Gated, an email management startup, is shutting down at the end of September, resulting in layoffs for its entire team. The company, which had helped filter half a billion emails and raised funds for charity, cited a smaller-than-expected market for its inbox focus tools as the reason for closure. While the exact number of employees affected wasn't disclosed, the shutdown implies a 100% reduction. Operating in the SaaS/email productivity industry, Gated will open-source its code and assist users in migrating their data before closing.
