83/1334 → 19/976; -4.28 percentage points of formation share.
Straight-up storefront and marketplace bets like Krave Mart and Proglix have largely given way to companies that plug into other people's stores rather than building their own, a shift visible in Numeral handling tax compliance for 3,000+ businesses, Movley doing quality control for 800+ Shopify and Amazon brands, and Converge tracking marketing attribution for online stores that already exist. That split matters because the formation's overall growth has cooled to 0.31x while the closely related "Ecommerce Tools" category is growing at 1.83x, suggesting capital and founder attention have moved from selling things online to instrumenting the sale itself. Companies like Corgi Labs, built for fraud and dispute detection, and OneText, rebuilding checkout around SMS, are further evidence that the interesting problems left in this space are now infrastructural rather than retail-facing. The rise of generative AI tools like Booth AI for product imagery and Apply Design for virtual staging also signals that content production, once a marketing afterthought, has become its own product line, a change plausibly tied to image-generation models becoming commercially usable around 2022. As AI systems increasingly do the discovering and persuading on a shopper's behalf, tracking which algorithm, asset, or consent actually drove a purchase becomes a real unresolved question, one that touches Converge's attribution work directly and will only get harder as more of the funnel is automated rather than browsed.
AI-generated discovery and persuasion may blur which system influenced a purchase and which customer data, creative asset, or consent allowed that intervention.
