Buyers ask ChatGPT, Claude, Gemini, and Perplexity what you charge — before they open your site. FactMatrix scores those answers against your signed truth pack and delivers a risk PDF plus a canonical /ai-facts page.
No system access required · Public models only · Delivery in 5 business days · Full refund if we miss the window
Visibility tools tell you whether you were mentioned. They do not tell you whether the answer was correct — or costing you deals you will never see in analytics.
A majority of B2B software buyers now begin research in an AI assistant (G2). Wrong price or geo in that first answer ends the conversation silently.
Share-of-voice dashboards optimize for being named. FactMatrix optimizes for being right against the facts you sign — price, plans, region, features you do and do not offer.
A single ChatGPT transcript cannot give a CEO a four-model matrix, a risk register, or a machine-readable page models can cite next week.
B2B SaaS, agencies, and high-ticket services with public pricing and a real sales cycle — founders, CMOs, and growth leads who need an evidence pack, not another dashboard seat.
Four steps. Same prompts. Your ground truth. Timestamped evidence.
From a demo Accuracy Audit. Shows the matrix format you receive — not a live company.

Watch (optional)
Create after first audit buyer asks — not required for day-one sales.
Refund: full refund if we miss the 5-business-day delivery window for the first audit, unless intake was delayed by the client.
Privacy: we only query public AI interfaces with your consented facts. We do not scrape private systems or sell your truth pack.
Confirm three public facts. We run five buyer prompts and email a one-page teaser (Europe/Rome, within one business day). No obligation.
Form posts via FormSubmit to hello@getfactmatrix.com. First use may require a one-time FormSubmit confirmation email.
No. We use public AI interfaces, your public website, and the truth pack you submit.
No vendor can guarantee that. We make correct facts easy to cite, show you what to fix, and give you evidence for internal decisions.
Peec-class tools optimize visibility (were you mentioned?). Evidra sells a similar audit shape. FactMatrix’s wedge is accuracy against your signed truth pack, a CEO-ready evidence PDF, and a hosted facts page — at a mid-market $497 ticket.
Email the same fields to hello@getfactmatrix.com. We treat that as an equivalent free-check request.
No. FactMatrix is research and operations reporting only.
