What does Assay do?
Assay does the company research you’d normally do by hand before a cold email.
You paste in a list of company websites (or upload a CSV, up to 500) and describe the customer you want in plain words. Assay reads each company’s own site, gives it a fit score from 0 to 100, and fills in what they sell, who they sell to, their size, whether they’re hiring and how they price. You can add up to 6 questions of your own too.
What makes it useful: every answer shows the exact sentence it came from and the page it’s on. A second check confirms the sentence really backs the answer. If it doesn’t, the answer stays on screen and is marked, so nothing is made up and nothing quietly disappears.
You see the cost before a run starts, and you can export to HubSpot, Smartlead or Instantly. You can try one company free at assayai.app/try with no sign-up.
