Model patient and prescriber decisions
before any market activity.

Brox builds 1:1 digital twins of real patients and verified healthcare professionals from hours of AI-moderated interviews. Drug adoption, prescribing intent, copay sensitivity, M&A theses: predicted, not guessed, with the audit trail your compliance team requires.

What pharma teams use Brox for

Drug adoption & patient journey simulation

Awareness, trial, adherence, segmented by condition, demographic, and provider type.

HCP prescribing behaviour

Formulary changes, black box warnings, competitive entries, safety data releases, treatment switching triggers.

Pricing & market access

Copay sensitivity ($10 to $250), price framing, reimbursement scenarios, comparator dynamics.

Launch messaging optimisation

DTC and HCP message variants tested in days, not quarters.

HCP channel & detail-aid effectiveness

Peer-reviewed journals vs sales-rep visits vs KOL webinars, scored on prescribing intent.

Validated outcomes

Launch messaging

36 message variations across 4 segments tested in 3 days. "Clinically proven" framing outperformed "life-changing" by 28% among HCPs.

Treatment feature prioritisation

14 attributes across 3 segments and 450 twins. "No routine blood monitoring" outperformed "superior efficacy" 2:1.

HCP channel test

10 channels across 300+ HCP twins and ~9,000 simulations. Peer-reviewed journal content outperformed sales-rep visits 2.5x. KOL webinar plus peer journal combo reached 31% positive prescribing intent vs 12% baseline.

GLP-1 adoption study

528+ twins. 73.6% said "I don't need it." 81.3% would abandon with side effects. Only 4.6% cite cost as the barrier.

Built for regulated work

You never hand Brox your patient data. The panel behind every answer is our own, so there's no PHI in the system and Brox isn't a HIPAA covered entity. Adverse events that surface in interviews are captured and escalated, and panels can be GxP-aligned where a use case requires it.

Our SOC 2 Type II audit is complete, with the report available to clients under NDA once issued.

Whatever your medical, legal, and security teams need to assess us, we'll provide it.
