Now in early pilots

The marketing brain for SEO and GEO teams.

Every brief, audit, and report your team produces — client-specific by default. A self-updating brain for each client that plugs into the AI tools you already use. Nothing to configure. Nothing to maintain.

The problem

AI doesn't know your clients.
Keeping it informed is a manual job.

1
Every brief, audit, and report goes through AI tools that don't know who the client is — their brand, voice, audience, or history.
2
Someone on the team keeps brand docs, voice guides, competitor lists and strategy notes updated — by hand.
3
The moment any of that goes stale, the AI output goes off-brand — and someone has to rewrite it.
4
Quality depends on who's doing the work. That knowledge walks out the door when people leave.
How it works

Sits between your data and your AI tools.

One setup. No maintenance. The brain updates itself daily from the work you're already doing.

In your daily work

The brain personalises every piece of work for each client.

Content briefs & articles
In the client's voice, structured the way that's worked for them before.
Technical audits
Focused on this client's site, stack, and what actually matters for their goals.
Competitor & gap analysis
Against the right competitor set — the one this client actually cares about.
GEO & AEO citation work
Grounded in where the client is and isn't cited in AI answers today.
Insights & monthly reports
With full client context — not just data, but what it means for this client.
Outreach drafts
That sound like the client, pitched at the right people in their category.
What changes
Same team. More clients. Better margins.
Day 1
A new team member is effective on a client from day one — not after months on the account.
2–3×
The clients your team can handle without adding headcount.
0
Docs your team keeps up to date by hand. The brain does it.
Hosted in the EU. GDPR-clean from day one.

Running early pilots with a small number of agencies.

Best fit: SEO and GEO teams who already use Claude for daily work.

We set up the brain for a client you pick. Your team uses it for 60 days. If it doesn't earn its place, we walk away.
