Who We Are
Lightning AI is the company reimagining the way AI is built. After creating and releasing PyTorch Lightning in 2019, Lightning AI was launched to reshape the development of artificial intelligence products for commercial and academic use.
Focusing on simplicity, sustainability, modularity, and extensibility, Lightning AI streamlines the lifecycle of machine learning development to expand widespread AI adoption. Its aim is to enable individual and enterprise users to build deployment-ready AI tools without having to hire experts or sink resources into in-house infrastructure.
Lightning AI is a company with offices in New York City, Palo Alto, and London backed by $58.6 million in funding from Coatue, Index Ventures, Bain Capital Ventures, and Firstminute.
Our Values
We are building a company of people that care deeply about the impact of AI on our society. We value:
- Integrity: AI is bound to change how we interact with computers, with each other, and the world—for the better. We are committed to building an inclusive company and developing ethical AI that improves humanity.
- Perseverance: Be bold, take the initiative, and make decisions with confidence. We empower our community, clients, and colleagues to tackle the impossible.
- Curiosity: We are genuinely interested in finding solutions to advance the state of AI research and foster its application in novel products. It's not about whether we can solve the problem, but how.
We also feel that it’s essential to point out the self-evident here – there’s a genuine lack of diversity in our industry, which has to change. One of our goals is to help drive that change. Lightning AI is fully committed to diversity, equity, and inclusion in all of its practices, especially when it comes to growing our team. Our culture promotes inclusion, and we embrace how rewarding it is to work with people from all walks of life.
