About Fixpoint
Summary
Fixpoint builds a marketplace that sources, vets, and deploys human annotators and AI trainers onto data labeling and model evaluation projects. It serves AI teams that previously staffed these roles through slow, manual recruiting. The platform automates annotator matching, qualification checks, and payroll, replacing a fragmented staffing process with a managed network of domain experts.
Business model
A fee on each completed annotation or evaluation project staffed through the platform.
Go-to-market
AI development teams and enterprises needing labeled data or human-in-the-loop oversight are the buyers, accessed through a marketplace model where Fixpoint handles expert sourcing and deployment end to end.

Uber for AI trainers and human-in-the-loop supervisors
Fixpoint is Uber for human data annotation. We’re building the network of experts and the platform to automate sourcing, vetting, and deploying them on AI training projects. It used to be a manual process to staff people on AI training data or eval projects - but Fixpoint leverages AI to staff people and create data better, cheaper, and faster. This includes a network of pre-vetted experts, AI-automated vetting, and annotator management + payroll.
