Unfortunately we can't support 150 prompts free of charge because of the infra cost etc.

If you're keen to collaborate and explore, please reach out to hello@geovector.ai, and we can work something out. :-)

Our approach is research-based, using position-adjusted scoring grounded in published GEO literature. The Y Combinator report is one example of the analysis we run.

We ran 150 prompts across ChatGPT and Gemini, tracking 21 brands. Three things that surprised us:

1. Techstars outranks YC on ChatGPT despite YC's far stronger Google presence 2. YC's own site accounts for just 8 of 940 AI source references 3. The single most-cited source driving competitor visibility is a blog post on pitchwise.se — not any accelerator's own website

Full report at the link, no signup. GeoVector runs this analysis for any brand or vertical.
