The California Startup Finance Library

Every guide and article we've written, organized by topic. Start with the essential guides in a category, or browse the latest articles as they publish. No feed to scroll, just the answers, sorted the way founders look for them.

HOW THIS IS ORGANIZED

A library that grows, not a blog feed

Each category has two parts. Essential Guides are the permanent, evergreen hubs and pillar guides, the foundation. Latest Articles is where new supporting articles appear automatically as we publish them, newest first, each tagged to its parent topic. The essentials stay put; the library keeps growing beneath them.

Build note (delete on live site): In each category, the Essential Guides grid is hand-placed and permanent. The Latest Articles list is a dynamic zone, in Divi, build it as a Blog or Query/Loop module filtered to that category, sorted newest-first, limited to ~4-5 posts, showing title, date, and parent-topic. The example rows here are placeholders to show the layout; your CMS generates the real ones. The View All link points to that category archive.
