Hello World

Welcome to my blog. I'm Justin Tannenbaum — founder of JET Ventures, a holding company for digital and boring businesses.

I spend most of my time building and running AppStream Studio (an AI focused application development studio) and aiventic.ai (AI agents for field service management).

Fresh Start

I originally ran this blog on Ghost. It worked fine, but I wanted full control — so I rebuilt it from scratch on my own stack. Next.js, markdown files, deployed on Vercel. No CMS, no dependencies I don't own. Just code and content.

If you're reading old posts, they were migrated over. If something looks off, that's why.

What I'll Write About

This blog is where I share what I'm learning as I build. Expect posts on:

• Product management — how to ship things that matter
• AI development — practical lessons from building AI products
• Business building — the messy reality of starting and running companies
• Commercial real estate — what I'm learning as I invest in CRE
• Bitcoin — why I'm long BTC and what I'm paying attention to
• Tennessee Vols — because you can take the boy out of Knoxville, but you can't take Knoxville out of the boy

Why Write?

Writing forces clarity. If I can't explain something in a blog post, I probably don't understand it well enough. And if something I share helps someone else avoid a mistake or see an opportunity, even better.

More soon.
