The Challenge

You're growing faster than your foundation.

The gap between where your business is and what the foundation beneath it can actually support — that's where things break. And it almost always shows up at the worst possible moment.

We come in at the specific moment when the foundation needs to be built — and we build it alongside you.

You're stitching together numbers before board meetings.
Finance hasn't been built — it's been improvised.
Burn is unclear or creeping up.
No real visibility. No rolling forecast. No plan.
A transaction is coming — and the foundation isn't ready.
The cost of being unprepared at that moment is high and often irreversible.

What Makes Us Different

Operator-led. Not advisory.

Hands-on operator experience — not advisory distance.
We've built finance and operations from inside fast-moving companies, not from a consulting deck. We sit alongside your team, own the work, and do what it takes to get the outcome.
Finance, operations, and people — one engagement.
Most fractional support covers one function. We cover all three — financial infrastructure, operational build, and team development. No gaps between them.
The capability stays when we step back.
We build your internal team alongside the systems. When the engagement ends, your people can sustain what we built — and your next hire steps into something that works.

About

An operator who has built from the inside.

I've spent 15+ years building and running finance and operations inside companies that were moving fast — from early-stage startups preparing for their first institutional raise to established businesses navigating complex growth and transition. I've sat in the room with founders and boards, owned the numbers, built the teams, and done the work that made the next stage possible.

My background includes experience at Deloitte, EY, and The Hackett Group, as well as operating roles within VC-backed companies from Series A through Series B. I know what the foundation needs to look like at each stage because I've built it, not just advised on it.

I started this practice because the gap between what founders need at critical moments and what the market actually provides is real — and I've been on the other side of it.

What Founders Say

Results from the room.

"As we were preparing for our next raise, I needed more than a finance person — I needed someone who could build the operational and financial infrastructure of the company from the ground up while we focused on product and growth. Olivier did exactly that. He built the finance and operations function from scratch, developed a team that could execute, and led the work that made our successful $12M raise possible. He was a true partner — in the room, doing the work, and thinking several steps ahead."

"Through a recommendation from a trusted mentor, I engaged Wave 3 to help refine my vision for the business and ensure we had the right processes and financial controls in place to support our growing operations. Olivier and his team conducted a comprehensive assessment, developed a detailed set of recommendations, and partnered with us to implement them. They were also instrumental in helping us secure the capital needed to expand. I highly recommend Wave 3 to any business owner looking for a trusted partner to take their business to the next level."
