At 359, we have a core conviction:

Our mission
At 359, we were founded on a core conviction:
The real game changer is always the same, the right person, in the right seat, at the right moment.
As a leader, you can redesign org charts, run workshops, rewrite processes, reshape strategy decks. But nothing transforms a company faster than a top-tier talent landing where it matters.
High performers change the trajectory of a business, immediately and decisively. That’s why we exist.
Our role
To bring our clients the top 1% of talents built for intensity, ambiguity and hard execution.
Profiles forged in selective environments, shaped by pressure, and driven by impact.
People who accelerate growth, fix what’s broken, with a collective mindset.
Complexity and intensity aren't constraints. They're our playground.
We thrive where others hesitate
high-stakes contexts, demanding timelines, ambiguous briefs. Because when the brief is unclear, our value is obvious.
Our clients move fast and aim high, scale-ups, industry leaders, ambitious SMBs. They trust us because 78% of our new clients come through referrals, a number that speaks louder than any marketing claim. We’re building a new generation of people company. Demanding, practical, operational.
No fluff. More WhatsApp, less inbox. Razor-sharp workflow. Decisive action. A culture of performance, autonomy and high standards. Low ego, high intensity.
Straight to the point.
We don’t fill roles. We activate decisive encounters. We create long-term fits that push companies forward.
We are here to deliver outcomes
To place high-value leadership teams who make an immediate difference.
And before recruiting ExCom leaders, we recruited the ones standing right beside the Number One.
The job we did. The job we love. The Chief of staff role.
Hiring a Chief of Staff means understanding everything: strategy, culture, the CEO’s mindset, the organization’s hidden dynamics, and the momentum behind it.
It shaped our precision, our culture, and our way of reading companies and remains at the core of who we are.
At 359, we are building an ecosystem
a circle of clients and talents who share ambition, clarity and velocity.
People with whom we want to grow, long term.
Because in the end, impact is simple: put the right person in the right place, and everything changes.
