- Two-year-old startup Mecka AI is finalizing a Sequoia Capital-led funding round that values the company at approximately $500 million.
- The company focuses on collecting and structuring human egocentric motion data to train general-purpose humanoid robots.
- Mecka's business mirrors Scale AI's data annotation model, paying human contractors to record everyday physical tasks.
Mecka AI, a two-year-old robotics-data startup, is in late-stage negotiations to close a new funding round led by Sequoia Capital that would value the company at approximately $500 million. The deal is coming together just months after Mecka announced its Series A, reflecting a rapid acceleration in capital deployment toward the hardware and physical layers of artificial intelligence. Investors are increasingly shifting focus from digital-only models to the data bottlenecks that prevent general-purpose humanoid robots from operating effectively in unstructured human environments.
Mecka's core business model mirrors the data curation and labeling infrastructure pioneered by Scale AI for large language models. Rather than annotating text, Mecka pays human contractors to record everyday physical tasks—such as washing dishes, assembling electronics, or operating power tools—while wearing specialized body sensors and smartphone-based capture rigs. The resulting 'egocentric' datasets capture real-world physics, force feedback, and fine motor coordination, which are highly valuable for training the neural networks that control humanoid physical manipulators.
The Sequoia-led funding round will be used to scale Mecka’s network of human data collectors and build out its automated filtering pipeline, which verifies the quality and anatomical correctness of recorded movements before they are compiled into training libraries. The company hopes to establish its platform as the standard data-clearinghouse for the humanoid robotics industry, providing pre-curated, high-fidelity physical training sets to major hardware manufacturers struggling to gather physical-world datasets at scale.
Humanoid robotics has reached a physical data bottleneck, where further hardware scaling is useless without massive, diverse datasets of physical movements. Mecka’s business model shows that the physical world must be digitized and indexed much like the internet was for text. A $500 million valuation for a startup focusing entirely on physical data collection shows that the next stage of AI competition will be won by companies that control the proprietary datasets of real-world human behavior.
Will Mecka AI successfully close its Sequoia-led Series B round at the reported $500 million valuation?
Still open. When the paper finds out, it will say so here and on the open questions page — including if it got this wrong.
