The question
What good is a beautiful website if it sells nothing?
Out of every 100 websites, about 85 are abandoned. And not every visit is worth the same:
- 85 in 100
websites in the world are inactive.
Netcraft, via Hostinger · March 2026 - 2.2% → 4.9%
People who find you by searching convert more than twice as often as those who arrive from your social media.
Ruler Analytics 2026 · 110M sessions · conversion = qualified lead or sale - 5.8%
Visitors who arrive from an AI assistant convert better than any other channel.

Being talked about is three times more closely linked than backlinks to showing up in Google's AI answers.

Tesserakt builds the other kind: the website people find, believe, choose, and that proves what it sells.

Tesserakt
The website in 4 dimensions.
Ordinary websites have three: they're seen, read and used. Tesserakt adds the fourth: they sell.
Modules
Everything plugs into the same core.
Bookings, the assistant that answers and books for you, or automations all connect to the same website. Tap to plug in.
Real case · Eth Sànglier Ski School · Vielha
They book on the website. It lands on the phone.
The customer picks the lesson, day and level, and pays the deposit in four taps. At that moment, the booking appears in the team's app, without a call or a message.

QuestionsWhat people usually ask
What good is a beautiful website if it doesn't sell?
Not much. Out of every 100 websites, about 85 are abandoned (Netcraft, via Hostinger, 2026). A website that sells does four jobs: Google and AI find it, people believe it, it leads to one action and it measures what it brings. Visitors from search convert at 4.9% and from AI assistants at 5.8%, against 2.2% from organic social media (Ruler Analytics, 2026).
What is a website that sells?
A website that, besides looking good, does four jobs: Google and AI understand it, it shows who you are with real proof, it leads the visitor to one action and it measures how many bookings, calls or messages it brings.
What is neuromarketing applied to a website?
Designing with what is known about how we decide: fewer options, one clear action, social proof where the eye lands first and the price compared with what you already pay. No tricks: no fake urgency, no invented reviews.
How is it different from a website made with AI?
An AI tool gives you a pretty page in minutes. It doesn't give you your story, your details written so AI can cite them, or knowing how many customers it brings. That's what we build.
How much does a website that sells cost?
From €1,470: website chassis €390, visual identity €590 and La Base €490. The message is quoted at €90/h depending on the work, usually between 2 and 10 hours. VAT not included, paid once or in 12 instalments.
What is GEO?
Getting assistants like ChatGPT or Gemini to understand your business so they can name it when someone asks them. We explain it here.
What if I already have a website?
We keep what works and add the missing layers. It's often cheaper.

How many dimensions does your website have?
A short call to see if we're a fit. If your website already does all four, we'll tell you.
