Agentio is a Series B adtech platform that enables marketers to buy creator-led ads at scale, automating sourcing, pricing, contracting, delivery, and measurement. The company has raised $56M at a $340M valuation and is backed by Benchmark, Craft, and AlleyCorp. This is a senior post-sale revenue role focused on account growth and expansion. You will own a book of accounts after the sale closes and be accountable for growing revenue through expansion, cross-platform adoption, deeper relationships, and net dollar retention. Your book will span core accounts (growth-stage brands requiring prioritization and expansion identification) and increasingly key accounts (Fortune 500 and large enterprise organizations requiring navigation of procurement, brand safety review, and complex approval chains). Key responsibilities include: - Own a revenue number with individual quota and accountability for net dollar retention against your book - Identify expansion opportunities and build cases for increased budgets - Drive adoption of new products and platforms as they launch - Multi-thread relationships and engage senior brand leadership to unstick problems - Navigate large organizations through procurement, legal, and brand safety reviews - Convert measurement data (MMM, lift studies, platform attribution) into further investment - Manage a full portfolio and catch account drift early - Help codify and share expansion playbooks across the team You'll operate with significant autonomy in a startup environment without extensive support infrastructure. The role requires 8+ years in advertising, media sales, account management, or client success with demonstrated individual quota ownership and expansion wins. You should have executive presence, comfort with incomplete information and fast decision-making, deep fluency in ad platforms and performance data, and ideally direct experience growing Fortune 500 accounts.
