Conversionista
The Nordic leader in experimentation and digital growth, Conversionista helps businesses increase sales, build better products, and validate new ideas, using data, AI, and the scientific rigor of experimentation rather than guesswork.

About Conversionista
Conversionista is the Nordics’ top growth and experimentation consultancy, with 60+ specialists across five offices in Stockholm, Gothenburg, Malmö, Oslo, and Amsterdam. Our CRO teams (A/B testing specialists, designers, and product managers, backed by analysts, user researchers, tracking specialists, and data scientists) run controlled experiments and build data-driven cultures for clients including Kronans Apotek, Aira, and NetOnNet. Conversionista is part of Eidra, a consultancy collective spanning strategy, creativity, and innovation.
How Conversionista works with GrowthBook
Conversionista works with GrowthBook as both strategists and implementers, from setting up and driving experimentation processes to advising on and supporting implementation and setup.
For clients who prioritize data ownership, privacy, and a transparent statistical model, we set GrowthBook up to work with their existing data infrastructure, so sensitive data stays within their own systems rather than being handed to a third party. Because GrowthBook is open-source and built to adapt to a client’s existing setup, it gives our clients real flexibility, and we add value by helping them get the most out of the platform.
Our engagements typically go beyond the initial setup. We build the experimentation program around it, research, hypotheses, and the ongoing analysis that keeps testing embedded in how a team makes decisions long after we’ve handed things over.
