How a weekend session of vibe coding led to a fully-baked SaaS product
Kevin spends a family-free weekend “vibe coding” and accidentally builds a full SaaS: a multi-tenant lead magnet builder that creates custom, multi-step lead magnets and then generates personalized nurture emails tied to each prospect’s exact inputs. The bigger lesson is not just the tool, it’s the shift in what’s now possible for non-developers with the right AI workflow: Claude Code plus a simple stack (Supabase, Vercel) can compress months of work into days. They also dig into the new marketing floor, hyper-personalization, rising content noise, and why authenticity still wins.
Takeaways
A “dynamic lead magnet” can generate a custom report plus a personalized nurture sequence for every single lead.
Vibe coding is crossing the line from toy demos to real products, if you can iterate hard and think in systems.
The economics are shifting: variable AI costs can be pennies per output, but you must monitor scale risk.
Paid acquisition is getting AI-optimized fast, but competition and creative volume are exploding.
Authentic voice is the differentiator, AI can amplify your take, but slop loses in a noisier world.
