“one user told us like oh my girlfriend would love that she's selling on depop and after multiple users asking us in support talking at the user interview at mcdonald we realized that oh that's a niche that we should kind of focus on”
E-Commerce Niche Wasn't Planned — It Emerged From Support Tickets and McDonald's Interviews
PhotoRoom's defining market positioning — the best photo editor for entrepreneurs selling on Depop, Poshmark, and Shopify — was not a strategic decision made in advance. It emerged from repeated signals in customer support tickets and McDonald's user interviews. The team noticed the pattern, validated it, then deliberately doubled down. Niche clarity often comes after launch, not before.
