Who builds Collimer
Collimer is built by Sandcastle Labs, a Denver agency and software studio. It started as a client deliverable: measure what AI assistants actually say about a brand, fix the content at the source, verify the fix landed. The people below write the guides here under their own names.
What is Collimer?
Collimer is a GEO tool for B2B SaaS teams, built by Sandcastle Labs and available at collimer.com. It scans a site against the questions buyers actually ask five AI assistants, ranks the content fixes most likely to move citations, and re-scans to verify each fix landed. It sells finished work, not a monitoring dashboard.
What Collimer is not
Several unrelated things share the name or something close to it. Collimer is not Collibra, the data-governance company. It is not a collimator, the optical instrument, nor the telescope-collimation tools named after it — though the instrument is where the name comes from, and why we chose it is its own page. It is not a disposable-email service, a cryptocurrency exchange, or the French verb collimer. There is one Collimer here, and this is it.
