Why set up a separate brand to funnel COVID trial business to TrialSpark? From their own site, TrialSpark is a VC-backed company which primarily runs trials for major drug companies to recruit more patients with painful chronic conditions (like Astma, COPD, Diabetes, inflammatory, skin problems etc, but not cancer)for drug studies. The highly profitable medical areas are clearly attractive for Pfizer, but the sales pitch of TrialSpark is to identify high cluster areas of a disease in small communities, recruit community doctors and incentivize them to attract patients to drug studies with 1.9x higher than usual conversion rate.<p>So why the separate brand?
