Flipkart

Marketplace model — Flipkart connects third-party sellers with consumers and takes a commission on every transaction, typically 5% to 25% depending on the category. Also operates a first-party retail business buying and reselling products directly, particularly in electronics and fashion.

Revenue streams include seller commissions, advertising (brands pay to appear in search results and banners), logistics services (Flipkart's in-house delivery network, Ekart, also serves other companies), and Flipkart Plus (loyalty program). The company runs periodic mega-sales — Big Billion Days — that generate billions in GMV over a few days, essentially India's version of Prime Day.

OpenAI makes money primarily through API access and subscriptions. The API charges developers per token (roughly per word) for using GPT models in their applications.

ChatGPT Plus costs $20/month for individual users, ChatGPT Team is $25-30/user/month, and ChatGPT Enterprise is custom-priced. Microsoft pays OpenAI licensing fees and also resells OpenAI models through Azure OpenAI Service.

OpenAI's annualised revenue ran past $13 billion during 2025 and kept climbing from there, which is the kind of growth curve that normally only exists in a pitch deck.

Sachin Bansal and Binny Bansal — not related despite the shared surname — both worked at Amazon in its early days. They moved back to India in 2007 and started Flipkart as an online bookstore, literally copying the Amazon playbook from 1994.

Their first order was a book called "Leaving Microsoft to Change the World," which is almost too on-the-nose. But India in 2007 was nothing like America in 1994.

Internet penetration was low, credit cards were rare, delivery infrastructure was nonexistent, and most people had never bought anything online. The Bansals had to invent solutions for problems Amazon never faced.

Cash-on-delivery became the default payment method. They built their own logistics network because India Post couldn't handle e-commerce volumes.

Every assumption that worked in the US had to be rebuilt from scratch for India.

OpenAI

OpenAI was founded in December 2015 as a nonprofit AI research lab. The founding donors — including Elon Musk, Sam Altman, Peter Thiel, Reid Hoffman, and Jessica Livingston — pledged $1 billion with a mission to build artificial general intelligence (AGI) that would benefit all of humanity.

The idea was that AI was too important and too dangerous to leave in the hands of Google alone.

Sam Altman became chairman while Greg Brockman (former CTO of Stripe) became president. Ilya Sutskever, one of the most respected AI researchers alive, left Google Brain to become chief scientist.

The early team was stacked with world-class researchers who published their work openly — hence "Open" AI.

But AI research turned out to be staggeringly expensive. Training large models required millions of dollars in compute.

In 2019, OpenAI created a "capped-profit" subsidiary — investors could earn up to 100x their money, but profits beyond that would flow to the nonprofit. Microsoft invested $1 billion.

The mission was still to save humanity. The method now involved making a lot of money first.

Category expansion from books to electronics to fashion to groceries — each new category brought new customers and increased purchase frequency. Cash-on-delivery removed the trust barrier for first-time online shoppers.

Building Ekart logistics gave Flipkart delivery reach into tier-2 and tier-3 cities that no third-party carrier could serve. Big Billion Days mega-sale events trained Indian consumers to shop online with massive discounts.

Acquisition strategy — bought Myntra (fashion), Jabong (fashion), eBay India (marketplace), and PhonePe (payments) to consolidate the market. Walmart's $16 billion acquisition in 2018 provided unlimited capital to compete with Amazon India.

Mobile-first design because most Indian consumers access the internet through smartphones, not computers.

ChatGPT's launch in November 2022 was the growth strategy — it just wasn't planned that way. The team expected a modest research preview.

Instead, ChatGPT hit 1 million users in 5 days and 100 million monthly active users in 2 months, making it the fastest-growing consumer application in history. The product went viral because it felt like magic — for the first time, anyone could have a natural conversation with a machine that seemed to understand them.

The Microsoft partnership provided distribution at massive scale. Microsoft integrated OpenAI models into Bing, Office 365 (Copilot), GitHub (Copilot), and Azure.

Overnight, hundreds of millions of Microsoft users had access to OpenAI technology. Microsoft's $13 billion investment was the largest AI bet in history and gave OpenAI nearly unlimited compute.

The API created an ecosystem. Thousands of startups built products on top of OpenAI's models — from customer service bots to coding assistants to content generators.

Each API customer locked themselves into OpenAI's ecosystem, creating switching costs and recurring revenue.

Amazon India is a relentless competitor with Jeff Bezos publicly committing billions to win the market. Regulatory uncertainty — Indian e-commerce regulations around foreign ownership, deep discounting, and marketplace rules change frequently and can disrupt business models overnight.

Profitability has remained elusive despite massive scale — the combination of deep discounts, logistics costs, and competitive spending keeps margins thin. The Walmart acquisition created enormous pressure to demonstrate returns on a $16 billion investment.

Founder drama — Sachin Bansal was forced out after the Walmart deal over allegations of personal misconduct, creating leadership turbulence. And the fundamental challenge of e-commerce in India: a price-sensitive market where consumers will switch platforms for a 50-rupee discount.

OpenAI

The board crisis of November 2023 nearly destroyed the company. The nonprofit board fired Sam Altman as CEO on a Friday, citing a loss of confidence.

Within 48 hours, 95% of employees threatened to quit and follow Altman to Microsoft. By Tuesday, Altman was reinstated and the board was restructured.

The incident exposed the fundamental tension between OpenAI's nonprofit governance and its for-profit ambitions — a tension it finally addressed in late 2025 by restructuring the business as a public benefit corporation sitting under the original nonprofit.

The cost of training frontier models is eye-watering. Each new GPT generation costs hundreds of millions to train.

OpenAI is reportedly spending over $7 billion annually on compute. The company is burning through cash faster than almost any startup in history, which is why it keeps raising at higher and higher valuations.

If revenue growth slows before costs stabilize, the math gets ugly.

Safety concerns are not going away. Multiple prominent researchers have left OpenAI over disagreements about the pace of development versus safety research.

Ilya Sutskever, the chief scientist who was central to the board's decision to fire Altman, left in 2024 to start a safety-focused AI lab. The public debate about whether OpenAI is moving too fast — and whether its safety commitments are genuine — grows louder with every capability improvement.

Flipkart Quick — hyperlocal delivery for groceries and essentials.

OpenAI

ChatGPT is the consumer chatbot — the product that made AI mainstream overnight. The flagship GPT models are multimodal, handling text, images, and audio in one system.

The OpenAI API lets developers integrate GPT into any application. DALL-E generates images from text descriptions.

Whisper transcribes and translates audio. Sora generates videos from text prompts.

GPT Store lets users create and share custom GPT agents. ChatGPT Enterprise gives businesses a private, secure version of ChatGPT with admin controls and no data training.

Flipkart

Key investors before the Walmart acquisition included Tiger Global Management, SoftBank Vision Fund, Accel Partners, Naspers, and Tencent. Walmart acquired 77% of Flipkart for $16 billion in 2018, the largest e-commerce acquisition in history at the time.
