About Us
At Fyxer AI, we're building an AI productivity tool that eliminates the admin burden for client-facing professionals - think real estate agents, consultants, recruiters, people who live in their inboxes. Our product handles the heavy lifting: sorting emails, drafting replies in your tone of voice, taking smart meeting notes, and surfacing next steps. It integrates directly with Gmail, Outlook, and Zoom with no onboarding, no new tabs. Just high-utility software that gets used. Since launching in May 2024, we've gone from $0 to $11M ARR, raised a $10M Series A from top-tier investors (including Marc Benioff and 20VC), and are scaling fast toward $50M.

- You're full-stack enough to jump into backend APIs, write SQL queries, and handle devops basics
- You thrive in high intensity, high ownership environments
- You're excited about AI, not just as a buzzword but for its practical power to transform work
Our Stack:
- Frontend: React, TypeScript
