Meet the Founder

Marc Hoag

I ship production web and iOS apps entirely through vibe coding. When AI tools like Claude Code and Cursor made it possible to build real software without a CS degree, I dove in headfirst. Now I build for clients through Skyriven, or teach them to ship the same way.

Before that, I spent over a decade at the intersection of technology, startups, and law: a VC-backed startup founder, a California-licensed attorney specializing in AI governance, and the Inaugural Chair of the Beverly Hills Bar Association's AI & the Law section. I also publish open source AI tooling, including AIO-Wizard, the template stack behind this site.
