What NEJM Knowledge+ does
NEJM Knowledge+ is a medical education platform that provides adaptive, question-based board exam preparation for physicians preparing for specialty certification in Internal Medicine, Family Medicine, and Pediatrics. Originally developed by NEJM Group, a division of the Massachusetts Medical Society, the product was acquired by AMBOSS in March 2025 as part of a €240 million financing round backed by KIRKBI, M&G Investments, and Lightrock. The core technology stack is a cloud-based adaptive learning platform that personalizes the question sequence based on individual learner performance, delivered through the AMBOSS QBank App on iOS and Android and integrated with the AMBOSS Medical Knowledge Library, which contains over 2,000 physician-curated, disease- and symptom-based articles used for both deeper study and point-of-care clinical reference.
The product surface spans three specialty board review subscriptions sold on an annual or multi-year basis directly to clinicians through AMBOSS's self-serve website and mobile apps, plus a separate free Pain Management and Opioids CME/CE training module delivered via a dedicated NEJM Group portal (securepmmcme.nejm.org). The 10-hour CME module satisfies the DEA's one-time eight-hour training requirement for DEA-registered practitioners and functions as a lead-generation and retention funnel rather than a direct revenue source. Marketing is delivered through co-branded NEJM Group and AMBOSS channels, including dedicated product pages, email outreach, and phone-based customer support, with no named enterprise or institutional contracts visible in the data.
Post-acquisition, NEJM Knowledge+ operates as a product within AMBOSS rather than as an independent company, with NEJM Group retaining involvement through the co-branded CME module and continued brand association. The operating footprint is small (1-10 employees listed in the firmographic data), consistent with NEJM Knowledge+ functioning as a focused product unit inside the larger AMBOSS organization rather than a standalone business.

NEJM Knowledge+ competitors and assessment
Company assessmentDirect peers
- AMBOSS: The acquiring platform and now the direct operating home of NEJM Knowledge+. AMBOSS provides the QBank, Knowledge Library, and adaptive learning engine that power NEJM Knowledge+ subscriptions, making it the most direct comparable.
- UWorld: Largest US medical board prep QBank competitor serving USMLE, Step 1/2/3, and specialty board review. Directly competes for the same resident and board-eligible physician learner with similar subscription-based, self-serve delivery.
- BoardVitals: Specialty board review QBank platform offering question banks across a broad range of medical specialties with similar subscription pricing and self-serve model. Competes head-to-head in Internal Medicine, Family Medicine, and Pediatrics review.
- TrueLearn: Board-style question bank platform focused on USMLE and medical specialty boards with adaptive learning features. Closely comparable in product mechanics and target audience of medical residents and fellows.
- Rosh Review: Board-style QBank with question banks across medical specialties and a focus on adaptive learning and personalized study plans. Now part of the USMLE-Rx family under Wolters Kluwer.
Broad incumbents
- Lecturio: Broader medical education platform combining video lectures, QBank, and study planning across medical school and board prep. Overlaps with NEJM Knowledge+ on board review but extends to full medical school curriculum.
- Kaplan Medical: Established test prep incumbent offering USMLE and medical board review courses, QBanks, and live instruction. Competes for the same resident learner base with a much broader portfolio.
- Osmosis (Elsevier): Visual medical education platform with video libraries, questions, and study tools across the full medical curriculum. Now owned by Elsevier; overlaps with NEJM Knowledge+ on integrated content + QBank for board prep.
Emerging players
- Sketchy Medical: Visual storytelling-based medical education platform with USMLE, COMLEX, and clinical content. Adjacent in learner segment with a differentiated memorization methodology rather than pure QBank approach.
- Mayo Clinic Board Review: Institutionally-branded board review content and courses from Mayo Clinic, leveraging a similarly prestigious medical brand. Overlaps on specialty board review content quality and brand-driven credibility positioning.
