What people at Sumo Logic say
Reviews originally posted on Glassdoor.
All the potential in the universe to be a differentiating company. The product is great and customers love it. With a few changes, this could be an incredible place to work! It was a wonderful environment even at the beginning of COVID 19 when everyone seemed to pull together but that has slowly changed over time.
Company is well positioned to be very successful in cloud + big data + analytics, strong growing list of customers.
Future has the potential to be bright. Sales team is working hard and the deals are coming in. There are continually new visions for the product that can be fantastic, if they are done right. Could be worse.
Exceptionally talented and dedicated coworkers who love to learn, collaborate, and have fun together.
