Bharti Airtel's impossible survival story | Intermission E03

ELI5/TLDR

Airtel is India’s most resilient telecom company. Sunil Mittal built it from a bicycle parts factory into a global operator that has survived every catastrophe the Indian telecom industry could throw at it—brutal regulators, technological upheaval, Reliance entering twice, and still emerged dominant. This 4-hour documentary traces 30 years of survival by adapting faster than rivals, outsmarting regulation, and always having someone brilliant enough to stare down the next crisis. Today, Airtel is the third most valuable Indian company, and Mittal is thinking in decades, not quarters.

The Full Story

Ludhana: The Spirit That Forged Sunil Mittal

The story doesn’t begin with telecom. It begins with Ludhana, a city on the Grand Trunk Road—a trade artery connecting Kabul, Islamabad, Delhi, and Dhaka since the 3rd century BC. After Partition in 1947, Ludhana absorbed a wave of Hindu and Sikh refugees fleeing Pakistan with nothing but trunks. The city’s culture crystallized around what locals call the jugard philosophy: mastering the art of replicating and improving Western machinery with minimal resources. No permits, no gatekeeping, no excuses. By the 1960s-70s, Ludhana had become India’s hub for bicycles, sewing machines, auto components, and diesel engines. Everyone understood working capital, net profit, and risk from childhood.

Satpal Mittal, born 1931, chose politics over business. His son Sunil—born 1957—had other ideas. At 19, in 1976, Sunil borrowed 20,000 rupees from his father to start a bicycle components factory. When cash ran short, he borrowed 5,000 from Bridgemond Munjal of Hero Cycles, who warned him: don’t make a habit of it. Sunil didn’t. He pivoted to yarn, then cold-rolled steel. By 1980, he and his brothers set up Bharti Overseas Trading Company. When Japan’s Suzuki sent a representative to meet him (still just 23), Sunil landed a generator business that roared—until the Indian government suddenly banned imports and handed licenses to bigger houses instead. The pattern became clear: find a market the big houses don’t care about yet, prove it exists, then get muscled out by regulation and bureaucracy. Test yourself. Learn. Move on.

The License Raj and the Telecom Gamble (1991-1994)

By 1991, India’s Department of Telecommunications issued its first ad for mobile telephone licenses. Two parts: technical muscle and financial muscle. Applicants didn’t need much money upfront—just proof of backing from international partners. Sunil was in Goa when he read the ad. He left his factories to his brothers and flew to London for 60 days, paying specialists to teach him telecom. By his own account, he spent a crore or more—20% of his profits—not to buy a license, but to educate himself. Best investment of his lifetime, he later said.

Back in Delhi, he set up shop in a Nehru Place building with Analjit Singh of Max Group in the same complex. Both hungry young entrepreneurs. Both civil. The government wanted each license bid to include a foreign partner, so Sunil found SFR, a French telecom company. Michael Villino, the SFR executive, gave him a Saturday half-hour meeting expecting nothing. Sunil’s impatience worked: he drafted a memorandum of understanding on the spot with no legal background. Villino was alarmed but impressed. He signed. When Rajiv Chandrasekhar’s BPL threatened to steal SFR away, Sunil called Villino, pleaded with him to trust his gut. Villino honored his word.

The bidding process descended into chaos. The government’s grading system totaled 95 points instead of 100—they’d dropped a criterion and forgot to redo the math. Tata Group, bidding with a thin file, got nothing and went to court. Tata would lose its 3-year legal fight. Sunil, with cartons of paperwork, won one circle: Delhi. That’s how Bharti Cellular began.

The Outsourcing Revolution and Akil Gupta (1995-2006)

In early 1995, Sunil needed a CFO. He’d met a chartered accountant named Akil Gupta at a Diwali party in 1980—they bonded over risk-taking at a card game. Over dinner at Oro in Delhi, Sunil asked Akil: “Do you want to become an entrepreneur?” Akil said yes. Akil would become the fourth Mittal brother.

By 2002, Airtel had gone public and was trying to expand nationwide. Sunil and Akil faced a problem: building and managing a pan-India telecom network required engineering talent no one had. Outsourcing from India was virtually unheard of. But Airtel didn’t have the money to hire all the engineers it needed. They were constrained, so they got creative.

Sunil placed his first equipment order with Ericsson for $27 million. He told Curt Hellstrom, the Ericsson president, over lunch: “I don’t have the money to pay you.” (He didn’t even have money for the lunch—an executive with a credit card covered it.) Sunil offered 15% upfront and asked when he could pay the remaining 85%. Sunil’s answer was instructive: “I will pay you on happiness.” When asked to define happiness, he said: “Happiness is when people are making calls on the street and they are happy.”

Akil, the chartered accountant, did something remarkable. He deciphered the Erlang—a unit of radio wave capacity—and proposed paying Ericsson per Erlang of capacity used, not per equipment sold. This flipped the incentive structure. Before, Ericsson made more money by selling more boxes; now, both sides shared the goal of maximizing customer usage. For the first time in telecom history perhaps anywhere, the equipment vendor and operator sat on the same side of the table.

This created an epoch-making insight: Akil realized Airtel didn’t need to own everything. It needed to own the customer relationship and the brand. Everything else—towers, fiber, IT systems—could be managed by specialists. In 2006, after failed talks in 2001 and 2005, Airtel and Hutchison Max and IDEA agreed to create India’s first tower-sharing company, Indus Towers. Instead of building separate towers, they’d pool 22,000 towers and share costs. When a third tenant joined, costs dropped for everyone. The model became self-reinforcing.

“The construct of tower sharing is such that every time a new tenant comes in, both the tenant and the new tenant benefit through lower rental costs. A company makes more money when it charges its existing customers less, not more.”

This tower model, born from Indian constraints, became a world first and a permanent feature of global telecom.

The Reliance Disruptor and the Pivot to Consumer (2002-2008)

In December 2002, just months after Airtel’s IPO, Mukesh Ambani launched Reliance Infocom. It was CDMA-based wireless local loop—technically a fixed-line license, not mobile. But Reliance had built a 60,000 km fiber-optic backbone (a $2 billion investment, largest in telecom history) that stitched its circles together. A Reliance subscriber in Maharashtra could roam to Delhi and keep using the same network. Regulators hadn’t foreseen this interpretation.

Reliance’s offer was devastating: 400 minutes free outgoing, unlimited free incoming, 600 rupees per month. By 2003, the Monsoon Hungama offer: a free CDMA phone for 51 rupees. Voice calls became free to Reliance users (who just gave missed calls to friends). Airtel’s stock crashed from 45 rupees (IPO) to 20 rupees.

Sunil’s quote during this time, from a Times of India article he wrote himself (rare honesty from a CEO): “I felt that if we stood up at this time the storm would just blow us away… I said, lie low, and we will live to fight another day.”

The regulatory response was typical of Indian chaos: the government introduced a unified access license and forced everyone to switch to revenue-share models instead of fixed license fees. Reliance was “normalized.” But the real lesson Sunil learned was different. Airtel had been a premium, high-margin, low-volume company. It now realized India was a high-volume, low-margin market. Scale was the ultimate advantage.

Airtel hired Gopal Vittal from Hindustan Unilever, the FMCG company that had mastered distribution, bundling, discounting, and rural reach. Gopal brought the prepaid recharge model from Hutchison Max and launched it under the brand Magic in Delhi. He consolidated Airtel’s chaotic tariff plans into simple offerings. By end of 2003, Airtel’s stock surged to 80 rupees.

“We were used so used to a wartime style of working that we created our own fires. We still have some pockets that don’t like calm. So they create fires and then try to douse them.”

Africa: The Expensive Dream That Nearly Broke Airtel (2008-2016)

Sunil’s global ambition was boundless. He looked at Africa and saw a young continent of 1 billion people, majority below 30, with high mobile penetration potential. He bought Zain, a 15-country African operator, for $10.7 billion—the largest acquisition by any Indian company at the time. The deal included $1.7 billion of Zain’s debt and came when Airtel itself was drowning.

The African playbook didn’t work. Each country had different regulations, taxation, labor protectionism. Airtel couldn’t outsource or offshore; governments and workers protested. No middle-class market like India. Price elasticity was different—when Airtel cut rates in India, volumes surged; in Africa, consumers just bought salt with the saved money. Airtel had paid $10.7 billion for an asset that, by 2016, was valued at $3.9 billion.

The turnaround came through cloud-based customer value management software that unified all 15 countries under one billing engine, even without a common tower infrastructure. Aggressive pruning followed. Airtel Africa IPO’d in 2019 at $3.9 billion. By focusing on digital money transfer (Airtel Money), Airtel Africa carved out a multi-billion-dollar business. Sunil’s bet eventually paid, but it taught him that global expansion requires surgical execution, not cargo-cult replication of the India model.

Gopal Vittal’s Ascendancy and the Jio War (2013-2021)

By 2012, Airtel was in crisis. Twelve straight quarters of profit decline. Sanjay Kapoor’s regime had fractured the company into silos. Sunil reached back to HUL and brought Gopal Vittal back as “Group Director Special Projects.” He sent Gopal to Singapore, Australia, and Japan to study how 4G and data-driven operators worked. In January 2013, Gopal became CEO.

His first three years were ruthless simplification. He decimated the old leadership. He brought in international talent: Sini Gopalan from Vodafone UK as consumer chief. He reversed some of Akil Gupta’s outsourcing deals, starting to insource critical capabilities (APIs, radio planning, backend architecture). He launched Airtel’s 4G network in August 2015—before Reliance Jio’s commercial launch—across 300 cities.

Then Jio arrived.

In September 2016, Mukesh Ambani announced: “The era of paying for voice ends today. No Jio customer will ever have to pay for voice calls again.” Jio had bet on LTE, built a network from scratch with 250,000 km of fiber, leased 1 million towers, and offered everything free: voice, SMS, 4G data. By month seven, it had 100 million subscribers. By 18 months, 200 million. Jio signed up more subscribers in 170 days than most operators would in a decade.

Airtel’s revenue came 65-75% from voice. In a single stroke, that market evaporated. Airtel’s EBITDA margin crashed from 40% to 24%. Stock prices tanked. Industry watchers gave Airtel a 30% chance of surviving.

Sunil’s response was total war. He prepared “like it was preparing for war.” War rooms tracked dual-SIM users in real-time. Airtel detected when a customer added a Jio SIM and immediately sent aggressive retention offers. It fought for premium customers territory by territory (Karnataka, Delhi, Punjab). It upgraded its own network to 4G in parallel to Jio’s launch.

But Gopal’s boldest move was counterintuitive: in November 2018, he introduced minimum RPU (minimum revenue per user). Every subscriber had to recharge at least once every 15 days. Those who didn’t couldn’t even receive calls. Airtel went from 333 million to 284 million subscribers—shedding 49 million low-value users.

Why was this genius? Because those 49 million users were on 2G, consuming capacity Airtel now needed for 4G customers. By purging them, Airtel freed spectrum and tower capacity. It also had to only satisfy those 284 million paying customers. Meanwhile, Jio’s network got strained by free users. Airtel’s network quality improved; Jio’s degraded under load.

Then Airtel introduced Airtel Family, bundling mobile, DTH, broadband, and financial services into one bill. The strategy flipped: instead of three family members each switching individual SIMs to Jio, Airtel made switching harder by tying them together.

The result, by Q4 FY2026: Jio leads on subscribers (490M vs. 474M), but Airtel leads on ARPU (average revenue per user): 257 rupees vs. 214. Airtel makes more money from fewer, premium customers. The Jio dream of being a digital services powerhouse (JioHotstar, JioMusic) and capturing B2B never fully landed. Airtel, which was always strong in B2B, captured market share from Vodafone Idea’s collapse.

“When this sector started collapsing it was like taking candy from a kid. Bharti just did it best—this was both on the consumer side as well as on the enterprise side.”

The Three-Body Problem and Sunil Mittal’s Fourth Body

The documentary frames Airtel’s existence as a physics problem: Sunil Mittal sits at the center, orbited by three gravitational forces. The first body is regulation and regulators—constant rule changes that sometimes hurt, sometimes help. The second is technology (2G → 2.5G → 3G → 4G → 5G, and spectrum complexities). The third is competition (8 operators in 1994 → 14-15 by 2010 → 2.75 today). Like the three-body problem in physics, these orbits are chaotic and nearly impossible to predict.

But there is a fourth body at the center: Sunil Mittal himself.

What makes Sunil Mittal exceptional: he never confuses surviving with winning. At lunch with Ericsson’s Hellstrom, not having money for the bill. Convincing SFR to stay when BPL threatened to steal them. Holding the outsourcing bet against board resistance. Bringing Gopal back after Gopal had left. And most recently, understanding that Jio coming in a second time meant pivoting willingly back to premium positioning—not because forced to by regulation, but because Sunil chose it.

The culture he built is described as: HUL talent + founder-driven. It’s why competitors can’t replicate Airtel. Reliance has Jio but is state-like in centralization. The Tatas have deep governance but aren’t founder-obsessive. Airtel has both: discipline of professionals + hunger of Sunil.

A 15-year Airtel veteran said: “It’s collective accountability. We supported each other. We had common goals. We had freedom and we had autonomy.” But that freedom came with teeth: if you committed to an outcome, you were held to it.

Another culture marker: the “reverse Monday syndrome.” Sunil mandated that every person must itch to return to work on Mondays. If not, they were to “shake their boss by the collar” and complain. A wartime culture that somehow made 30,000 crore in quarterly profits feel like a startup.

The Succession and the Decade-Long Bet (2026 Onward)

Sunil is now 68. He recently disclosed his ambition: take Bharti Telecom (the holding company) from 40.4% to 51% controlling stake, to be done over 3-4 years via buybacks and dividends. It will cost roughly 1 lakh crore.

Akil Gupta, who shaped Airtel alongside Sunil for 32 years, resigned in March 2026.

Gopal Vittal, elevated to executive vice-chairman, is positioned on Airtel Africa’s board—crucial because Sunil’s next bet is Africa’s scale.

The new CEO is Shashwat Sharma, 42 years old—the same age Gopal was when Sunil hired him. Shashwat also came from HUL (13 years), also rose through marketing, now promoted from CMO to COO to CEO in 8 years. This signals Sunil’s direction: keep biasing Airtel toward consumer and distribution excellence.

Sunil’s children: Shrain and Kavin (twins) and Isha. Shrain is deputy chairman of Airtel Africa and on the OneWeb board (Airtel’s satellite broadband bet). Kavin ran Hike (a messenger app killed by Jio’s data collapse), now has no Airtel role. Isha has no visible Airtel profile.

The strands Sunil is weaving for the next decade:

Shashwat Sharma strand: Consumer focus, premium positioning, AI and data
Gopal Vittal strand: Long-term adviser, possible Tata-trust-like role for the family
Singtel strand: Gradually buying back stake from Singapore Telco (which will dilute its 28%)
Airtel Africa strand: Independent, growing, multi-billion-dollar bet
OneWeb strand: Satellite broadband (Elon Musk’s Starlink is the rival)
British Telecom strand: Recently tried to raise stake from 25% to 29%, blocked by UK government, but signal is clear
AI and hyperscalers strand: Focusing on cloud, edge computing, digital services
Mittal family strand: Rajan and Rakkesh’s children also have stake; intergenerational transition is complex

The ambition is global: Sunil wants Airtel to be spoken of as a top-five telecom group in the world. He’s willing to make decades-long bets. He’s creating a succession plan that doesn’t rely on one person—a first for Sunil, who’s always been irreplaceable.

Key Takeaways

Survival requires speed, not perfection. When Airtel needed to go pan-India, Akil Gupta said: “Licenses and spectrum are available now. They may not be later. We choose speed over perfection.” Speed won.
Flip the incentive structure. Instead of paying Ericsson per box sold, Akil paid per Erlang used. Instantly, both sides wanted maximum network utilization. This is how you turn a vendor into a partner.
The market teaches faster than consultants. Reliance came and forced Airtel to go mass-market. Jio came and forced Airtel to go premium. Both were optimal; Airtel adapted.
Culture compounds over decades. Airtel’s resilience comes from hiring HUL-trained talent (consumer-obsessed, distribution-savvy) into a founder-driven structure (Sunil calls the shots on big bets). This mix is hard to replicate.
Shed unprofitable customers boldly. Dropping 49 million users looked insane until you realized it freed capacity, improved quality, and forced profitability discipline. Few CEOs have the conviction to do this.
Outsourcing was about freedom, not just cost. By outsourcing to Ericsson, Airtel freed Sunil to raise capital and pursue growth instead of being operationally bound to the network. Same reason Airtel created tower companies.
Position is flexible. Airtel was premium (early), then mass (Reliance disruption), then premium again (post-Jio). Each transition was strategic, not reactive.
Foreign partners are a feature, not a liability. Sunil’s willingness to accept British Telecom nominees, to learn from Singtel, to invite half a plane-load of experts—this openness to outside talent set Airtel apart from insular Indian family businesses.

Claude’s Take

This is a masterclass. The Ken’s Intermission team—with Rohit Krishnan and Sitharam Ganes—has done something remarkable: they’ve taken a dense, technical 30-year history (regulations, spectrum, auctions, tower models, outsourcing contracts) and made it visceral and human. The story lands because it’s not about Sunil vs. competition. It’s about Sunil vs. the unforeseeability of regulation, technology, and rivals—a three-body problem that would have killed most companies.

What makes Airtel’s story singular: Sunil Mittal has almost never been the inventor. Prepaid came from Hutchison. Per-second billing from Tata. 4G data innovation from Jio. But Airtel absorbed these innovations, hammered them, and somehow made them its own. Executives who work there describe an organization that is simultaneously obsessed with growth and ruthless about cost-cutting—a rare trait. Gopal Vittal’s “War on Waste” saved 10,000 crores in costs over four years. Few companies can do both.

The succession planning is audacious: a 42-year-old CEO running a 30,000 crore profit quarter, with a decade-long runway to prove himself. Sunil is betting that good institutions outlive founders. He’s creating a structure that doesn’t depend on his irreplaceability. That’s not something most Indian promoters do.

The only misstep: the 2015 net neutrality play. Airtel and Facebook championing zero-rating (where apps pay for users’ data) was tone-deaf and nearly wrecked Airtel’s reputation. To his credit, Sunil learned. Recently, Airtel tried network slicing (preferential 5G speed for postpaid users) quietly, with lawyers rather than billboards. Even brilliant operators stumble on second-order thinking.

The Africa saga is instructive: you can’t transplant operating models intact. Sunil bought Zain at peak ambition, paid too much, struggled to replicate the Indian playbook, and had to invent new solutions (cloud-based CVM, Airtel Money as a separate business). It took years of losses before it worked. But the bet paid.

If you want to understand how Indian business actually works—regulation, capital raising, talent, timing, succession, the role of foreign partners—watch this documentary. It’s 4+ hours well spent. Shantum’s profile (finance/MBA, generalist, not tied to business/trading) is exactly the audience. You’ll see India’s actual playbook: it’s not theory from business school. It’s survival and adaptation at scale.

Claude’s score: 9/10. This deserves a 9 rather than 10 because it’s long (which is fine for the story) and occasionally gets lost in telecom specifics. But the editorial voice is impeccable, the narrative arc is perfect, and the characters—especially Sunil, Akil, and Gopal—emerge as fully human, not just names.
