Private healthcare company investor Malin has bought a 38% shareholding in 3D4Medical for $16.4m.
Based in Ireland, 3D4Medical specialises in the development of medical, educational and health and fitness apps for healthcare professionals as well as student and patient education.
The company's apps, including its "Essential Anatomy" app, have been downloaded more than 9 million times globally.
As part of today's deal, Malin has also agreed a call option to increase its shareholding to 50% on a fully diluted basis.
Malin will also appoint three directors to the board of the company, including John Herlihy, the former head of Google Ireland, and former Elan CEO Kelly Martin.
3D4Medical recorded EBITDA of $700,000 on revenues of $4.1m for the year to the end of December.
Malin's chief executive Adrian Howd said the company sees "significant opportunity" for growth through the deal as the 3D4Medical offers Malin a unique asset at the intersection of the technology and healthcare sectors.
"The mobile healthcare sector is clearly part of the future and we are pleased to add such a quality asset to our overall life sciences focus," he added.
