Hey there, I’m Alexander.

I’m interested in how software can better serve people’s daily lives.

My experiments often involve designing and developing many ideas — some of which I build into publicly available products, which further informs my research. Below is a compendium of my research areas, projects, and products.

My work is graciously supported by the community — if you want to join us, see memberships.

The future of the operating system

In my current work, I am exploring new and renewed ideas for how personal computing can better support people’s lives, expanding opportunity, agency, curiosity, and creativity.

This work is primarily shaped by exploring the “operating system of the future,” and creating an experimental new environment for personal computing.


These projects experiment with the concepts from my research on the future of the OS.

Reimagining email

My career began with reimagining email and finding ways to build that vision on top of the existing email protocols.

Mail Pilot is an email client that introduced new perspectives and useful features to email in 2012, including reminders (later adopted by other apps as “snooze”). After a record-breaking Kickstarter campaign, it went on to become the #1 paid app in the Mac App Store at launch. It is available today as a native app for macOS and iOS.

Throttle is a service that introduced sender-specific addresses in 2015 to give email receivers fine-grained oversight and control over the transactional and bulk email headed their way, and is often turned to as a home away from the inbox for less urgent email.


These products have come from of my research and experimentation in email.

My work is independent research — more on that here.

It is graciously supported by the community. Supporting members get access to my Member Magazine, member-exclusive demos, and other perks.

Consider becoming a member — you'll receive all the member exclusives, and help make more of this work happen, most of which is published for members and non-members alike.

If you’d like to make a bigger contribution to support my work, you can become a sponsor of WonderOS, my current research project.
