Website, marketing, AI and custom software, all from one partner

Websites that bring in clients. And the marketing to match.

We build a complete preview of your new website before you spend a cent. No commitment, no catch. Once you have seen it, you decide whether to go ahead. From there we grow with you: SEO, ads, AI, automation and custom software.

One partner, three layers. Start wherever you are.

A beautiful website is worthless if nobody finds it, and traffic is worthless if you cannot follow it up. That is why we work in three layers that build on each other. Start with the foundation and grow when you are ready.

Example of a modern business website on laptop and phone 01

Website, webshop and brand

AI assistant and automations handling leads and processes 03

AI, automation and custom software

Scale

Work you do by hand today, running on its own. From an AI agent that follows up your leads to software that does exactly what your business needs.

  • An AI agent that qualifies leads and books appointments
  • Automated quotes, invoices and follow ups
  • Integrations between systems that currently do not talk to each other
  • Custom portals, tools and apps
Your free preview

A working prototype or demo built around your situation, within 72 hours.

How you pay

Based on a strategy call and a phased proposal: discover, build, manage.

Just want a website? That works too. You choose which layers to switch on, and when.

Everything between ‘wouldn’t it be nice if’ and ‘it just works’. We build it.

OneStone is not a web design shop that dabbles in marketing. We build whatever your business needs to grow, from the first page to the systems behind it. A few examples:

A lead agent that never sleeps

An AI assistant on your website and WhatsApp that answers questions, qualifies leads and books appointments straight into your calendar. Even at three in the morning.

Ten hours a week back

Quotes, invoices, CRM updates and follow ups that run themselves. You only see what actually needs your attention.

A portal for your clients

Bookings, files, order status or documents in one place that belongs to you. Connected to the tools you already use.

Custom work always starts with a call and a short discovery phase, so you know exactly what you are getting before we build anything.

This is what your free preview looks like

No quote, no sales pitch. We build it, you take a look.

OneStone was born out of frustration. Good businesses stuck with a website that does not fit them, one agency for SEO, another for ads, and nobody looking at the whole picture. Everyone builds a piece, nobody builds the whole.

We are the one stone everything rests on: website, visibility, ads, automation and custom software, from one partner under one roof. And because we know what we build, we would rather show it than promise it. Your preview is free, so you decide with zero risk.

Good to know.

Is the preview really completely free?

Yes. We build a first version of your website without you paying anything, signing anything or committing to anything. Not for you? We simply stop and it costs you nothing. We only agree on a price once you are happy.

What is the catch?

There is none. We take the risk because we know most businesses want to go ahead once they have seen the preview. If you do not, we have spent a few hours getting to know you. We are fine with that.

What does a website from OneStone cost?

It depends on the scope. Because you see the preview first, you know exactly what you are saying yes to. We charge a one off fee for the build and a fixed monthly fee for hosting and maintenance.

Do I have to take all three layers?

No. You can start with just the website and switch on Growth or Scale later. Many clients start small and expand once the first results come in.

Do I also get a free preview for apps and AI?

Yes, in a lighter form. For a website we build a first version. For Growth we do a free audit, and for AI and custom work we show you a prototype or demo built around your situation within 72 hours. The full build only starts once you approve a proposal.

How is a custom application priced?

In phases: a short discovery phase where we define exactly what is needed, then the build at a fixed price per phase, and finally monthly management and development. You always know where you stand.

How does the ad budget work?

You pay your ad budget directly to Google and Meta. We charge a fixed monthly management fee and never take a percentage of your media spend.

Can I edit the website myself?

Text and images are easy to change yourself. Bigger changes fall under maintenance, and we handle those for you.
