AI Columns and Jev · Lesson 6
90 seconds
Narration: preview voiceA private equity team finds owner emails only for founder-owned companies. The companies and names are example data.
When you set up Find work email, Find mobile number, Phone type or an HTTP API column, write a yes or no question under Only if Jev says yes. Jev answers it for each row before the column runs. A No skips the row, so no find credits are spent on it. Each check costs 1 credit on Duckrow's Jev, and nothing with your own Jev key.
About five minutes, in your own workspace.
You're done when some rows are Skipped, and only the rest were searched.
Three quick questions. Nothing is saved.
A work email find costs six credits. If a company isn't one you'd buy, a one-credit question first saves the rest.
Set up Find work email, and map the owner, website and company columns. Below, only if Jev says yes takes a question: is this company still owned by its founder? Jev answers it for each row before the find runs.
Add the column and run it. Rows where Jev says no are skipped, and the cell tells you why. The yes rows go on to the find.
On four hundred companies, finds alone could cost up to two thousand four hundred credits. With the check, it's four hundred checks, plus finds on the hundred and fifty yes rows: up to thirteen hundred.
The question works on Find work email, Find mobile number, Phone type and HTTP API columns. Each check is one credit on Duckrow's Jev, and free with your own Jev key.
To recap. Write a yes or no question under only if Jev says yes. Rows Jev says no to are skipped, and cost nothing more. One credit a check, free on your own key. Next, rate a list against your ideal buyer.
