A visitor lands.
Guezz's lightweight script (12.4 KB gzipped) attaches a session to every anonymous pageview across your marketing site, docs, and pricing pages — no cookie banners, no PII capture.

02
Reverse-IP resolves the company.
We enrich the visitor's network against 41M company records — pulled from first-party crawl, vendor partnerships, and verified firmographic feeds. Median resolve time: 74 ms.

03
GPT-4o scores fit and intent.
Our model — first to ship on GPT-4o in October 2024 — reads on-site behavior (pages, dwell, repeat visits, referrer) plus firmographics and assigns a fit score from 0–100 with a written reason. Scored 4.8/5 in G2's Winter 2025 report.

High-score visits route to your AEs.
Visits above your threshold push to HubSpot, Salesforce, Slack, Marketo, Segment, Pipedrive, or a webhook — with the company name, score, page viewed, and reason code already attached.

"We watched marketing teams keep buying point tools — chat here, lead scoring there, reverse-IP somewhere else — and stitching it all together with a Zapier apology. So we built the layer we wished we had at Drift."
Guezz started in Austin in 2021 as an internal tool that Mara and Dev used to route Drift's inbound demo requests. When they left to start Guezz, they brought two convictions with them: that visitor intelligence should be one product, not four, and that it should pay for itself in 60 days. The Forrester TEI study from Q4 2024 put the average customer ROI at 5.4× within six months — a number that tracks with the $11.4M in pipeline customers have generated from the free GTM Playbook included with every plan.
