Notion, a freemium productivity and note-taking web application, completed the acquisition of Skiff, n email service startup company and collaboration tool. Financial terms were not disclosed. "I started working on Skiff after a trip I made to Russia as a graduate student. I was frustrated with the limited tools I had at my disposal while I was traveling, but also inspired by the challenges of working with people in different languages and time zones, and with varying security constraints. When I started Skiff, Jason was the first person I reached out to. We met six or seven years ago while planning a Stanford hackathon. He has an incredible skill set and he’s the hardest-working person I've ever met," Andrew Milich, Skiff Co-Founder.
