What are some early indicators of Shortwave's product-market fit?

Right now, we’re seeing a lot of positive signs specifically from former Inbox by Gmail users. Inbox by Gmail was shut down in 2019 by Google and had a large set of very devoted fans. Ultimately, they’ve folded some of Inbox's features into Gmail, but there’s still a lot that hasn't been replaced in Gmail.

When we launched Shortwave, there was a large contingent of these former Inbox by Gmail users who really connected with our product. Many of them are even thanking us for bringing back Inbox, which is not exactly how we frame our product—they're inspirations from Inbox, but we’re trying to evolve even the things that Inbox brought. I would say the earliest signs of product-market fit we're seeing are with that group, that contingent of people.
