How Red Balloon Aerospace Is Building India’s Near-Space Economy
Before a payload reaches orbit, it often needs to be tested in near-space conditions. Yet access to such facilities remains limited in India, with the few available ones heavily oversubscribed and long waitlists that stretch development timelines.
CVS Kiran, who spent years designing space vehicles intended to reach orbit, recognised this gap. A former scientist at the Vikram Sarabhai Space Centre and former Vice President at Skyroot Aerospace, he saw an opportunity in the largely unused domain between aviation and satellites.
“Between where aircraft end, and satellites begin lies an entire domain that’s largely unused, close enough to be affordable, and high enough to be persistent,” Kiran says.
That insight led him to co-found Red Balloon Aerospace in 2025. Based in Vijayawada, Andhra Pradesh, the spacetech startup is developing platforms for what it calls the near-space infrastructure layer, using stratospheric airships, aerostats, and super-pressure balloons.
“Red Balloon Aerospace exists to ensure that India owns, operates, and leads in the near-space domain, through indigenous platforms, deeptech engineering, and a long-term vision for near-space as national infrastructure,” Kiran, the company’s CEO
Building the Platform Family
The startup’s primary platform is HELIX, an autonomous stratospheric airship designed for persistent, long-endurance near-space operations.
On May 27, Red Balloon Aerospace launched VISTA, its super-pressure balloon, from the Indira Gandhi Stadium in Vijayawada. The mission tested core subsystems that will also be used in HELIX and placed India among only five countries—alongside the United States, France, Japan, and China—with indigenous super-pressure stratospheric balloon capabilities.
The company is also preparing to fly ALTIS, its tethered aerostat, which will serve as another testbed for systems feeding into HELIX.
Red Balloon designs its envelope film—an ultra-thin, flexible polymer used for the gas-retention skin of high-altitude balloons—and reinforcing structure entirely in-house. “We own our envelope film and reinforcing structure design, end-to-end in-house, which let us go from starting operations in November to first flight in under a year,” Kiran says.
VISTA, ALTIS, and HELIX are being developed as a modular platform family. The company is building materials, avionics, navigation systems, payload interfaces, communication systems, and mission software as reusable building blocks across these platforms.
Applications and Business Model
The platforms target applications including communications and V2X, disaster response, remote connectivity, and domain awareness.
Red Balloon serves both business-to-business (B2B) and business-to-government (B2G) clients. For commercial customers, it offers a rideshare model in which multiple payloads share a single mission. “Commercially, partners come to us today for various applications through our rideshare model, where a single mission carries multiple payloads at once,” Kiran explains.
Government applications could include sovereign connectivity, Earth observation, and disaster response. The startup has already secured international B2B clients expected to fly payloads soon.
It currently operates from its own facility at its headquarters and plans to expand into a larger site.
Establishing Near-Space as a Distinct Category
India’s private space industry has entered a broader participation phase, Kiran notes, but near-space still needs recognition as its own category.
Near-space begins in the stratosphere, roughly between 20 km and 50 km above Earth, far below geostationary orbit at 35,786 km. In this altitude band, platforms can operate where conventional aircraft and satellites face different limitations.
“What is still ahead of us is building clear recognition of near-space as its own category, distinct from satellites and aviation, so policy and investment conversations engage with it directly,” Kiran says. He believes India has the engineering talent, capital, and government support to compete globally once the category gains wider recognition.
Red Balloon’s team brings more than seven decades of combined experience in lighter-than-air technology and stratospheric platforms. The company continues to add subject-matter experts as its mission cadence increases.
Funding and Competitive Position
The startup raised an undisclosed pre-seed round in early 2026 and is currently raising a seed round, with details yet to be finalised.
It competes with international players such as Tucson-based World View and Moriarty-based Sceye. Kiran points to Red Balloon’s full control over its technology stack as a key advantage: “We own our full value chain, from envelope film and reinforcing load-bearing members to the systems that process what our platforms capture. That ownership, combined with how fast we move and the infrastructure we have already built, puts us years ahead of anyone else in India.”
For now, the company remains focused on building flight heritage across VISTA, ALTIS, and HELIX while developing the infrastructure and technology it believes can establish near-space as a new category for India’s private space industry.
