👋 I’m Justin. I run The SF Grind, The LA Grind, and scout for Headline. I live in LA but spend a lot of time in San Francisco meeting founders, hosting gatherings, and enjoying the wonderful city. If I’m not writing this, I’m probably out on a run.

Welcome back to The SF Grind!

Before we dive in, I want to make sure The SF Grind is giving you exactly what you need, so tell me what you’re focused on heading into 2026.

Let’s get to it.

I’ve personally worked with Ephraim Hintz from their team, and he’s excellent if you ever need a warm intro or trusted guidance on anything legal.
