Pros
Co-founders and OG employees are all passionate, friendly and efficient people who really care about the product and its customers.
Lots of room to grow, career-wise.
Cons
They got bought out by a PE and since then things have only gone downhill. Luckily, the dev/engineering teams are still, relatively, not impacted, credit goes to one of the co-founders and management for shielding these teams from corporate take-over.
