# Build every claim for the developer who will publicly check it

> A Hackmamba roundup of DevGTM operators (PostHog, Tinybird, GitBook, Mozilla, APIwiz) converges on one rule — developers verify, so ship proof, not adjectives — and adds sharper tactics on pricing, live metrics, personas, and launch authenticity.

Hackmamba interviewed a spread of developer-GTM operators — Joe Martin (PostHog), Brian Neville-O'Neill (Tinybird), Addison Schultz (GitBook), Tessa Kriesel (Mozilla), Shane O'Connor (APIwiz), and others — and the seventeen "lessons" collapse into one operating principle: **a developer will independently verify what you say, so market as if the check is guaranteed.** Most of the advice — lead with utility, fix onboarding, quotes over logos, honest comparisons — is already the spine of this guide. What's worth stealing is the handful of sharper, testable moves that fall out of taking verification literally.

**Show numbers a stranger can reproduce.** A logo wall proves someone signed a contract once. A live weekly-download count, a public star-history graph, or a deploy counter proves the thing is *used* — and a developer can go check the source. Prefer verifiable, current metrics to social proof they have to take on faith.

**Put a real price on the page, with a cap.** No "contact sales", no vague tiers — an actual number, and where usage-based, a monthly ceiling so nobody fears a surprise bill. Pricing opacity reads to developers as something to hide; transparency is itself a trust signal.

**"Developers" is not one persona.** An indie hacker spending personal money on a weekend evaluation and a platform engineer fitting you into an existing stack with organizational buy-in share a job title and almost nothing else about how they buy. Name which one a given page is for.

**Coordinated authenticity backfires.** A simultaneous influencer launch — the same talking points from ten accounts in one day — is legible as inauthentic to exactly this audience, and reads as *negative* social proof once someone spots the pattern. Substance people can run beats a manufactured chorus. Pair the launch spike with an always-on cadence (changelog, tutorials, product updates) rather than betting everything on the burst.

None of this is a new theory of developer marketing. It's a single, useful discipline for pressure-testing what you already ship: find the one skeptic who will check, and build for them.

**The take**: Pick your most skeptical prospective user and assume they will fact-check every claim in public. Then swap what fails that test: logo walls for live, verifiable numbers (weekly downloads, deploy counts, star history); "contact sales" for a real price with a spend cap; a coordinated influencer push for a thing people can run right now. If the skeptic believes you, the rest follow.
