Website Design & Development

Trust is the product.
Everything else follows.

We build marketplaces, web stores and one-page shops that handle real money — and we prove it by handing you the URLs. Every site in our portfolio is live, in production, and trading today.

Why Us

Anyone can show you
a mockup

Most web developers show you designs. Pictures of websites that have never taken a payment, never handled a dispute, never had a real customer shouting at them on a Sunday night.

We hand you the URLs instead. Open them. Click through them. They are running right now, with real users and real money moving through them. That is a very different kind of evidence, and it is the only kind we think is worth anything.

The verticals on this site — dental, paragliding, automotive — are not just what we broker. They are what we built. This whole platform is our own product, running our own business. If it works well enough for us to stake our company on it, it will work for yours.

What We Build

Five things,
done properly

01

Multivendor marketplaces

Many sellers, many buyers, and the hard part in the middle: listings, verification, payments, escrow, payouts and disputes. This is the most demanding thing on the list and the one we have running in production.

02

Web stores

Single-vendor shops for a business selling its own catalogue. Fast, cleanly categorised, built to be found in search and to convert once someone lands — without a monthly platform tax on every sale.

One-page shops

One product, one offer, one page, one decision. The whole page exists to move a visitor to a single action. Ideal when you are running paid ads and every click has a cost attached to it.

Brand & service sites

For businesses that sell in person but need to be found and trusted online first. Real content, real structure, working enquiry forms — the sort of site that brings the phone call rather than just sitting there.

Automation & AI

The work behind the website. Automating the steps somebody currently does by hand, connecting the applications you already use so they stop needing a person to copy between them, and wiring a site to its repository and its database so a change goes live by itself instead of waiting on somebody.

It covers the parts that have to be exactly right: a checkout that takes money without losing an order, payment webhooks that confirm a transfer with nobody watching, and live 3D inscriptions and animated objects — so a customer sees their own text on their own plate before they pay for it, rather than after.

And the watching. On our own marketplace, an AI monitor reads buyer–seller conversations and flags the patterns that come before a scam — a request to split the payment, to pay on delivery, or to move the deal onto WhatsApp or Telegram — across several languages, then emails a person to make the call. It flags; a human decides. It has been running on our own money since August.

How We Work

No retainers.
No surprises.

The same honesty rules we apply to our own business apply to yours. We would rather tell you something is a bad idea than take the money and build it anyway.

  1. You tell us what the site has to do

    Not how many pages — what job it has to perform. Take payments? Handle many sellers? Bring in leads from paid ads? The job determines the build, and it is the only sensible place to start.

  2. You get a real scope and a real number

    In writing, before anything begins. If your budget does not match what you have described, we say so at this point rather than halfway through.

  3. We build it where you can watch

    Deployed from day one on a real URL. You see it come together instead of waiting weeks for a reveal, and you can course-correct while changing things is still cheap.

  4. You own it. Completely.

    The code, the domain, the accounts. No monthly fee to us for the privilege of your own website existing, and no lock-in that makes leaving expensive. If you want another developer to take over, they can.

The Stack

Boring technology,
on purpose

There is a fashion in this industry for building simple websites out of enormous frameworks. We do not do that, and it is a deliberate choice you benefit from directly.

What we use

and why it matters to you
  1. Plain HTML, CSS and JavaScript. Loads fast on a phone on mobile data, which is where most of your customers actually are.
  2. Serverless functions. Forms and payments run without a server to maintain, patch or pay for monthly.
  3. Managed database where one is genuinely needed — not by default.
  4. Static hosting on a global CDN. Fast everywhere, and hosting costs are typically negligible.

What you avoid

the usual bill and the usual breakage
  1. No plugin roulette. Nothing breaks overnight because a plugin auto-updated itself.
  2. No monthly platform fee taking a cut of every sale you make.
  3. No framework bloat shipping megabytes of JavaScript to display a page of text.
  4. No lock-in. It is your code. Any competent developer can pick it up.
How a page on a site we build is served A visitor's request goes to static files on a global CDN. From there a serverless function handles form submissions and emails the lead, and a managed database is used only where one is genuinely needed. Visitor on a phone, mobile data Static files, global CDN plain HTML, CSS, JavaScript Serverless function handles the form, emails you the lead Managed database only where one is genuinely needed
There is no server of yours to patch, and nothing that breaks because a plugin updated itself overnight.
Why this matters more than it sounds. Google measures how fast your pages load and uses it to rank you. If you are paying for ads, a slow page burns budget on visitors who leave before it appears. Speed is not a technical vanity metric — it is the cost of every click you buy.
The Work

Live sites,
not screenshots

A marketplace with escrow. A multi-vertical brand platform. A family business with a 56-year trade behind it. All of them running right now.

Tell us what you
need built

Describe the job the site has to do. You get an honest answer within one business day — including "that's not worth building" if that is the truth.

We reply within one business day. Your details go only to Adrenaline Group — never sold, never shared without your say-so.

Common Questions

Before you ask

Can I see something you actually built?

Yes — all of it. Every project in our portfolio is a live site you can open right now. AdrenalineShop is a working multivendor marketplace with escrow. This site is a multi-vertical brand platform. Servis Keno is a client business site. Click any of them and judge for yourself.

Do you use WordPress or a website builder?

No. We build in plain HTML, CSS and JavaScript with a serverless backend. Your site loads fast, costs very little to host, has no plugin bloat and no monthly platform fee, and nothing breaks because a plugin updated itself overnight.

How long does a build take?

It depends entirely on scope, and we would rather tell you honestly than quote a number to win the job. A one-page shop is a different proposition from a multivendor marketplace with escrow and payouts. Tell us what you need and you get a real timeline, in writing, before anything starts.

Do I own the site afterwards?

Completely — the code, the domain and the accounts. There is no monthly fee to us for your own website existing, and no lock-in. If you ever want a different developer to take it over, they can.

Do you work with businesses outside USA and Europe?

Yes. Adrenaline Group LLC is a US-registered company and we work with clients internationally. The work happens online; where you are located does not change what we can build.
