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

just saying, @zackgilbert is the best cofounder a boy could have.

I write software from my apartment in Chicago, IL.

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 2015, I co-wrote the Independent Consulting Manual, a book about how to build a six-figure solo business, with a group of friends and colleagues.

In early 2016, I was a regular guest on Paul Jarvis and Jason Zook's Invisible Office Hours podcast, where we documented the creation and launch of ofCourseBooks.

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