The counts are the corrected ones: three businesses active now, twelve adoptions over time, and Where-Woof deployed without a market launch. **Why it is on an engineering CV.** Selling, deploying and still supporting software for other businesses is a different discipline from writing it. Two of the three products carry honest caveats that are stated rather than hidden: the signage platform is being rebuilt, and Where-Woof has not gone to market. **Start here.** [The commercial story](products-business.md) covers what each product is, what state it is in, and what it cost to run.
