One team, fully accountable.

We build production AI systems, the kind that real users depend on and that have to keep working under load. Our founder, Tomás Marengo, built and scaled an AI SaaS platform to over 300K in ARR with 200+ paying users as Founding Engineer at Rank Prompt. At MercadoLibre and Mercado Pago he co-led the first internal MCP SDK and shipped Go microservices powering more than 50,000 daily chatbot executions, saving over 500K in two quarters. At Pomelo he deployed AI automation across Finance, People, Legal and Marketing teams.

Nerai Labs brings that same standard to every project. There is no account manager and no relay race of handoffs: you work directly with the people who design, build and ship your software. That is the whole point.

Right now we are helping Zecat, an established promotional-products company, put AI to work across the whole team: replacing manual spreadsheets with automated workflows, building internal assistants, and setting the practices, templates and guardrails so every department can build and automate on its own. That is the model we believe in, not AI in one corner, but a company that compounds it everywhere.

The name comes from 狙い (nerai), Japanese for aim. Tomás also lived that connection directly, selected as one of 100 people from over 10,000 applicants for a program by Japan’s Ministry of Economy, Trade and Industry, and worked a month in Tokyo. Good software is not about doing more, it is about hitting the right target with precision. Every project starts by deciding exactly what that target is.
