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.
You: What SaaS categories are growing fastest right now?
