I'm Jon Warnow. I help organizations use technology to scale impact.

I'm a technologist, trainer, and entrepreneur with 15+ years helping mission-driven organizations adopt powerful technology and scale their impact. I've co-founded a global climate nonprofit, scaled a civic tech company from first employee to 50+, and helped build a modern organizing platform from the ground up.

2022 – present

Led product development, sales, and client onboarding from zero. Designed training programs and hands-on support to help non-technical teams adopt conversational AI workflows and personalized media tools. Managed the full lifecycle: strategy, compliance, go-to-market, and client success.

2017 – 2021
VP of Sales & Client Success
GetThru

First employee at a peer-to-peer communication platform. Built the sales and client success organizations from scratch, growing the team from 1 to 50+.

2016
Regional Digital Organizing Director
Bernie Sanders Presidential Campaign

Provided digital organizing support to state-level campaigns. Led large-scale volunteer trainings, recruiting hundreds of supporters and converting them into active organizers on the spot -- training them directly on the campaign's technology tools and turning first-time attendees into team leaders running their own phone banks and canvasses. Managed the development and implementation of a peer-to-peer email recruitment tool. Produced videos to support volunteer recruitment and grassroots organizing.

2008 – 2015
Co-Founder & Digital Director

Co-founded a global climate organization and grew it to a staff of 120+ with millions of supporters worldwide. Built custom technology platforms and digital infrastructure that enabled the team and thousands of volunteers across dozens of countries to organize effectively at scale. Trained and supported users across technical skill levels. Produced documentary films (Do the Math, Disruption) used as organizing tools by activists globally.

We're in an exciting moment for builders. Agentic engineering tools like Claude Code have made it possible to move from idea to working product faster than ever before. These are a few of my early experiments in this space.
