The funding will be used to develop and commercialize a connected suite of products that will unlock the full value of the tactical stratosphere for military and commercial customers.

The funding round was led by Altos Ventures, with participation from New Legacy Ventures, Lerer Hippeau, Catapult Ventures, Lavrock Ventures, New Stack Ventures, TenOneTen, DA Ventures (a Denver Angels Affiliate), Union Labs VC, and Techstars.

Urban Sky's products enable routine and easy access to the stratosphere and the value locked within it. The company's hallmark product - the stratospheric Microballoon™ (mHAB) - offers quick, easy, long-duration, and controllable flight in the stratosphere. And the stratosphere itself offers everything space cannot - rapid access, navigation, extended loitering, and affordability.
