=== Verdict ===

'''The problem is real and well-evidenced, but "simplest product, fastest to revenue" is misleading.''' The simplicity is in the build, not in trust, adoption, regulatory clearance (MDR), or willingness-to-pay. A decade-old, CE-marked, NHS-deployed Nordic competitor (Klinik) doing ~€1.5M revenue and losing money is the relevant base rate.

'''The defensible version is narrower:''' LLM-based structured history-taking integrated into the GP's existing EHR, positioned as assistant not replacement, with a measurable consultation-time outcome. The PreA RCT (28.7% reduction) is the evidence to build on. Static questionnaires have 25 years of underwhelming RCT results — don't build that.

'''Regulatory risk:''' If the tool suggests specific tests or diagnoses, it's clinical decision support → potentially needs CE marking as a medical device (MDR). Questionnaire-only approach has lower regulatory burden but also lower value.

'''Babylon is a warning:''' Don't position as "AI doctor." Position as "structured history-taking assistant." Underpromise, overdeliver."
