IndiGo Takes Equity Stake in Sarla Aviation: A ₹10 Crore Bet on India’s Electric Flying Taxi Future
In a move that signals the coming of age of India’s urban air mobility sector, the country’s largest airline has placed a strategic bet on the future of electric aviation. IndiGo, through its investment arm IndiGo Ventures, has acquired an equity stake in Bengaluru-based Sarla Aviation, a startup developing electric vertical takeoff and landing (eVTOL) aircraft .
The investment, valued at ₹10 crore, was made in January 2026 and filed with the Registrar of Companies on April 15, 2026 . It represents IndiGo’s first direct equity investment in the eVTOL space, following the collapse of its earlier non-binding partnership with US-based Archer Aviation .
“IndiGo didn’t lose appetite for the space. Archer couldn’t deliver on the timelines they committed to.”

The deal values Sarla Aviation at the same valuation as its January 2025 Series A round, which was led by Accel and included participation from angel investors Binny Bansal (Flipkart co-founder), Nikhil Kamath (Zerodha co-founder), and Sriharsha Majety (Swiggy co-founder) .
The Contenders: A Global Trend Takes Flight
IndiGo’s investment is part of a broader global pattern where major airlines are backing eVTOL startups to secure a foothold in the emerging urban air mobility market.
| Airline | eVTOL Partner | Investment Type |
|---|---|---|
| IndiGo | Sarla Aviation | Equity stake (₹10 crore) |
| Delta Air Lines | Joby Aviation | Strategic partnership & investment |
| United Airlines | Archer Aviation | Strategic investment |
The collapse of IndiGo’s partnership with Archer—which was announced in November 2023 with ambitious plans to launch flying taxis in Delhi, Mumbai, and Bengaluru by 2026—paved the way for the airline to turn its attention to a homegrown alternative .
Shunya: The Six-Seater Electric Air Taxi
Sarla Aviation was founded in October 2023 by Adrian Schmidt, Rakesh Gaonkar, and Shivam Chauhan—engineers with prior experience at German eVTOL firm Lilium . The company is named after Sarla Thakral, India’s first female pilot, who earned her aviation license in 1936 at the age of 21 .
The startup’s flagship aircraft, Shunya (Sanskrit for “zero”—symbolising zero emissions and zero congestion), is a six-passenger eVTOL designed specifically for urban environments .
Shunya Specifications:
| Specification | Details |
|---|---|
| Seating Capacity | 6 passengers + pilot |
| Maximum Payload | 680 kg |
| Top Speed | 250 km/h |
| Range | Optimised for 20–30 km urban trips (up to 160 km with future batteries) |
| Launch Target | 2028 (Bengaluru) |
The aircraft is designed to use existing helicopter landing pads (helipads) at hotels, hospitals, and tech parks, minimising the need for new infrastructure . The company aims to price rides similarly to premium ride-hailing services like BluSmart, Ola SUV, or UberXL—with a long-term goal of eventually reducing costs to that of an auto-rickshaw .
Technical Progress: From Prototype to Ground Testing
Sarla Aviation has made significant technical progress since its founding. In January 2025, the company unveiled a full-scale static prototype of Shunya at the Bharat Mobility Global Expo in New Delhi .
In December 2025, the company achieved a critical milestone: the commencement of ground testing for its half-scale eVTOL demonstrator, SYLLA SYL-X1, at its Bengaluru facility .
SYL-X1 Specifications:
| Specification | Details |
|---|---|
| Wingspan | 7.5 metres |
| Scale | Half-scale demonstrator |
| Development Time | ~9 months |
| Purpose | Validation of structural integrity, propulsion, safety systems |
The company claims SYL-X1 is the “largest and most advanced private eVTOL demonstrator of its kind currently under development in India” . The aircraft was developed in approximately nine months and is built with certification intent from the outset, forming a direct bridge toward the full-scale 15-metre wingspan Shunya .
The Manufacturing Vision: A ₹1,300 Crore ‘Sky Factory’
Beyond aircraft development, Sarla Aviation has ambitious manufacturing plans. In November 2025, the company announced a ₹1,300 crore investment to establish a 500-acre aerospace manufacturing facility in Andhra Pradesh .
Proposed Facility Specifications:
| Feature | Details |
|---|---|
| Location | Anantapur, Andhra Pradesh |
| Land Area | 500 acres |
| Investment | ₹1,300 crore (initial) |
| Production Capacity | Up to 1,000 aircraft annually |
| Key Features | Composites lines, powertrain systems, wind tunnel, 2 km runway, VTOL testing pads, R&D labs, pilot training, MRO facilities |
The facility is being designed as India’s “first fully integrated ecosystem for eVTOL manufacturing, flight testing, certification, training and maintenance” . It will also feature renewable energy systems, water recycling processes, and circular economy practices—aligning with the company’s sustainability focus.
The company is working with the Andhra Pradesh government to co-develop certification infrastructure and dedicated Urban Air Mobility (UAM) corridors, with the goal of enabling commercial air taxi services across South Indian cities by 2029 .
The Competitive Landscape: India’s eVTOL Race
Sarla Aviation is not alone in its pursuit of India’s urban air mobility market. Several other players are vying for a share of this emerging sector:
| Company | Focus | Status |
|---|---|---|
| Sarla Aviation | 6-passenger eVTOL | Ground testing; target launch 2028 |
| ePlane | eVTOL development | Competing player |
| BluJ Aerospace | eVTOL development | Competing player |
| JetSetGo | Air taxi operator | Plans to operate eVTOLs |
IndiGo’s parent company, InterGlobe Enterprises, had previously partnered with Archer Aviation, but that non-binding agreement has since fallen through . The airline’s pivot to Sarla Aviation signals a continued commitment to the sector, now directed toward a homegrown solution.
As Sarla Aviation CEO Adrian Schmidt told Financial Express in January 2025: “Out of all the mobility options that we have in India right now that can enable us to become a global superpower, flying taxis are the only solution that can get us there in the next 10-15 years” .
What This Means for India’s Startup Ecosystem
IndiGo’s investment in Sarla Aviation carries several important signals for India’s startup landscape:
1. Corporate-Startup Collaboration Is Maturing
The investment represents a strategic partnership between India’s largest airline and a deep-tech startup—not just a financial transaction. This model of corporate validation can accelerate startup growth and provide credibility with other investors.
2. Deep-Tech Hardware Is Attracting Strategic Capital
Unlike software startups that can scale with relatively little capital, eVTOL development requires significant investment in R&D, testing, and manufacturing. IndiGo’s backing signals that strategic investors are willing to support capital-intensive deep-tech ventures.
3. India Is Competing in Frontier Aviation Technology
With Sarla Aviation’s ground testing milestone and manufacturing plans, India is positioning itself among a small group of nations actively developing next-generation vertical flight systems at an industrial scale .
4. The Urban Air Mobility Market Is Real
While sceptics may question the timeline for flying taxis, the involvement of major airlines—IndiGo, Delta, United—suggests that industry insiders see commercial viability within the next decade .
The Road Ahead: From Bengaluru to the World
Sarla Aviation has set an ambitious roadmap. The immediate priorities include:
- 2026: Continue ground and flight testing of the SYL-X1 demonstrator
- 2027-2028: Full-scale Shunya prototype testing and certification
- 2028: Commercial launch in Bengaluru, connecting airports, tech parks, hospitals, and hotels
- 2029-2030: Expansion to Delhi, Mumbai, Pune, and other major cities
The company has raised $13.4 million across five rounds to date . With IndiGo’s strategic backing, a growing team (currently ~70 employees), and a clear manufacturing roadmap, Sarla Aviation is well-positioned to be a leader in India’s electric aviation revolution.
As co-founder and CTO Rakesh Gaonkar stated: “Our focus has never been on being first, but on building to last and on creating an aviation giant. We are building a platform that can be certified, produced, and safely operated, designed and owned entirely in India” .
The Final Word
IndiGo’s ₹10 crore equity stake in Sarla Aviation is more than just an investment—it is a statement of intent. India’s largest airline is betting that the future of urban mobility will be electric, vertical, and shared. And it is putting its capital behind a homegrown startup to make that future a reality.
With the Shunya eVTOL targeting a 2028 launch in Bengaluru, a ₹1,300 crore manufacturing facility planned in Andhra Pradesh, and ground testing already underway, Sarla Aviation is moving from concept to reality. The journey from prototype to commercial certification is long and fraught with technical and regulatory challenges. But with IndiGo’s backing, a world-class team, and a clear vision, Sarla Aviation is well-positioned to be a pioneer in India’s urban air mobility revolution.
As CEO Adrian Schmidt noted: “Flying taxis are effectively an uncongestible mobility solution. You will never be stuck in traffic if you bring mobility into the air” . For India’s congested cities, that promise is worth the wait.
