For curious entrepreneurs who are interested in SaaS startups. The all-around nature of the entrepreneur is mainly because there is nobody else to do the job. Either the job has not yet been filled, contracted out, or there is not enough capital to cover a full-time employee for the role.
To keep up with the requirements of the job, the entrepreneur has to know something of everything. This can be accomplished by being involved with the right people who’ve had enough practice and excellent work experience, by working with the right people such as professionals/consultants, or even by outsourcing some business functions to a third-party provider.
