Pros
Esper is easily the best company I've ever worked for as a salesperson - the best product in terms of product market fit and customer satisfaction. It fills a need in the market, and feels very mission driven - helping state and local government agencies improve their regulatory and policy processes and connect more seamlessly with the citizens they serve. The team here is also incredible. Everyone works together to get things done, and wins belong to the whole company. Overall just a supportive, positive, forward-thinking place to be. I would highly recommend it to any other sales professional looking to grow or advance their career.
Cons
If you're looking for a massive organization, this wouldn't be the place for you.
