Thanks for follow-up. You're absolutely right that there's a distinction between privacy and anonymity. However I just want to clarify that my decision to keep a low personal profile online stems from a deep belief in privacy, not secrecy.
To give you more context about the project: Stalwart Labs was indeed started and is currently led by a single developer: myself. I have over 30 years of experience working with email technologies and have previously founded three email-related companies.
That said, I’m not working entirely alone. While I’m the core developer and founder, there are others involved in Stalwart Labs today handling support, sales, and maintaining smaller parts of the codebase (mostly changes required by clients). My plan is to continue leading development myself until the project reaches version 1.0, which I hope will happen later this year. After that milestone, the goal is to gradually expand the development team, particularly to support work on a Rust-based webmail and calendar interface that will complement the mail server.
Stalwart’s development has been largely self-funded, aside from two NLNet grants. I’ve been growing the team organically and intentionally. While I have been approached by two VC firms, I’ve chosen to decline their offers. Not just to avoid external pressure (and stress), but also because some proposed directions conflicted with promises I’ve made to the community. For example, there have been suggestions to move some open-source features behind a paywall, which I’m against and promised the community never to do.
As for enterprise support, yes, Stalwart Labs offers an enterprise license that includes premium support services. And regarding adoption, I'm happy to say that there are currently a few hundred enterprise clients using Stalwart in production. While I would need the clients' permissions to share their names, I can say that Mozilla Thunderbird is one of them. They’ve publicly announced their upcoming launch of thundermail.com, which is powered by Stalwart.
I hope that gives you more clarity and confidence in the project. Thanks.
