Pros

Remote work Great team No politics

Cons

Leadership is delusional and changes direction and goals faster you can understand them. They want everyone to be working on multiple things in parallel because AI but on the other hand also want everyone to do everything. Their ideology and principals change every month. One month is everyone making decisions on their part, next month is you doing everything. CEO is a big source of confusion and bad vibe.

Execution suffers from constant resets and top-down control

Pros

- 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

Cons

- 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

Was great until it wasn't

Pros

Remote working, with talented people and a great product.

Cons

The leadership team is horrendous and the company's pivot from a DevOps platform to helping militaries across the globe secure their communications while carrying out morally questionable activities is sad. The CEO surrounds himself with people that agree with him, and let's go of anyone that challenges his awful leadership.
