Founding Story

Aryah Oztanir and Ajay Misra started o11 to solve the friction in legacy productivity tools. Believing that products like Microsoft Copilot and Google Gemini underperform, they built o11 to operate directly within Excel, Word, and PowerPoint without requiring file downloads or repetitive editing loops. Aryah took a leave from his university scholarship at age 19 to pursue the vision full-time.
