Improving data collection for robotics.

Munari is quality scoring for robotics data. Our platform processes, annotates, and scores every episode and evaluates operator performance. We then turn those evaluations into actionable feedback, helping teams improve data quality and get more value from every hour of collection. Both cofounders were previously at Hedra (a16z-backed, Series A video model startup). Ramin was also the CTO at StockX (scaling from $0 to $1B+ GMV run rate) and a 3x founder.

Cofounder at Munari

Ramin Keene

CTO of StockX and O’Reilly author, with 20 years building and scaling startups. I built Rover’s first ML platform, designed streaming data infrastructure at Nordstrom, and led infrastructure for training and serving generative video models at Hedra. My work has always been about making ambitious technology work reliably at scale. Now I’m building Munari to do that for physical AI, starting with the quality of the data that teaches robots how to work.
