Go-to-market partner for B2B tech founders

You bring the product. I bring the leads.

Bjorn turns founder-led sales and referrals into clear positioning, a better website, marketing campaigns and sales systems your team can run so winning customers no longer depends on you.

Traction is not yet a system

Your product has found a market. Your go-to-market has not caught up.

A sputtering rocket circling back
01

Referrals got you here

Your network and reputation created traction, but they do not produce a predictable flow of new customers.

02

Your GTM lives in your head

You know why customers buy, but the positioning, sales story and process are difficult for someone else to repeat.

03

Your story is hard to explain

The product makes sense to you, but customers do not immediately understand what it changes or why they should care.

04

Activity is not a system

A new website, campaign or sales hire will not fix growth unless the commercial building blocks connect.

05

Sales still depends on you

Opportunities move when you push them. When product or operations need you, commercial momentum slows down.

06

You refuse to rent your own growth

You want expert help, but not another black box that only works while an agency or specialist remains on retainer.

No GTM playbook required

You bring the traction. Bjorn builds what is next.

Find the missing GTM block. Build it.

Positioning, demand, sales and technology only work when they reinforce each other. Bjorn diagnoses the constraint and turns the right next move into something your team can use.

01

Diagnose your go-to-market

Clarify your ICP, positioning, buying journey and commercial constraint before spending more on disconnected tactics.

02

Build the missing pieces

Bjorn writes, designs, builds and connects the story, website, campaign, sales tool or system your GTM needs next.

03

Make it yours

You get the tools and understand the thinking behind them. Bjorn helps your team start executing, learn from real results and keep improving the system without depending on him.

One partner. No specialist relay race.

Every discipline your GTM needs. Connected by one mind.

You work directly with Bjorn from commercial strategy to execution. Nothing gets lost between the person who thinks it, writes it, designs it and builds it.

Deltares
“Bjorn provided excellent marketing services through his Startup Marketing Program while we at Deltares were developing our forecasts as a service. His contributions were crucial during this phase.

Bjorn helped us define our offer clearly and identify potential markets and clients. He was particularly agile in pointing out when certain avenues weren't successful, guiding us to explore other, more promising opportunities. He also set up a system that we now use for user acquisition. His insights and practical approach have been very helpful for us.

Bjorn is dedicated, creative, and professional. I recommend him to any organization looking to improve their marketing efforts.”

Strategy brain. Builder hands.

Bjorn Wamelink. Founder to founder.

Bjorn has been an entrepreneur since 2010. Having bought, run and sold companies, he knows growth rarely fits neatly inside one discipline.

As a fractional CMO, strategist, copywriter and digital builder, he can move from the boardroom to the browser without losing the thread. He does not just build the answer. He teaches the thinking, works through the first results with you and helps your team improve from there.

The best result is knowing exactly what to do without Bjorn.
