Title: Founding Product Manager
Location: San Francisco
Company: Thorin
Stage: Seed | Incubated at 8VC
About Thorin
Thorin is an AI startup born out of 8VC’s "Build", focused on solving AI-human coordination by analyzing organizational email to map and automate recurring business workflows. Thorin enables leaders to run their businesses like a program — with real-time visibility, predictive control, and automated execution across the enterprise
With backing and product vision from Joe Lonsdale, Thorin is 8VC’s latest incubation, following the success of Affinity, Addepar, 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.
What You’ll Do
Own Thorin’s product vision and roadmap across visibility, process modeling, guardrails, and agentic execution
Define the core abstractions of the Thorin platform — what a “process,” “policy,” “metric,” and “agent” mean in a living enterprise system
Partner deeply with AI Engineers to shape agent behavior, evaluation frameworks, reliability thresholds, and iteration loops
Work hand-in-hand with Infrastructure leadership to ensure product decisions meet enterprise-grade security, compliance, and scalability requirements
Collaborate with Product Engineers to design and ship intuitive user experiences on top of complex AI systems
Lead customer discovery with design partners and early enterprise adopters, translating messy operational reality into clear product direction
What You Bring
5+ years of experience building and owning complex software products, ideally in enterprise, platform, or infrastructure-adjacent domains
Proven ability to operate as a founding or early-stage PM, defining product direction in the absence of precedent
Strong technical fluency — you can reason about AI systems, distributed infrastructure, and product tradeoffs without needing abstraction layers.
CS degree strongly preferred
Experience working closely with engineers on systems where reliability, trust, and correctness matter
Exceptional product judgment — you can turn ambiguous, high-stakes problems into crisp product decisions
Comfort with uncomfortable ambiguity — you enjoy operating without playbooks
Clear, structured project management and communication skills — you can align engineers, customers, and leadership around a shared product vision
Bonus:
Experience with AI-native, agentic, or automation-heavy products
Familiarity with enterprise workflows
Background in process modeling, operational analytics, or enterprise systems of record
Prior experience selling or deploying products into large enterprises
About the Team
You’ll be one of the earliest non-engineering hires and a core part of the founding team
You’ll work directly with senior AI, infrastructure, and product engineers building Thorin’s technical core
You’ll collaborate closely with design partners and enterprise leaders shaping the product in production
You’ll work directly with Joe Lonsdale, who remains deeply involved in product vision, strategy, and hiring
Expect extreme ownership, rapid iteration, and the opportunity to define a new category of AI-driven operational software
