A founder owns 100% of a startup.
Before Series A, a 15% ESOP pool is created.
Series A investor invests ₹30 crore at a pre-money valuation of ₹120 crore.
Series B investor invests ₹60 crore at a pre-money valuation of ₹300 crore.
Assuming no ESOP top-up after Series A, what is the founder's ownership after Series B?
