Better how, along what dimension, by how much, proven by whom? Developers test every claim you make. Give them numbers or give them nothing.</p>\n</blockquote>\n<p><strong>Use this when:</strong> your value prop contains puffery, your claims aren't attributed, or you're trying to make one sentence do the job of two audiences.</p>\n<h2>The core idea</h2>\n<p>Developers have a finely tuned BS detector and they <em>will</em> verify you. Specificity is credibility. Every strong dev value prop is: <strong>specific + provable + spoken in their language.</strong></p>\n<h2>Framework: the value-prop rules (Frankl)</h2>\n<ol>\n<li><strong>Never say \"better.\"</strong> Say better <em>how</em>, by <em>how much</em>, versus <em>what</em>.</li>\n<li><strong>Time savings must be specific.</strong> ❌ \"saves developer time\" · ✅ \"8× faster builds, 2 hrs → 15 min\" (attributed).</li>\n<li><strong>Two kinds of time, speak to both:</strong>\n<ul>\n<li><strong>Chronos</strong> (Alpha Dev): clock hours saved per week.</li>\n<li><strong>Kairos</strong> (Empowered CTO): calendar time, weeks off a release cycle, competitive edge.</li>\n<li>The same product must land both. <em>\"Release fast or die\"</em> worked for developer <em>and</em> CTO.</li>\n</ul>\n</li>\n<li><strong>Every claim needs proof.</strong> A demo is the <em>weakest</em> proof (ideal conditions). An <strong>attributed testimonial</strong> (name + title + company + number) is the strongest. Anonymous quotes are assumed invented.</li>\n<li><strong>Sell the category, not the solution.</strong> Talk about the problem and the need for \"a tool like this\"; don't proactively pitch features; it trips developer defenses.</li>\n<li><strong>Never \"pleased to announce\" / \"excited to share.\"</strong> No one cares how you feel.</li>\n</ol>\n<h2>Framework: the three dimensions of a dev value prop (Czakon)</h2>\n<p>A complete value prop answers all three, fast:</p>\n<ul>\n<li><strong>What is it?</strong>: category / known-incumbent comparison / plain statement (\"a Datadog alternative,\" \"CI for monorepos\").</li>\n<li><strong>For whom / what use case?</strong>: the ICP and the job (from <code>who-is-this-for</code>).</li>\n<li><strong>Why you over the 10 alternatives?</strong>: the legitimate, provable reason to exist.</li>\n</ul>\n<p>Headline = <em>what is it.</em> Subhead = <em>for whom / what job.</em> For dev tools, weight the <strong>how</strong> over the <strong>why</strong>.
