AT A GLANCE
FUNDING HISTORY
OpenAI
Sea Group
BUSINESS MODEL
OpenAI
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.
Sea Group
Sea runs three distinct businesses under one roof, and the genius of the structure is how they feed each other.
Garena is the gaming division. It develops and publishes games — most famously Free Fire, which Sea built itself after years of just licensing other people's games.
Free Fire launched in 2017 and became a phenomenon in emerging markets. It's a battle royale game optimized for low-end Android devices and slow internet connections.
Exactly the phone most people in Southeast Asia, Latin America, and India actually own. Garena makes money through in-game purchases — skins, characters, seasonal passes.
At its peak, Free Fire had over 100 million daily active users.
Shopee is the e-commerce marketplace. It operates like a hybrid of Amazon and eBay — sellers list products, buyers purchase, Sea handles payments, logistics coordination, and marketing.
Shopee makes money through advertising, transaction fees, and value-added services for sellers. It's now the dominant e-commerce platform in Southeast Asia and has a significant presence in Brazil.
SeaMoney is the fintech arm. It offers mobile wallets, digital payments, buy-now-pay-later, and banking services through MariBank in Singapore.
The pitch is simple: hundreds of millions of people in Southeast Asia are unbanked or underbanked. Give them a mobile wallet tied to their Shopee account and they'll use it for everything.
It's the super-app play, executed patiently.
HOW THEY STARTED
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.
Sea Group
Forrest Li moved from China to Singapore in 2005 to do his MBA at Stanford. He didn't go back.
In 2009, he founded Garena — which literally means 'Global Arena' — as an online gaming platform for Southeast Asia. The region was massively underserved.
Hundreds of millions of young, mobile-first users with low PC penetration but exploding smartphone adoption. Nobody was building for them.
Li saw that gap and went straight at it.
Garena started by licensing popular PC games — League of Legends, FIFA Online — and localizing them for markets like Indonesia, Thailand, Vietnam, and the Philippines. It was a straightforward licensing model, unglamorous, not the kind of thing that gets TechCrunch headlines.
But it worked. Garena quietly became the dominant gaming platform across Southeast Asia.
The company rebranded to Sea Limited in 2017 when it IPO'd on the New York Stock Exchange, raising $884 million. By then, Li had already launched Shopee in 2015 — an e-commerce marketplace — and SeaMoney, a digital payments and financial services arm, was taking shape.
Three businesses. One holding company.
The bet was that gaming would fund the others until they could stand on their own. That's exactly what happened.
HOW THEY GREW
OpenAI
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.
Sea Group
The counterintuitive move was using gaming to subsidize e-commerce. Most tech companies pick a lane.
Sea used Garena's cash flows — which were enormous when Free Fire was at its peak — to fund Shopee's aggressive, money-losing expansion. They didn't need to raise debt or dilute shareholders to burn cash in new markets.
The gaming division was basically an ATM.
Free Fire itself was a masterclass in product-market fit. Instead of porting a premium game to low-end markets and watching it fail, Sea built a battle royale game from scratch that ran on 1GB RAM Android phones with patchy 3G connections.
The game was optimized for exactly the hardware that 800 million people in emerging markets actually owned. Nobody else was doing that.
Shopee's growth hack was localization taken to an almost absurd degree. They didn't just translate the app.
They hired local teams in every market, ran country-specific campaigns, integrated local payment methods, and partnered with local logistics providers. In Brazil, they ran Shopee-branded motorbike delivery.
In Indonesia, they integrated with hundreds of local courier companies. The playbook was: be more local than the locals.
The final piece was the flywheel. A Garena user downloads Free Fire, spends money on in-game items using SeaMoney's wallet, then starts buying physical goods on Shopee with the same wallet.
Three products, one ecosystem, one user. That's the compounding effect Li was building toward from day one.
THE HARD PART
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.
Sea Group
The post-pandemic collapse was brutal and nearly existential for the stock, if not the business. During COVID, Sea was the perfect story — gaming was up, e-commerce was up, digital payments were up.
The stock hit $372 in October 2021. Market cap touched $200 billion.
Sea was the most valuable company ever to come out of Southeast Asia.
Then the world opened back up. Free Fire's daily active users fell off a cliff as people left their homes again.
Garena had funded the empire, and now the empire's funding engine was broken. Sea lost its license to publish Free Fire in India after the Indian government banned Chinese-linked apps.
India had been a massive market. Gone overnight.
Sea responded by cutting costs aggressively — laying off staff, retreating from markets like France, Spain, Poland, and India where Shopee had expanded without yet reaching profitability. The stock fell from $372 to under $40 by early 2023.
A 90% drawdown. That's not a correction.
That's a reset.
The deeper challenge is structural. Shopee competes with Lazada (backed by Alibaba), TikTok Shop (which has exploded in Southeast Asia), and increasingly with Temu and Shein.
These are not small competitors. TikTok Shop in particular has disrupted the e-commerce landscape in Indonesia and Thailand faster than most analysts expected.
Sea has scale and local knowledge, but the fight for Southeast Asia's e-commerce market is far from over.
THE PRODUCTS
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.
Sea Group
Free Fire is the crown jewel — a mobile battle royale game with over 100 million daily active users at its peak, built specifically for low-end Android devices in emerging markets. It's been the most downloaded mobile game globally multiple times and remains dominant across Southeast Asia and Latin America despite declining from its COVID peak.
Shopee is Sea's e-commerce marketplace and the business with the highest long-term ceiling. It operates across Singapore, Malaysia, Indonesia, Thailand, Vietnam, Philippines, Taiwan, and Brazil.
It's consistently ranked the most-visited e-commerce site in Southeast Asia. The app includes livestream shopping, local seller tools, Shopee Pay, and Shopee Food in select markets.
SeaMoney — now operating as the financial services umbrella — includes ShopeePay (mobile wallet integrated with the Shopee checkout), SeaBank (a licensed digital bank in the Philippines and Indonesia), and MariBank (a digital bank in Singapore). The pitch is financial inclusion for the underbanked, backed by transaction data from Shopee.

Sea Group
Sea went public in 2017 without needing a late-stage mega-round from the usual suspects. But it had institutional backing from early on.
Tencent is the most significant external shareholder — the Chinese gaming giant held a roughly 22% stake at various points, which gave Sea both credibility in gaming and a complicated geopolitical headache as anti-China sentiment grew in Southeast Asia and the U.S.
Naveen Tewari's General Atlantic and other growth equity funds participated in rounds before the IPO. Post-IPO, Sea attracted attention from large institutional investors including T.
Rowe Price, BlackRock, and various sovereign wealth funds drawn to the Southeast Asia growth story.
Masayoshi Son's SoftBank also took a stake — consistent with SoftBank's bet on emerging market consumer internet platforms. The Tencent relationship is the most interesting one because it's both a competitive asset (access to gaming IP and distribution) and a liability (political risk in markets sensitive to Chinese corporate influence).
