Company balance sheet

Private(unlisted) companies usually don't publish this info so we can't really get our hands on it unless we're an insider. Just afaik, not sure tho

Hard to say as the nos are dynamic and are never shared openly.. it’s basically cash reserves divided by monthly burn rate..

Check for Financial Reports Disclosure in the Investor Relations section. All companies which are not scams would publish it in one way or another.

Screen through financial statements of 3 years. For the actual calculation part, HBR Finance for managers is a good place to start.

These details will not be easily available in public. There is a reason Byjus is ready to pay a penalty for late publishing of annual report.

Aside, on the MCA website you can pay 100₹ and download the balance sheet of a company. But this wont tell you the runway. I have seen some cases where there just a few months of runway left and the employees have no clue. Till last year there was always going to be another fundraise happening. But if the fundraises dont start again companies which had raised 50M$+ are also going to start running out of money soon unless they drastically cut salaries which is usually the biggest expense.
