BUSINESS MODEL

Nuro

For most of its life Nuro sold delivery-as-a-service. Retailers, restaurants and grocery chains paid Nuro to handle the last mile with autonomous vehicles, so instead of employing human drivers a partner simply used Nuro's robot fleet.

The economics are compelling on paper. A human delivery driver costs $15-25 per hour including wages, insurance, and vehicle costs.

A Nuro vehicle costs money to build and maintain, but once deployed, it operates nearly 24/7 with no driver wages, no tips, and no breaks. The breakeven point comes when the fleet reaches sufficient utilization in a market.

That was the plan, anyway. In 2024 Nuro changed course and stopped trying to run a delivery service itself.

The business now is licensing the autonomy stack — the Nuro Driver — to carmakers and mobility companies, which is a far cheaper way to grow than building and operating your own fleet. FedEx, Domino's, Kroger, Walmart and 7-Eleven had all tested or deployed the delivery bots before the pivot.

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.

HOW THEY STARTED

Nuro

Dave Ferguson and Jiajun Zhu were both principal engineers at Google's self-driving car project (later Waymo). Ferguson led the machine learning and motion planning teams.

Zhu worked on perception — teaching cars to see and understand the world. They were two of the most senior engineers in autonomous driving.

In 2016, they left Google with a contrarian insight: the hardest part of self-driving cars wasn't the technology. It was the stakes.

A robo-taxi carrying passengers needs to be essentially perfect — any accident could injure or kill someone inside and destroy public trust. But a delivery vehicle carrying groceries?

If it gets in a fender bender, the worst case is squished bananas.

By removing the human from the vehicle, Nuro eliminated the most complex variable in autonomous driving safety. Their vehicles are small, light (under 1,200 pounds), and slow (max 25 mph on surface streets).

If one hits a pedestrian, the impact energy is dramatically lower than a 4,000-pound car going 40 mph. This let them get regulatory approval years before full-size robo-taxis.

The first prototype, R1, looked like a cartoon car — about half the width of a normal vehicle, with no windows, no mirrors, and no driver's seat. Just cargo space and sensors.

They revealed it in 2018 and began testing in Scottsdale, Arizona with Kroger for grocery deliveries.

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.

HOW THEY GREW

Nuro

Nuro's strategy is to become the default autonomous delivery infrastructure for major retailers. Rather than build a consumer-facing delivery app (competing with DoorDash and Instacart), Nuro provides the robotic fleet that powers deliveries for existing brands.

The partnership-first approach reduces go-to-market friction. Kroger, Walmart, and FedEx already have massive customer bases and order volumes.

Nuro provides the autonomous last-mile delivery layer. The retailer gets lower delivery costs.

Nuro gets guaranteed demand.

That was the original plan. Houston and Mountain View were the early markets, mapped city by city, each one needing its own regulatory approval before a single vehicle moved.

It was slow and it was expensive, and in 2024 Nuro gave it up in favour of licensing its self-driving software to companies that already build and operate vehicles.

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.

THE HARD PART

Nuro

The technology still has limitations in complex scenarios. Nuro vehicles operate on surface streets at low speeds — they can't handle highways, heavy snow, or extremely dense urban environments like Manhattan.

This limits the addressable market to suburban deliveries in good weather, which is a large market but not the whole market.

The path to profitability is long. Building custom autonomous vehicles is extraordinarily capital-intensive.

Each generation of vehicle requires hundreds of millions in design, engineering, testing, and manufacturing. Nuro has burned through most of its $2.1 billion in funding and laid off 30% of staff in 2023, signaling the cash crunch is real.

Competition comes from multiple directions. Amazon is developing its own delivery robots (Scout, though paused).

Waymo could pivot to autonomous delivery, though Cruise is no longer a threat after GM shut it down at the end of 2024. Established delivery companies could partner with other autonomy providers.

And human drivers remain cheaper than robots at current scale — the economics only flip once Nuro has hundreds or thousands of vehicles per market.

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.
