Software Development São Paulo, São Paulo 51–200 employees Founded 2014 Privately Held

Nexaas operates a SaaS platform that unifies inventory, point-of-sale, and fulfillment across physical stores, websites, apps, and marketplaces. The stack is pragmatic (Rails + PostgreSQL + MongoDB on AWS/Heroku) with mobile-first POS capabilities, but pain points reveal operational scaling pressure: acknowledged gaps in DBA and ops infrastructure, high transaction volumes, and churn concerns align with an engineering-heavy hiring focus tilted toward senior hires—suggesting they're solving stability and performance issues rather than feature velocity.
