Fatal mistake: No transaction revenue capture mechanism: created marketplace value but monetization relied on display ads with no sustainable unit economics
Evaluating only Letgo’s profile at its peak — without knowing the outcome — the model ranked Unit economics as the #1 likely cause. That’s exactly how it died.

Documented cause
Letgo launched in 2015 as a mobile-first classifieds marketplace targeting used consumer goods, backed by $500M from Naspers. The company's photo-based listing format, AI-powered category detection, and polished UX attracted tens of millions of users in a market historically dominated by Craigslist's primitive interface. Growth was rapid: Letgo was the most downloaded shopping app in the US multiple times, and by 2018 it had over 100M listings. Despite this traction, the economics never worked. Classifieds marketplaces are structurally difficult to monetize — sellers list for free, transactions happen offline, and the platform captures no revenue from completed deals. Letgo attempted to build payment and shipping infrastructure to capture transaction value but couldn't change ingrained user behavior. In parallel, OfferUp — a well-capitalized competitor with an identical model — was spending aggressively for the same user base. Rather than either company achieving dominance, both were trapped in expensive mutual attrition. In late 2020, Letgo merged with OfferUp — a transaction that represented no value return to Letgo investors. Post-merger, the combined company's brand and most Letgo features were sunsetted.
