From tracking to experimentation to growth.
99Ways builds reliable tracking, product analytics and experimentation systems, so growth decisions run on repeatable, measurable evidence. We are a small team in Amsterdam; Iman Nazari founded 99Ways in 2023.
How we work
Most businesses can list many things that might improve. The harder problem is finding the few variables that actually matter. We use research to ask better questions, measurement to establish what is happening, experiments to change one important assumption at a time, and engineering to make the answer real.
Open source
posthog-page-experiments
Code-first page experiments for PostHog. It applies A/B and multivariate variants to existing pages, checks eligibility before recording an exposure, lets reviewers force a variant through the URL, and falls back safely when a flag is late or misconfigured. PostHog keeps assignment and analysis.
99hog
A lean WordPress plugin that sends WooCommerce ecommerce events, such as product views, add-to-cart and purchases, to PostHog with a GA4-style event schema and per-event toggles.
Field guides
- Conversion tracking audit – check event meaning, duplicates, identity and attribution before trusting funnel data.
- Experimentation system audit – assignment, exposure, sample-ratio mismatch and inference, with a zero experiment to test the system itself.
- Event tracking plan – from business questions to events, identity, revenue and QA.
- How much traffic an A/B test needs – sample size and test duration by baseline conversion rate and lift.
- PostHog A/B testing on Shopify – run storefront experiments with PostHog feature flags.
- Growth Lever Analytics – connect business economics, measurement and experiments to find the change most likely to drive growth.
