GitPod

Airbnb

Airbnb is a two-sided marketplace. Hosts list their homes, apartments, treehouses, or whatever else they've got.

Guests book and pay through the platform. Airbnb takes a cut from both sides — roughly 3% from hosts and up to 14% from guests as a service fee.

That's it. They don't own a single property.

They just built the world's largest hotel chain without owning a single bed.

GitPod

GitPod started as freemium: a free tier of monthly cloud hours, paid plans for more hours and bigger workspaces, and enterprise contracts with self-hosted and dedicated options. As Ona it shifted toward enterprise contracts for running AI coding agents inside a customer's own cloud, with governance and security controls.

It said enterprise annual recurring revenue quadrupled year over year before the rename. OpenAI acquired the company in 2026, and existing customer commitments continue to be supported.

In 2007, Brian Chesky and Joe Gebbia were two Rhode Island School of Design grads living in San Francisco and struggling to make rent. A big design conference was coming to town and every hotel was booked solid.

They bought three air mattresses, put up a simple website called AirBed & Breakfast, and charged $80 a night including a homemade breakfast. Three strangers actually showed up.

That was it — the entire origin story of a $75 billion company is three air mattresses and desperation.

They recruited Nathan Blecharczyk, a Harvard-trained engineer Joe knew, to build the real website. But nobody wanted to fund them.

They applied to 15 investors and got rejected by every single one. To keep the company alive during the 2008 election, they designed limited-edition cereal boxes — Obama O's and Cap'n McCain's — and hand-assembled 500 of each.

They sold the Obama O's for $40 a box and made $30,000. That cereal money literally kept Airbnb from dying.

Paul Graham at Y Combinator finally let them into the Winter 2009 batch — reportedly because the cereal stunt proved they were "cockroaches" who would never die. YC invested $20,000.

Within a few months, Sequoia Capital led a $600,000 seed round. The rest is history.

GitPod

The GitPod team came out of TypeFox, a German developer tools company in Kiel behind the Theia cloud IDE framework. Sven Efftinge and his colleagues realized the biggest pain point was not the editor itself but the environment.

Developers spent hours configuring machines, installing dependencies and debugging "it works on my machine" problems.

They launched GitPod to provide instant, automated cloud development environments. One click from a GitHub or GitLab repo opened a fully configured workspace with dependencies installed and tools ready.

Johannes Landgraf, who became CEO, and CTO Christian Weichel later led the company through its rename to Ona in 2025 and its sale to OpenAI in 2026.

The early growth was pure hustle. Chesky and Gebbia flew to New York — their biggest market — and went door to door visiting hosts.

They noticed the listings with bad photos got no bookings. So they offered free professional photography to every host.

Bookings exploded. That single move — better photos — was probably worth more than any ad campaign they ever ran.

They also pulled one of the most legendary growth hacks in startup history. They reverse-engineered Craigslist's posting system so that Airbnb hosts could cross-post their listings to Craigslist with one click.

Craigslist had millions of people looking for rentals. Airbnb had none.

The hack funneled Craigslist's traffic straight into Airbnb. It was borderline shady and absolutely brilliant.

Word of mouth did the rest. Every guest who had a great stay told their friends.

Every host who made easy money told their neighbors. The product sold itself because both sides benefited immediately.

By 2015, Airbnb had more listings than the top five hotel chains combined.

GitPod

GitPod grew through open source community adoption and one-click integrations with GitHub, GitLab and Bitbucket, where a "Gitpod" button on a repo launched a ready workspace. It later moved upmarket to banks and pharmaceutical companies that wanted cloud development under tight security.

In 2025 it bet the company on AI agents, renaming itself Ona and claiming its own agents were producing most of its merged code. That bet ended in a sale to OpenAI in 2026.

Regulation. Full stop.

Cities around the world have gone to war with Airbnb. New York, Barcelona, Amsterdam, Paris, Berlin — all have passed laws restricting or outright banning short-term rentals.

The hotel lobby has spent hundreds of millions fighting Airbnb at every level of government. In New York City, a 2023 law essentially banned most Airbnb listings overnight.

Then COVID hit. In March 2020, Airbnb's business dropped 80% in eight weeks.

Chesky had to lay off 1,900 employees — 25% of the company — in a single memo that became famous for how honest it was. He gave everyone 14 weeks of severance and a year of health insurance.

The company burned through its IPO plans and took on $2 billion in emergency debt at brutal interest rates.

But here's the thing — COVID also saved them. People stopped wanting hotel lobbies and started wanting isolated cabins and rural homes.

Airbnb's bookings came roaring back by summer 2020, and the rural/unique stays trend became permanent. They IPO'd in December 2020 at a valuation that stunned everyone.

GitPod

GitHub Codespaces, backed by Microsoft and GitHub's enormous distribution, was a direct competitor, and AWS stopped taking new Cloud9 customers in 2024, a sign of how tough the cloud IDE market was. Convincing developers to give up their carefully configured laptops proved hard.

Then AI coding tools threatened to make the whole category a feature. GitPod's answer was to reinvent itself as Ona, an AI agent platform, and ultimately to sell to OpenAI in 2026 rather than compete alone.

Airbnb Stays is the core product — book someone's home instead of a hotel. Airbnb Experiences lets you book local activities run by hosts, like cooking classes in Rome or surf lessons in Bali.

Airbnb Luxe is the ultra-premium tier — think private islands, castles, and villas with dedicated concierge service. Airbnb Plus, an inspected-homes tier, was wound down in 2023 after proving too costly to verify at scale.

Categories (launched 2022) lets you browse by vibe — treehouses, lakefront, tiny homes, mansions — instead of just searching by location.

GitPod

Before 2025: cloud development environments, instant pre-configured workspaces defined in a .gitpod.yml file, with prebuilds and support for VS Code and JetBrains, plus a self-hosted enterprise option. As Ona (since September 2025): a platform for running software engineering AI agents in secure, sandboxed cloud environments, with VS Code in the browser and access from phone, tablet or laptop.

Since August 2026 the technology is part of OpenAI's Codex team.
