Redwing Labs, the Bengaluru drone company that delivers vaccines and blood to villages a truck cannot reach in a day, says it has flown more than 300,000 kilometres beyond visual line of sight. For all that flying, the legal entity behind it booked operating revenue of just ₹1.17 crore in the year ended 31 March 2025, according to Registrar of Companies data compiled by TheCompanyCheck. That gap — enormous technical mileage, a tiny top line — is the whole story of Indian medical-drone logistics in one company.
It is a deep-tech venture that has raised a modest $3.62 million (about ₹34.8 crore; $1 ≈ ₹96.0 as of 18 September 2026, Trading Economics) across four rounds over roughly six years, as tracked independently by Tracxn and Crunchbase. It has run some of the most-cited public-health drone pilots in the country, in Arunachal Pradesh, Odisha and Karnataka, and in June 2025 it bought the assets of a Swedish drone startup to plant a flag in Europe. Whether any of that turns into a durable business is still an open question. This is what the public record shows, and where it stops.

What Redwing does
Redwing designs, builds and operates its own drone-delivery network rather than just selling hardware. Its core work is autonomous, beyond-visual-line-of-sight (BVLOS) logistics for healthcare, where the value of speed is highest.
- Sells an end-to-end service — order placement, flight operations and proof of delivery — not just drones (Tracxn, September 2026).
- Uses Made-in-India hybrid vertical take-off and landing (VTOL) drones, described at launch as ~50 km range and 2 kg payload, enough for 60–70 vaccine vials a trip (ITLN, February 2021).
- Primary customer is the public-health system: state governments and health-financing programmes that need vaccines, blood samples and medicines moved across terrain roads handle badly.
- Secondary lines the company lists are agricultural spraying and aerial mapping — the mapping business is why the registered entity is named Kitemaps Aerial Mapping Services (RoC, via Tofler).
- Typical deployment: a central hub near a district hospital running six to eight drones, serving community and primary health centres within about 30 km (SAMRIDH, 2024).
The origin
Redwing was founded in early 2018 by three college friends — Anshul Sharma, Arunabha Bhattacharya and Rishabh Gupta — who registered the company as Kitemaps Aerial Mapping Services Private Limited on 29 January 2018, RoC records show. The founding insight was narrow and physical rather than grand: hospitals and clinics in remote India lean heavily on refrigerators to store perishables such as blood and vaccines because resupply by road is slow and unreliable, and a lot of that stock expires unused. If you could move small, high-value medical payloads fast and on demand, you could shrink the cold-storage problem instead of just adding more fridges.
The team’s backgrounds sat in aerospace and defence-adjacent research: Seafund, an early backer, describes founder experience spanning NTU Singapore, India’s National Technical Research Organisation (NTRO) and global R&D programmes. That matters because BVLOS drone logistics is as much a regulatory and reliability problem as an engineering one — flying autonomously, out of sight, over people, in monsoon wind and hill country, is where most drone-delivery ideas die. Redwing chose to attack the hardest version of the problem first: public health in the geographies that need it most, where a customer with real urgency already exists.
The struggle years
The early record is one of a deep-tech company living pilot to pilot, with the timeline shaped less by product releases than by what regulators would allow. When Redwing raised its first institutional money in February 2021, commercial BVLOS flight simply was not permitted in India; the company could fly only within visual line of sight, and was one of 20 DGCA-approved consortia running trials to prove the concept, as reported by ITLN. A logistics business that is legally barred from its core flight mode is, for a stretch, not yet a business.
Revenue reflects that lumpiness. The registered entity’s top line is small and volatile: RoC data via Tofler shows total revenue grew 177.6% in the year to 31 March 2024, and then TheCompanyCheck records revenue falling to ₹1.17 crore for the year to 31 March 2025 — a decline of roughly 68% year on year on the same source’s reading. That is the financial signature of grant- and pilot-funded work: money arrives in bursts tied to specific programmes, then drops when a pilot ends and the next contract has not yet started. Paid-up capital remains tiny at ₹1.80 lakh against authorised capital of ₹15.00 lakh (Tofler), consistent with a company that has stayed lean and raised comparatively little equity.
The turning point
The event that turned Redwing from a trial participant into a named operator was the Arunachal Pradesh healthcare pilot. In August 2022, working with the Government of Arunachal Pradesh, the World Economic Forum’s “Medicines From the Sky” initiative, and the USAID-supported SAMRIDH facility implemented by IPE Global, Redwing began running an end-to-end drone healthcare network out of Seppa in East Kameng district (eHealth/Elets and BioSpectrum India, August 2022). This was no longer a demo — it was routine delivery of vaccines, essential drugs and diagnostic samples to community and primary health centres.
The numbers on either side of that shift are stark. Road logistics in that terrain can take the better part of a day; the drone network delivered medical supplies “up to eight times faster than road-based logistics” and covered 30 km in about 30 minutes (BioSpectrum India; SAMRIDH). By SAMRIDH’s later account, the deployments across Arunachal Pradesh and Odisha had logged 1,100-plus flights, collected 1,400-plus diagnostic samples and delivered more than 42,000 medicine SKUs. That real-world dataset — flying safely in hills, coastal winds and adverse weather — is what the company would later point to when it claimed more than 300,000 km of BVLOS flight experience (company-stated, via The Machine Maker, June 2025).
The money behind it
Redwing has stayed deliberately capital-light for a hardware company. The funding shape, per Tracxn and Crunchbase:
- Total raised: $3.62 million across four rounds since 2019 (Tracxn, corroborated by Crunchbase, September 2026).
- Pre-seed: from US accelerator Techstars, which put Redwing through its programme (YourStory profile).
- Seed, February 2021 — $1 million: led by ITI Growth Opportunities Fund, with Asymmetry Ventures, Beyond Capital Fund, Cloud Capital and LetsVenture, plus angels linked to the Bill & Melinda Gates Foundation, Google and Microsoft (ITLN, 17 February 2021).
- Later rounds: Tracxn lists additional seed-stage rounds through 2023–2024 with amounts undisclosed; deep-tech fund Seafund is among the backers documenting its Redwing thesis (Seafund, August 2025).
- Board signal: ITI’s Mohit Mahendra Gulati sits on the board as a nominee director (RoC, via Tofler), the clearest sign of who holds sway among investors.
What each backer changed: Techstars gave the founders their first structured capital and network; ITI Growth Opportunities anchored the 2021 seed and took a board seat; Seafund brought a deep-tech investor willing to underwrite the long regulatory runway. Notably, there is no publicly disclosed valuation — a reminder that this is an early-stage company, not a late-stage one.
How it makes money
Redwing earns as a drone-logistics operator, and the economics are unusual because much of the demand is public health rather than pure commerce.
- Money in: contracts and programme funding to run delivery networks — state-government health projects and blended-finance facilities such as SAMRIDH (USAID/IPE Global), plus B2B logistics and pharma partnerships.
- What people get wrong: Redwing is not primarily a drone manufacturer selling units. Its revenue is service revenue from operating flights and networks — order-to-doorstep delivery, billed to the institution that needs the payload moved.
- Costs out: drone hardware and maintenance, ground hubs (six to eight drones each), trained pilots and operations staff, insurance, and the regulatory/compliance overhead that BVLOS flight demands.
- Where margin can sit: Tofler’s reading of FY24 RoC data shows a net profit margin of 15.9% — plausible when a funded pilot is running at scale, but the sharp FY25 revenue drop shows how fragile that is between contracts.
- Adjacent revenue: agri-spraying (drones covering up to 6 acres per hour, per Seafund) and mapping, which diversify away from grant cycles.
The numbers
Redwing is an early-stage private company, so audited line-item detail is limited; the figures below are from Registrar of Companies filings surfaced by Tofler and TheCompanyCheck. Amounts in ₹ crore unless stated.
| Financial year (ended 31 Mar) | Operating revenue (₹ crore) | Profitability / growth |
| FY23 | Not separately disclosed in public filings (base year off which FY24 grew) | — |
| FY24 | Within the ₹1–100 crore band (Tofler) | Total revenue up 177.6% YoY; net profit margin 15.9%; net worth up 262.1% (Tofler/RoC) |
| FY25 | ₹1.17 crore (TheCompanyCheck/RoC) | Revenue down ~68% YoY on the same source’s reading; FY25 profit/loss not separately disclosed |
The honest read: revenue is small and pilot-driven, and the year-to-year swings — up 177.6% into FY24, then down about 68% into FY25 — say more about contract timing than about any collapse or breakout. Headcount was reported at 26 employees as of 31 August 2025 (Tracxn), which is a lean team for the flight mileage claimed.
Where the money comes from
The revenue mix is concentrated by sector and geography, which is both the strength and the fragility of the model.
- By sector: healthcare logistics is the flagship — vaccines, blood, diagnostics and medicines — with agri-spraying and mapping as secondary lines.
- By geography (India): the documented public deployments are concentrated in Arunachal Pradesh, Odisha and Karnataka (Seafund; SAMRIDH). In Odisha’s Kandhamal district, Redwing worked with ITI-Phulbani from June 2023 to train local youth on drone operations, tying the network to local employment (YourStory).
- By funder type: a large share of demand traces to public-health and blended-finance programmes (state governments, USAID-backed SAMRIDH, WEF’s Medicines From the Sky) rather than to open-market commercial buyers.
- The surprise — a European pivot: in June 2025 Redwing acquired the assets of Swedish drone-delivery startup Aerit, including its autonomous flight system “Stewie”, to enter Europe (Business Standard/ANI and The Machine Maker, June 2025). Aerit had worked with Foodora in 2024 and, per the announcement, held EASA SAIL II permits and claimed to be first to complete commercial food deliveries by drone in Sweden. For a company whose Indian revenue sits near ₹1 crore, buying its way into European regulatory access and food delivery is a notable bet.
The risks
- Regulatory dependence: the entire model rests on BVLOS permissions. Redwing spent its early years unable to fly commercially beyond visual line of sight (ITLN, 2021); any tightening of DGCA or EASA rules, or a high-profile safety incident in the sector, directly throttles operations. The mechanism is simple — no permits, no flights, no revenue.
- Revenue concentration and lumpiness: demand is heavily tied to grant- and government-funded health programmes. The ~68% revenue drop into FY25 (TheCompanyCheck/RoC) shows how a business built on pilots swings when one programme ends before the next begins.
- Capital and scale mismatch: at $3.62 million total raised (Tracxn) and 26 staff (Tracxn, August 2025), Redwing is competing in a field the industry itself sizes in billions — Seafund cites India’s drone sector growing from about $3 billion in 2022 toward $13 billion by 2030. Global peers named alongside it include far better-funded firms such as Zipline. Scaling networks and now integrating a European acquisition on a thin balance sheet is the central execution risk.
The takeaway
Redwing’s real lesson is about sequencing, not drones. Faced with a market that did not legally exist yet, the founders did not wait for rules or chase the biggest commercial prize; they went to the places where the value of a fast delivery was most obvious and least contested — remote health centres — and let public-health programmes fund the flying hours that built their safety record. That record, more than 300,000 claimed BVLOS kilometres, became the asset. It is what let a company earning near ₹1 crore a year credibly buy a European operator and talk about a global network. The transferable idea: in a regulated, capital-hungry frontier, the winning move can be to accumulate hard-to-fake operational proof in the niche nobody contests, and treat that proof — not revenue, not yet — as the thing you are really building.
