Second company I've used Pendo with, and likely won't be the last.

Adding messaging to your product, without a developer. Monitoring feature usage on the fly - without planning in advance which features you want to track.

My initial review of Pendo was glowing - as was my experience at the time. Since then Support, which was once a huge Pendo plus, has become a disaster. They've moved away from dedicated CSMs - at least for a segment of accounts - and to a centralized support model.. however, it can take a week for me to get an initial response to a ticket. I've had to escalate darn near every one in recent months, and most never get satisfactorily resolved. Feels like major scaling issues going on at Pendo, and a whole lot of untrained people. And yes, this will make me reconsider renewing at the end of the year.
