The most overlooked growth bottleneck across marketing, product, and engineering teams is latency. It’s not a theoretical issue or a vanity metric. It’s a direct, measurable drag on performance at every stage of the user journey.
Most teams focus their growth efforts on messaging — copy, creative, onboarding flows. But the speed at which users access that message is usually treated as a technical afterthought, dealt with reactively, relegated to the bottom of backlogs instead of acted upon proactively as a first principle and a first class requirement. That’s the real problem. How fast someone can engage with what you’ve built isn’t just an engineering detail. It’s a core business lever that drives conversion, engagement, and trust.
Latency is one of the few factors that improves performance across the entire funnel. It lowers bounce rates, increases engagement, and lifts conversions without needing to guess at intent or segment audiences, which are guesses, whereas latency is precisely quantifiable.
Start with real-world metrics like Time to First Byte, Largest Contentful Paint, and Time to Interactive. Then layer that data against funnel performance analytics to see where latency is quietly eroding outcomes.
Most fixes are straightforward: tune the backend, preload key assets, optimize edge caching, and load scripts and styles intelligently. These improvements aren’t just technical wins — they multiply the impact of everything else you’re already doing. They are outcome multipliers.
The truth is, that speed accelerates everything, and treating it as just technical debt leaves free (if not guaranteed and compounding) growth on the table.
