About me
About me
Over the past ten years, I've crafted revenue engines & teams, and sold software for startups and scale-ups. I joined Algolia as employee number 11, second in the business team, contributed to building and developing the revenue engine from $1M to $65M ARR globally. Transitioning to Datadog enriched my knowledge of enterprise sales methodologies.
Leaving Datadog, I founded Terality, securing close to $2M in Seed funding. We've scaled to a team of 8, with hundreds of users for our data processing engine designed for data scientists.
Since early 2022, I've been dedicated to empowering elite SaaS founding teams, accelerating their growth through top-notch sales and go-to-market strategies.
