Yes, all the startups which raised funding from the sharks might not get the investment after the show.

The startup has to show all its revenue and balance sheets for approval after the show.

Due Diligence or audit will be done by the CA's of respective Judges ( Aman, Anupam) with the startup.

Eventually, Sharks won't make an investment in the startup.

Even Ashneer Grover told that out of 20 startups in season 1, he invested successfully in 15 startups. Rest failed in due diligence.

Aman Gupta also stated that even he also noticed that 4 to 5 startups failed in the audit.

So, startups have to be very specific with their numbers or revenue, or balance sheet in the Shark Tank India show.
