Head of Growth

MEET SIENA Siena is the Agent of Record for consumer brands. One agent that owns the entire customer journey, running on a shared intelligence layer no point tool can replicate. Consumer brands run ten or more disconnected tools to manage their customers. 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. One agent across every surface, with shared memory, shared context, and shared tools. 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 We are a small, fully distributed, global team. We have built leverage into how we work, which is what lets a team this size move at the speed we do. We hire athletes. Everyone here owns real outcomes, defaults to writing over meetings, communicates with directness, and acts 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 Siena is the CX operating system for brands. The product is shipping faster than the market can absorb it. We have the customers, the proof, the momentum. What we need is someone who turns all of that into compounding growth. 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. WHAT YOU'LL OWN - 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. The 130 brands we already serve become our biggest growth lever. - 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. WHAT WE'RE LOOKING FOR - 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. WHY SIENA? - Real ownership. You will own problems, not tasks, with the autonomy to solve them your way and the trust to do it without a manager in your inbox. - Work that ships and matters. What you build reaches real consumer brands fast. - A category we are creating. The Agent of Record is new ground, with unsolved problems and cutting-edge models, not a crowded field to compete in. - A team that respects your judgment. Globally distributed, async-first, low bureaucracy. We hire adults and treat you like one. - Gr
