Business model

Our business model is similar to that of other intermediaries in two-sided markets, including Cars.com, CNET, Etsy, Houzz and others.  This means revenue can be generated on both sides of the market: the consumer and the service provider. 

We are currently generating revenue from the subscription fee our service providers pay to join our network.  Near term revenue opportunities include tuition from online training, and commissions from product sales.  We are now building a product roadmap for SaaS-style/mobile tools that will offer customer management and sales & marketing support to our network.  Future opportunities to generate revenue from our service provider network include financing options and other value-added services.

On the consumer side, we are already generating revenue from product sales.  As we reach scale, there may be advertising-sales opportunities and the ability to sell premium content.  Beyond this, we are collecting large amounts of data about what people do to their homes and what additional cross-selling opportunities may exist.  We believe we will be able to monetize this data. 


Competitive advantage

To understand our competitive advantage, one needs to understand the various steps in the home improvement decision process.  These steps include: need recognition; information search; alternative review; project funding – rebate information; project funding – loans; service provider search; purchase; evaluation; follow-on steps.  Our key competitive advantage is that we are a holistic solution to address all steps of the consumer decision process.
