The client
Afdekzeilwinkel.nl
Afdekzeilwinkel.nl is the specialist in tarpaulins, shade sails and related products. A sharply defined range, strong product knowledge, a clear audience.
Exactly the kind of brand that can excel on marketplaces – provided the foundation is right and visibility is built deliberately.
Afdekzeilwinkel.nl – sharp niche, strong assortment
The challenge
A good product doesn't sell itself
- — Heavy competition and discoverability driven entirely by performance
- — Margins under pressure from commissions and ad costs
- — Product data and integrations that had to be exactly right
- — Conversion that could rise with a sharper delivery promise
The real question was strategic: how do you build durable marketplace growth instead of revenue that only exists while the ads run?
Proof

Foundation first. Ads second. In that order.

Sound familiar?
- —Your marketplace revenue only exists while the ads run
- —Commissions and ad costs eat your margin
- —Your product data and feed are a mess
- —You depend entirely on one platform
- —Keeping everything up to date takes far too much manual work – we automate
This is exactly what we help you with
We build this system together with you. No theory - execution.
You speak directly with the team. No sales layer.
Foundation
Data quality and operations as the foundation
Beneath the visible results lies a less visible but equally important foundation:
- — Feed management at product level: integrations and product data that are correct
- — Product families properly linked on colour and size
- — Bol.com service standard continuously monitored
This discipline keeps the assortment clean, lowers returns and protects sales. Categories like tarpaulins and accessories now convert at around 9%.
Expansion
From one platform to a portfolio
With Bol.com as a proven base we're broadening presence. Kaufland is live and in its ramp-up phase, with the assortment expanding step by step. Amazon DE is fully set up and ready to launch.
This reduces dependence on a single platform and creates room for new demand – with the same tight control on performance and data quality.
Looking ahead
Sustainable growth doesn't start with the ad budget
- — Further building organic product value through orders and reviews
- — Scaling the best-performing campaigns into peak season
- — Further expanding Kaufland and Amazon DE
Afdekzeilwinkel.nl proves it: durable marketplace growth starts with a watertight foundation on which ads can then do their work.
Why this is hard
Most brands don't fail on knowledge - but on execution
- —Marketplace growth without a foundation stops the moment you turn ads off
- —Poor product data costs you visibility and conversion
- —Depending on one platform is a risk, not a strategy

What partners say
5-star reviews from brands we work with.
"We've been working together for over 1.5 years. The partnership feels like an extension of our company. They're proactive, think along with us and are focused on results (and they deliver), not on reports. Windrose isn't a standard agency, but a real growth partner. They build their own companies and brands and share that hands-on knowledge with us. That's why they look far beyond 'just traffic or revenue'. They support us in admin, import, customer service, logistics and day-to-day operations. That way multiple areas are tackled at once and different levers are pulled."
Paul
Owner · Afdekzeilwinkel
"Windrose is a really great partner to work with. We have them handle several marketing disciplines, and for each one they have a dedicated specialist. It doesn't feel like an external party, but like an extension of our own team. They take responsibility and actually think along, instead of just ticking off what's asked. In short: very happy with the collaboration. Good communication, the right structure, good results, and they also look at the long term. Definitely a recommendation!"
Ivo
Founder · IVONO
"Working with Windrose has been very positive. Their entrepreneurship, no-nonsense approach and expertise make them a reliable and valuable partner. They think proactively, move fast and know how to tackle complex challenges in a practical way."
Virgil

"We've been working with WindroseHQ for about three years now and in that period we've made huge progress as a company. What I value most: they really think with you. Not from a 'billable hours' mindset, but with good questions and ideas. I've worked with several agencies — WindroseHQ makes the difference."
Remco
Owner · DiamondsByMe
"Six years as our partner and we've made great strides together! Especially this year we've seen huge growth and the partnership is rock solid. On to more wins together!"
Martijn
The Chesterfield Brand
"We've been working with Windrose on social ads for a long time. For the past 1.5 years also across e-commerce, where they act as a strategic partner and think along across the entire business."

Lennart
Owner · Floer
"Worked with multiple agencies and never been as satisfied as with Windrose. Where many agencies limit themselves to media buying, Windrose actually helps you get to the next level. Short lines, fast execution. I'd recommend them to everyone — but I won't, because then they'd have less time for me, haha."
