP scope, UI direction, and concrete GTM assets.

The sprint significantly accelerated clarity around market fit and next strategic decisions."
