A business builder is a business model to promote self-sustaining revenue growth of early stage tech startups, involving sales and marketing, strategic and operational support, as well as admin and legal. The model aims to fill a gap in the market between accelerators, business incubators and traditional funding models, such as Venture Capital or Angel Investment. The focus of the business builder is to develop a go-to-market strategy to drive sales and marketing, allowing the startup to generate revenue earlier on, letting the technical founders concentrate on product development.
