Ended up switching to default due to lead routing issues with Chilipiper. Great and easy integrations with our existing tech stack. Pretty easy to use.
It is not just the calendar booking, you can setup workflows based off a bunch of different triggers and use that to make enrichments, edits, create new objects.
Very easy to get in and started. workflows are pretty straight foward.
Default is a revenue-grade workflow engine that lets you see your revenue machine, understand how it all connects, and scale without breaking anything.
