About Fulcrum
Fulcrum works on measuring and optimizing model performance in domains that are hard to specify, such as communication and truthfulness. It is building infrastructure and interfaces for human-AI collaboration in software development, aiming to let a small amount of human intent steer increasingly capable coding agents. Its latest release is Echo, a writing model that adopts the voice of an author the user names.
The company's stated focus is on post-training, elicitation and metric design.
The founding team is described as having published research at NeurIPS and COLM, built widely used open source software, won international olympiad medals, and founded MIT's AI alignment group. Fulcrum is hiring for a member of technical staff and a generalist, with all open roles listed in San Francisco.
Product: Echo, a writing model that imitates the voice of a named author; infrastructure and interfaces for human-AI collaboration in software development.
