Best Sales & Prospecting Tools

These tools cover the outbound stack: finding who to contact, pulling verified emails and phone numbers, enriching records, and running multichannel sequences. Any founder or early sales hire doing outbound needs at least a data source and a sequencer. The good ones are separated by data accuracy and deliverability, not feature lists.
