Who We Are

Lightning AI is the company behind Py Torch Lightning. Founded in 2019, we build an end-to-end platform for developing, training, and deploying AI systems—designed to take ideas from research to production with less friction.

Through our merger with Voltage Park, a neocloud and AI Factory, Lightning AI combines developer-first software with cost-efficient, large-scale compute. Teams get the tools they need for experimentation, training, and production inference, with security, observability, and control built in.

We serve solo researchers, startups, and large enterprises. Lightning AI operates globally with offices in New York City, San Francisco, Seattle, and London, and is backed by Coatue, Index Ventures, Bain Capital Ventures, and Firstminute.

Our Values Move Fast: We act with speed and precision, breaking down big challenges into achievable steps.

Focus: We complete one goal at a time with care, collaborating as a team to deliver features with precision.

Balance: Sustained performance comes from rest and recovery. We ensure a healthy work-life balance to keep you at your best.

Craftsmanship: Innovation through excellence. Every detail matters, and we take pride in mastering our craft.

Minimal: Simplicity drives our innovation. We eliminate complexity through discipline and focus on what truly matters.
