Hi, I'm Zack (with a k).

I build tools on the internet that help people organize their lives.

In 2005, Nick Adams and I created one of our first tools: billQ, a bill reminder system that has sent over a million reminders that have helped avoid paying millions of dollars in late fees.

In 2010, I became an active member of the Chicago tech community, when I co-founded Technori with Seth Kravitz, Mark Bertrand and a few others. That same year I also co-founded a semi-regular monthly tech meetup, called Chicago.concat() with Daniel Zarick. Both are still active and helping to foster participation in the community.

In recent years I've helped multiple startups, like Highrise, Umba, Perfect Audience, Mercaris and others, build custom software solutions that help their customers be more successful.

If you'd like to receive random short emails from me every week, you should join my mailing list. If you'd like to follow along with my travels, follow me on Instagram. If you'd like help finding great airline deals from Chicago, follow me on Twitter. Or you can always just say hi by emailing me.
