The fastest path is the WhatsApp button.
Click below and your phone opens WhatsApp with a short pre-filled message ready to send. Four one-line answers: your site URL, what you do, who buys from you, what is bothering you about the site. I reply within hours with a Stripe invoice link for €197. Once paid, the 48-hour audit clock starts.

What to include in your first message
The same four questions whether you reach out by WhatsApp, email, or phone. Total time to answer: under 90 seconds.
- 1Your website URL.
- 2What you do. One to two sentences. Example: “I run a Dutch catering company for corporate events 40–200 people.”
- 3Who buys from you. One sentence. Example: “HR managers booking team lunches.”
- 4What is bothering you about the site. Free-form. Anything you have been wondering about. Examples: “No one is calling.” / “Visitors leave fast.” / “I do not know if it looks credible.” / “I just feel something is off.”
That is the entire intake. No discovery call. No 30-field questionnaire. The pre-filled WhatsApp / email message has these four prompts ready — you just type the answers and hit send.
