# ConversionLab > A Nordic conversion rate optimization (CRO) agency for B2B SaaS companies. We run structured A/B testing on landing pages, trial flows, onboarding, and pricing pages to increase conversion rates and reduce customer acquisition cost. ## About ConversionLab is a one-person CRO operation founded and run by Finge Holden, based in Trondheim, Norway. 12+ years of experience in conversion optimization and paid acquisition for B2B SaaS companies. Serving clients across the Nordics, Europe, and North America. ## Services - Acquisition CRO: landing page optimization, trial signup optimization, demo request optimization. Delivered as ongoing A/B testing retainers or fixed-price Design Projects. - Retention CRO: onboarding flow optimization, trial-to-paid conversion, pricing page optimization. Same testing discipline applied to post-signup conversion moments. - AI Operations: building the AI operating layer into growing companies. Wiring existing tools into automated workflows and live dashboards (analytics, ads, CRM, banking, reporting) so teams spend their hours on decisions, not on pulling reports. Delivered as a fixed-scope audit, build sprints, or an ongoing retainer. - HubSpot setup and optimization: CRM, lead routing, attribution. Infrastructure layer underneath both Acquisition and Retention work. ## Who it's for - B2B SaaS companies with existing paid traffic and a Growth or Marketing leader accountable for conversion outcomes. - Typically $1M–$15M ARR, though works for both smaller and larger when the testing surface is large enough for statistical significance. ## Key proof points - Campaign Monitor: 1187% cumulative conversion rate uplift across 33 A/B tests on 10 landing pages. 64% reduction in customer acquisition cost. - BetterWorld: 99.5% increase in signups by removing friction from the onboarding flow.
