Keep the website on exit. No buyout fee.
What's inside
End the partnership at any quarterly review after the foundation year. We ask for 12 months because real booking growth takes a full season to show.
If qualified traffic comes to your site but bookings do not improve within 90 days of launch, we keep implementing fixes until they do.
At no additional cost.
Most agencies promise a website. We promise the outcome you actually care about: more bookings.

From scattered offers to one signature transformation. We rebuilt Maja’s website around the work she’s truly called to do: embodied identity coaching for women at a turning point. Built in three languages, with copy that finally sounds like her.

The Person Behind the Work

📍 Currently: Barcelona
I embed with retreat centers around the world to build the digital systems that fill their spaces. Not from a desk in Brussels. On the ground at your property, in your morning meeting, sitting with you over strategy.
I grew up with two coaches for parents. I lived in a co-living for over two years and it genuinely changed my life. I'm building TransformWebsites partly because I'm learning from every retreat center I work with, on my way to one day building my own.
“If I can give back time to practitioners, so they can focus on transforming people, then this is everything.”

Questions Worth Answering
Real booking growth takes a full season to show. Retreats run on yearly cycles. SEO compounds across months. Conversion experiments need real data volumes. We ask for the year because that is when meaningful results become visible. After that, you stay or leave on your terms.
Most agencies charge a fixed monthly retainer whether you book one guest or a thousand. With us, when bookings dip, our fee dips with you. When you grow, we grow with you. And the 3% steps down to 2% above 500K EUR in annual bookings, and to 1% above 1M EUR. We are not maintaining your site. We are invested in your numbers.
The 299 EUR minimum applies. That covers our baseline cost of keeping your platform running. In busy months we earn together. In slow months we both have a floor. That is the partnership.
If qualified traffic comes to your site but bookings do not improve within 90 days of launch, we keep implementing fixes until they do. At no additional cost. That is the Booking Guarantee, and it applies while you are on the partnership.
WordPress is fine for simple sites. For high-converting booking experiences with custom Stripe checkout flows, Next.js gives us speed, security, and full control. No plugin conflicts, no slow loads, no security patches every week. Just a foundation built for performance.
20 days is already 4 to 8 times faster than traditional agencies. The timeline gives us room for the strategy work, the build, and the review cycles. Rushing compromises conversion quality. The goal is not a fast website. It is a converting website.
