STS Strategy · Sharper moves.

Commercial strategy that pulls the market toward you.

Fractional and interim commercial strategist for founders, family businesses and private equity.

Sales, marketing and business development aren't pulling the same line. The pipeline is reactive. I help founders, CEOs and commercial leadership break that pattern.

Five years CCO and CBDO at The Onemeeting Company: +32% revenue, +47% EBITDA. Pre-opening CCO Maloba Private Game Reserve: commercial infrastructure from concept to launch with USD 2M pipeline in four months.

01 · Who I help

Three patterns. Which one is yours right now?

My revenue is growing, but margin is not.

Top-line looks healthy on the board slide, but EBITDA is not moving with it. Pricing doesn't quite fit, the business mix is drifting the wrong way, and each euro of revenue costs too much to land. Growth, but not the growth you want.

→ Strategy Sprint

Sales, marketing & BD don't understand each other.

Three departments, three dashboards, three truths. The pipeline leaks between stages, leads come in and sit. Nobody owns the full commercial process. Sales, marketing and business development move independently in the wrong directions.

→ Fractional or Interim Lead

The board deserves a sharper story.

The common denominator for an exit, the next supervisory board meeting or conversations with a new investor: the commercial narrative needs to hold, even under hard questions. Assumptions you can underpin, weak points tackled in time, numbers that speak for themselves.

→ Board & Investor Prep

Also for private-equity funds buying senior commercial diagnostics or interim leadership for portfolio companies.

02 · How fractional works

Senior commercial leadership. One to three days per week.

Six to eighteen months. Full accountability inside scope.

What fractional is

Senior commercial leadership in a part-time form. Full accountability inside the agreed scope. High trust, high performance. Standard internationally in scale-ups (US, UK). In the Netherlands breaking through hard since 2023.

Why it works for scale-ups

Below €20M in revenue, your business does not yet justify a full-time CCO. Above €5M, you do need senior commercial thinking. Fractional fills that gap. No €250k+ base salary. No interim-agency rate of €1,800 per day. Instead, a senior practitioner helping you build, part-time.

How it differs from interim, consultancy and agency

  • Interim: a temporary full-time replacement. STS offers this as well in Fractional or Interim Commercial Lead, but it is a different format from fractional.
  • Consultancy: sells process and a deck. STS delivers decisions and ownership.
  • Agency: executes on brief. STS thinks, chooses, and steers.

When fractional does not fit

For small teams (fewer than ten people) without commercial cadence, operational firepower is often more valuable than a senior strategist. The same is true for organisations looking for "a few extra hands" instead of direction, or founders unwilling to give away mandate.

03 · What I do

Three formats. Scope up front. One sharp proposal within 24h.

01

Strategy Sprint

3 to 4 weeks · fixed price

When

Commercial direction needs to be sharp ahead of a board meeting, funding round, leadership change or market move. You're looking for more than an advisory report to really challenge or validate plans you already have.

Scope

Diagnostic of pipeline, pricing, sales-marketing alignment, and commercial team structure. One readout document. One working session. Going into the operational touchpoints with depth.

Out of scope

Execution, hiring, agency work.

€8,500 – €15,000 Indicative
02

Fractional or Interim Commercial Lead

3 to 18 months · retainer or day rate

When

The commercial seat is empty, half-full or overstretched. The board wants senior thinking without searching for a full-time CCO yet, or wants exactly that, a full-time CCO for a defined period to pull things tight.

Scope
Mode A · Fractional cadence 1 to 2 days per week, 6 to 18 months. Board input plus pricing review, pipeline cadence and go-to-market (GTM) choices & planning.
Mode B · Interim full-time 4 to 5 days per week, 3 to 9 months. Full takeover of the commercial seat.
Out of scope

People management under leadership layer, hands-on selling, ops bloat.

€6,000 – €9,000 / mo Fractional · interim on request
03

Board & Investor Prep

2 to 6 weeks · fixed price

When

Pre-funding, pre-exit, pre-board meeting. The commercial story has to hold under extreme pressure. For when you really want to pressure-test it in advance.

Scope

Sharpen the commercial narrative, define defensible metrics, expose the weak points, fix them and do two rehearsals. Hands-on approach, taking a devil's-advocate role to challenge your board, leadership or MT.

Out of scope

Financial modelling, legal work, M&A advisory.

€5,000 – €12,000 Indicative
04 · How I work

How I think, before I advise.

01

Decompose

"Our sales is under pressure" is not a problem, it is a symptom.

Is it intake? Stage conversion? Deal size? Cycle length? Each layer is a different conversation.

02

Make it explicit

"We need more leads" is almost never the real problem. Often the leak sits between marketing qualified lead (MQL) and sales qualified lead (SQL).

Then the move is not more intake, it is better qualification.

03

Separate assumption from fact

With every recommendation I show what I know, what I assume, and what I still need to test.

No false certainty when we are talking about money and investment.

04

Verify

The market always has the last word.

Internal conviction gets tested against customer behaviour, not against meetings, not against sales.

05

Define

One recommendation you can act on immediately. And one alternative if it lands materially differently.

Not five options for you to weigh on your own.

Speed over consensus. Logic over politics. What works in the real world, over what sits in the deck. The goal is sacred.

07 · About Kevin

Kevin van Grondelle. Founder STS Strategy.

Kevin van Grondelle

What I do for you: ask the question no one else at the table is willing to ask. Surface the assumptions the commercial story is leaning on. Pick the next move you would still stand behind six months from now.

Entrepreneur from a young age. Five years CCO and CBDO at The Onemeeting Company, four of those as statutory director of Onemeeting.com B.V. and three as a member of the Executive Committee (ExCo). Strategic counterweight to the CEO, custodian of shareholder interest, and the voice in the boardroom that plays devil's advocate when consensus comes too easily.

Recently active for Maloba Private Game Reserve, currently advising the Sales Management Association and D&B The Facility Group. Three different sectors, one thread: building commercial infrastructure where none stood, and sharpening existing infrastructure where it sits loose.

STS Strategy started in November 2025. The reason is simple: there is a gap between what a large consultancy delivers and what a founder or CCO actually needs. Decks are not decisions. Four juniors do not add up to senior. An agency is not a sparring partner.

What STS Strategy is: one person, operator-deep, with commercial seat time. Senior. Solo. No team in tow. Twenty to thirty hours per week, deliberately small.

What STS Strategy does not do: volume coaching, agency execution, full-time exec roles outside an interim context, physically location-dependent work. That boundary is not tone. It is positioning.

08 · Frequently asked

What founders, CEOs and supervisory boards ask first.

What does a fractional commercial strategist actually do?
A fractional commercial strategist takes the senior commercial seat part-time, with full accountability inside the agreed scope. Not a coach, not a consultant carrying a team. I sit at the table with founders, leadership and supervisory boards, sharpen pipeline, pricing and go-to-market (GTM), bring sales, marketing and business development onto one line, and make sure the commercial story for the board or investors stays standing when the hardest questions get asked.
How is this different from an interim manager, a consultancy, or an agency?
A large consultancy sells process. You pay for a team, receive a framework and a deck, and stand alone again on Monday. An interim manager is a temporary full-time replacement, often late to the seat and deliberately short-term. An agency executes what you ask, not necessarily what is needed. STS Strategy is none of those three. What you get: senior commercial judgement with ownership, one person at the table, at the cadence your stage requires. No team, no framework factory, no waiting for the right day of the week.
When does this make sense for my company?
For B2B scale-ups and mid-market companies roughly five to fifty million euro in revenue, NL-based or NL-active, where the top-line grows but the coherence is missing. Sales, marketing and business development pull in three directions, the pipeline is reactive, the next board meeting asks for a sharper story. In addition, I work with private-equity funds looking to commercially accelerate a portfolio company or prepare it for exit. Less suited to pre-seed, or to enterprises with a full commercial stack already in place.
What does it cost and how long does it run?
Three formats. 1. Strategy Sprint: three to four weeks, indicative €8,500 to €15,000 fixed fee. 2. Fractional or Interim Commercial Lead: three to twelve months, fractional €6,000 to €9,000 per month, interim full-time on day rate. 3. Board and Investor Prep: two to six weeks, indicative €5,000 to €12,000. One sharp proposal, fast. Every engagement starts with one 30-minute call.
Do you work solo or with a team?
Solo by design. Twenty to thirty hours per week go to client work, deliberately small. No analysts, no junior consultants, no overhead. You get me at the table, not a team building a deck about what you already know. That also means I am selective about which engagements I take and how many clients I run in parallel.
Do you take full-time interim roles or only fractional?
Both. Fractional is one to two days per week for six to eighteen months, with board input plus commercial steering on pricing review, pipeline cadence and GTM choices. Interim full-time is four to five days per week for three to nine months, full takeover of the commercial seat. Interim is priced on day rate, on request.
Do you work with companies outside the Netherlands?
Yes. The base is the Netherlands, working languages are Dutch and English, and part of the work runs with internationally operating companies. Location matters little, the quality of the commercial question does.
What do you not do?
No volume sales coaching, no agency execution, no content or lead-gen as a service. No full-time exec role outside interim context. No financial modelling, no leading due diligence, no M&A advisory. No physically location-dependent work. What I do is bring senior commercial judgement to the room where the decisions get made.
