River AI
API for fine-tuning open-weight models
At River AI, our mission is to create personal AI owned and shaped by each individual. To achieve this, we are building the full stack required for people and organizations to create AI models of their own—from training infrastructure and open-weight model post-training to personal hardware and next-generation interfaces.
Who we are
We are scientists, engineers, and builders from the industry’s leading technology companies and AI labs. Our team has experience scaling consumer products to hundreds of millions of users and building the infrastructure behind frontier AI systems.
About the Role
We are seeking experienced Founding Account Executives to drive the growth and adoption of River API.
River API makes it easy for companies and individuals to post-train open-weight models using their own data, creating models that are more effective, economical, and specialized for their use cases. Your goal will be to turn this technical capability into a rapidly growing business, with a particular focus on creating and closing enterprise sales campaigns.
You help create critical parts of River API’s go-to-market motion, from identifying high-value customer segments and closing early strategic accounts to developing partnerships and building repeatable systems for scaling adoption. This is a highly entrepreneurial, cross-functional role for a small group who can operate across sales, partnerships, product, and technical customer engagement.

River AI helps developers and enterprises train, fine-tune, and own custom open-weight AI models using its River API, which focuses on open-weight models rather than a single lab-owned general model. The API supports LoRA fine-tuning and reinforcement learning on frontier open weights, featuring fast weight transfers, sampling-training consistency, elastic compute, and token-based billing that avoids idle GPU charges. It differentiates itself by enabling true ownership and control of models, offering a full-stack solution for training, fine-tuning, and deploying custom models without relying on a centralized general model. Its goal is to empower individuals and organizations to own, customize, and run their own AI systems with close-to-the-user control.
