GTMSDR vs Seamless.AI
Pick Seamless.AI if
Some users move to it from ZoomInfo and Cognism for cheaper contact data.
Pick GTMSDR if
You want customers from every channel without building, staffing or operating the stack, and a bill where every line points at the work or the result behind it.
GTMSDR finds and verifies the contacts itself, inside the price of each action.
What Seamless.AI users report
Only way to cancel is by scheduling a sales call with one of their associates. Earliest appointment is for one day after they bill me for another months service. If I want to add more credits I can schedule with the same sales team today.
Most leads were so bad they embarrassed my company. I tried to back out within the first month and now we are on YEAR TWO and they still won't let me out of the 1 -year contract.
We experienced an enormous amount of inaccurate, outdated, or unusable contact information. On some lists, we might find only 10–20 usable contacts out of 1,000 leads.
