About Marie

Your clients love you. Your team is moving forward. And yet... you still spend your weekends on billing.

Don't worry, you're not alone. This is the daily reality for most of the leaders I meet. It's not a lack of skill: they simply haven't found the right person to delegate what should no longer fall on them.

━━━━━━━━━━━━━━━━

👋 I'm Marie, founder and director of ML Assist. I help law firms, trust companies, medical centers, SMEs, and freelancers regain control of their time.

━━━━━━━━━━━━━━━━

🔧 WHAT WE HANDLE:

▸ Finance & billing: issuances, follow-ups, reconciliations, reporting
▸ Human resources: recruitment, on/offboarding, social secretariat interface
▸ Tools & digital: audits, CRM, automations
▸ Trust companies & auditors: quality review, AML & UBO compliance, engagement letters

And all your operational support: executive assistance, fleet management, concierge services, event planning, communication.

━━━━━━━━━━━━━━━━

📌 MY PROMISE IN 3 POINTS:

One point of contact, multiple expertise behind the scenes.
A monthly subscription. No hourly billing. No surprises.

━━━━━━━━━━━━━━━━

🤝 WHY TRUST ME?

About twenty leaders trust me to structure their operations, each with their own constraints and pace.

My job: to ensure everything runs smoothly in the background while you move forward. I like well-organized files, infallible procedures, and invisible operations because they are perfectly managed.
