Questions

FAQ

Is my data uploaded anywhere?

No. Your browser reads the file and builds the new one on your computer. Nothing is sent to us or anyone else. Switch your wifi off once the page has loaded and it still works.

Which CRMs does it work with?

Anything that exports a CSV or Excel file. It recognises HubSpot, Salesforce, Apollo and Sales Navigator column names automatically. Anything else, you match the columns yourself in a couple of clicks.

Can it read Excel files?

Yes. .xlsx and .xls, plus CSV, TSV and TXT.

Does it guarantee a match rate?

No, and be wary of anything that does. Matching is down to the platform. This removes every reason your file would fail or match badly on our side.

Can it turn a contact list into a company list?

Yes. Choose "Contacts to companies". It pulls the domain from each work email, drops the Gmails and Hotmails, and builds a LinkedIn company list.

Does it hash my data?

No need. LinkedIn, Meta and Google all hash your list in your browser when you upload it.

List sorted. Now the hard bit.

Uploading is easy. Turning a list into meetings is where most campaigns fall over: the wrong job titles layered on, boring ads, budget spread too thin.

That's the bit we do for niche B2B firms.
