How Was Third Chair Started?
Third Chair was founded in San Francisco, California, and is backed by Y Combinator (Spring Batch 25). The company has recently launched under a new brand, focusing on building agents for in-house legal teams—particularly in the media and entertainment sectors—to automate the process of web crawling for IP infringements, collecting evidence, and recovering licensing revenue at scale.
What Problem Does Third Chair Solve?
Rights holders often struggle to keep track of where and how their intellectual property is used in advertising. Manual monitoring is labor-intensive and can result in lost revenue opportunities. Third Chair addresses this challenge by:
- Continuously monitoring ad content for unauthorized or unlicensed IP use
- Prioritizing high-value cases for action
- Providing tools to collect and manage licensing revenue efficiently
This allows legal teams to focus on high-impact recoveries instead of repetitive manual tasks.
Leadership Team
Third Chair’s leadership includes David Teather, who serves as an advisor. The company is composed of a small team (2-10 employees) with expertise in legal technology and media rights management.
