About Cro Metrics

Experiment-led growth for scaleup marketing teams

Cro Metrics builds its work around experiments, with the aim of driving growth for marketing teams. It works with them to build programs in which changes are tested before they are scaled. The firm says its approach rests on continuous validation: build, test, learn, optimize and scale what works. Experimentation has been its work for nearly two decades, and it reports more than 35,000 experiments across industries. Its clients are mid-market and enterprise companies in online retail, software-as-a-service, healthcare, nonprofit work and hospitality.

Marketing and conversion rate optimization

The marketing service starts with conversion rate optimization to support demand generation and customer acquisition. The team tests audiences and ad creative, launches campaigns, and works to raise return on ad spend and lower customer acquisition cost. The company says it connects this work to business measures such as customer lifetime value, acquisition costs and revenue per visitor, and that it does not dress up attribution models or inflate return figures.

Product, engineering and data work

On the product side, the firm provides rapid-response engineering support to speed up optimization programs. It gathers customer feedback to help a business build the features its customers want, audits data maturity, and builds analytics and insight programs. It also runs testing and automation for email and SMS messages, so that the messages sent to customers are relevant to them.

Website design, strategy and working rhythm

Cro Metrics also designs and builds websites and offers strategy and consulting. The company describes a working rhythm of weekly or biweekly syncs, shared roadmaps, benchmarks for impact, and steady idea generation, with quick wins and longer-term plans both tracked. Case studies on its site describe a conversion lift for Bombas, a website redesign for the Sierra Club, revenue work for Home Chef and personalized experiences for Calendly.
