No decks. No reports.
Just results on your P&L.
I don't advise. I operate. With direct accountability on your bottom line.
Do any of these sound familiar?
The funding is there. The ambition too. Execution is where it breaks down.
You have the capital, the ambition, and a board expecting results. But the operational engine isn't keeping up with the plan.
The market has shifted. Your model hasn't kept pace.
Product, marketing, digital — you know things need to move. Transforming without breaking what works is exactly where it gets stuck.
Marketing budget up. Pipeline flat.
Campaigns are running, digital spend is piling up. But none of it is translating into predictable growth.
You're scaling. Your organisation isn't.
Every quarter brings new clients and new problems. You're permanently in firefighting mode.
You're carrying everything. Alone.
Board, teams, shareholders — everyone is waiting. You need someone who has been in your shoes before. Not another report.
What I'm Not
Not a consultant
I don't produce recommendations.
I produce results.
Not a freelancer
I don't sell days.
I don't take short mandates. I commit to transformation.
Not a classic interim manager
I don't manage the transition.
I build what comes next.
My Engagements
Bottleneck Diagnostic
3 days on-site
€7,500
I come to you. I audit the P&L, operations, and teams. No questionnaire sent by email. No debrief over video call. Three days on the ground to identify the real blockers — not the symptoms. You leave with a 3-page memo: 3 bottlenecks, 3 actionable quick wins. No deck.
Operating Partner Retainer
2 days/week · quarterly commitment
€12,000/month
I join your leadership team on a part-time basis. Weekly presence in the business, direct execution on the P&L, co-piloting with the CEO or ExCom. Not an advisor who shares opinions in monthly meetings — an operational alter ego who carries the agenda alongside you. Results visible before renewal.
Transformation Mission
3 intensive months
€35,000 fixed
Marketing transformation, product pivot, digital overhaul, reorganisation — when the topic is structural and urgent. Intensive on-site intervention over 3 months. Scope defined together, fixed fee, clear commitment on both sides. No invoice surprises.
Portfolio Partner
Shared OP · bespoke
€18–22K/month
You run a portfolio without an internal Operating Partner. I work embedded in 2 to 3 of your companies simultaneously — operational diagnosis, commercial acceleration, model transformation. One point of contact for the fund. A cross-portfolio perspective. Zero overhead. The senior operational profile your companies need but can't justify hiring full-time.
Interim Executive
Full-time · 3 to 12 months
€1,200–1,500/day
You need an operational executive immediately — COO, MD, or Transformation Director. I take on real responsibility within the org chart, while you find the right permanent hire or stabilise the situation. Immediate availability.

About
Nathalie Lamri
Interim Executive | Transformation · Turnaround · Business Unit Creation
25 years driving transformations with direct accountability. As a member of the ExCom at ME Group, I led a marketing, product, and digital transformation across 18 countries: +66% revenue and +170% EBITDA. Mandated by a fund, I turned around Rackham Entertainment post-liquidation and secured its sale at ×5. At Transatel/NTT Data, I built an international business unit from scratch — €5M pipeline in under 24 months.
I don't come from consulting. I have made the decisions, led the teams, and delivered the results.

With Nathalie, creative thinking is a given — but added to that are outcomes you can measure. I have always been impressed with her energy, enthusiasm and ability to come up with innovative and creative marketing, to get inside of new trends and analyze opportunities as well as to foster collaborative thinking within a group.

Frequently Asked Questions
A consultant analyses, recommends, and leaves. An Operating Partner stays. At SilverMatter, I operate with direct accountability on your P&L — not from the outside. I co-pilot with you, make decisions, and engage teams. Results are measured against your numbers, not in a report.
When a situation can't wait for a full recruitment process. Slowing growth post-fundraise, digital or marketing transformation to accelerate, urgent reorganisation, departure of a key executive, business turnaround — these are the contexts where I step in. The rule is simple: if it needs to move in under 90 days, the timing is right.
I work directly within portfolio companies in embedded mode — not as a remote advisor. Across 2 to 3 companies simultaneously depending on needs: operational diagnosis, commercial acceleration, model transformation. One point of contact for the fund, a cross-portfolio perspective. Ideal for mid-market funds without an internal Operating Partner.
SilverMatter's fees reflect genuine seniority and direct accountability for results — not billed days without commitment. The Bottleneck Diagnostic is €7,500. The Operating Partner Retainer is €12,000/month for 2 days per week. The Transformation Mission is billed at a fixed €35,000 for 3 intensive months. Interim Executive mandates are priced at €1,200 to €1,500/day. Every engagement is scoped with a clear perimeter and measurable objectives.
A Bottleneck Diagnostic takes 3 days on-site. A Transformation Mission covers 3 intensive months. An Operating Partner Retainer is committed by quarter and renewed on results. A full-time Interim Executive mandate runs from 3 to 12 months. In all cases, first results are visible before the end of the first month.
I operate wherever the mission requires — across France and internationally. My track record spans 18 countries at ME Group and telecoms missions with partnerships across 3 continents. On-site presence is at the core of my method: I come to you, not the other way around.
