About the role

Key responsibilities & impact

You will own how Siena grows. New customers, existing customers, and everything between them.
Demand creation, product launches, brand, content, expansion, retention as a marketing motion. The full surface area of how the world finds Siena and how Siena keeps the customers it earns.
You work directly with both founders. You build the function. You build the team.
New customer acquisition. Demand creation across every channel that works. Brand, content, social, events, paid, partnerships. The pipeline that fuels Series A and beyond.
Existing customer growth. Expansion, adoption, retention as a marketing problem. Customer marketing, co-marketing, references, community.
Product launches end to end. Every release becomes a market moment. Positioning, messaging, distribution, the works.
Category leadership. Siena is creating the category of CX operating system for brands. You own how that category gets defined and adopted.
Brand and momentum. The campaigns, content, and presence that make Siena the first name in CX AI.
The growth system. You build the AI agents and workflows that let one person move like ten. You orchestrate. Your taste is the final filter.

Requirements

What you’ll need

AI-native. You build agents. You build systems. You've replaced workflows with AI before you joined us, and you'll do it again here.
A builder. You've shipped something from zero. A function, a brand, a company, a community. You operate without a brief.
A storyteller. You write. You shape narrative. You take a complex AI product and make it feel inevitable.
Creative and analytical in equal measure. You have taste, and you have a pipeline dashboard open. You move between a campaign concept and a CAC payback model without flinching.
Scrappy. You ship in hours. You experiment constantly. You kill what doesn't work.
Fluent in selling AI. You understand what makes AI products different to market. You've done it, or you've studied it closely enough to tell us exactly how you'd do it here.
