Hello world! I’m Jeremy.

I’m based in San Francisco where I work on projects that bridge the gap between bits and atoms.

My free time is spent with my two daughters, playing & building pinball machines, repairing vintage computers, and dreaming about SPILFs (side-projects I’d like to finish).

The fastest way to reach me is by sending me a message on twitter at @jherrm, but feel free to send me an email at jeremy@jherrman.com.

Founder & CTO 2019 – 2022

I was founding CTO at Volition, where we developed the largest marketplace of industrial components built just for hardware teams. Our catalog is powered by a data pipeline capable of handling millions of products with complex attributes and related assets.


Founder & CTO 2013 – 2019

At Plethora, we built software-driven factories using multi-ton CNC machines and pioneered instant manufacturability feedback plugins for CAD software. As founding CTO, I created the initial prototypes of our core technology, built and led a broad engineering team, assisted in fundraising, and guided IP portfolio development.

Founder & CEO 2008 – 2012

Chogger was a comic creation tool that grew to over 30K monthly users.

As founder & CEO, I formulated the initial idea, built the founding team, and prototyped the initial version used to raise a seed round. I also coded the entire comic creation tool and designed the site to match the look and feel of old school comics.

Chogger website used fun CSS tricks to create an authentic comic book style.

Chogger let you build comic strips by adding photos, drawings, and speech balloons with real comic book fonts. Check out this video to see how it worked:
