Software testing platform BrowserStack has announced a $125 million ESOP and share buyback program, its third such initiative. This program will benefit over 500 current and former employees, as well as early investors, bringing the company's cumulative buyback value to over $275 million. Funded entirely through internal accruals, the move supports BrowserStack's expansion into a comprehensive End-to-End testing platform and its strategy of acquiring developer tool startups.
