Your buyers ask AI. We write the answer.

Brand and content strategy for growing companies whose buyers ask AI about what they sell.

The answer travels. Make it the right one.

How it works

We shape what AI tells your buyers.

Three steps, in order. The first is a document you keep, the second is 90 days of work beside your team, and the third is a choice with no menu.

01 · Week one

Your manifesto

The first thing we write is who you are, whom you serve and how you want to be found. Its test: someone who was never on the call reads it and knows you. Everything after it is built from it.

02 · Days 1 to 90

The sprint

The content strategy and the pages assistants read, written and shipped alongside your team, at one flat price whatever your size. Technical fixes in the first weeks; the content is the work.

03 · Day 90

Two options, no menu

We stay on monthly and keep doing the work, or you keep our engine and run it yourselves. Either way, cancel anytime and keep everything built.

Kept by you: the manifesto, every page, the engine.

What we believe

AI discovery is the new distribution.

Buyers used to find you through search results and referrals. More of them now ask an assistant and take its answer into the room.

01

You're writing for two readers now.

A person judges your tone and trusts your case studies. An agent parses your pages for facts it can repeat accurately to someone who never visits your site. Content built for only one of them fails the other.

02

AEO is the wedge, not the business.

A few technical fixes are a real start and do not take anyone far. What has to change is the content: what a page holds, what belongs on the blog, what the company says in public.

03

Quality is our bet.

Volume and paid placement move AI answers today. We bet that assistants built to serve their users will favor content that helps, and that quality compounds.

Who it's for

Brand and content strategy for companies whose buyers ask AI first.

Your team is already doing the work. We help it grow into the part built for buyers who ask AI first.

  1. 01 Buyers already ask an assistant about what you sell, and you want to be the answer they get.
  2. 02 Someone already works on AI visibility, in house or through your SEO partner, and you're ready to take it past the technical fixes.
  3. 03 You have a growth mandate and a marketing team doing real work, and you want a partner who writes alongside them.

Proof

We publish our numbers, including the ones that came back empty.

Every engagement ends in a receipt: what was asked, what changed, what didn't. Every week ends in a build log. Nothing here is a brochure.

Collimer by Sandcastle Labs

Our engine. It reads what five assistants say about a company, recommends the pages that would change it, and drafts them. We do every sprint with it, and at day 90 you can keep it.
