Recruits participants for clinical research studies

Overview

Clariness recruits participants for clinical trials on behalf of pharmaceutical companies, biotechnology firms and research organizations.

ClinLife gives potential participants a place to explore research opportunities, while sponsors use the company's software to organize enrollment projects. It earns fees for enrollment services, with commercial models covering technical setup, outreach media and performance delivery, plus participant-engagement support.

Simplify's take

What believers are saying

  • Delivery spans markets: Clariness reports ClinLife-supported randomizations in 60-plus countries and 35-plus languages.
  • Development gets funding: Clariness's Germany-based online-marketing student posting includes a development budget; remote, part-time, fixed-term, German-university enrollment required.
  • Patient calls avoid selling: Clariness's Canada French/English medical customer-service freelancers screen patients rather than conduct sales calls; project-based.

What critics are saying

  • Enrollment depends on sites: Clariness requests referral processing within 3-5 working days and escalates delayed responses.
  • Evening availability is requested: Clariness's patient-support contractors in Canada need daytime availability and evenings when necessary; French/English, freelance/project-based.
  • Languages gate entry: Clariness's fixed-term, part-time working-student marketing role requires German C2 and English C1/C2; remote within Germany.

What makes Clariness unique

  • Forecasting uses comparable studies: Clariness's ClinSight benchmarks protocols against real-world studies by indication, country and patient population.
  • Creative access is role-based: Clariness's ClinStudio limits access to authorized sponsor teams, approved investigators and sites.
  • Referrals use live handovers: Clariness's ClinLife schedules patient visits or transfers screened patients directly to study sites.
