This session is for you if
You recognise at least three of these sentences.
- Approvals, trade-offs, exceptions: everything comes back to you.
- Your team waits for your green light to move.
- You invest 20% more, and revenue only grows 5 to 10%.
- Your numbers stay below your projections, quarter after quarter.
- Four or five projects run at once, and none really moves.
Not for you yet if your company makes less than €200K a year or is still looking for repeat customers.
What the session covers
Four chapters. Each one cost me dearly.
For each mistake: what happened at Sortlist, what it cost, and what I'd install today to avoid it.

Pricing under pressure
How a business-model switch can cost you control of your margin.
3
Expansion
Replicating across markets without replicating the chaos.

The FounderOS GTM Cockpit, ready to fill in.
A one-page spreadsheet. Six stages, from acquisition to winning back lost customers. For each lever: the metric that judges it, its target, its red line and its owner. The green, amber or red status calculates itself.
In Excel (works in Google Sheets), with a filled-in example. Handed out at minute 75, before the questions.
Who's speaking
Thibaut Vanderhofstadt
Co-founder and CEO of Sortlist for 11 years, from a university project to a European B2B marketplace. The wins, and the mistakes: a failed Series A, a pivot that cost me control of the margin, a restructuring.

“A hard worker like I've rarely seen: he gives 100% to his project and knows how to surround himself with talented people. A CEO who combines genuine humanity with sharp analytical rigour and a customer obsession. He brings out the best in everyone.”
Olivier DanniauEx-CCO of Sortlist · Founder @ Sparkway
“What struck me most was how involved he was, strategically and humanly. After a conversation with Thibaut, people walked away more motivated, more aligned, with a much clearer view of where the company was going.”
Cristian IordanFounding Product Designer @ Lette.ai · 5 years at Sortlist
“What stands out is his genuine availability and his commitment to building something meaningful — not just for the business, but for the people around him. A real ability to bring out the best in his team.”
Alexandre Le ClercqSenior Business Developer · B2B SaaS
