About Refinery89

Written by the company

Refinery89 was born in late 2018 out of the frustration of not finding a suitable ad-tech partner that operated with our interests in mind, instead of those of advertisers. We challenge this standard by committing to always putting the publishers first. As publishers ourselves, we have a deep understanding of the challenges faced by publishers in the complex digital ecosystem.

We’ve made it our mission to revolutionize the industry by creating best-in-class ad monetization solutions for digital publishers. Our award-winning technologies give publishers a competitive edge and help to significantly boost the quality, quantity, innovation, and distribution of their ad-inventory. The result? Increased net revenue.

At Refinery, our people are at the heart of our success. Our teams of young, energetic professionals from all over the world are passionate about delivering exceptional service with speed and perfection. We ensure that working with us is always a pleasure!

We are proudly headquartered in Madrid, the sunniest capital in Europe! However, our roots are Dutch. This gives us a competitive advantage by combining some of the smartest and most talented people, with the highly effective, direct but informal Dutch work culture in this beautiful city known for its unique quality of life. We maintain satellite offices in other European capitals for our colleagues on site.

Our offices are a hub of activity and creativity, specifically designed to provide a comfortable and inspiring work environment for our team so that they enjoy being at the office. With drinks, fresh fruit, and a bar for Friday afternoons, or as we Dutch say, de Vrijmibo!

We invite you to meet our team, have a drink with them, talk shop, and discover through our core values and DNA why Refinery is leading the charge in the publisher ad-tech revolution. See you soon!

Their support is very slow.

I have contacted them via email, but they have not responded. Their support is very slow.
They should respond immediately to messages, especially from publishers.
I want to work with your company. I have contacted you several times, including by email, but I haven't gotten a response yet. Please tell me in detail which websites you are working with and what your traffic demand is?

Hi there,

Thank you for reaching out and for your interest in partnering with Refinery89. We appreciate your patience and understand that waiting for a response can be frustrating when you are eager to get started.

To address your concerns directly: we receive a very high volume of applications daily. To ensure we provide the highest level of service and performance to our existing partners, our Publisher Success team manually reviews every site to ensure it aligns with our current technical and traffic requirements.

Regarding your questions on our criteria: While we work with a diverse range of premium websites globally, we prioritize publishers that meet specific brand-safety standards, high-quality content benchmarks, and significant monthly traffic volumes.

As mentioned in our recent email conversation, we proactively reach out to publishers who meet our internal criteria and where we see a clear opportunity to meaningfully increase ad revenue using our technology. If you haven't heard back yet, it may be that your site is still in our review queue or does not currently align with our network's specific requirements.

We value your feedback on our communication speed and will continue to look for ways to improve every publisher's experience, regardless if they are our partners or not.

Best regards,

The Refinery89 Team

Hello Matthias,

Thank you for your review. We will remove your email from our system and have let Louis know.

Please note our intention has always been to help you improve your revenue from ads, and if we have been insistent was only because we really saw a high potential.

If, in the future, you want to explore options please don’t hesitate to reach out to Louis directly.

Best,

Reliable and professional publisher partner

I’ve had a very positive experience with Refinery89. The platform is stable, transparent, and easy to use, with clear reporting and reliable payments.
What I especially appreciate is the overall professionalism and the way everything just works as expected. The dashboard provides all the key insights needed to monitor performance without unnecessary complexity.
Communication and support have been solid, and whenever contact was needed, responses were helpful and clear. Overall, Refinery89 feels like a trustworthy partner that understands publishers and focuses on long-term collaboration.

Amazing company with the best pub manager ever

I am absolutely thrilled to write a review for this phenomenal online marketing company! From day one, their service has been nothing short of exemplary. They are incredibly quick and reliable, creating an environment of trust and professionalism that is hard to come by these days. One of the standout features of their service is the nearly 24/7 availability. No matter when I reach out, they respond promptly, ensuring that all my concerns and queries are addressed swiftly.

A special shoutout to our account manager, Pascalle, who has been an absolute star. Pascalle has taken our accounts to a whole new level of excellence, showing dedication and expertise that surpasses all expectations. Her proactive approach and keen insight into digital marketing have significantly boosted our online presence, driving success that we previously thought unattainable.

Choosing this company has been one of the best decisions we've ever made. I couldn't imagine partnering with anyone else. If you're looking for a reliable, efficient, and effective online marketing service, look no further. This team will not just meet, but exceed your expectations!

Company sent me many unsolicited annoying emails

This company sent me many unsolicited emails regarding "advertising potential" of my blog.

These emails (4 in the span of less than 12 weeks) have never been answered by me but the sales representative Louis Bialek keeps sending similar mails.

That is very annoying and a waste of my time

Great advertising partner

Great partner for publishers big and small. Good support and great people. Along with Refinery89 we have grown from a small publisher to one of the biggest lifestyle publishers in NL. Huge thanks to Robin and Pascalle for their support.

Great commercial and technical follow up by the team.
Doubled the income in Belgium comparing to the big Belgian agencies.

Perfect transition between old partner and Refinery.
