Block Party

Block Party is a desktop browser extension that checks and tightens privacy settings on social media platforms. It is available for Chrome, Firefox, and Edge. The extension scans a user's social accounts for potential exposures and gives recommendations. It is offered to parents, to people in the public eye, and to people who have dealt with online attacks.

Tracy Chou is Block Party's founder and CEO. Its pre-seed round was led by Charles Hudson of Precursor Ventures. Other investors include Ellen Pao of Project Include and Alex Stamos, director of the Stanford Internet Observatory.
