What they say about us

As scientists and AI researchers, we spend significant time on model evaluation. The Patronus team is full of experts in this space, and brings a novel research-first approach to the problem. We're thrilled to see the increased investment in this area.

Jonathan Frankle
Chief AI Scientist at Databricks

"Evaluating LLMs is multifaceted and complex. LLM developers and users alike will benefit from the unbiased, independent perspective Patronus provides."

Max Bartolo
Command Modeling Lead at Cohere

"Testing LLMs is in its infancy. The best methods today rely on outdated academic benchmarks and noisy human evaluations -- equivalent to sticking your finger in water to get its temperature. Patronus is leading with an innovating approach."

Andriy Mulyar
Co-founder and CTO of Nomic AI

"Engineers spend a ton of time manually creating tests and grading outputs. Patronus assists with all of this and identifies exactly where LLMs break in real world scenarios."

Linus Lee
AI Whisperer

Patronus AI doesn’t just help you build trust in your generative AI products, they make sure your own users trust your products too. They always go one step further to make sure you succeed with your AI use case in production.

Azadeh Moghtaderi
Vice President of Data

The Patronus team is taking a holistic and most innovative approach to finding vulnerabilities in LLM systems. Every company that wants to build LLM-based products will need to solve for it and the Patronus team is the most thoughtful group tackling this problem.

Barkha Saxena
CDO at Chime

One of the standout features of Patronus is its customizability. I can bring my own evaluations or set up my own Custom Evaluator in 30 seconds, and then do everything else from there within the platform.

Chen Peng
VP, Head of Data & ML of Faire

Patronus AI is at the forefront of multilingual AI evaluation. DefineX is excited to be using Patronus’ proprietary technology to safeguard generative AI risks in the Turkey & Middle East region and beyond.

Emre Hayretci
Co-founder and Managing Director at DefineX

Patronus and their straightforward API makes it really easy to reliably evaluate issues with LLMs and mitigate problems like content toxicity, PII leakage, and more. We're excited to partner with Patronus to combine their evaluation capabilities with Radiant's production reliability platform to help customers build great GenAI products.

Nitish Kulkarni
Co-founder and CEO of Radiant AI

I love that Patronus supports both offline and online workflows. It’s a game changer when an engineering team has to do no extra work in making their offline evaluation setup work in real-time settings. This is because their API is really easy to use, and is framework-agnostic and platform-agnostic.

Lior Solomon
VP of Data at Drata

In our mission to bring the AI stack close to enterprise data and offering best in class tools to train and deploy AI solutions, we are thrilled to partner with Patronus AI. Our combined platform will help in training, finetuning, rigorously testing, and monitoring LLM systems in a scalable way.

Mouli Narayanan
Founder and CEO of Zeblok

AI won’t take your job but it will change your job description. Safety in the workplace and security in the workspace is the only way to be AI-ready. That’s only possible with Patronus.

Gabriel Paunescu
Co-founder and CEO of Naologic

One of the neat things about the Patronus experience is the part that comes after catching LLM mistakes - insights with natural language explanations, failure mode identification, and semantic clustering.
