Your business is good. Your website should show it.

We have built more than 30 websites, and ten of them are shown here. Every client site looks like its business and leads visitors to get in touch. Before you sign anything, you see a free draft of your homepage.

Flaming Weddings

Portfolio with wedding stories, galleries, prices, crew and an enquiry form. The studio adds new stories and photos itself.

What helps visitors

Three typefaces with clear roles: one for the story, one for the tone, one for prices and dates. The site reads like a wedding magazine.

What our clients say. In their own words.

Clients sent these messages to Nik on WhatsApp. Translated from German; the originals are on our German page.

When he presented the first draft, I was thrilled straight away – I immediately recognised myself and my brand in it.

Services

Five services, one person to talk to.

Each service has its own page with examples, the process and answers to common questions. For all five you talk directly to Nik.

Not sure what fits? We work that out in the free process review.

Software and AI

Start where your business loses the most time today.

Sometimes one piece of software fixes a single bottleneck, sometimes an AI agent takes over the groundwork. We connect both with the programs you already use.

Custom software

Software built around the way your business works

Enquiries, quotes and orders live in one place. Office, owner and field staff see the same status without anyone passing lists around.

The first 3 months of maintenance are included, after that it is paid. You own the code and data

Summary

Proposals are written in Word, appointments live in the calendar, follow-ups happen by email. The goal is one workflow that connects all three steps.

Next step: connect the proposal template with the calendar, then attach follow-ups to the same case.

AI agents

AI agents handle the groundwork. You stay in control.

An agent drafts emails, reviews documents and follows up on quotes. Before any step that leaves the house, it asks you.

Replies and reminders wait for you as drafts

Less admin. More time for customers.

We build systems that handle recurring tasks reliably. You can always see what has been completed and where a decision is still needed.

I build the systems myself. When you call, you talk to the person who knows the code.

How we work

You talk to the person who builds it.

Nik leads the first call, designs and builds himself. From the proposal to after launch, he stays your point of contact.

  1. First call

    Your contact: Nik

    You call, send a WhatsApp message or pick a slot, and tell us briefly what you have in mind. A few minutes are often enough, and it costs nothing.

  2. Proposal

    Your contact: Nik

    Within 24 hours, you have in writing what you get. If anything changes later, we discuss it before we build on.

  3. Draft

    Your contact: Nik

    Before we build, you see the draft on your own phone or computer. Bring along what you like and tell us what we should change.

  4. Build

    Your contact: Nik

    Nik builds it himself and also answers your calls and messages. You never have to explain your project twice.

  5. Launch

    Your contact: Nik

    It only goes live once you are happy. We set everything up and show you and your team how it works.

  6. After launch

    Your contact: Nik

    If something should be added or is not working, you reach Nik on the same number as the first time, by phone or WhatsApp.

  7. What we build

    belongs to you.

    Code, data, domain and logins are registered in your name. You can take the project with you at any time, including to another provider.

Talk to Nik about your project.

On WhatsApp, by phone or with a booked slot. The call is free, and afterwards you decide in your own time.

Data protection

We host in the EU. Access rights and the handling of personal data are agreed for your project. We clarify any specific requirements of legal and accounting practices before implementation.

Guarantee

Our satisfaction guarantee covers design and development: until you approve, we revise within the agreed scope at no extra cost. The terms are set out in your proposal.

FAQ

What to know before the first call

Six questions that come up almost every time, answered up front.

The cost depends on the scope and the integrations you need. After the free process review, you receive a proposal within 24 hours with the scope, timeline, effort estimate and billing model. If the scope changes, we discuss the impact before implementation.

Next step

What is costing your business time or customers today?

Send a short WhatsApp message, call or pick a slot. The first call is free. Afterwards you know what is worth doing for your business, and you decide in your own time.

You talk directly to Nik. He leads the call and works on your project himself, without a detour through a sales team.
