Client Growth Manager

Agentio • New York, NY

2d • $150,000 - $200,000 • Onsite

About The Position

Agentio enables marketers to buy creator-led ads as easily and scalably as Meta or Google ads, automating sourcing, pricing, contracting, delivery, and measurement. Work that took months now happens in minutes.
We're on a mission to transform an $800B digital ad ecosystem by shifting ad spend into the hands of creators. That means better outcomes for marketers and creators finally being paid in proportion to the value they create. The shift is accelerating. Unilever's CEO has said the company will move roughly half its ad budget into social and creators, and Unilever spends around $9-10B annually. As those dollars move, they need performance-grade pipes. Agentio is how they flow to creators with the speed, control, and measurement marketers expect. Brands like Uber, DoorDash, and Bombas run creator campaigns on Agentio with the same rigor and accountability as their core performance channels.
Agentio has raised $56M at a $340M valuation, including a Series B led by Forerunner that followed our Series A within a calendar year. Backed by Benchmark, Craft, and AlleyCorp. Named to Forbes' Next Billion-Dollar Startups (2025) and Inc.'s Best Places to Work (2026).
This is a post-sale revenue role. Customer Growth owns a book of 25 to 30 growth-stage accounts after the sale closes and is accountable for growing it through expansion, cross-platform adoption, deeper and more senior relationships, and net dollar retention. You carry a quota. Your job is to wake up every morning figuring out how to make your number bigger.
A note on environment. We're a startup, so the people who thrive here build their own operating system, prioritize without being told, test a narrative, and share what worked. The people who struggle wait for permission.

Requirements

• 5 to 7+ years in client-facing roles in advertising or media with demonstrated individual ownership of revenue outcomes.
• Experience carrying a quota or an equivalent number, and knowledge of performance against it.
• Proven track record of real expansion wins personally sourced and closed.
• Experience saving at-risk accounts.
• Experience winning budget before performance data existed to justify it.
• Senior client presence: ability to build relationships with directors and VPs of marketing, hold strategic conversations with decision-makers, and earn respect.
• Autonomy in execution: ability to run your book day to day without hand-holding, spot opportunities, and bring leadership recommendations.
• Deep fluency in ad platforms and performance data.
• Comfort operating without a safety net and confidence to identify opportunities and act quickly.
• Genuine use of AI in workflow.
• Self-starter who narrows the aperture to what moves the business.
• Understanding that Agentio builds in person and is in office 5 days a week in New York.

Responsibilities

• Identify expansion opportunities, build the case for increased budgets, drive adoption of new products and platforms as we launch them, and defend our share against incumbent agencies and channels competing for the same dollars.
• Build relationships beyond your day-to-day contact, get to senior marketers and decision-makers, and know when to pull in leadership for top-down pressure.
• Navigate the landscape of client measurement (MMM, lift studies, platform attribution) and sequence commercial asks around what a client's measurement will support.
• Know where the growth is in your book, keep every account healthy, catch drift before the client tells you, and reactivate churned accounts.
