Have worked with Marcus for about a year, and it has been a very pleasant experience. Marcus always delivers on time and replies immediately. I have worked with different larger teams before, where I got a new account manager constantly, and with that, had to spend a lot of time troubleshooting. With Marcus it's nice to know that won't happen, and it saves me a lot of time. My best recommendations ⭐️⭐️⭐️⭐️⭐️
Ditte from Mondo Kaos
I had the pleasure to work with Mads and Marcus on setting up the FB ads strategy for our online store. They did such a great job with setting up our Top & Bottom funnel. Before we implemented their strategy we were just losing money on our ads, they turned that around and now we´re really seeing the results!! I would highly recommend these guys, they´re one of the least marketing agencies where you´ll get high quality value for a reasonable price.
Nas from Simply Her
I am extremely impressed with the results. The company's communication and dedication to our campaign has been top-notch. Every week, they provide us with a video update explaining the progress and strategies being implemented to improve our results. I highly recommend Complex Solutions for anyone looking to set up and manage their Facebook-Ads.
Maurice from Hello Floor
We are incredibly grateful to Mads and Marcus from Complex Solutions for their exceptional work. They are true professionals who go above and beyond to deliver a top-notch solution. If you're looking for a dedicated and service-oriented team to bring your vision to life, we wholeheartedly recommend Mads and Marcus from Complex Solutions. They've proven themselves as experts in their field and incredible partners for any e-commerce project.
Henriette from Forest Tea
Marcus and Mads have been a pleasure to work with over the last 3 months. We got our small webshop optimized and structured our Facebook and Instagram ads - and got a much better return on investment! The thorough Monday updates helped to give us a thorough insight into things and created a sense of security in the process.
Andreas from Eclipsis
We have been working with Marcus for 6 months now and are really impressed with the results he creates and the way he manages to challenge our business strategically. Marcus has been a very important resource in our expansion into other countries in Europe, where he has taken responsibility for opening and growing the different markets. Despite the fact that we work with complex products with many restrictions, we have experienced throughout the collaboration that Marcus adapts and finds the right solutions that benefit our business. We are especially pleased with the execution power we experience. High recommendation from here!
Mads from Matetea
Can only recommend Marcus from Complex Solution, super service minded, problem solver, creative and fast. Marcus is always available and always ready to try out new ideas. He provides weekly updates, constantly keeps an eye on conversions, ROAS, ad spend etc. He also focuses on increasing revenue/conversions and sparring on problem solving. We at Åberg Copenhagen look forward to a long and good collaboration, which we are very enthusiastic about so far.
Ne from Åberg Copenhagen
My business benefits from having Marcus on the sidelines. Marcus is a breath of fresh air with a lot of ideas. Without a doubt one of the sharpest in the business.
Lukas
Huge recommendation from here! Marcus has been managing our Facebook Ads for about 3 months now and has created impressive results all the way through.We are running with a ROAS 13 on average and have made an additional turnover of 500.000kr. in the short time we have worked with him.Marcus is self-thinking and proactive and works insanely hard to create the best possible results for his clients!
Anton from Owayy
I have been on a mastermind with Marcus and his team. It was a great investment, due to the fact that they are really competent and professional about what they are doing. 5 starts and a warm recommendation from here. Asbjørn / Raymondo
Asbjørn from Raymondo
At Complex Solutions, you will be greeted by a professional and skilled team that is always available when you need them. The ads are taken care of on a daily basis in order to create the best results. In addition, we have received a weekly update where they review the ads, ad spend and action steps for the coming week. We have optimized a lot of functions on our webshop in order to create a better shopping experience for our customers, and we have received sparring all the way. I would give Complex Solutions my highest recommendation and look forward to continuing our fantastic collaboration in the future.
Daniel from By Sarah Lykke
I can highly recommend both Marcus and Mads. We at Curved.dk have been using them for over a year now. We are growing every single month, they are always ready to help and do a fantastic job. They are 100% honest and easy to talk to, so I can vouch for them at any time. Thank you Marcus and Mads for the time so far, I look forward to many more months with you.

Our holistic approach to scaling E-commerce & Info-Product businesses

Having mediocre ads, landing pages, and creative content is no longer enough. We ensure a consistent thread throughout your marketing mix, where we don’t just look at one channel in isolation.

We take a holistic approach to your business and ensure that you are present on the channels where your customers are. We handle all paid advertising channels. 

With a monthly spend on the best-performing marketing channels in the millions, you get the best team of marketing specialists who understand what it takes to take your business to the next level.

Your ads cannot compensate for a low-converting landing page, which many businesses forget. You can have the best ads, but it’s pointless if your shop doesn’t convert. 

We help fill the gaps in your customer journey so that we can also convert the visitors we send through Paid Advertising.

Paid Advertising

Facebook & Instagram Ads, Google Ads, Snapchat Ads, Pinterest Ads, Tik Tok Ads, and more

Email Marketing Automation

A/B Testing

Landing pages, offers, messages, and more

Conversion Rate Optimization

Content Creation

Feels like your own in-house team, without the expenses or management needed

“We practice what we preach.” We run our own E-commerce brand with revenue in the millions, so we know what it’s like to have skin in the game and spend hundreds of thousands on Facebook Ads out of our own pocket. I assume you’re on our website because you’ve seen one of our own Facebook Ads. 

That’s how we get all of our clients. Why should you hire us if we can’t even advertise for our own agency?

We collaborate with Danish and international companies and currently advertise in over 8 countries. We don’t just set up your ads. We are your right-hand and sparring partner regarding your online marketing strategy.

We have spent over $3.500.000 for our Danish & international clients on the best-performing marketing channels.

We have cut out all unnecessary tasks and slow processes so that we can use all our time to create hardcore conversions that can be felt on your bottom line. We only report and measure the KPIs that matter to your business.

Do as our Danish & international partners and book a free 30-minute meeting with Mads where you can find out if we can help you grow your business. At the end of the call you will have a clear understanding of what it takes to take your business to the next level.
