What kinds of companies are in Guezz's customer base?

Guezz is deployed by 1,247 marketing teams across SaaS companies (Notion, Linear, Webflow, Loom, Vercel), DTC e-commerce brands doing $2M–$50M ARR, and performance agencies running paid acquisition for multiple clients. The customer base skews toward growth marketers and CRO managers at venture-backed SaaS and DTC brands.

What results do Guezz customers typically see?

Across 1,200+ customer deployments, Guezz users see an average 38% lift in demo conversion rate within the first 60 days. A Forrester Total Economic Impact study from Q4 2024 found an average customer ROI of 5.4x within the first six months.

How do I find a case study closest to my business?

The customers page groups verified case studies by audience — SaaS, DTC/e-commerce, and Agencies. Each case study row includes the company name, vertical, before/after numbers (demo conversion rate, pipeline added, MQL-to-SQL lift), and a named quote from the marketing leader who led the deployment.

Can I talk to a Guezz customer before booking a demo?

Yes. After booking a 30-minute demo you can request a reference call with a customer in a similar vertical — Guezz's sales team matches you with a reference customer from the same ARR band and use case.

A note from a real customer

"Before Guezz we were optimizing a funnel we couldn't see into. Now we route by intent, not by form fills, and our reps spend Tuesdays closing instead of guessing."
