Zero to IPO: The TCS Story
In 1968, there was no Indian IT industry to speak of. Computers were rare, expensive machines locked inside a few large organisations, and "software exports" was not yet a phrase anyone used. Tata Consultancy Services (TCS) did not just join that industry — it invented it in India, one punched-card project at a time, and then listed in 2004 in what was then the largest IPO by a private-sector Indian company.
This is the story of how a small division inside Tata Sons became India's largest IT services company — and what its IPO meant for the investors who backed it.
The Founding Moment: A Computer Centre Nobody Wanted
TCS traces its roots to the Tata Computer Centre, set up in 1966 at Nirmal Building, Nariman Point, Mumbai, to handle the computing needs of Tata group companies. When the centre went under-utilised, Bombay House decided to remodel it. In 1968, Tata Consultancy Services was born as a division of Tata Sons, under the leadership of J.R.D. Tata and its first chief, F.C. Kohli — widely remembered as the father of the Indian IT industry.
The early brief was modest: management and technology consultancy for group companies. The ambition, as Kohli saw it, was much bigger — to prove that Indians could write software for the world.
Early Struggles: Selling Software Before India Believed In It
The 1970s were not kind to would-be software exporters. India had little computing infrastructure, strict import controls, and almost no domestic market for software services. TCS's breakthrough came in 1973, when it began a partnership with Burroughs to distribute and support Burroughs products in India and build software for export to Burroughs units and clients worldwide.
According to Tata's own history of the company, one early project became historic: converting a hospital accounting system from Burroughs Medium Systems COBOL to Burroughs Small Systems COBOL — done without a Burroughs computer, using a filter in assembly language on TCS's ICL 1903 machine. It was, Tata records, the first recorded instance of offshore software delivery done using automation.
By 1976, TCS had crossed $1 million in export revenues and won the top exporter award from the Engineering Export Promotion Council. In 1979, it opened its first overseas sales office in New York, headed by S. Ramadorai. The offshore model — work done in India for clients abroad — that the whole Indian IT industry runs on today was being built, project by project, in those years.
The Growth Engine: Big Deals, Quality, and the Y2K Windfall
The 1980s and 1990s turned TCS from a services shop into a global delivery machine:
- 1981: A 135-person-year project for Western Trust and Savings Ltd gave TCS deep retail-banking expertise and mastery of IBM mainframe technology. The same year, Kohli set up the Tata Research Development and Design Centre (TRDDC), TCS's research arm.
- 1989: A $10 million deal with the Swiss Securities Clearing Corporation (SEGA) to build the world's first real-time domestic and cross-border securities clearing system marked TCS's entry onto the global stage.
- 1996: Kohli stepped down after 22 years at the helm; Ramadorai took over as CEO.
- 1997: TCS set up its Ambattur "software factory" and remediated about 700 million lines of code for the Y2K bug, using automated tools it had built for the job.
- Early 2000s: The Global Network Delivery Model — delivery centres across countries working as one factory — took shape, and TCS signed its first $100 million deal, with GE Medical Systems, then the largest single contract ever won by an Indian software services company.
TCS crossed $1 billion in annual revenue in 2003. Ramadorai unveiled the vision "Top 10 by 2010" — a goal TCS met in 2009, ranking among the world's top 10 IT service providers by revenue, profitability, headcount and market capitalisation.
The Road to the IPO: Hiving Off a Division, Listing a Giant
Until 2004, TCS was a division of Tata Sons, not a listed company. In late 2002, the decision to hive off and list TCS was formalised: the TCS division was transferred to a separate company, Tata Consultancy Services Ltd, so it could be offered to the public.
The IPO opened on 29 July 2004 and closed on 5 August 2004. The details, per the issue documents:
| IPO detail | Figure |
|---|---|
| Price band | Rs 775–900 per share (face value Re 1) |
| Final issue price | Rs 850 per share |
| Issue size | 5,54,52,600 shares, aggregating Rs 4,713.47 crore |
| Structure | 2,27,75,000 fresh shares + 3,26,77,600 shares offered for sale by Tata Sons and other shareholders |
| Green shoe option | 83,17,880 additional shares by Tata Sons (Rs 707.02 crore) |
| Subscription | 7.7 times overall |
| Listing date | 25 August 2004, on BSE and NSE |
The issue was oversubscribed several times over on the very first day. As CFO Samir Seksaria later recalled in a LinkedIn post on the IPO's 20th anniversary, quoted by ET Now, it signalled "robust investor confidence not only in TCS but also in the future of India as a technology powerhouse." At the time it was the largest IPO by a private-sector Indian company, and the first billion-dollar IPO in Indian history.
Listing Day: A Sparkling Debut
On 25 August 2004, TCS listed at Rs 1,050 on BSE — a 23.5% premium to the Rs 850 issue price — and at Rs 1,198 on NSE, a 41.8% premium, according to Business Standard's listing-day report. It closed the day at Rs 987.50 on BSE, still 16.17% above the issue price, and became the first scrip to rank among the top five companies by market capitalisation on its very debut.
The wealth math since then is the stuff of Indian market legend. One share bought at Rs 850 in the IPO, held through the 1:1 bonus issues of 2006, 2009 and 2018, was worth over Rs 20 lakh per Rs 1 lakh invested by August 2024 on ET Now's calculation — before dividends. Tata Sons chairman N. Chandrasekaran told shareholders in 2021 that a single IPO share was then worth around Rs 28,000, a return of over 3,000% in 17 years.
Where TCS Stands Today
After the IPO, TCS kept scaling through every technology wave — the "Default is Digital" era under Chandrasekaran, the Business 4.0 framework, cloud, and now AI. It became the first Indian IT company to cross $100 billion in market capitalisation (2018), and it remains India's largest IT services company and second-largest listed company overall.
The latest quarter underlines the scale: for Q2 FY27 (July–September 2026), reported on 8 October 2026, TCS posted revenue of Rs 73,188 crore (up 11.2% year-on-year) and net profit of Rs 13,884 crore (up about 15%), with annualised AI revenue crossing $3.1 billion — over 10% of revenue — and a workforce of 5,98,056 people. The shares traded around Rs 2,500 in late October 2026, with a market capitalisation of roughly Rs 8.9 lakh crore.
The leadership arc is equally long: Kohli (1968–1996) to Ramadorai (1996–2009) to Chandrasekaran (2009–2017) to Rajesh Gopinathan (2017–2023) to K. Krithivasan, the current CEO and MD.

Takeaways for Investors and Entrepreneurs
- Build the category before you chase the market: TCS spent 30 years creating India's offshore model before the world wanted it at scale. When demand arrived, it was already the default.
- Process is a product: From TRDDC to the Global Network Delivery Model, TCS's edge was never one clever project — it was repeatable, tool-driven delivery.
- Leave something on the table: Pricing the IPO at Rs 850, below the top of the band, bought goodwill that compounded for two decades.
- Reinvent before you must: Mainframes to Y2K to e-business to digital to cloud to AI. Each wave arrived while the previous one was still paying.

Conclusion
TCS's journey is the rare story where the company and the industry are the same story. It started as an under-used computer room in a Mumbai office building, taught itself to sell Indian software to the world before anyone believed that was possible, and then gave public investors a front-row seat — at Rs 850 a share — to the next twenty years of that compounding. For entrepreneurs, the lesson is patience with process; for investors, it is what happens when a great business lists at a fair price and is simply left alone to work.
