The AI Tools Directory

How to use this AI tools directory
Three steps from a vague need to an exportable shortlist.
Pick a sector or search a problem
Start from the category grid below or type a free-text query: "vector database", "AI sales coach", "coding agent". Our search resolves to underlying sector tags so you do not have to know the exact taxonomy.
Filter by stage, geography, or signals
Narrow the list by funding stage (pre-seed → growth), HQ region, founding year, and our proprietary agent-readiness score. Every filter is URL-shareable, so you can bookmark or send a filtered view to a colleague.
Open the profile, then export
Each profile shows funding rounds, investors, founders, and a direct link to the company site. Pro tier and above can export filtered slices to CSV or pull the same data through our REST + MCP API.

vs. other AI tool directories
Coverage, filterability, and price compared side by side.
| Directory | Limitation | StartupHub.ai Directory |
|---|---|---|
| Crunchbase | Paywall on filters, $49+/mo, no AI-specific taxonomy | Free filtering, AI-native categories, MCP and REST API on every plan |
| Product Hunt | Daily-launch feed, no funding data, no filtering by sector | 19,100+ startups indexed with funding, investors, sectors, all filterable |
| G2 / Capterra | Review aggregator skewed to enterprise SaaS, sparse on early-stage AI | Coverage starts at pre-seed; agent-readiness score replaces noisy review counts |
| Theresanaiforthat.com | Tool index only, no company / funding / investor data | Tool + company + funding + investors in one record, single API surface |
| Manual Google search | Hours of tab-juggling, missing funding context, no exportable list | One filtered URL, exportable CSV, structured fields ready for downstream tools |
