Mat Hofma, the creator of Mini Materials, started the company to sell miniature masonry and woodworking supplies like cinder blocks, bricks, and lumber. The idea took off after Mat posted his development story on Reddit, leading to a surprising demand for the miniature cinder blocks. Since then, Mini Materials has expanded its product range to include different styles of mini masonry and kits for building models. Initially, Mat Hofma was a graphic designer with aspirations to start an e-commerce shop. He taught himself 3D design and created molds for the miniature cinder blocks, which became the foundation of Mini Materials. The company officially launched in March 2015 from Portland, Oregon, and has since grown to generate $20,000 in monthly revenue with a team of two founders and two employees.

Adam Elliot founded Dick At Your Door, an e-commerce shop specializing in prank gifts like solid chocolate penises. The idea originated from a silicone penis mold discovered during a prank with friends, leading to the creation of a humorous gag gift business. Initially started as a joke, the venture quickly gained traction, evolving into a successful e-commerce enterprise.
