Built for operators
We built What-Stack because we needed it ourselves. Growth teams deserve better than manual tech lookups and stale data.
Our mission
Make web intelligence immediately usable for action.
If a user can't turn an insight into a list, a feed, or an export, it doesn't ship. That's our bar.
We're not positioning as "another tech lookup." We're positioning as a web signal warehouse that outputs:
- Segments — saved lead definitions
- Feeds — what changed this month
- Exports — CSV/Excel/Parquet
- API + MCP — programmable access
What we're not
Not a heavy UI analytics suite
We're built for export, not dashboards.
Not a contact database
We deliver signals. You own your contacts.
Not a crawler that hits every page
Smart, targeted detection. Not brute force.
