This document compares development services businesses with product businesses. Development services businesses, like software outsourcing consultancies, scale directly with the number of employees and have limited revenue potential. In contrast, product businesses use risk capital to develop products that can be sold to multiple customers, providing leverage and potential for exponential growth. Building an outsourcing business focuses on finding immediate revenue and staying profitable, while building a product business requires perseverance, planning, and financing to develop a minimum viable product and validate the business model before seeking investment from sources like accelerators, angels, or venture capitalists.
