For construction, installation & trades

The system that sells while you're on the job.

One temple of ten building blocks — brand, website, SEO and an AI sales agent (Meindert) — installed in the right sequence. Not four separate vendors. One system, one point of contact, one outcome: more qualified inquiries.

We install digital growth infrastructure for capital-intensive trade businesses: contractors, installers, landscapers, painters and property-maintenance firms doing €300K–€2M in revenue. At the core is Meindert, an AI sales agent that follows up on your inquiries 24/7, qualifies them and books appointments — while you're on the job. Around it we build brand, website and SEO as one system. One build, one monthly growth engine, and a guarantee: more qualified inquiries within 4 months or we continue at no cost.

Where trade businesses lose revenue

In two places at once. Most agencies fix one. Never both, never as one system.

You're invisible

Your site is there, but it doesn't rank. Nobody finds you, so everything comes from referrals — and that's slowing down.

You're too slow

The inquiry lands at 7pm, no one picks up, and the client calls the next name. Every missed after-hours inquiry is a job for your competitor.

Ten building blocks, one temple

Each block in the right sequence, so every one compounds the next: SEO feeds the website, the website feeds Meindert, Meindert feeds your calendar. A temple with a crooked pillar collapses — separate services do exactly that.

At the core of every build: Meindert

Meindert is an AI sales agent, trained on AIDA and pain-pleasure psychology. Not a chatbot that says 'hi, how can I help?'. A system that qualifies and books appointments — within 90 seconds, 24/7, while you're on the job.

  • Every inquiry answered within 90 seconds, day and night
  • Qualifies the lead and books straight into your calendar
  • Trained on your services, prices and service area
  • Runs on n8n + Claude, connected to your CRM and WhatsApp

Frequently asked questions

Capital-intensive trade businesses — contractors, installers, landscapers, painters, maintenance firms — doing €300K–€2M in revenue, where the owner is on the job during the day and misses leads after hours.

Because separate vendors don't talk to each other. Your site builder, your SEO person and your chatbot deliver three invoices and zero coherence. We build the ten blocks in the right sequence, so SEO feeds the website, the website feeds Meindert, and Meindert feeds your calendar.

€8,000 to €15,000, based on your average invoice value. At an average job of €5,000 you're around €8,000; at €20,000 around €10,000; at €50,000+ between €12,000 and €15,000. One missed job pays for the whole build. We work that out together in the intro call.

Normally €3,000. While we have spots, we do it for free. You get a concrete roadmap showing where you're leaving revenue on the table — even if you don't continue with us.
