I am also founder of a Shopify web design/development agency called WITTY, wittycreative.com (founded in 2009). We help people every day try and increase their sales by increasing their conversion rates. Many of them complain about their abandoned cart rate and I thought there had to be a solution to this issue that greatly decreased the abandoned cart rate for all stores.
After a second, it came to me to build an app that allows consumers to save all of their carts from around the internet into one cart and allow them to checkout on all of them at the same time, and also build a merchant version of the app that allows merchants to send messages to consumers who have their products in their 'CartSaver' cart, even when they don't have their email or phone number.
There's a lot more to it but that's the general idea. We think it has a lot of potential to become a daily used app for all consumers and merchants 🤞
