value-prop-that-converts

Write a developer value proposition that is specific, provable, and free of puffery. Use when the messaging leans on "powerful," "better," "seamless," or "best-in-class," when claims have no proof, or when the same line is supposed to reach both the developer and the buyer.

# The value prop that converts

> "Better" is sloppy thinking. Better how, along what dimension, by how much, proven by whom? Developers test every claim you make. Give them numbers or give them nothing.

**Use this when:** your value prop contains puffery, your claims aren't attributed, or you're trying to make one sentence do the job of two audiences.

## The core idea

Developers have a finely tuned BS detector and they *will* verify you. Specificity is credibility. Every strong dev value prop is: **specific + provable + spoken in their language.**

## Framework: the value-prop rules (Frankl)

1. **Never say "better."** Say better *how*, by *how much*, versus *what*.
2. **Time savings must be specific.** ❌ "saves developer time" · ✅ "8× faster builds, 2 hrs → 15 min" (attributed).
