Executive Assistant + Office Manager

About Agentio

Agentio enables marketers to buy creator led ads as easily and scalably as Meta or Google ads-automating sourcing, pricing, contracting, delivery, and measurement with AI-so work that took months now happens in minutes.

We're on a mission to transform a $800B digital ad ecosystem by shifting digital ad spend into the hands of creators. That means better outcomes for marketers and enabling creators to live off their work-finally being paid in proportion to the value they create. That shift is accelerating:
Unilever's CEO has said the company will move roughly half of its ad budget into social and creators-Unilever is among the world's largest advertisers, spending around $9-10B annually. As these dollars move, they need performance-grade pipes;
Agentio is how those dollars flow to creators with the speed, control, and measurement marketers expect. We enable brands like Uber, Door Dash, and Bombas to run creator campaigns with the same rigor, control, and accountability as their core performance channels.

Agentio has raised $56M to date at a $340M valuation, including a recent Series B led by Forerunner, which followed our Series A within a calendar year. Our investors also include Benchmark, Craft, and Alley Corp. Agentio has been named to Forbes' Next Billion Dollar Startups, 2025, and our platform is already used and loved by the world's leading marketers and creators.

We are just getting started!

About the Role
