THE SHIFT

Search didn't die. It moved into the chat.

Your customers used to Google you, click a blue link, and land on your site. Now they ask an assistant, and it acts for them, often without you. The brands that become an app inside the LLM, not just a mention in its answers, will own the next decade of demand. Everyone else is a footnote in someone else's reply.

The new front door
Buyers open a chat before they open a browser. That first conversation is where the brand relationship now begins.
Talked about, not transacting
The model can describe you, but it can't book, quote, or sell for you. There's no live app behind your name. The buyer is ready to act. Nothing happens.
Zero-click, zero-signal
When the model answers, you get no visit, no lead, no idea what they asked. The intent is happening without you.
HOW IT WORKS

Your brand, native inside the LLM

We build and run the app and MCP server. You show up where the decisions are made.

01
We build your brand app + MCP server
Sponja turns your catalog, pricing, docs, and booking flows into a live app and Model Context Protocol server. It's the interface LLMs use to act on your behalf.
02
It goes live in ChatGPT & Claude
Your brand becomes something users can open, ask, and transact with, right inside the conversation. Like Booking.com's app, but end-to-end yours.
03
You capture leads + real intent
Every conversation becomes a qualified lead and a first-party signal: what they asked, what they wanted, where they dropped. Piped straight to your CRM.
WHAT IT DRIVES

One presence. Every stage of the funnel.

Lead generation
Turn AI conversations into pipeline. Every buyer who asks about you becomes a captured, qualified lead. Top of funnel, on autopilot.
Control the answer
Today the model describes you from scraped, secondhand data. With Sponja, the answer comes from your live app: your prices, your policies, your words, in the chat.
Customer retention
Existing customers get instant, on-brand answers, book time with your team, and claim renewal offers without leaving the chat they already live in.
Know what they want
For the first time, see exactly what your market asks for, in their own words. Every question, objection, and buying signal. Yours, not a platform's.

The window to own your category inside the LLM is open right now. It won't stay open.
