An OPC has certain limitations. The person starting the business is its only director and shareholder. There can be a maximum of 15 directors in OPC. There is also a nominee director, but this person has no power whatsoever for raising equity funds or offer employee stock options. The nominee exists only to take over in case of the death or incapacitation of the director. The nominee is chosen by the director and can be anyone, such as your spouse, parents or siblings. The nominee will need to provide identity proof during registration.
