Pros
Is it the perfect company? No. I do not want to downplay the negative reviews on this site because everyone has different experiences that should be respected.
That said, PitchBook is the best company that I have worked for by far. The company innovates, allows you to work autonomously (at least in Customer Success), and gives you access to speak directly to upper management. The fact that managers and directors listen to your problems and take steps to address them is huge. The fact that the HR department is even responding to negative reviews is a testament of how much this company cares about its employees. I feel like my contributions to the company are noticed and my hard work is rewarded. You are a name and not a number to the CEO, COO, and upper management here (if you want to be). That's not something you see at most companies.
Also work-life balance is amazing. You put in your time and you can have a life when you go home. Try working for an I-bank and do that. Not gonna happen. Nobody calling you over the weekend or micromanaging you is a breath of fresh air in financial services.
Cons
Diversity at the firm needs a lot of improvement; as with most tech companies. Employee referrals are great but the employees making those referrals need some diversity in their personal lives as well.
Compensation could be better. Corporate culture is superb. Compensation could be better.
Loosen up PTO and WFH policies.
