Sanity × Amplitude
Sanity x Amplitude: From 4 Pages a Month to a Self-Serve Growth Engine
19% more traffic YoY in first full quarter on Sanity
Engineering bottleneck to marketer autonomy
Why it works
The case study earns its New Capability tag because A/B testing on the website was practically impossible before, not just slow, and Amplitude's own irony of selling experimentation tools while unable to run experiments on their own site sharpens the before-state dramatically. The quote about a 25% lift in signup clicks from the first self-serve A/B test is specific and attributable. This story also has a strong Efficiency thread since engineers were freed from routine tasks, but the headline leads with net-new abilities, so New Capability wins.
Steal this
Use the vendor-as-own-worst-customer irony: Amplitude sells experimentation tools but could not run experiments on its own site. That contradiction makes the before-state instantly credible and the resolution satisfying.
