Growth leadership
for the AI era.

Fractional CMO and CEO for scale-ups and mid-market companies that need board-level thinking, AI-native strategy, and someone who actually builds, not just advises.

Let's talk

The gap between ambition and execution

Most scale-ups hit a ceiling. You have a solid marketing manager or head of marketing, maybe even a small team that's doing good work. But there's no one connecting marketing to the boardroom. No one translating commercial strategy into a plan that actually moves revenue.

And then there's the AI question. Every board is asking it, every team is experimenting, but very few companies have someone in leadership who genuinely understands what AI changes about marketing, operations, and growth, and what it doesn't.

Sometimes the challenge runs deeper. The company is between CEOs, leaning on a CFO to keep things running, or the founder needs a sparring partner who has sat in that seat before.

That's where I come in.

Professional setting

Three ways I work with companies

Fractional CMO

I step into your leadership team as your Chief Marketing Officer, typically 2 to 3 days per week. Not as a consultant who hands over a strategy document and leaves, but as a member of your team who owns the outcome.

  • Building and leading marketing strategy at board level
  • Connecting your marketing efforts to commercial goals and pipeline
  • Integrating AI into your marketing operations, from content and personalization to analytics and automation
  • Coaching and developing your existing marketing team
  • Defining positioning, brand, and go-to-market for new markets or products
  • Bringing structure to what's working and killing what isn't
  • Reporting to the board and aligning with sales, product, and finance
Best fit: PE/VC-backed scale-ups and mid-market companies with a marketing team in place but no CMO to lead it.

Fractional CEO / CEO sparring partner

Not every company needs a full-time CEO to move forward. Sometimes what's needed is an experienced operator who can step in part-time to provide strategic direction, challenge the leadership team, and keep momentum while the company finds its next permanent leader, or decides it doesn't need one yet.

  • Acting as interim CEO for companies in transition
  • Serving as a strategic sparring partner to founders or CFOs carrying the CEO load
  • Leading the leadership team through a growth phase, acquisition, or restructure
  • Bringing commercial and operational clarity when the path forward isn't obvious
Best fit: Scale-ups between CEOs, founder-led companies ready for a different kind of leadership, or boards that want an experienced hand during a transition.

AI strategy and transformation

This isn't about tools or demos. It's about helping leadership teams understand what AI actually means for their business, where it creates real leverage, and how to move from experimentation to execution.

I work with companies that are past the curiosity phase but stuck on implementation. That means building AI into marketing workflows, rethinking how teams operate with AI as a multiplier, and making sure the strategy is grounded in what the technology can actually do today, not what a vendor promises it will do next year.

  • AI readiness assessments for marketing and commercial teams
  • Building AI-powered marketing workflows: content, analytics, personalization, automation
  • Advising leadership teams and boards on AI strategy, investment, and risk
  • Training teams to work with AI as a daily tool, not a side project
  • Separating hype from substance so you invest where it matters
Best fit: Companies that know AI is important but don't have someone in leadership who lives and breathes it.

If you're curious how I think about AI as a builder rather than an advisor, see what I'm building.

Built for momentum, not dependency

I typically engage for an initial period of 3 to 6 months, with the option to extend. The goal is always to build capability, not create a permanent seat for myself. I work embedded in your team, join your meetings, and operate as if the company were my own.

Immersion first

Every engagement starts with 2 to 3 weeks of going deep: understanding your market, your team, your numbers, and where the real leverage is.

Embedded, not external

I join your leadership meetings, work alongside your people, and take ownership of outcomes. This isn't advisory from a distance.

Focused attention

I work with a small number of companies at a time. If we work together, you get my full attention.

What I'm building

For most of 2026 I've been building Chainge, a research preview that maps how global events connect to local business exposure. The thesis is short to state and harder to prove: any global event connects to your local exposure in six steps or fewer. Chainge finds those steps.

The methodology rests on work older than most AI platforms. Mark Granovetter's 1973 paper on weak ties argued that the most valuable information travels through weak connections between different clusters, not through strong ones within them. Watts and Strogatz formalized that as small-world topology in 1998. Surowiecki and Page-Hong showed that diverse groups outperform homogeneous experts at prediction problems. Chainge operationalizes all three at scale, attaches probabilities and a 90-day verdict horizon to each prediction, then publishes the score.

That last part matters most. Most AI intelligence products pitch on capability, "we synthesize across sources." Chainge pitches on track record. First public verdicts land in W27 of 2026. Right, partial, wrong, or unclear. No retroactive editing.

I'm building it as a founder, not as an advisor commenting from the sidelines. It keeps me honest about what AI can and cannot do in operator hands. The site lives at chainge.global.

A bit about me

Open to the right permanent or interim leadership role.

Niels Langereis

I've spent 18+ years in marketing, digital strategy, and commercial leadership, moving between agency life, corporate environments, and building things from scratch. For the past several years, I've been deep in the intersection of AI and marketing, not as an observer but as a practitioner, building workflows, testing tools, and figuring out what actually works versus what just makes for a good LinkedIn post.

Until early 2026, I led the central marketing organization at Normec, connecting marketing across 100+ companies in 20+ countries. I also serve on the board of iTRACE. Before that, I had the privilege of working with some of the most admired companies in the world, including Netflix, Vodafone, IKEA, and Albert Heijn, always at the intersection of strategy, technology, and storytelling.

Alongside the advisory work, I'm building Chainge (described above). The day-to-day is different from advising. Different stakes, different feedback loop, different kind of clarity required when you're the one shipping.

I started young. While still in college I launched a social media consultancy that, within six weeks, had me on a call with Myspace Europe about their Dutch launch. That early sense of "just figure it out and build something" never left. It's the same energy I bring to AI today: less theorizing, more doing.

My philosophy

I don't think leadership is about having all the answers. It's about creating the conditions where smart people can do their best work, where decisions are made from understanding rather than noise, and where every challenge is treated as a chance to learn something.

As a manager, I'm a coach first. I care about helping people discover their strengths and turn those into something meaningful. Growth that only serves the company but ignores the people building it isn't growth worth having.

Speaking and teaching

I speak and teach on marketing transformation, AI in business, leadership, and the future of how brands connect with people. I've spoken at events for BVA, MWG, IAB, and many others, and I regularly guest lecture at universities. My sessions are built around practical insight, a bit of humor, and the belief that the best conversations leave people ready to act.

Giving back

Some of the most rewarding work I do isn't for companies. It's for people who are just getting started.

I've spent years lecturing at universities like HKU, UVA, HVA, and NHL Stenden, and I keep coming back because nothing beats watching someone make a connection that changes how they think about their career. Marketing, AI, leadership, building something from nothing; these are things I've learned the hard way and I'd rather share them than keep them to myself.

If you're a young professional or student figuring out your path in marketing, digital strategy, or AI, I'd genuinely like to help. Whether that's advice over a coffee, an introduction to someone in my network, a guest lecture for your program, or just an honest conversation about what this industry actually looks like from the inside.

For young professionals and students

I'm always open to connecting with people who are curious and driven. A few ways I can help:

  • Career advice and honest feedback on your plans
  • Introductions to people in my network who might be relevant for you
  • Guest lectures and workshops on AI, marketing, and leadership
  • Mentoring conversations; no agenda, just a willingness to listen and share

Don't overthink it. Just reach out.

What I'm thinking about

I share what I'm working through: AI and marketing, leadership in scale-ups, the changing role of the CMO, and whatever else is on my mind. Most of these start as LinkedIn posts and articles.

Agentic branding

The shortlist effect has a dark side nobody's discussing

Marzano's Shortlist Effect says brands either make the AI agent's list or vanish. The harder question is what happens once the list locks in: how a new brand reaches a buyer whose agent already knows what works for them.

AI & Marketing

From findable to summonable: Meta overtakes Google, and the story isn't the horse race

Meta is on track to out-earn Google in advertising this year. The headline reads as a rotation; the detail reads as a phase shift. The discovery layer of the open web has changed, and most of the B2B stack is sitting on assumptions that no longer hold.

AI & Agencies

If you had an agency right now, what would you actually do with AI?

When execution becomes abundant, the value of execution collapses. The agencies that survive this aren't the ones adopting AI fastest, they're the ones that relocate their value before the market does it for them.

AI & Leadership

The hidden politics of AI adoption

I sat in on an AI strategy meeting at a midsized multinational. Twenty minutes in, nobody was discussing AI. The board was discussing whose headcount would shrink, whose budget would absorb the data infrastructure, and who would sign off when the model is wrong. Nobody said any of that out loud.

AI & Leadership

The next six months are the AI bet's first real board meeting

Over half of CEOs now believe their job depends on whether AI works out. The room sounds the same everywhere: the board approved the spend, the CMO/CTO/CFO have to deliver, and Q4 will arrive faster than people are budgeting for.

AI & Critical thinking

AI can generate answers. But who decides which ones matter?

If generating content, code and strategy becomes easy, the differentiator moves toward judgment. I call this the critical-thinking-gap, and it's where the next generation will make its biggest impact.

Giving back

An industry that only hires experience will eventually run out of people who have it

After a day with students at NHL Stenden, a reflection on why hiring young talent matters more than ever, and why I hired one of them on the spot.

Let's figure out if there's a fit

Drop me a line. I'll get back to you within 24 hours and we can set up a call to see if working together makes sense. No pitch decks, no proposals before we've talked.
