Robotic Training Data at Scale
Sensei has raised $23.1M across 3 funding rounds.
Key people at Sensei.
Sensei was founded in 2024 by Anubhav Guha (Founder) and John Piotti (Founder).
Sensei has raised $23.1M in total across 3 funding rounds.
Sensei helps robotics companies scale and outsource their training data collection. Our hardware platform enables the collection of human-demonstration data at a tenth of the cost and twice the speed of current teleop approaches. Our software platform acts like Scale AI for robotics data: a large network of paid human operators use our low-cost collection platform to fulfill data-generation requests.

Sensei (Sensei Robotics) is a Y Combinator–backed startup building the “Scale AI for robotics training data.” Its mission is to solve the data scarcity problem in robotics by enabling companies to collect high-quality, human-demonstration training data at scale, at a fraction of the cost and time of traditional teleoperation methods. The company offers a combined hardware and software platform: a low-cost, portable teleoperation system that captures human demonstrations, paired with a marketplace of trained human operators (“Senseis”) who collect diverse, real-world data on demand.
Sensei serves robotics companies developing manipulation, mobility, and embodied AI systems—particularly those struggling to generate enough varied, in-the-wild training data to train robust models. By outsourcing data collection to a distributed network of operators using standardized hardware, Sensei dramatically reduces the cost and time required to gather demonstrations. Backed by Y Combinator and already positioned as a critical infrastructure layer for the next generation of AI-powered robots, the company is gaining early momentum as robotics moves from lab prototypes to real-world deployment.

Sensei was founded in 2024 by two MIT engineers, John and Anubhav, who met as undergraduates and later worked together at Aurora Flight Sciences on a DARPA-funded program developing AI for autonomous fighter jet combat. There, they gained deep experience in reinforcement learning and AI for complex, safety-critical systems. John led reinforcement learning efforts at Aurora, while Anubhav returned to MIT for a PhD in robotics, control theory, and machine learning before dropping out to start Sensei.
The idea emerged from their firsthand frustration with how hard it is to collect enough high-quality training data for robotics. Traditional teleoperation setups are expensive, slow, and hard to scale. They realized that robotics was hitting an inflection point—where algorithmic progress was outpacing data availability—and that the bottleneck wasn’t compute or models, but human demonstration data. Their early insight: build a standardized, low-cost hardware platform that could be deployed at scale, combined with a managed network of human operators, to create a scalable, outsourced training data pipeline. This vision attracted Y Combinator, and Sensei launched as part of the Summer 2024 batch.

Sensei is riding the convergence of three major trends: the rise of embodied AI, the scaling of robotics beyond controlled environments, and the growing recognition that data—not just algorithms—is the key bottleneck in robotics. As companies race to deploy robots in warehouses, homes, hospitals, and streets, they need vast amounts of diverse, real-world human behavior data to train robust policies. But collecting this data manually is prohibitively expensive and slow.
Timing is critical: robotics is transitioning from hand-coded control to data-driven, learning-based systems, but the tools for generating that data haven’t kept pace. Sensei fills this gap by providing a standardized, outsourced data pipeline—effectively becoming the “data factory” for robotics. In doing so, it lowers the barrier to entry for robotics startups and accelerates the entire ecosystem’s ability to iterate and deploy.
Moreover, as AI models become more capable and general, the demand for high-quality, human-grounded demonstrations will only grow. Sensei is positioning itself not just as a data vendor, but as a foundational layer in the robotics stack—akin to how Scale AI became essential infrastructure for computer vision and NLP.

Sensei is poised to become a critical enabler of the next wave of robotics and embodied AI. In the near term, its success will depend on scaling its operator network, refining its hardware for broader task coverage, and proving that its data leads to measurable improvements in robot performance. Over the next few years, it could expand beyond manipulation to include mobility, navigation, and multi-modal tasks, potentially integrating with simulation and synthetic data pipelines.
As robotics moves toward general-purpose agents and household robots, the need for diverse, human-like behavior data will explode. Sensei’s vision of tens of thousands of globally distributed “Senseis” collecting data in real homes, factories, and streets could become the de facto standard for robotics training data. If executed well, the company won’t just be a marketplace—it could become the default data backbone for the robotics industry, much like Scale AI did for AI more broadly.
Just as Scale AI helped unlock the value of data for vision and language models, Sensei is betting that the future of robotics belongs to those who can access the best human demonstrations, at scale.
