Together AI Together AI · Data AI · San Francisco, CA · Sales

This role is responsible for building and managing the model ecosystem for Together AI, focusing on negotiating deals with model builders to bring proprietary and open-source models onto the platform.

  2. Act as the internal champion for our "Model Library," identifying which frontier and specialized models we should bring to Together AI to maintain our competitive edge.

  4. Partner with Finance to construct deal structures that balance aggressive growth with sustainable unit economics, often involving non-standard incentive structures.
  5. Collaborate with Partner Marketing to announce new integrations and create momentum. You will also engage in co-selling efforts, helping our Sales team understand how to leverage specific partner models to win enterprise deals.
