HOW I WORK
Work with me
High-touch GTM and sales coaching, adapted to every founder, B2B company, market, stage and current bottleneck.
Every startup has a different product, market, founder, sales motion and constraint. The principles are repeatable. The decisions are not.
I use proven frameworks and systems, then apply them with you to your specific company and situation.
WHAT WE WORK ON
Advisory
Diagnose the commercial bottleneck. Make better strategic decisions. Choose the right priorities. Design GTM and sales systems.
Coaching
Improve founder sales skills. Prepare for difficult conversations. Stay focused and accountable. Build confidence through repetition and feedback.
Ongoing support
Work through real situations as they happen. Review messaging, deals, hiring decisions and GTM experiments. Adapt the plan as new information appears.
I work directly with the founder: high-touch, candid, practical and personalized. There are no junior consultants and no generic curriculum.
The goal is not to make founders dependent on advice. It is to make them better operators.
FOUNDER PERSPECTIVES
“Working with Guillaume was incredible for both me and the company. It helped me transition from a founder who knew some sales to one who was confident as a salesperson and later on sales leader. Guillaume also was key in crafting the right sales process for us. His expertise helped us go upmarket, close the first clients, allowing us to close significantly larger opportunities. He also greatly contributed in the recruitment of our first hires in the sales team. All in all, Guillaume was a game-changer for our growth!”

Eiso Kant
Co-Founder of poolside.ai (exit to Nvidia)
“Guillaume is a beast. Over four years at Algolia, he was our top-performing Enterprise sales manager, consistently crushing quota and leading strategic deals. He successfully designed and closed our largest and most critical contracts across mid-market and Enterprise segments.”

Nicolas Dessaigne
General Partner at Y Combinator; Co-Founder of Algolia
“Guillaume is the GOAT! The best decision that I ever took as a founder was to work with Guillaume. Not only he's truly an amazing human being, giving energy and intensity in every call and messages, but he's also committed to truly understand your product and help you shape the sales strategy on the long run. His experiences have been more than valuable and clearly there is a before and after when you're working with him. In the first call with him, he opened the pathway to understand how to make our company scale the first 0-1M while setting up the stepping stones for the next milestones. Can't recommend enough as a technical founder."

Roni Carta
CEO & Founder of Depi.security
“Guillaume helped us compress what would have taken a full year of trial and error into just a few months by implementing the right process and tactics. He guided us all the way to the €1M milestone. That included structuring our sales engine, improving how we prioritize, and helping us recruit the right people at the right time. He delivered on his mandate: take us to €1M.”

Boris Toledano
Co-Founder of Linkup.so
"Guillaume has played a key role in building the foundations of our sales org and taking us to €1M ARR. Not only was he a demanding coach who helped me significantly improve my sales skills, but he was also a sparring partner on all my GTM topics (recruitment, pricing, etc.). I recommend him to any ambitious founder who wants to put their business on the path to success."

Ferdinand Terme
CEO & Co-founder of Pletor.ai
“Guillaume has been invaluable for helping us structure our commercial approach & creating a scalable, repetitive, predictable sales process. Since we worked together our deal size grew 4x, our messaging resonates better and we are closing customers faster. Beyond the companies growth, Guillaume helps cutting through the noise of fast-changing priorities and his advices have helped me grow as a founder. I recommend Guillaume to every founder that is looking to crack the PMF and upgrade their sales game.”
