Given the importance attributed to the ‘entrepreneur,’ this theory has often been called Schumpeter’s theory of ‘heroic entrepreneurship’ or ‘creative destruction.’...........The important observation now is that this pool of inventions is largely exogenous to existing firms and market structures. ....The essential link between the ‘pool’ of inventions and the ‘market’ is made through the person of the entrepreneur. He is aware of the potential of certain inventions, and as a consequence, becomes prepared to take the risk and the commitment necessary to turn these inventions into innovations. Thus, innovating is more than inventing. As defined previously, it is the (successful) commercial exploitation of inventions. Schumpeter then remarks that such a hazardous activity would not be undertaken by an ordinary capitalist economic agent (such as an existing firm). Only the entrepreneur has the vision, the drive and the commitment to survive the turbulence and the uncertainty involved. If he succeeds, though, the rewards are enormous.

As we can see, "heroic" here means "riskily innovative"
