Valid Spark
Market research and SaaS idea validation for founders.
Overview
Valid Spark helps founders validate SaaS ideas by turning real-world conversations into a structured market research report. You enter a topic (and optional context), choose data sources, and the app collects evidence, extracts recurring pain points, and synthesizes a report with frequency and TAM-style estimates. Today the product focuses on Reddit + Quora analysis, with an extensible model for additional platforms.
