Urban Sky develops high-altitude balloons (Microballoon™/mHAB), custom stratospheric payloads, control software, and AI-derived forecasting and autonomous flight control systems. Its flagship mHAB product is a rapidly deployable, navigable stratospheric balloon that can operate above 60,000 feet for multiple days. The company serves commercial, civil government, and U.S. defense customers, including NASA, the oil & gas sector, wildfire monitoring organizations, the U.S. Army, and the U.S. Air Force. Urban Sky demonstrated its Hot Spot LWIR imaging system with NASA and the Air Force, producing wildfire heat maps the company says are 100x finer than publicly available MODIS and VIIRS data. The firm plans to develop and commercialize a connected suite of products and to pioneer technologies to deploy a global constellation of long-duration, persistent stratospheric balloons for search & rescue, environmental monitoring, disaster response, communications, and intelligence support. Financially, Urban Sky closed a $30M Series B to accelerate development and commercialization of its technology and product portfolio. Urban Sky builds small, reusable stratospheric balloons—branded Microballoons—that are deployed from a pickup truck to collect high-resolution Earth imagery and data products. The company offers natural color optical images today and is developing near-infrared and long-wave infrared sensors (the latter, HotSpot, has been demonstrated to monitor wildfires in real time under a NASA grant with Air Force support). Urban Sky uses a patented termination and descent mechanism to recover balloons and a stratospheric flight simulator to back-predict launch sites, lowering operational costs. The 14-person startup has been running tasking missions in the Rocky Mountain region and has brought in millions in revenue. It plans to scale operations by building a routine catalogue of refreshed data over highly populated areas and other customer areas of interest. Urban Sky aims to drive down imagery costs—reporting roughly $5–$10 per square kilometer at 10 cm resolution—and compete on cost and revisit cadence with traditional satellite providers. Urban Sky is a Denver, CO startup focused on stratospheric technology and remote sensing. The company develops the Microballoon, leveraging component miniaturization and first-of-its-kind balloon reusability to operate in the stratosphere. Its approach uses the high vantage point of the stratosphere to reduce the cost of high-resolution remote sensing and weather-related data capture over broad areas. Urban Sky says this enables more impactful data collection across larger regions than traditional platforms. The company announced an over-subscribed $4.1 million Seed financing round. Investors in the round include Catapult Ventures, Union Labs, TenOneTen Ventures, New Stack Ventures, and Techstars.
