About Thorin
Thorin is an applied AI company born out of 8VC’s Build program, focused on redefining how work gets done inside modern organizations. We build proactive, long-horizon AI agents that continuously observe work across Slack, email, meetings, and documents—and take action so nothing falls through the cracks. Unlike traditional AI tools that wait for prompts or rely on structured systems, Thorin creates a real-time digital twin of how a business actually operates, enabling automation, coordination, and insight over months and years. Backed by 8VC and built with product vision from Joe Lonsdale, Thorin is building foundational infrastructure for agentic, AI-powered productivity. With backing and product vision from Joe Lonsdale, Thorin is 8VC’s latest incubation, following the success of Affinity, Addepar, Saronic, and other unicorns. About the Role
We’re hiring a Founding Product Manager to help define Thorin’s product from first principles. This is a core founding role, sitting at the intersection of AI systems, enterprise infrastructure, and real-world business operations. You will own product direction end-to-end: shaping Thorin’s primitives, deciding what the system should understand and automate, and ensuring that powerful agentic capabilities are exposed through products that enterprise leaders can trust, adopt, and scale. This role is not only about backlog management. It’s about deciding what Thorin should become.
