Frauds at startups

I was speaking to an ex-colleague and he mentioned how my previous employer, a lending startup, has been intentionally over-reporting disbursal numbers and under-reporting delinquencies in portfolio. They conveniently chuck the NBFC partners who dare to ask questions and instead catch new fish. During my time I saw sales staff committing rampant frauds and making money on the sides from users. The founders conveniently turned a blind eye till there was new business coming in. They've seemingly moved on to the next level now. The founders have top pedigree and already come from well off families. Makes me wonder how many such skeletons are buried across startups and what leads to such behaviour. Especially in the wake of what we saw with GoMechanic, Zilingo etc.
