Was great until it wasn't - Anonymous employee Mattermost Employee Review

Transparency from the first interview Small Business - you do not get lost in the shuffle Everyone is helpful and wants you to succeed Everyone here genuinely cares about their work product Everyone here gives 110% because they care about our customers CEO is hands on - This is a PRO to me! No micro-managing Remote work only Unlimited PTO

You MUST be a self-starter in all sense of the meaning! You must want to learner and grow You have to be customer obsessed This may not be a good fit as a first job for some people

- Talented, hardworking people across the company - Meaningful mission, especially in public sector use cases - Opportunities to learn and grow if you’re willing to operate in ambiguity - Strong camaraderie at the team level

- Frequent strategy resets (cloud → apps → retention → enterprise → public sector) without letting prior efforts mature - Pattern of starting initiatives but not finishing them, leading to partial products and low customer confidence - Leadership often bypasses domain experts, which slows decisions and reduces ownership - Feedback loops feel performative, input is requested but not consistently acted on - Loss of experienced talent without clear reflection or accountability - Benefits and healthcare experience don’t match stated company values - Communication is often top-down rather than collaborative, despite being a communication company - Lack of a clear, durable path to long-term success makes the typical startup tradeoffs harder to justify - CEO must approve all quotes personally, which reflects an overly centralized and controlling decision style
