Main Street is a company that helps people start their own home services businesses with its "business in a box" model, offering training, marketing lead generation, operational assistance, and support for various types of home services such as painting, roofing, and moving. The company uses Bubble's no-code web app platform to build its end-to-end solution. During the COVID-19 pandemic, Main Street had to adapt quickly with limited resources, leveraging Bubble's no-code platform to build a key tool, an Estimate Engine, which helped them validate their product and secure funding. John Jacob, the company's CEO, credits Bubble for allowing him to focus on high-level tasks and emphasizes the importance of offering simple solutions to customers. Main Street aims to expand its services to over 100 business owners and more types of home services.
