"The leader's solitude is not a myth: you sign alone, you decide alone, you carry the doubt alone after the decision.A sparring partner doesn't remove that solitude — it makes it fruitful.What I observe at my level: a good Sparring Partner doesn't validate, he disrupts.He asks the question you didn't want to hear, where the usual network or even the partners stay in collusion.On issues as structuring as an acquisition, an agency restructuring, or a capital arbitration, that friction is worth gold.I identify three concrete contributions:- Breaking out of circular reasoning,- Naming the blind spots (often emotional biases, not analytical ones),- And holding the course over time — because the real issues are worked through over 18 months, not in a single session.At this stage of my journey, I believe it's a discipline, not a comfort."

‘With Yannick, I learnt to break out of circular reasoning, to name my own biases and to take a step back from the development of the brand.

Our conversations are sometimes unsettling, but always constructive.

He helped me structure and build an organisation capable of absorbing growth while staying true to what sets us apart: “At BASILIC & CO, success comes through people and a demand for quality, at every stage.”

The Sparring Partner is far more than advice: it is a trusted partner who understands the loneliness of the leader and turns it into a strength.

Today, I realise just how important this support is. It allows me to stay true to my vision while giving BASILIC & CO the human and organisational resources to match its ambitions.’

‘I launched my first company with decades of experience in large corporations behind me: two executive committees, teams, budgets. In a large group, the system holds firm even when you have doubts. In a young company, you are the system.

It's not the same mindset, it's not the same relationship with risk, it's not the same loneliness.

And that is where the Leader's Sparring Partner plays a key role in the set-up: someone who knows entrepreneurship from the inside, with values that align with mine.

What Yannick brings me in concrete terms: 360-degree conversations, as operational as they are strategic. A detailed understanding of my project, and probably also of my strengths and limitations, built up over the course of our work together, almost from the very beginning. He challenges me on decisions I thought had already been made. He shows me angles I hadn't seen. He doesn't simply rubber-stamp things. We have worked on my mindset, structuring the scale-up, fundraising momentum, our commercial approach, cash-driven management, and every single problem we've come up against!

Our meetings are genuinely challenging. In the moment, it shakes you up, and afterwards I think to myself: “How on earth did we not think of that before?”

Yes, it's an investment. And it's one of the best I've made since the start of my entrepreneurial journey.’

‘An entrepreneur, but not alone in my decisions.

For Sinthylène, I chose to be supported by Yannick as my Sparring Partner.

The difference from a traditional network that helps me lift my head from the daily grind?

We don't just skim the surface. We anchor ourselves in one topic – marketing, cash flow, fundraising, processes – and work on it in depth, over time.

What it brings me in concrete terms: stepping outside my own convictions, avoiding getting locked into my decisions, and moving forward with someone who truly understands what's at stake.

And even if you have one or more business partners, it's different.

It's a real luxury – and a real strength.’
