Aditi Bhosale Walunj was running her family’s petrol pump when she built Repos Energy, the fuel startup Ratan Tata backed

Most fuel in India is bought the same way it has been for decades. You drive to a pump, you queue, you fill up, you leave. Aditi Bhosale Walunj looked at that routine from the inside, because her family owned one of those pumps, and she decided it did not have to work that way. The company she co-founded, Repos Energy, brings the fuel to the customer instead of the other way round. It is the kind of idea that sounds obvious once it exists and sounds impossible before.

What makes her story worth telling is not just the model. It is who built it and how. Aditi was in her twenties, with a degree in chemistry and forensic science rather than an MBA, and no startup pedigree to lean on. Yet the business she and her husband started in a mid-sized city went on to win a personal investment from Ratan Tata, a man famous for backing almost no one. This is how that happened.

Early life and a family that sold fuel

Aditi grew up in Pune, in a family with its hands in several businesses: construction, hospitality, and petrol pumps. Fuel retail was the family trade she ended up closest to. By her mid-twenties she was helping run that side of things, which meant she learned the industry from the ground, not from a case study. She knew what a tanker schedule looked like, what a delayed delivery cost, and how much of the business ran on paperwork and phone calls.

Her training was in the sciences. She studied chemistry and forensic science, and later added executive education to the mix. It is an unusual background for someone who would end up building an energy-distribution company, and in a way that is the point. She came at a very old industry without the assumptions that people who had spent their whole careers in it tended to carry.

The power cut that became a business

The origin moment, as the founders tell it, was a power cut in Pune in 2017. Aditi was coordinating between fuel tankers at the family pump, trying to keep things moving, when the practical problem in front of her turned into a bigger question. Diesel is what keeps generators, construction sites, telecom towers and factories running when the grid falters. Yet getting that diesel still meant someone driving to a pump with cans, or a fuel truck operating with almost no oversight. Why, she wondered, could fuel not be ordered and delivered as reliably as everything else had started to be?

That question became Repos Energy, founded in 2017. She built it with her husband, Chetan Walunj, who serves as the company’s chief executive, and the early team included co-founder Aparajit Subramanian. The division of labour was clear enough: a business that needed both deep fuel-industry knowledge and a willingness to rethink the whole model from scratch. Aditi brought both the family grounding in fuel and the outsider’s refusal to accept how things had always been done.

The petrol pump on wheels

The core product is easiest to picture as a petrol pump that drives to you. Repos puts a certified mobile dispenser on a vehicle, fitted with a fuel tank and the metering and safety equipment a normal retail pump has, and sends it to wherever the diesel is needed. The company calls these mobile units its version of a retail outlet on wheels. A construction site, a factory, a housing society running backup generators, a fleet depot: instead of sending people and cans to a pump, the pump comes to them.

Underneath the vehicle sits the part Aditi and her team care most about, which is software. Repos built an IoT and cloud platform to track every litre, log each transaction, handle payments and give both the customer and the fuel entrepreneur a clear record of what moved where. That matters in an industry where fuel is valuable, easy to pilfer and historically loosely measured. The pitch is not only convenience. It is accountability, applied to a commodity that rarely had much of it.

The model also created a role for small operators. Rather than own every vehicle itself, Repos enables what it calls fuel entrepreneurs to run mobile dispensers under its platform, which is how the network has spread across dozens of Indian cities without the company having to build all of it directly. Indian Oil, the state-owned fuel giant, partnered with Repos to enable doorstep diesel delivery, which gave the model a level of official backing that a fuel startup badly needs.

The letters to Ratan Tata

The part of the story people remember is the Ratan Tata investment, and it deserves the attention. Aditi and Chetan had no obvious route to one of the most revered industrialists in the country. By their own account, they wrote to him, reached out through the people around him, and eventually waited the better part of a day to meet him at his Mumbai residence. He heard them out, and he decided to back them.

Ratan Tata, who died in October 2024, was known for being extremely selective with his personal investments, favouring young founders he found genuine over polished pitches. That he put his own money into a doorstep-fuel company run by a couple from Pune, and reportedly returned to back them more than once, told the market something no deck could. In 2022 Repos raised a pre-Series A round of around 56 crore rupees, a mix of equity and debt, in which Tata took part alongside other investors. For a company in an infrastructure-heavy, capital-hungry business, that validation mattered as much as the cheque.

The numbers so far

Repos did not start big. In its first couple of years the monthly turnover grew from roughly 70,000 rupees to about 2 crore, and the core team went from two people to around 150. Those are the numbers of a company finding its feet, and they are worth remembering against what came later, because the jump was not instant. By the 2022-23 financial year the company reported revenue of about 72 crore rupees, and it has publicly aimed much higher since, talking about a run rate in the region of 200 crore. That last figure is a stated target rather than an audited result, and it is fair to treat it as ambition until the filings confirm it.

On the ground, the network had grown to hundreds of mobile dispensers across dozens of cities, moving a large and rising volume of diesel every month. The exact counts shift with each new report, which is normal for a company expanding this fast, so the honest summary is a range rather than a single number: this is now a meaningful operation across much of urban India, not a pilot. Aditi’s own recognition has grown with it. She was among a group of twenty-five women entrepreneurs invited to meet the President of India, Droupadi Murmu, a nod to how far the Pune experiment had travelled.

Aditi Bhosale Walunj’s net worth, and the honest answer

Search her name and a net-worth figure will often appear. Treat it with suspicion. Repos Energy is a privately held company, its ownership is split between the founders, their family, institutional investors and Ratan Tata’s estate, and none of that is disclosed in a way that lets anyone calculate a credible personal fortune. A headline number attached to a private founder is usually a guess, and we will not pretend otherwise.

What can be said responsibly is this. Aditi is a co-founder of a venture-backed company that has raised tens of crores, carried an estimated valuation in the hundreds of crores in its most recent reported rounds, and generates real revenue. On paper her stake is clearly valuable. Whether it translates into the kind of liquid wealth the net-worth sites imply depends entirely on how Repos performs and whether there is ever an exit, neither of which anyone can price today. The accurate answer to the net-worth question is a shrug and a pointer to the company’s actual numbers.

What Repos is really solving

It helps to step back from the vehicles and see what the company is actually attacking, which is waste and opacity in how India moves fuel. Diesel that sits unused, trips made only to refuel, theft that goes unmeasured, demand that cannot be matched to supply because nobody has the data: these are the inefficiencies of a system that never got digitised. Repos is, at heart, a software company that happens to drive tankers, and its real asset is the record of who needs how much fuel, where and when.

That framing is also why the business can grow beyond diesel delivery. Energy distribution is shifting, slowly, and a platform that already knows a region’s fuel demand in fine detail is well placed for whatever comes next, from cleaner fuels to the data services that an energy network generates. Aditi has spoken about Repos as an energy company rather than a delivery company, and the distinction is the whole thesis. Delivery is the wedge. The data and the network are the bet.

What Aditi Bhosale Walunj’s story teaches Indian founders

The first lesson is about where good ideas actually come from. Aditi did not spot her opportunity in a trend report. She found it standing in her family’s own business, watching a problem she had seen a hundred times and finally asking why it had to stay that way. Proximity to a messy, old, unglamorous industry is an advantage, not a limitation, and some of the best companies come from founders who know a boring sector intimately enough to see what everyone else has stopped noticing.

The second is about credibility when you have none to start with. A young couple from Pune, outside the usual startup networks, got to Ratan Tata by being persistent and sincere rather than connected. They wrote, they waited, they showed up. It is a reminder that the door to the person who can change your trajectory is often less locked than it looks, and that conviction, clearly expressed, can substitute for a pedigree you do not have.

The third is quieter. Aditi built this with her husband and a small founding team, in a business that is physical, regulated and hard, far from the lighter consumer apps that attract most of the attention. Not every important company is a glossy D2C brand. Some of the most consequential ones are the unglamorous infrastructure plays, and there is room in that world for a woman who understands the plumbing of an industry better than the incumbents do.

It operates mobile dispensers (essentially petrol-pump equipment mounted on vehicles) backed by an IoT and cloud platform that meters and tracks every litre. It has partnered with Indian Oil and operates across dozens of Indian cities.

Did Ratan Tata invest in Repos Energy?

Yes. Ratan Tata personally backed Repos Energy, reportedly more than once. In 2022 the company raised a pre-Series A round of around ₹56 crore (a mix of equity and debt) in which Tata took part alongside other investors. By the founders’ account, they reached him through persistent outreach and a long wait to meet him in person.

Who are the founders of Repos Energy?

Repos Energy was founded in 2017 by Aditi Bhosale Walunj and her husband Chetan Walunj, with Aparajit Subramanian also named as a co-founder. Chetan Walunj serves as chief executive; Aditi is a co-founder who has driven the company’s strategy and brand.

What is Aditi Bhosale Walunj’s net worth?

There is no verified public net-worth figure. Repos Energy is privately held and its ownership is not disclosed, so any specific number online is an estimate. What is known is that she co-founded a venture-backed company that has raised tens of crores and been valued in the hundreds of crores in recent reported rounds, which makes her stake valuable on paper but impossible to price precisely.

What can founders learn from her story?

Two things stand out. Good ideas often come from deep familiarity with an old, unglamorous industry; Aditi found hers inside her family’s fuel business. And credibility can be earned through persistence: a young couple from Pune reached Ratan Tata by writing, waiting and showing up, without the networks most funded founders rely on.
