Our Story

Our firm began with two realizations. Here’s the first:

1. The biggest barriers to the adoption of AI and analytics are not technical—they are legal, ethical, and policy related.

After spending years working in AI startups in Silicon Valley and deploying analytics systems in major financial institutions, healthcare organizations, and elsewhere, we heard the same questions again and again: Is my AI system fair? What does “fair” mean in practice? Can we even use this dataset to train our models? 

The legal, policy, and ethical questions related to AI and analytics were endless and often asked at the end of the model life cycle, jeopardizing time (sometimes years) and funds (sometimes millions of dollars). Both data scientists and lawyers had a hard time communicating with each other and were in need of help.

This brought us to our second realization:

2. The only way to manage the risks of AI and analytics systems is to blend legal, ethical, and policy knowledge with deep technical expertise. 

That’s why we founded Luminos.Law (formerly known as BNH.AI)—the first and only law firm in the world jointly run by lawyers and data scientists. At Luminos.Law, we combine sophisticated legal counsel with tactical advice focused on managing the risks of AI and data. 

That means we don’t just tell our clients what their legal liabilities are—we advise them on the technical controls they should use to measure AI bias and reidentification risk, on the packages they should use to deploy their AI models, and more. Our clients appreciate our technical skill as much as our legal acumen, because they know that in real-world environments, the two simply need to go hand in hand.
