Build the best products to align with artificial intelligence
We empower the world’s top AI innovators with unrivaled expertise and tools to create, manage, and scale the ultimate data factory for groundbreaking AI solutions.
Advancing AI with the premier data engine
Since 2018, Labelbox has pioneered data-centric AI, turning human expertise into structured learning signals for frontier and enterprise intelligence. We power post-training with RL environments, preference data, evals, benchmarks, and robotics data, grounded in a 2.6M+ Alignerr network producing high-quality training data at scale. For enterprises, we convert proprietary workflows and domain expertise into training data for specialist models that outperform general LLMs on narrow tasks at lower cost. Our mission is clear: turn human knowledge into compounding intelligence, making the learning loop the foundation of an AI teams’ competitive advantage.
Values that bring us together
Our operating principles define how we build world-class AI infrastructure: through high agency, technical excellence, and rapid execution. These aren't just words on a wall - they're the foundation that enables us to solve some of the most exciting challenges in frontier AI development. These principles create an environment where Labelboxers can do their best work.
Make customers win
We find joy in creating solutions for our customers. These solutions empower teams to build impactful machine learning products and services. By working with us, our customers are at the forefront of industrial machine learning.
Seek to understand
The AI industry is growing and evolving rapidly as it begins to transform every industry. We must stay humble and embrace that we have so much more to learn. We seek to understand first so that we build the most impactful solutions.
Craftsmanship
Craftsmanship is the fine balance between perfection and a solution to the given constraints. To be a craftsman is to be consumed in a problem and to create your best expression of work as a result. You can't be a craftsman in every thing, you can only be a craftsman in a few things, but you do those things remarkably.
Enabling breakthroughs in every industry
What we do
Labelbox builds the data engine for frontier AI. We produce the environments, expert signal, and platforms that the world's leading AI labs and enterprises use to train, evaluate, and deploy models — partnering with over 90% of leading AI labs in the U.S.
Horizon
RL environments and evaluations for post-training, covering reasoning, tool use, and computer use across the highest-value domains: autonomous AI research, agent coding, scientific knowledge work, and cybersecurity.
Terra
Full-stack data for robotics and physical AI. Video, trajectories, and rich multimodal annotations collected with purpose-built hardware and AI-powered diversity engines, from pre-training to post-training to evals.
Alignerr
Real-world grounding signal from the smartest people on earth. Our expert network channels 2.6M+ knowledge contributors across 200+ domains and 40+ countries into the reward signals frontier models can't generate themselves.
We believe data will remain a crucial pillar in achieving artificial general intelligence. As AI models become more sophisticated, the need for high-quality, specialized training data will only grow. We're positioning Labelbox to be at the forefront of this evolution, developing new products and services that enable the next generation of AI breakthroughs."
