Your website no longer fits your business

Either you don't have a website yet, or you're running an outdated WordPress site that loads slowly and no longer matches your brand. Getting a new one built feels like an unnecessarily complex and expensive process, with agencies taking months and then billing for every small change afterwards. It doesn't have to be that way.

Hidden licenses and vendor lock-in

Traditional agencies build on their own frameworks, premium themes or plugin systems with hidden license fees. Only after delivery do you find out you are legally locked in, paying for usage rights that were never explicitly mentioned in the sales conversation. This is effectively the market standard, but it does not have to be this way.

Dependent on your agency

Every text change, every new page, every small adjustment goes through your agency. You pay again and again for work you should be able to do yourself.

Long timelines, high budgets

Getting a new website built traditionally costs €20,000 to €60,000 and takes three to six months. Meanwhile your competitor just keeps moving.

Most business websites are still built the way they were ten years ago. WordPress with a premium theme, ten plugins stacked on top of each other, and an agency that spends months before you see anything. And once you finally launch, every small change waits on a quote. Adding a new case? Invoice. Updating a price? Invoice. You own the end result, but not really.

We do it differently. We build your business website with modern frameworks that load ten times faster than a standard WordPress site. Astro, React, Next.js and Tailwind as the foundation. A CMS you use to manage content yourself, without the plugin chaos. And because we leverage AI for high-volume work like content structuring, image optimization, multilingual variants, translations and SEO analysis, we deliver much faster than a traditional agency. Not by letting AI make fundamental architecture decisions, but by using AI where it genuinely adds power.

Here is what most agencies will not tell you in the first meeting: they build on their own frameworks, premium themes or closed CMS platforms that you keep paying for afterwards. This is effectively the market standard. We at Managium absolutely do not work this way. Everything we deliver is transferable: complete source code, open technologies and full documentation. Tomorrow you can switch to any other agency or in-house developer without anything breaking. We deliver business websites on average 30 to 50 percent cheaper than a traditional agency, and often three times faster. Not by compromising on quality, but because we work lean with a small, experienced team. No layer of junior consultants, no project managers, no account managers billing hours for progress updates. No handoff delays between departments. Just senior founders and full-stack developers who have themselves built and scaled software companies to 40+ employees. We understand what an SMB CEO cares about because we have been one: speed, transparency, fixed price, and no hidden costs.

Real-world example

Service provider in the creative sector

Context

A Dutch service provider with an outdated WordPress site from 2018, slow load times, no mobile version that actually works, and a backend only the previous developer understood. They wanted a new site but were scared off by quotes of €35,000 to €50,000 from traditional agencies.

Challenge

The site had to go live within six weeks, fully responsive, with a blog section, portfolio, services and a multilingual CMS. Budget was limited but expectations were high. They also wanted to own everything, with no agency dependency, and manage content themselves without having to pay for every half hour of work.

Our approach

We built a custom Astro site with React for interactive parts, Tailwind for styling and a headless CMS for content management. Design and development ran in parallel with targeted AI assistance for content structuring, multilingual variants and SEO optimization. Delivered in five weeks including full code handover.

Results

Site live within 5 weeks, 1 week before deadline
Load time reduced from 4.2 seconds to 0.6 seconds
Total budget ultimately 45 percent lower than the cheapest traditional agency quote
