Verdict

Conversion Sciences is a strong specialist candidate for companies that want research, hypothesis development, design, analytics, development, and A/B testing under a senior CRO lead. It has operated since 2007 and publishes cases across ecommerce and lead generation, including Boingo stack integration. Independent review and pricing detail are thinner than the best-documented alternatives, so references are important.
