PSA: If you vibe coded your own "B2B SaaS", that means your potential "customers" can vibe code it too.

If you can vibe code a B2B SaaS tool in a weekend with no engineering background, your target customers can do the same, eliminating your moat before you launch. The argument estimates only 5–10% of software tasks are fully vibe-codable by non-coders, meaning products in that range face instant replication risk. Defensibility in software still requires engineering depth that AI copilots do not yet replace.
