TxtCart

A bootstrapped Shopify plugin recovers abandoned carts and drives e-commerce sales through conversational SMS marketing. Built as a side project, the platform grew into a full-time SaaS business by solving a persistent pain point for online store owners: re-engaging lost shoppers via personalized text messages at the moment they're most likely to convert. Without any outside funding, the founder scaled the product to $85,000 per month in recurring subscription revenue by staying focused on a single channel and delivering measurable ROI for merchants.
