In this video I break down how we’re building this at Single Grain, how a fleet of agents sits on top of that brain to handle sales, SEO, content, recruiting, and ops, and why memory systems like Obsidian are critical to making it actually work.

I also walk through what the first 90 days look like (it’s messy), how this system compounds over time, and real examples of how it’s already driving cost savings, pipeline, and inbound from enterprise companies.
