Kaufast team building AI systems and intelligent automation for businesses

We build the AI your business actually needs

You don't need a chatbot that sounds like a robot. You need a system that answers your customers at 2am, books the appointment, and tells you about it in the morning. That's what we build.

Every unanswered message is a customer choosing someone else.

No commitment. No hard sell.

Building since 2004

Three things we do

AI that works while you sleep

We build WhatsApp assistants and AI agents that talk to your customers, answer their questions, qualify leads, and take bookings — all without you lifting a finger. Connected to your real data, not generic templates.

Software that actually ships

Web apps. SaaS platforms. Multilingual systems that work in 12 languages because we've done it. We write code, deploy it, and maintain it. No PowerPoints.

Get found by Google and AI

People still search Google. But now they also ask ChatGPT, Perplexity, and Gemini. We make sure both types of search lead to you.

What Our Clients Say

4.9/5 from 47 reviews

We take on 3–4 projects per month to keep quality high.

We were losing 40% of WhatsApp enquiries because nobody could reply fast enough. Kaufast built us a bot that answers in seconds — bookings went up 35% in the first month.

Frequently Asked Questions

What kind of projects do you build?

We build three things: AI agents (WhatsApp bots, customer assistants), web apps and platforms, and business automation systems. Most clients come to us when they're losing leads to slow responses or wasting hours on repetitive tasks.

How does a WhatsApp bot work for my business?

It answers customer questions instantly — 24/7, in multiple languages. For restaurants it takes reservations, for clinics it confirms appointments, for real estate it qualifies buyers. You get every conversation logged and forwarded to your team when a human is needed.

How much does a typical project cost?

Most projects fall between €2,000 and €5,000. A WhatsApp bot starts around €1,500, a custom web app from €3,000. We scope everything in a free 30-minute call — no surprises, no hidden fees.

How long does it take to launch?

A WhatsApp bot can be live in 2–3 weeks. Web apps typically take 4–8 weeks depending on complexity. We ship fast because we've built the same patterns dozens of times.

Do you also handle SEO and getting found by AI?

Yes — we call it AI Visibility. We make sure Google ranks you and that ChatGPT, Perplexity, and other AI tools recommend you. It's included in our approach because a great product nobody can find is a wasted investment.

What happens after I book a call?

We review your answers before the call so we don't waste your time. During the call we discuss what's possible and what it would cost. Within 48 hours you receive a clear proposal. No obligation, no hard sell — if we're not the right fit, we'll tell you.
