Pros
Nextiva has the best leadership, culture, compensation, and growth opportunities of any tech company I've worked at. Period. Massive sense of camaraderie and great team atmosphere, fostered by upper management - who lead by example. Executive team is seasoned and fully bought-in to the company and it shows. Added benefit - Nextiva is privately held, which provides room to innovate and think with long-term vision in mind. Company also allows for flexible work schedules and encourages remote work, which is a plus.
Cons
Company has outgrown its current office (plans to move offices in 2020). Can be tough to secure rooms for meetings, etc. But ultimately a good (and fixable) problem to have.
