Company profile
researched Aug 2026Osmosis (osmosis.org) is a US-based digital health education company that produces short-form, illustrated video content and study tools for medical, nursing and allied health students, practicing clinicians, and patients. The platform applies evidence-based learning science to break complex medical concepts into what the company calls "microcontent" β modular learning units delivered online and via mobile, supplemented by a YouTube channel of educational videos.
The company was co-founded by Shiv Gaglani, who began the venture while a medical student at Johns Hopkins University and served as Co-Founder and CEO. Osmosis was acquired by the publisher Elsevier and became part of Elsevier's Global Medical Education portfolio, operating under the name "Osmosis from Elsevier." At the time of the acquisition announcement, the company reported reach in 195 countries, more than two million YouTube subscribers, over 150 institutional partnerships, and over a quarter of a billion content views. Around the acquisition period the organization described a global workforce of more than eighty-five educators, medical illustrators, video editors and related staff.
Note: several similarly named entities appear in public sources β a Cosmos-ecosystem DeFi protocol (osmosis.zone) and an AI reinforcement fine-tuning startup (osmosis.ai) β and are distinct from this company.
Founding story
Shiv Gaglani conceived Osmosis as a medical student at Johns Hopkins University, concluding that the century-old lecture-based approach to medical education could be made more personalized, dynamic and efficient. He took time off from the MD program to build the company, deferring medical school annually for about ten years while earning an MBA from Harvard in 2016. His first investors included his business school professors; Jeff Bussgang, who taught "Launching Technology Ventures" and is a managing director at Flybridge Capital, provided the company's first six-figure check.
Business model
Osmosis provides subscription-style access to a digital learning platform and video library for individual learners, and works with institutions β including medical schools and digital health companies β through partnerships. Following acquisition it operates as part of Elsevier's Global Medical Education portfolio.
Sources describe a learning platform serving subscribers and 150+ institutional partnerships, but do not disclose pricing or revenue figures.
Traction
At the acquisition announcement Osmosis reported reach in 195 countries, more than two million YouTube subscribers, over 150 institutional partnerships, and over 250 million content views. A podcast description around a year after the acquisition cited a global workforce of more than 85 educators, illustrators and video editors.
Latest developments
Osmosis operates as "Osmosis from Elsevier" within Elsevier's Global Medical Education portfolio. Elsevier stated it intends to apply Osmosis's microcontent approach to other segments of its healthcare portfolio, including nursing students and eventually patients. Co-founder and CEO Shiv Gaglani returned to Johns Hopkins to complete approximately a year and a half of remaining medical school while Elsevier accommodated a modified role.
βΈFull profile β market position, technology, go-to-market, geography, history, risks & controversies
Market position
Osmosis is positioned as a visual/short-form learning provider within digital health education. Elsevier framed the acquisition as complementing its existing digital medical education solutions and following its purchases of Shadow Health (virtual nursing simulations) and 3D4 Medical (Complete Anatomy 3D anatomy app).
Emphasis on highly visual, short-form microcontent grounded in learning science, combined with very large organic reach on YouTube and a broad international footprint.
Technology
The platform uses evidence-based learning science to create modular "microcontent" that converts complex medical concepts into short learning modules, delivered through web and mobile with content pushed to learners rather than relying on learners returning to the system. Earlier technology included a system that ingested users' uploaded lecture notes and generated related content recommendations.
Go-to-market
Distribution combines a large free-to-view YouTube channel that functions as a top-of-funnel audience channel, direct subscriptions, and institutional partnerships with medical schools and digital health companies. Post-acquisition, distribution is extended through Elsevier's global medical education channels.
Medical students, nursing and allied health students, residents, practicing clinicians, and β as an intended future segment under Elsevier β patients and their family members. Institutional customers include medical schools and digital health companies.
Geography
US-based with content reaching learners in 195 countries; parent company Elsevier is a global research publishing and information analytics firm.
History
Osmosis spent roughly its first two years building a technology platform that let users upload lecture notes and receive automatically generated content recommendations. Gaglani has said market demand proved to be concentrated in video content rather than that platform, prompting a pivot toward producing educational videos. The company subsequently scaled its video library and subscriber base, and was acquired by Elsevier, joining its Global Medical Education portfolio. After the acquisition, Elsevier accommodated Gaglani's return to Johns Hopkins to complete his clinical years of medical school.
Risks & controversies
No controversies are reported in the available sources. A notable research risk is name ambiguity: unrelated entities named Osmosis exist, including the osmosis.zone blockchain protocol and an osmosis.ai AI fine-tuning startup, which can contaminate automated data collection.
