Work and product culture at the RBF startup Velocity?

Considering joining Velocity (HSR, Bangalore) in the capacity of a product manager but I have read a lot of negative reviews about the company on Glassdoor. I also checked their LI and saw that a lot of employees had left Velocity in less than a year. Can someone give me reviews on -

1. Work culture and WLB
2. Product culture and company strategy
3. CEO/CTO review (since I'll be working directly with them)
