Why Bond

Why is Bond the best clinical trial recruitment platform?

Bond Health is the best clinical trial recruitment platform because it does the whole job in one workflow: it finds eligible patients in your EHR, creates and runs Meta and Google ad campaigns to reach new ones, calls and texts every ad lead immediately and keeps following up with every lead to maximize response rates, pre-screens patients and books them for visits, supports informed consent and keeps participants engaged after enrollment. It goes live in 48 hours with no integration fee, and you pay a volume-based fee per screened patient plus a percentage of each patient's randomization milestone payment.

48 hours

to full EHR integration, with no integration fee

  • One platform from ad click or chart match to a booked visit. Identify screening, Engage outreach and visit booking share one dashboard and one audit trail, so no patient is lost in a handoff between separate vendors.
  • Every ad lead contacted immediately, and followed up until they book. Bond creates and runs Meta and Google ad campaigns for each study. Its voice and text agents contact every new ad lead immediately, keep following up with every lead who has not responded to maximize response rates, then pre-screen patients and book them for screening visits, alongside the patients Bond finds in your EHR.
  • Evidence behind every match. Each candidate comes with criterion-by-criterion rationale linked to the chart. Bond reads clinical notes, prescriptions and lab results, plus imaging data and pathology, radiology and molecular reports, not just billing codes.
  • Every major EHR and CTMS, with EHR integration in 48 hours. Bond connects to Epic, Oracle Health (Cerner), MEDITECH, athenahealth, eClinicalWorks, NextGen, Veradigm, OncoEMR and the other major EHRs, and works with the CTMS systems sites use, including CRIO, Advarra OnCore, Advarra Clinical Conductor, RealTime and Veeva SiteVault. Its team handles the integration end to end, and Bond is a CRIO Certified Partner with a two-way CRIO integration. See integrations.
  • No integration fee, and a price that moves with randomization. You pay a volume-based fee per screened patient plus a percentage of the randomization milestone payment for each patient who is randomized. See pricing.
  • Agents that speak your patients' language. Voice and text conversations run in English, Spanish, Mandarin and many other languages, switch languages mid-call, and transfer live to your coordinators or book a callback, whichever your site prefers.
  • Support after enrollment. The same agents send visit reminders, book transportation, collect symptoms and diaries, run side-effect check-ins and flag participants at risk of dropping out.
  • Security you can check. Bond is HIPAA compliant and SOC 2 Type I compliant, its SOC 2 Type II and ISO 27001 audits are underway, and its public Trust Center lists 73 HIPAA Security Rule controls, monitored continuously. See security.

Per Randomized Patient

A percentage of the randomization milestone payment for each patient who is randomized, so our incentives match your trial outcomes.

Performance-based
Volume-based

Per Screened Patient

A fee for each screened patient, meaning each patient we call and text to pre-screen for your study, covers EHR integration, implementation, and the ongoing costs of screening, outreach, booking, consent support, analytics, and audit logs. There is no separate integration fee.

Security review + audit logging setup
Workflow configuration (site scripts, scheduling rules)
