About 99Ways
99ways is a Netherlands-based conversion rate optimization and experimentation agency. We help ecommerce, Shopify, SaaS, and growth teams turn user behavior into measurable improvements through research, funnel analysis, A/B testing, UX and conversion optimization, and careful implementation. Our technical work includes PostHog, analytics and tracking infrastructure, event design, experiment measurement, and growth reporting. We connect strategy with execution: identify the highest-impact friction, define a testable hypothesis, implement the smallest reliable change, and analyze results against business goals. 99ways also supports teams that need clean measurement foundations before scaling experimentation, including funnel instrumentation, conversion definitions, and data-quality checks.
