From €2M to €12.4M revenue. We build this brand ourselves.

"Since early 2026 we've been working with WindroseHQ to accelerate the growth of SIZZ the brand through SEO, SEA and email marketing. Within four months we reached the number 1 position in Google for the search term 'dames longsleeve', above several large fashion retailers. A pleasant and knowledgeable team with a proactive approach and a lot of e-commerce expertise. A valuable partner for our growth!"

"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."

"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!"

"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."

"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."

"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!"

"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."

"Great partner with real added value in the online space!"

"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."
