E-commerce and physical product case studies
These are businesses that sell physical products: own-store e-commerce, D2C brands, marketplace sellers and handmade shops. Small Start records revenue, margins, ad costs and sale prices where disclosed, with sources.
In physical products the gap between revenue and take-home is wide. Where sources allow, cases break revenue down to profit — like a D2C at ¥12M revenue and ¥2M profit per month.
