Nexus IA: The São Paulo startup redefining supply chains for 10,000+ small retailers

Walk down Rua Augusta on any weekday morning, and you'll see the problem Nexus IA set out to solve: thousands of small shop owners juggling handwritten ledgers, spreadsheets, and guesswork as they manage inventory. In June 2026, the Vila Mariana-based startup announced it had crossed 10,000 active users across São Paulo's retail sector—a milestone that signals how artificial intelligence is quietly reshaping the commercial backbone of Latin America's largest city.

Founded in 2023 by a team of former engineers from the Fundação Getulio Vargas' business school, Nexus IA built an AI system that learns from historical sales data, weather patterns, foot traffic, and local events to predict what products a small retailer should stock and when. For a merchant running a shop in the Pinheiros neighbourhood or along Avenida Paulista, the platform costs between R$299 and R$599 monthly—less than hiring an additional employee, but delivering insights that previously required expensive consulting.

The impact is measurable. According to internal data shared with The Daily São Paulo, retailers using Nexus IA report a 23% reduction in excess inventory within three months and a 17% increase in stock turnover. For neighbourhood pharmacies, bakeries, and convenience stores operating on razor-thin margins, that difference is the gap between sustainability and closure.

What sets Nexus IA apart isn't the technology—neural networks for demand forecasting exist globally—but its obsessive focus on the Brazilian market's specific friction points. The system accounts for the seasonal quirks of São Paulo's economy: the spending surge before Carnival, the school holidays in July, the concentrated purchasing before the FGTS withdrawals hit accounts. It integrates with local payment systems and works offline, a crucial feature in a city where internet reliability remains inconsistent in peripheral zones.

Competition is intensifying. Global platforms like Shopify and local competitors are moving into inventory automation. Yet Nexus IA's founders argue their advantage lies in community: they run weekly workshops in coworking spaces in Brooklin and Consolação, training users directly. By June, they'd trained over 2,000 retailers face-to-face.

The startup is now raising its Series A round to expand beyond São Paulo into Rio de Janeiro and Belo Horizonte. For a city grappling with economic volatility and complex supply chains, Nexus IA represents something increasingly rare: technology designed for local realities, not imported wholesale from Silicon Valley.
