ServiceGraph

Founders looked at the startup data landscape and saw exactly what you'd expect—a mess of outdated listicles, broken links, and Twitter threads from 2021. So they built ServiceGraph: a live database of where to actually launch, who to actually email, and who to actually hire. No scraping, no stale Notion docs. Real directories with real DR scores, agencies with real ratings and locations, newsletters with verified subscriber counts.

They've got 1,100+ product directories indexed with submission policies and traffic data, 1,800+ business directories tagged by industry, 50k+ newsletters sorted by topic and posting cadence, and 110k+ agencies with services, size, location, and ratings. Coming soon: subreddit communities and influencer data by niche. Everything filterable, sortable, exportable—in other words, everything those static Twitter lists aren't.

The pitch is simple: stop guessing. Want to know which directories actually drive traffic? Filter by DR and visitors. Need newsletter sponsors that match your ICP? Sort by subscriber count and topic. Shortlist agencies in Austin that do devRel? Sort by location and rating. Their API works with Claude Code, Cursor, Codex, Copilot, and 14+ other agents—so your AI can pull verified contacts without leaving its sandbox.

Pricing is pay-as-you-go: 2,000 credits free on signup, then 1,000 for $10 or 10,000 for $80. That's roughly a dime per row. For founders who got tired of googling "best SaaS directories" and getting results from 2022 with half the links dead—they just made the obvious tool.
