Valid Spark
Market research and SaaS idea validation for founders.
§ 01·The brief
Fig. A — Problem · Position · Constraint
What it solves.
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.
- Replaces guesswork with evidence from real user discussions
- Surfaces repeatable pain points, not isolated anecdotes
- Quantifies signals (frequency scoring) to prioritize what matters
- Converts messy raw posts into actionable problem statements + sources
- Adds competitive context to guide positioning
