About Hemlock
Where is Hemlock headquartered?
Hemlock is headquartered in Los Angeles, CA.
What does Hemlock do?
Force-sensing wristband for training robotic AI
What problem does Hemlock solve?
Today's robots learn from video, which shows where a hand went but not how hard it gripped or pressed, so foundation models for robotics lack the force data needed for fine, contact-rich manipulation.
What's Hemlock's solution?
Hemlock makes a wearable bracelet with dry electrodes that reads the electrical signals driving muscle force, turning everyday human work into force-labeled demonstration data to train embodied AI.
What makes Hemlock different?
It captures actual measured force finger-by-finger rather than a video-inferred estimate, needs no cameras, mocap rigs, or teleoperation, and delivers data pre-synced to footage in the format teams already train on.
What makes Hemlock notable?
Founded by Julian Olschwang, a teenage inventor who won the Broadcom MASTERS Lemelson Award for Invention and a Davidson Fellowship for an earlier sign-language-translating glove before starting this YC-backed company.
