Sandcastle Labs

Sandcastle Labs is an AI visibility agency. Buyers now ask ChatGPT, Claude, Gemini, Perplexity and Grok which companies to trust before they ever visit a website. We help growing companies show up in those answers, and describe them accurately when they do.

Every engagement starts with an AI visibility audit. Using Collimer, our proprietary scanning engine, we query five major assistants with real buyer questions and measure how often your site is cited and what each assistant says about you. You get a scored baseline and a ranked list of fixes, ordered by impact and effort.

Then we do the work alongside your team:

- Brand manifesto: a clear, written definition of who you are, who you serve and how you want to be found, completed in week one.
- 90-day content sprint: the pages and content that assistants actually read and cite, written in your voice and shipped with your marketing team.
- Verification: after changes go live, we re-scan to confirm the score moved, so results are measured rather than assumed.

At day 90, you choose a monthly retainer or keep every deliverable and run it in-house.

Our bet is on quality. Assistants are built to serve their users, so they favor content that genuinely helps. We don't chase volume or technical tricks. We publish before and after numbers for our work, including a developer-tools company whose AI citation rate rose from 1.25% to 5.8%.

We work best with companies whose buyers already ask AI about what they sell, and whose marketing teams are ready to move beyond technical SEO fixes.
