Meet Siena. Siena is the Agent of Record for consumer brands, owning the entire customer journey on a shared intelligence layer that no point tool can replicate. Consumer brands typically run ten or more disconnected tools to manage their customers, but we collapse that stack into a single agent. It started with support, the hardest surface a brand has, and it expands from there: Shopping Agent, Social Agent, Siena working alongside a brand's own operators. Hundreds of brands already run real customer volume on Siena in production. This is built, working, and growing, and we are racing to build what comes next.
The team is a small, fully distributed, global group that has built leverage into how we work, allowing us to move at speed. We hire athletes who own real outcomes, default to writing over meetings, communicate with directness, and act the moment they see something worth acting on. Low ego, high standards, fast clock. If you want to own real problems rather than close tickets, keep reading.
The Role involves owning the commercial relationship for Siena's highest-value brands, including renewals, expansion, executive trust, and knowing your accounts better than anyone. You will hold your accounts to specific, measurable commercial outcomes: net dollar retention, expansion, and the strength of the executive relationship. You will lead commercial reviews, executive account mapping, and account planning, and run in-person workshops, account visits, and QBRs with your accounts. Expect moderate travel.
