The Internet of Things is becoming more and more important in many domains. Because in many cases it has the power to create completely new value propositions, new business models have to be designed for new IoT solutions. In the whitepaper presented here we define business models according to Osterwalder and Pigneur (2010) as “the rationale of how an organization creates, delivers and captures value.” While there is extensive literature available related to business model innovation (e.g., Gassmann et al., 2014) and IoT-induced business opportunities (e.g., Fleisch et al., 2014), the IoT Business Model Builder outlined in this whitepaper provides a hands-on, easy-to-use procedure model for developing business models for IoT offerings. It is based on our experience in designing business models for IoT applications in various domains.
