"Mollie offers a level of support and an understanding of the European payments and ecommerce ecosystem that high-growth businesses need."
Milan Daniels, Co-founder @ Otrium
Are your partners just vendors, or are they in the trenches with you – helping you move faster, go further, and scale smarter?
Because when you're growing fast, you need more than just a service provider. You need a team that knows your business inside out, faces hurdles with you, and celebrates your wins as their own.
At Mollie, this is the kind of partnership we live for. We don't just process transactions or simplify money management – we invest in our customers' growth.
Of course, it's easy to say that. So, here we show it. Because for Otrium, a leading European marketplace, that’s exactly the type of partnership we have.
From two founders above a coffee shop to a European leader
Otrium started in 2015 with two founders and a bold idea: every piece of clothing deserves to be worn.
"We were just two guys above a coffee shop, surrounded by stacks of unsold sweaters from a business we ran at the time," recalls Milan Daniels, Otrium's co-founder. "We knew fashion had a waste problem – and wanted to fix it."
So, they started to build an online fashion marketplace where brands could sell unsold stock to consumers at discounted prices, keeping clothes in circulation instead of going to landfills or incinerators.
At that time, they needed a payment provider that was easy to work with, adaptable, and capable of growing alongside them. That's where Mollie came in.
"I remember meeting Milan and his co-founder, and they were ambitious, fearless, and determined – just like us." says Adriaan Mol, Mollie's founder. “We weren't just building a business relationship; we were investing in each other's vision."
Otrium's first payment setup was basic – an early-stage WooCommerce integration. But from the very start, Mollie ensured they had everything they needed to convert customers, experiment with new markets, and keep their operations running smoothly.
"Mollie was there when we were doing one or two sales daily," Milan says. "They helped us set up our payment infrastructure quickly to convert more customers while keeping costs in check. And they clearly believed in us even when we were small – and that mattered."

Solving ecommerce payment challenges together
Soon after launch, Otrium's marketplace model gained traction, and they began expanding across Europe. But then, the complexities of cross-border commerce became clear.
"The first market we went into was Belgium, but we didn't fully understand how customers there preferred to pay," Milan explains. "Mollie helped us figure it out, testing different payment methods, running A/B experiments, and getting things right."
Otrium then expanded into Germany, France, and the UK. Each new market came with new challenges: multicurrency transactions (and settlements), cross-border compliance, and mobile-first payment experiences became increasingly critical.
"Unlike other providers that focus purely on automation and self-service, Mollie offers a level of support and an understanding of the European payments and ecommerce ecosystem that high-growth businesses need," explains Milan.
"Localisation is everything in Europe," Adriaan adds. "You can't take a one-size-fits-all approach.
“That's where Mollie does things differently. Unlike global players who see Europe as a local market, we truly localise all across every European country. And that means we can help businesses like Otrium succeed by making sure they don't just 'operate' in a market – but become part of it."

Building for the next stage
By 2020, Otrium had outgrown its ecommerce platform. It needed something more flexible to scale – but switching platforms while running a high-growth business is no small feat. Payments had to keep working seamlessly.
"We couldn't afford even a second of downtime," Milan says. "Mollie understood that – and they worked with us to make sure everything ran smoothly from day one."
The challenge? The existing Mollie integration with commercetools – Otrium's new platform – didn't fully support their mobile app, a key revenue driver. And it needed to work flawlessly from day one.
So, alongside agency Shopmacher, Mollie built a bespoke plugin that easily and seamlessly integrates their solution into any commercetool webshop.
Otrium was the launch partner for the new integration, working closely with Mollie's engineering team to refine and perfect their setup. The result was a setup that wasn't just functional but tailored to the real-world needs of a scaling online business.
"When we told Mollie that the integration needed to be optimised, they didn't push back," Milan says. "Instead, they collaborated with us, built a new connector, and even provided funds to make the transition easier. That's what a real partner does."
“We’re not here to be just another payment provider,” says Adriaan. “We’re building Europe’s go-to financial platform – one that drives growth by putting our customers first. That means listening, adapting, and making sure our tech stays ahead of their needs.”

Optimising costs and unlocking growth
By 2023, Otrium was no longer a scrappy startup – it was a major player. But as it scaled, financial optimisation became critical.
"Even small inefficiencies add up fast," Milan explains. "We needed to make sure our payment costs were lean without hurting conversion."
Mollie ran a deep-dive analysis, testing different payment methods in key markets. The result? Over €100K in annual savings, with no drop in conversion.
"That's the kind of insight you don't get from a typical payment provider," Adriaan adds. "We don't just process transactions – we help our partners make smarter financial decisions."
Otrium also now uses Mollie Capital – a fast, data-driven funding solution designed specifically for growing businesses.
"There's an old Dutch saying about banks," Adriaan says. "'They give you an umbrella when the sun is shining and take it away when it rains.' That's how most traditional lenders operate – but we do things differently."
"Mollie Capital is fast, easy, and accessible – and that’s invaluable when you're scaling fast," Milan says. "Mollie processes our transactions and understands our revenue. That means they can provide funding without all the red tape of filling in forms for days and waiting endlessly for approvals."
