Big news: I'm officially a (late) co-founder of JobRunr 🚀

A year ago, I joined as Head of Growth. 

The deal with Ronald? 

Date for one year. If the spark is there, we make it official. 💍

We negotiated everything upfront so we could spend the rest of the year focused on one thing only: healthy growth.

End of last year, the verdict was in.

Both of us felt it. 

This is it.

Looking back, it almost feels like a roads led here.

👉 My first startup Plann3r with Ruben Meul? We coded the entire back-end in Java. (JobRunr is a tool built for the Java world.)

Now my Java background helps me understand the product and follow dev conversations.

👉 Then I co-founded GrowForce with David & Amaury, where I led all B2B marketing and learned how to do B2B sales.

My marketing skills let me translate technical stuff into language their managers also get.

My sales experience helps me navigate corporate procurement.

And my entrepreneurial drive lets me co-create JobRunr's strategy and vision.

And if that was not enough, JobRunr's values completely align with my own. 

Everything we do is with the intention to leave the planet better than we found it. 🌍

Thanks Dirk for setting up that first date. 💚

I thought my content was driving revenue. But I couldn't prove it. 🤦‍♂️

If you market to developers, you know the pain: 
Ad blockers, Privacy extensions, "Do Not Track" headers.

And I totally get why people are using this.

I knew our blog posts were working because sales prospects kept mentioning them. 

But my HubSpot dashboard? It was a ghost town of unassigned attribution. 

Thanks to my background in Growth Marketing, I wanted hard data, not just "gut feeling."

So, I tried to build a manual map.

The Setup:
- Google Sheets: To list every closed deal.
- HubSpot Breeze: To see company-level page visits.
- Scarf: To track open-source package usage.

The Failure: 
It was a mess. HubSpot Breeze didn't talk to the Deal view. Scarf data lived on an island. I spent more time copy-pasting rows than analyzing them.

So I wanted something more efficient. 

I wanted to be able to ask: "Hey, for all deals closed in January, which blog post was visited the most?"

So I just Vibe Coded it this afternoon.

I built a custom MVP that aggregates: 
✅ HubSpot Deal data 
✅ Website traffic (even the anonymous stuff) 
✅ Scarf package downloads

Now, I'm able to ask questions like: "Show me the user journey for Deal X." "What common technical docs do closed-won deals read?"

It’s super basic (for now), but it works. 

I believe this is where marketing ops is going. 

We aren't just using software anymore; we're glueing it together with AI to get to the exact insights we need.

👇 Question for the builders: Has anyone else used Vibe Coding (or cursor/replit) to build their own internal marketing tools?

And if you target devs... how are you solving the attribution black hole?

Your app is not the future of customer experience.

I was interviewed last week by Claire Charlier who's building ENGIE's future CX vision.

One question stuck with me:

"What's the biggest misconception companies have about customer experience?"

My answer: They're still too obsessed with their own channels.

The best customer interactions happen where your customers already are.

WhatsApp. Messaging apps. Maybe even an AI that calls them 10 seconds after signup.

Not another app they'll forget to open.

Here's the shift I see coming:

Soon, customers won't interact with companies directly.

Their personal AI will.

"Siri, switch me to an energy provider that matches my values." Done.

Sure, some people will just ask for the cheapest option.

But many will want their spending to reflect who they are and what they believe in.

Their AI agent will need to understand which brands align with those values.

That's why your brand story matters more than ever.

Not just for humans, but for the algorithms that will decide on their behalf.

Thanks Claire Charlier, Steven Geerinck and Birger De Rese for the conversation,  it triggered some thinking I hadn't done before.

Excited to see what comes out of this project at ENGIE.

Marketing to Java developers is like playing the game on hard mode 🎮

And yes, I signed up for it willingly. And I would do so again in a heartbeat.

At JobRunr, our main audience is Java developers.

People with world-class BS detectors.
People who skip anything that smells like fluff.
People who want proof, depth, and usefulness. Or they are gone.

Early on, I thought classic B2B marketing would work.

Nice lead magnets.
Clean value props.
Some paid traffic.

Spoiler. It didn’t. 💡

What did work was changing how we think about marketing entirely.

👉 Treating content as documentation, not promotion
👉 Explaining the "why" behind every decision
👉 Showing the how and sharing it all transparently
👉 Brushing off my Java skills to speak the same language as our users

That mindset helped us grow an open-source project into something companies in finance and healthcare trust in production.

And now, I want help scaling that.

We are hiring an All-round Growth Marketer.

Not to "run campaign".

But to own the full journey together with me:

✅ From open-source users to paid customers
✅ From experiments on LinkedIn and Reddit to creative ABM plays
✅ From technical blog posts to simple video edits and clean visuals

This role is not for everyone.

But if you believe marketing only works when it genuinely helps people, it might be for you.

Hiring All-round Growth Marketer at JobRunr

You give a lot. You carry a lot. And somewhere along the way, you lose yourself.

Your body sends warnings — fatigue, poor sleep, irritability — but you keep pushing on willpower… until things start to crack.

I work with leaders (and their teams) who want to break this pattern.

Through data-driven insights, you uncover what truly drives you:
• Multi-day stress measurement (of your nervous system) → reveals energy leaks
• Neurotransmitter profiling → shows how your neurochemistry drives behavior
• Human Design → helps you understand your natural energy blueprint

Result: you see your patterns, understand what drives you, and learn how to perform without burning yourself out.

🔋I guide leaders who go all-in but lose themselves along the way — using multi-day stress measurements, neurotransmitter profiling, and Human Design I reveal where energy leaks and which patterns hold them back 🎯

Bedankt Lieven voor de voorbije jaren.

Voor zowel de dromen als de verwezenlijking ervan. 

Om elkaars trouwste supporter te zijn en ook om elkaar uit te dagen.

Soms moeiteloos en soms ook ploeteren in het ongewisse. 

Oprecht trots op alles wat we samen gebouwd hebben. 

Een uniek traject waarbij we niet altijd kozen voor de makkelijkste weg. 

En daarbij horen ook moeilijke beslissingen. 

Moedig dat je die stap genomen hebt. Helder.

En ik ga je inspiratie, daadkracht en rust hard missen...

Dat onze wegen op de juiste momenten mekaar nog mogen kruisen. 

Tot straks en succes met alle nieuwe avonturen. 

Aho ❤️

After a long and conscious process...


I decided to stop with Built For Endurance.

After many beautiful years, converting a joint passion into a business, Steven will continue the Built For Endurance journey on his own.  

The entrepreneurial road the past years was not easy...navigating difficult economical conditions, experiencing financial uncertainty, wearing 20 hats at the same time, balancing between what you LIKE to do and MUST do,...

So the decision was a tough one, but sometimes it's better to take a tough decision, then no decision at all.

I'm deeply grateful for all the lessons this entrepreneurial journey has brought to me, for the warm friendship with Steven and I'm sure that he will continue the mission with a lot of authenticity and enthusiasm. Our roads will cross many more times in the future.

2026 will nevertheless not be a quiet one...
- continuing in supporting people performance and change with Nova Reperta
- keynotes and workshops with Speakersbase and Read My Lips
- the launch of the English version of Fully Charged during summer, together with Kogan Page Publishing
- and some other exciting projects ahead

And soon, my new website www.lievenvanlinden.com will be online.

💥We gonna do it again. 💥

👉Olivier Vaneeckhout en ik gaan opnieuw op pad in 2026.

De weg van de pelgrim. 

In de Katharenstreek.

Tussen Bugarach en Montségur.

Bergachtig & glooiend. 

Waar eenvoud en kracht samenkomen.

Begeleid door de gieren.

Niet in mei. In oktober deze keer.

Dat geeft nog tijd om voor te bereiden.

Maar we starten nu wel al.

We gaan op stap met 7.

Op dit moment nog onbekenden.

Maar daar mag verandering in komen.

Voel je een ja?

Dan leren we je graag kennen.

Stuur een DM.

🙋Welke 𝐠𝐞𝐰𝐨𝐨𝐧𝐭𝐞 had voor jou de 𝐡𝐨𝐨𝐠𝐬𝐭𝐞 𝐫𝐞𝐭𝐮𝐫𝐧 (𝐑𝐎𝐈) 𝐢𝐧 2025?

💥Oprecht 𝐛𝐞𝐧𝐢𝐞𝐮𝐰𝐝 naar.

👇Drop in de 𝐜𝐨𝐦𝐦𝐞𝐧𝐭𝐬.

✅En als je het eens bent met iemand anders, klik dan ook op de 𝐥𝐢𝐤𝐞-knop bij hun reactie.

Nadien maak ik een lijst met de 𝐭𝐨𝐩 10 die ik opnieuw met jullie deel.

Mijn beste ROI:
😴𝐒𝐥𝐚𝐚𝐩𝐜𝐨𝐧𝐬𝐢𝐬𝐭𝐞𝐧𝐭𝐢𝐞.
> Elke dag rond hetzelfde uur naar bed.
> Elke dag rond hetzelfde uur opstaan.
Minstens 7,5 uur. Ideaal 8–8,5.

Misschien niet de meest sexy biohack.
Maar voor mij wel 𝐠𝐚𝐦𝐞-𝐜𝐡𝐚𝐧𝐠𝐢𝐧𝐠.

BEST ROI habit in 2025

Meerdere keren kwam ik het tegen de afgelopen weken.

Mannen die klagen over hun situatie.

Jobgerelateerd meestal.

Beslissingen waar ze het niet mee eens zijn. 
Shit die zij moeten opkuisen.
…

En als je lang genoeg wacht, 
hoor je daarna de andere kant van het verhaal.

“Ik verdien goed.
Het is overal wel iets.
..."

En dan de absolute killer: 

“ik heb zekerheid”

Eigenlijk is het jammer dat je niet meer pijn of discomfort ervaart, denk ik dan.

Want nu accepteer je middelmatigheid. 

Je blijft in een positie waarin je geen krachtige beslissing durft nemen.
Een beslissing die leidt tot echt significant meer levenskwaliteit, contributie & geluk.

Het kostbaarste bezit is onze tijd.
Die wordt seconde per seconde uitgegeven. 
Non stop & non-refundable.

Wil je zelf weten waar je compromissen sluit in je leven?

Stel dat je leven geprojecteerd wordt op een groot scherm.
Wat zou het publiek roepen om nu te ondernemen 

Dat kan misschien helpen om actie te ondernemen.

Zodat tijd wel goed wordt gespendeerd.

En dat de 85-jarige versie van jezelf blij kan terugkijken.
