WeWork

WeWork's model was fundamentally a real estate arbitrage play dressed up as a tech company. They signed long-term leases on buildings (often 10-15 years), spent millions renovating them, then rented desks and offices to members on month-to-month or annual contracts.

The spread between what they paid landlords and what members paid was supposed to be the profit.

The problem was the mismatch. Long-term obligations on the lease side, short-term flexibility on the revenue side.

In good times, buildings are full and the spread is healthy. In bad times — say, a global pandemic that empties offices — you're locked into paying rent on empty buildings while members cancel month-to-month.

Neumann tried to juice margins with ancillary services: WeWork Labs for startups, Powered by We for enterprise buildouts, and WeWork's own internal ventures. The company also launched WeLive (apartment living) and WeGrow (a private elementary school run by Neumann's wife).

These distractions drained cash without generating meaningful revenue.

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.

WeWork

Adam Neumann was a 6'5" Israeli former naval officer with a talent for fundraising that bordered on hypnosis. Miguel McKelvey was an architect from Oregon with hippie parents who raised him in a commune.

Together in 2010, they launched WeWork from a single building in SoHo, New York — though they actually started with a predecessor called Green Desk in 2008, which was a sustainable coworking space in Brooklyn that they sold to their landlord.

The original concept was dead simple: lease entire floors of commercial buildings at bulk rates, renovate them with trendy design — exposed brick, beer on tap, inspirational quotes on the walls — then sublease individual desks and offices at a premium. The "community" angle was the differentiator.

WeWork wasn't just selling desks. It was selling belonging, networking, the feeling of being a startup founder even if you were a freelance graphic designer working alone.

The timing was perfect. After the 2008 recession, commercial real estate was cheap and available.

The gig economy was exploding. Millennials were entering the workforce with different expectations about work environments.

And startups that couldn't afford traditional office leases needed flexible space. WeWork grew from 1 location to 5 within two years, and the waitlists were long.

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.

WeWork

WeWork grew through sheer aggression funded by seemingly unlimited capital. They would enter a city, sign leases on multiple buildings simultaneously, renovate at premium cost, and absorb losses until locations filled.

The playbook was Uber-style: spend aggressively, dominate the market, worry about profitability later.

The "community" brand was powerful marketing. WeWork events, networking mixers, and the overall vibe attracted a loyal member base that became free ambassadors.

Instagram photos of beautiful WeWork interiors drove organic demand.

Enterprise was the real growth engine. By 2019, over 40% of members were from companies with 500+ employees.

Microsoft, Amazon, and Salesforce all had teams in WeWork. Enterprise clients signed longer contracts and were more predictable than freelancers, but WeWork still spent far more acquiring and building out space than it earned from these relationships.

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.

WeWork

Where to begin? The S-1 filing in August 2019 was a masterclass in red flags.

It revealed that WeWork lost $1.9 billion in 2018 on $1.8 billion in revenue — spending more than a dollar for every dollar earned. Neumann had taken $700 million off the table through stock sales and loans before the IPO.

He owned the "We" trademark personally and charged the company $5.9 million to license it. He had family members on payroll.

He flew on a private jet funded by the company.

The planned $47 billion IPO was pulled in September 2019 after investors revolted. The valuation was slashed.

Neumann was forced out and given a $1.7 billion exit package — for nearly destroying the company. SoftBank took control, cut thousands of jobs, and spent years trying to restructure.

WeWork finally went public via SPAC in 2021 at a $9 billion valuation.

Then COVID hit the commercial real estate market like a meteor. Remote work became permanent for many companies.

WeWork's occupancy plummeted. They filed for Chapter 11 bankruptcy in November 2023, listing $18.7 billion in debt, wiped out the equity, shed hundreds of leases and came back out in June 2024 as a far smaller private company.

The cautionary tale was complete.

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.

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.

WeWork

SoftBank Vision Fund was the largest and most consequential investor, pouring over $10 billion into WeWork across multiple rounds. Masayoshi Son reportedly agreed to invest after a 12-minute meeting with Neumann.

Benchmark was an early investor. JPMorgan Chase provided debt financing.

T. Rowe Price, Fidelity, and Goldman Sachs participated in later rounds.

The company raised more money than most companies ever generate in revenue.
