GrowthCRO is a U.S.-based conversion optimization consultancy founded by Russ Painter with a practitioner-led model: experimentation, personalization, and analytics shipped as one program rather than disjoint projects. Their public story highlights more than a decade leading optimization and personalization programs at large digital brands including Ancestry, Lendio, Assurance IQ, and Life360 before launching GrowthCRO to partner with select clients on full-funnel programs. The firm organises around specialized pods—analytics, experimentation, personalization and experience design, implementation and development, and strategy and enablement—so work can flex from technical audits to embedded experimentation partnerships. Their stated philosophy is that durable growth comes from structured experimentation on trustworthy data, with a collaborative process covering discover, diagnose, design and test, then scale and enable.
