Osmosis - Knowledge Diffusion

Osmosis provides a personalized online learning platform tailored for current and future healthcare professionals. The company's core offering delivers a comprehensive suite of educational tools, including visual videos and interactive quizzes, designed to optimize learning and retention. Osmosis leverages adaptive technology to analyze individual student progress, subsequently generating customized quizzes and resource recommendations that align with specific course material across various health disciplines.

The company was co-founded by Shiv Gaglani and Ryan Haynes, who developed the initial concept while both were medical students. Their foundational insight stemmed from a shared desire to significantly enhance the learning process for complex medical topics. Gaglani, having transitioned from medical school to business school, later joined Haynes in dedicating full-time efforts to Osmosis in 2015, building upon their initial vision.

Osmosis serves a broad audience of students within medicine, nursing, and allied health professions who seek to deepen their understanding and preparedness. The company's long-term vision is centered on transforming healthcare education by empowering students to master challenging concepts, improve knowledge retention, and ultimately feel more confident and competent in their academic and professional journeys.

High-Level Overview

Osmosis - Knowledge Diffusion (operating as Osmosis.org) is a leading health education platform that delivers personalized, video-based learning content to millions of medical students, nursing students, healthcare professionals, their patients, and families worldwide.[1][2][5] Founded to empower clinicians and caregivers, it simplifies complex medical topics through over 2,000 engaging videos, high-yield notes, flashcards with spaced repetition, board-style questions, and clinical decision trees, serving over 6 million learners across 195 countries to boost retention, exam performance, and clinical confidence.[2][6][8] Acquired by Elsevier (part of RELX) in November 2021, Osmosis has shown strong growth with an estimated $92.6M annual revenue, 405 employees (up 11% year-over-year), and $6.7M in total funding pre-acquisition.[3][2]

The platform targets current and future clinicians facing knowledge gaps in lectures, boards (e.g., USMLE Steps 1 and 2), and clinical practice, solving inefficiencies in traditional study methods by offering competency-based, algorithm-driven personalization mapped to curricula and certifications.[1][6] Post-acquisition, it integrates with Elsevier's resources for broader impact in inclusive healthcare education, including rare diseases initiatives like "Year of the Zebra."[4]

Origin Story

Osmosis was founded in 2015 by Shiv Gaglani and Ryan Haynes, medical students at Johns Hopkins University, who recognized the excessive time spent curating study resources instead of learning medicine.[5][6] Drawing from the former Khan Academy Medicine team, they built a platform starting with personalized algorithms that scaffold content based on user data, evolving from basic videos to a comprehensive suite including interactive media, institutional integrations, and certification prep.[3][6]

Early traction came from addressing real pain points for med students, expanding to nursing, physician assistants, and global audiences, reaching 800,000+ clinicians by helping them excel in classes, boards, and clinics.[3] A pivotal moment was the 2021 acquisition by Elsevier, advised by William Blair, which scaled its reach while preserving its innovative culture under Gaglani as CEO.[2][4] Celebrating ten years in 2025, Osmosis has refined its all-in-one model for engaging, effective medical education.[7]

Core Differentiators

• Engaging, Video-First Content: Over 2,000 videos simplify complex topics for better comprehension and retention, supplemented by high-yield notes, med tables, and flashcards using spaced repetition—outperforming traditional textbooks.[2][6][8]
• Personalized, Adaptive Learning: AI-driven algorithms customize study plans based on user performance, curriculum objectives, and institutional needs, filling knowledge gaps with daily practice quizzes and clinical decision trees.[1][6]
• Comprehensive Exam and Clinical Prep: Board-style questions, customizable quizzes, and tracks for USMLE, nursing, PA, and specialties reduce exam stress and build clinical skills, trusted by 6+ million users.[6][8]
• Rigorous Quality and Accessibility: Content reviewed by 100+ experts and advisory boards ensures accuracy; mobile app enables on-the-go study at textbook-affordable pricing with institutional partnerships.[6][8]
• Post-Acquisition Innovation: Leverages Elsevier's ecosystem for inclusive initiatives like rare disease campaigns, fostering creativity in diverse healthcare education.[4]

Role in the Broader Tech Landscape

Osmosis rides the wave of digital transformation in medical education, accelerated by edtech demand during remote learning shifts and clinician shortages, where personalized platforms outperform static resources amid rising global healthcare needs.[1][6] Timing aligns with AI personalization trends and post-pandemic emphasis on efficient, inclusive training—300 million affected by rare diseases alone highlight its "rare is common" push.[4]

Market forces like Elsevier's analytics dominance and RELX's global reach amplify Osmosis, influencing ecosystems by bridging academia, clinical practice, and patient education across 195 countries.[2] It shapes standards for competency-based learning, partnering with institutions to integrate curricula, and drives broader impact by producing caring professionals who improve health outcomes.[5][6]

Quick Take & Future Outlook

Osmosis is poised for expansion within Elsevier, potentially integrating deeper AI for predictive analytics, VR clinical simulations, and global expansions in emerging markets.[4][8] Trends like lifelong learning for clinicians, telemedicine growth, and DEI in health (e.g., female 3D models, rare disease focus) will propel it, evolving from student tool to enterprise platform influencing 10M+ users.[4][8]

As edtech converges with healthtech, Osmosis could redefine "learning by osmosis" through supercharged retention tools, cementing its role in building a more caring world—one clinician at a time, from lectures to patient care.[1][5]
