ABOUT INNER AI

We're a startup on a mission of re-imagining how work gets done. We're designing the AI-Native workspace for a new era of human-machine collaboration.

We've taken the first step to solve these issues with our initial product version, which includes features like over 20 step-by-step content templates, tools to enhance readability and improve writing, avatar generation, synthetic image generation, large language model chat in an enterprise-safe manner, and semantic search across company data.

We are backed by top LATAM early-stage investors such as Canary, and our platform is already utilized in daily routines by leading teams across 10+ countries, including Bayer, MercadoLibre, and Embraer.

WHY INNER AI

Our team is intentionally small, which means everyone plays a critical role in shaping our direction. You'll have the autonomy to take ownership, face new challenges, and make your mark. And as Inner AI grows, so will you.
