UiPath

UiPath sells software licenses and cloud subscriptions for its automation platform. Pricing is based on the number of software robots (called "attended" and "unattended" robots) deployed plus platform fees for orchestration and management tools.

The land-and-expand model works well. A company might start with 5 robots automating invoice processing, then expand to 50 robots handling HR onboarding, then 500 robots across the entire organization.

Revenue per customer grows as automation spreads through departments.

Annual recurring revenue exceeded $1.5 billion in fiscal year 2025. The shift from on-premise licenses to cloud subscriptions has been a major focus, with cloud ARR growing faster than overall revenue.

Professional services and training (UiPath Academy) generate additional 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.

Daniel Dines grew up in communist Romania and taught himself to code as a teenager. After working at Microsoft in Seattle for several years, he returned to Bucharest in 2005 and started a small software company called DeskOver with Marius Tîrcă.

Their initial product was an SDK — a software library that let developers build automation scripts for Windows applications.

For nearly a decade, DeskOver (later renamed UiPath) survived as a tiny bootstrapped company selling development tools. Dines ran the operation from a small apartment in Bucharest with a handful of employees.

Revenue was modest — enough to keep the lights on but not enough to grow. The company was unknown outside a niche developer community.

The pivot came around 2013-2015 when Dines noticed that large enterprises were spending billions on outsourcing repetitive digital tasks — copying data from one system to another, processing invoices, updating spreadsheets. He repositioned UiPath from a developer tool into an enterprise RPA platform: software "robots" that could mimic human actions on a computer screen.

The timing was perfect — every large company had thousands of employees doing exactly this kind of work.

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.

UiPath

UiPath grew through a community-first strategy. UiPath Academy offered free training and certification, creating hundreds of thousands of developers who knew the platform before their employers bought it.

When those developers advocated for UiPath internally, the sales team had warm leads.

The free Community Edition let individual developers and small teams use UiPath at no cost. This bottoms-up adoption mirrored the playbook of Slack and Atlassian — get individual users hooked, then sell enterprise licenses to the organization.

Partners and system integrators drove enterprise deals. Deloitte, Accenture, EY, and PwC all built RPA practices around UiPath, recommending it to their enterprise clients.

These consulting firms had existing relationships with every Fortune 500 CIO, and they directed automation budgets toward UiPath.

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.

AI threatens to leapfrog RPA entirely. Traditional RPA automates repetitive, rule-based tasks by mimicking human clicks.

But generative AI and large language models can understand context, handle exceptions, and process unstructured data — potentially replacing the need for screen-scraping robots. If AI agents can directly interact with APIs and databases, the "robot that clicks buttons" approach may become obsolete.

Competition from Microsoft is the most dangerous threat. Microsoft Power Automate is bundled into Microsoft 365, which virtually every enterprise already pays for.

Offering "good enough" automation for free inside a suite companies already use is devastating for a standalone RPA vendor charging premium prices.

Growth has decelerated. After explosive growth during COVID (when every company rushed to automate), UiPath's revenue growth slowed significantly.

The stock dropped over 80% from its all-time high. CEO Daniel Dines stepped back as CEO in 2023 (Rob Enslin took over, then left, and Dines returned in 2024), creating leadership instability at a critical moment.

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.

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.

Accel led the Series A in 2017 — the first major venture investment after a decade of bootstrapping. CapitalG (Alphabet's growth fund), Sequoia Capital, and IVP participated in later rounds.

Dragoneer, Tiger Global, Alkeon Capital, and Coatue Management invested in the 2019-2021 growth rounds. The April 2021 IPO raised $1.3 billion at a $36 billion valuation.
