Industry Mainstay

Interior Define is a well-established Direct-to-Consumer (DTC) furniture brand known for custom sofas and upholstery. Launched in 2014, it achieved significant scale ($100M+ historical revenue) before facing a liquidity crisis and being acquired by Havenly in 2023. While the project demonstrates high real-world utility and verified traction (national retail footprint, major media coverage), the submission itself is of exceptionally poor quality, containing hyperbolic claims ('most people have used my product') and vague technical details. The score reflects the legitimate scale and utility of the business, penalized significantly for the submission's lack of professional detail and the brand's recent operational challenges.
