TestFi - On-demand user testing platform with screen recordings and AI analysis

Published Mar 16, 2026

🔴 Problem Identified

Founders and product developers struggle to understand why real users bounce from their apps, despite positive feedback from friends and early testers. Traditional user testing is expensive, slow, or requires complex SDKs. Founders are left guessing about usability issues that prevent user adoption.

💡 Proposed Solution

A platform where founders post their app links, real testers matching target demographics apply and get selected, then record themselves using the product while thinking aloud. AI analyzes these recordings to identify specific pain points, confusion areas, and drop-off moments, providing actionable insights without requiring code integration.
