Summary

Connects Claude to aggregated SaaS market intelligence from TrustMRR, AppSumo, Product Hunt, Indie Hackers, Reddit, and other founder-focused platforms. Exposes two tools: market_query for asking questions about opportunities, revenue benchmarks, and competition, and generate_report for exporting ranked HTML reports with 30+ opportunities and pain points. Useful when researching what to build next or validating ideas against actual revenue data and growth signals without manually scraping a dozen sites. Currently runs on sample data with live pipeline in development. Query it like "show me bootstrapped products under $10K MRR with low competition" or "what are the fastest growing AI categories right now."

FounderSignal MCP

Early access open — Join the waitlist at foundersignal.io

Ask Claude what to build. Get ranked opportunities backed by real market data.

FounderSignal is an MCP server that connects Claude (and any MCP-compatible AI client) to curated market intelligence — revenue figures, growth signals, competition analysis and community pain points aggregated from the platforms founders actually use.

Instead of spending a Saturday copy-pasting data from AppSumo, TrustMRR, Reddit, Google, or Product Hunt into a spreadsheet, you just ask.
