OUR STORY

We’re a team of digital engineers

Rhesis was started by engineers who’ve spent years building and shipping digital products—AI systems included. We’ve seen firsthand how Gen AI applications break in production when they aren’t properly tested. That’s why we built Rhesis: to give teams the tools to validate Gen AI like any other critical software component. No marketing noise, no hand-waving—just a clear focus on making Gen AI reliable, safe, and aligned with real business needs. We collaborate closely with industry partners and the open-source community to make sure our tools stay practical and grounded.

OUR VISION

Testing that fits real-world Gen AI development.

Gen AI is moving fast, but production environments come with real constraints: business logic, compliance rules, customer expectations, and risk. Our vision is simple—make testing fit those realities, not the other way around. We’re building a future where Gen AI teams don’t have to choose between speed and safety. With accessible, open-source QA tooling, developers can validate applications against the things that actually matter: unreliable behavior, harmful outputs, or business misalignment.

Open source innovation.

ou can inspect, adapt, and extend our tools to match your specific needs—whether it’s adding custom validation sets, integrating new LLM judges, or plugging into your existing CI/CD pipeline. Transparency, flexibility, and control stay in the hands of developers, where they belong.

Comprehensive testing

Gen AI apps aren’t used in a vacuum—they operate in regulated industries, customer-facing products, and mission-critical systems. We turn business requirements, compliance needs, and domain knowledge into structured test collections.
