I’m Jason Leinart. I build systems that make marketing and operations smarter.

My path: 10 years in marketing operations → data pipeline architecture → AI implementation. Now I’m building GenAI systems for document analysis, research automation, and workflow orchestration. This is where I share frameworks, build logs, and field notes from the intersection of AI and business systems.

New Here?

Start with my comprehensive guide that walks you through my core thinking and best content. Or jump straight into the Three Horizons Philosophy — my framework for thinking about how AI will transform work across personal, team, and organizational levels.

How I Write

I organize my writing by format rather than topic, which lets ideas flow naturally across boundaries:

⛺ Field Notes - Research logs and paper analysis
🔧 Build Logs - Technical walkthroughs and tutorials
🧠 Mental Models - Strategic frameworks and big-picture thinking

Current Focus

Building production GenAI systems: document analysis with GPT-4, research automation with RAG architecture, and workflow orchestration via Claude Code MCP integrations. Studying for AWS Solutions Architect certification. See what I’m working on right now on my Now page.

Currently open to opportunities in AI implementation, marketing technology, and strategic consulting. If you’re building at the intersection of AI and business operations, let’s talk.
