What You'll Learn
- "Vibe coding": how non-technical founders build SaaS with AI
- Content-first growth: why Jack built an audience before his product
- The "selfish product" filter: only build features you personally need
The Story
Jack Fricks calls himself a "vibe coder" — someone who describes what they want in natural language and lets AI translate it into code. Before Cursor and Claude, he had zero programming experience.
Seven months after starting Postbridge, a social media scheduling tool, he hit $18K MRR. Alone. No ad spend.
The Content-First Strategy
Before writing a single line of code, Jack built a Twitter audience. His previous project, CuriosityQuench, hit 100K+ downloads — all from his Twitter presence.
The formula: ship content → build audience → audience tells you what to build → build that.
When he noticed his audience struggling with social media scheduling, he built Postbridge to solve that exact problem. He already had customers waiting.
How "Vibe Coding" Actually Works
Jack doesn't write traditional code. His workflow:
"Cursor is my merciless mentor. It doesn't judge me, but it also won't make decisions for me."
The "Selfish Product" Filter
Every feature in Postbridge passes one filter: "Would this make MY posting workflow faster today?"
This sounds narcissistic but works brilliantly:
- No feature bloat (you can't BS yourself)
- Every feature is battle-tested (you're the first user)
- Product-market fit is automatic (you ARE the market)
The Anti-Notification Philosophy
Ironically, Jack — who built a social media scheduling tool — turned off all phone notifications. He checks social media on his schedule, not the algorithm's.
His argument: "If you're building a tool to help people manage social media, you better understand what healthy social media use looks like."
