What you get.
- 50 technology lookups a month, plus 50 email verifications.
- The technology your best customers share, which is usually your cleanest ICP filter.

- A browser extension that reads a stack during research without spending a lookup.
How to set it up.
Create the free account, then run a lookup on your best five customers and note what they share.
Turn that shared technology into your qualification filter, since it is the pattern your product already fits.
Set website alerts on your most important accounts, using the 5 the free account allows.
Install the extension so a stack check happens while you research, without spending a lookup.
Track lookups through the month, because 50 goes quickly once a team is using it.
