Notion, a collaboration software company, has acquired Cron, a calendar for professionals and teams.

Notion plans to leverage Cron’s experience building products and expertise in how people organize time.

“At Notion, our mission is to make software toolmaking ubiquitous,” said Ivan Zhao, Notion’s CEO. “Last year I switched to Cron for my calendaring and was so impressed by the craft behind this product. I’m super excited to see Notion and Cron come together to bridge synchronous and asynchronous work, and help people collaborate more easily on whatever is most important to them.”
