Pros

CEO has a vision about the company future. He is doing a good job there and the company has been growing fast past a few years. There are a lot good and very profession people: marketing, sales, customer success and engineering. There is a lot of learning opportunities.

Cons

New CTO came last year and made a lot of questionable decisions. As result very professional engineers (knowledge holders) left the company. Looks like CTO has no idea how to develop Software SaS products. Also he doesn't listen experts who have spent many years in the industry. The company will lose engineering power very soon that was built last 6-7 years.

Pros

Not a single pro, this company is awful

Cons

- Leadership promotes their boys club buddies that severely lack leadership skills - The product sucks. It's nowhere near industry standard - The culture is HORRIBLE. Very much sink or swim, no support, zero engagement with other employees unless you suck up to them or are in the office - Mid Market "RVP" leaders are some of the worst Ive ever seen. If you dont go to them to appease their ego for every little thing, they will "manage" you out - SKO was the worst broke company efforts Ive ever seen. Shouldnt have had one, this company is embarrassing. The public speakers and corny jokes were the most cringe thing Ive ever witnessed, Ive never felt more demotivated in my life - Boys club culture to the fullest, if you dont stroke everyones ego, you're out Stay far away from this company. Go to a real CX/UC company. FIve9 is begging for acquisition and no one will take them. The system is old and ugly. Run from this org. Don't bother.
