FAQs

Who is The Founder Protocol for?

You’re a B2B startup founder who:

  • You’re a B2B founder doing €0–50K monthly revenue.
  • Your ICP, positioning and messaging needs to be clarified.
  • You are stuck with lead generation that doesn’t convert.
  • You’ve built the product but revenue isn’t predictable.
  • You want a sales engine, without hiring a sales team yet.
  • Wants clarity, focus, and scalable acquisition systems
What is the problem you solve for B2B startup founders?

Let’s be honest. Most founders:

  • Waste 6–12 months trying to figure out sales and GTM.
  • They sometimes also burn money on freelancers, ads, or playbook PDFs.
  • They build features nobody’s paying for

Result? Stagnation. Burnout. No predictable revenue.

I coach founders with a precise GTM and Sales system that enables them to go from $0 to $1M in annual revenue within 12-18 months. My mission is to bring clarity and clear methods that they can rely on to scale to their first million in annual revenue.

Why it works?

This isn’t theory.
This is the exact system I’ve used with B2B founders to go from “crickets” to consistent cash flow, without sales hires, or burning out.
If you’ve got a real product and real ambition, this gets you real revenue.

I have learned and perfected it while achieving $500 to $65M in ARR at Algolia, as well as with my own startup Terality, then building the GTM engine of poolside.ai, and with over 50 founders as a coach over the past three years.

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.

In 2024, I joined the founders of poolside.ai to create the GTM motion, and help raise the $500M Series B.

I left poolside at the end of 2024 as the team was in place, to focus again on helping several founders setup and improve their GTM & Sales.
