Trained for What’s Next

Working with frontier AI labs, we move at research speed. Our training pipelines adapt as fast as your models evolve — keeping fine-tuning and deployment continuous, not episodic.

Expert Training, Built-In

Tap directly into human expertise across hundreds of domains. Our marketplace connects you to vetted trainers who elevate model performance from day one.

Integrated Quality Tracking

Every label, every iteration, every expert — tracked and verified. Continuous evaluation ensures your data, and your trainers, meet production-grade standards.

Case study

We get results

Cohere matches or outperforms its competitors across agentic enterprise tasks via Invisible evaluations.

Cohere needed to evaluate Command A to see if it delivers the right outcomes in specialized, real-world scenarios. Invisible sourced PhD level experts across a range of specialisms, including STEM, Math, SQL, and subject matter experts in HR, retail and aviation, for blind annotation.

Cohere expanded into 10 languages with Invisible's expert annotators fine-tuning in rare programming languages to tackle specialized use cases resulting in transformative improvements in model performance.

“The deep partnership with Invisible stood out—they felt like part of our team and consistently went beyond what we asked for.”
