Pros
If you choose to work there, your coworkers will be amazing people. Everyone cares about each other and genuinely wants to make the customer experience great.
Cons
It's just not fun anymore. You will never hear the end of a very high minimum number of activities logged in Salesforce every week. Logically generally also adds an uncompetitive amount of margin to hardware and software sales. The PE backing (Tom at The Riverside Company) is, as others have mentioned, very toxic. As a result of this, there's been a large departure of sales reps in the past 12-16 months. The account management team seems to be one big revolving door. Riverside usually keeps companies for five years only, and Logically is in its eighth or ninth year with Riverside, so a sale might be soon.
