TL;DR

  • Most companies feeling stuck digitally have a frontend problem, not a backend problem

  • A full replatforming is rarely necessary

  • A modern frontend presentation layer can sit on top of what you already have, giving marketing independence and IT control without rebuilding from scratch

I've spent most of my career in frontend engineering, working in traditional systems where one platform was trying to do everything. I know firsthand what it feels like when every small change becomes a bigger project than it should be. 

These days, as Operations Manager, Nordics, at Vaimo, I work at the level where strategy meets delivery. That means I understand both sides: what teams deal with day to day, and what clients get frustrated by.

The symptom most companies recognize 

When organizations come to us feeling stuck, they rarely arrive with a clear diagnosis. What they feel is slowness. Things take too long. Marketing wants to launch a campaign, and IT says it will take weeks. Someone needs to react to a competitor, and the system can't keep up. Every small visual change requires a developer, even for things that shouldn't.

There's also a deeper tension that builds over time. Marketing is asking, "How hard can it be?" while IT is doing their best, but working in a system where one small change can ripple into a dozen others. Both sides end up frustrated. And that frustration becomes a real, ongoing cost in itself.

What most of these companies have in common is not a broken backend. They have a broken frontend.

Why replatforming is often the wrong answer 

The natural assumption when your digital experience feels slow or broken is that you need to replace the whole thing. But before jumping to that conclusion, ask yourself, "What's actually causing the problem?"

Most companies already have a functioning foundation, with an established commerce platform and integrations to PIM, CRM, etc., with years of business logic built over time. The problem is that your existing data is locked into a specific way of being displayed, which limits how quickly you can innovate on the frontend.

There's no point building a new house just because you want to renovate the kitchen. A full replatforming is often rebuilding something that already works because the part that doesn't work is somewhere else entirely.

Nearly every modern platform can serve as a solid foundation. You just need to separate the two layers and give each one the right tools.

What a frontend presentation layer actually is

A frontend presentation layer is everything a user sees and interacts with across your digital touchpoints, whether that's on desktop, mobile, or any other channel. It connects the complex data and logic sitting in your backend to the user, translating it into a clear, interactive experience.

In traditional setups, the frontend and backend are tightly coupled. When you change something on the surface, you often end up touching systems deep underneath. A frontend presentation layer changes that by decoupling the two. Your backend systems keep working, while your frontend gains the freedom to evolve independently, faster, and with far less risk.

The concept goes by many names, including buzzwords like headless frontend, composable frontend, and DX layer. The underlying idea is the same. Separate the frontend from the backend, make things modular, and stop asking one platform to do it all.

Where the real cost shows up 

When a frontend is fragmented or slow to change, the cost shows up in more places than one.

There's the direct time cost: slow implementation cycles, high estimates for small changes, and developers pulled into work that shouldn't require a developer at all.

There's the opportunity cost: campaigns that launch late or not at all, and competitive moves you can't respond to in time.

And then there's a cost that's easy to overlook: the people. Onboarding takes longer in legacy systems. Developers working in outdated environments are less satisfied. Marketing teams that feel constantly blocked become disengaged. Those aren't line items in a budget, but they're very real over time.

Gartner estimates that technical debt will consume more than 40% of IT budgets. That number tends to resonate with IT leaders. The frontend is where technical debt is most visible to your customers or end users. While debt exists throughout the stack, the presentation layer is the most practical place to start "paying it back" to see an immediate ROI.

What changes when you get this right 

We've worked with customers to rebuild their frontend presentation layer on top of their existing backend, without replatforming. The impact has been clear across traffic, revenue, and user experience. But the day-to-day change for the teams involved is just as important.

Giving the business control over their digital content removes the middleman.

It frees up the technical partner to move away from small, daily updates and focus on building the advanced features that keep the brand ahead of the competition. Modern headless content management systems are built specifically for what marketing teams actually need. They can work in one place and push content out to multiple channels at once. That shift, from being dependent on development capacity to being able to move independently, changes how a team can operate entirely.

IT, meanwhile, keeps control of security, governance, and backend stability. The two teams stop fighting over the same system and start working in parallel.

The bar has moved 

The competitive pressure to modernize has never been higher. Today, almost anyone can put together something that looks polished in a matter of hours. What used to take weeks or months to build is increasingly a starting point, not a finish line. Competing without a modern tech stack has never been harder. And that raises the stakes for every organization still waiting to act.

You don't have to feel held back 

The message I want to leave people with is this: you don't have to feel held back by your current setup. Getting something modern doesn't mean undertaking a full replatforming. It doesn't have to be a year-long project or a huge budget.

You can take your organization into the future through incremental steps instead of a full replatforming. That's what a modern frontend presentation layer makes possible, and it's what we'll be showing in practice at our upcoming Masterclass.
