Software for online stores, built by one person and a team of AI.
Stelar Digital makes five apps for stores on Shopify (the platform many online stores run on), a report that shows whether AI assistants like ChatGPT can buy from your store, and paid services for developers. All of it is built, tested and run by one person, Robert, with AI doing the heavy lifting.
Three kinds of software. All of it ours.
