Block (Square)

Block makes money across several business lines. Square (the seller ecosystem) charges merchants a flat percentage per transaction — 2.6% + $0.10 for in-person payments, higher for online.

Cash App takes a fee on instant deposits, Bitcoin trading, and Cash App Pay transactions. Afterpay (announced at $29 billion in 2021, though Block's share price fell so far before closing in January 2022 that the final price was closer to $14 billion) earns merchant fees on buy-now-pay-later transactions.

TIDAL is the music streaming service (acquired from Jay-Z). Block also earns Bitcoin revenue — Cash App is one of the largest Bitcoin brokers in the US, though margins on BTC trading are razor-thin.

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.

The origin story starts with Jim McKelvey, a glass blower in St. Louis and old friend of Jack Dorsey.

In 2009, McKelvey lost a $2,000 sale on a glass faucet because he couldn't accept credit cards. The customer wanted to pay with Amex.

McKelvey couldn't process it. The sale fell through.

McKelvey called Dorsey, who had been pushed out of the Twitter CEO job the year before and was serving as its chairman, and they started brainstorming. The problem was obvious: millions of small businesses, street vendors, farmers market sellers, and independent contractors couldn't accept credit cards because merchant accounts required monthly fees, credit checks, and clunky hardware that cost hundreds of dollars.

Dorsey and McKelvey wanted to make it so anyone could accept a credit card using just their phone.

They built a tiny white card reader that plugged into a smartphone's headphone jack. The reader cost almost nothing to manufacture and Square gave it away for free.

The software was simple — swipe the card, enter the amount, the customer signs on the screen, done. Square charged a flat 2.75% per transaction with no monthly fees, no contracts, and no minimums.

The product launched in 2010 and spread through small businesses like wildfire.

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.

Square grew by giving away the hardware. The card reader was free.

That eliminated the biggest barrier for small businesses. A food truck operator, a yoga instructor, a farmers market vendor — anyone could start accepting cards in five minutes without spending a dollar upfront.

Square made its money on the transaction fees that followed.

The simplicity was the pitch. Traditional merchant services involved contracts, monthly minimums, tiered pricing, and hidden fees that required a finance degree to understand.

Square charged one flat rate for everything. No surprises.

That transparency built enormous trust with small business owners who had been burned by traditional processors.

Cash App grew through peer-to-peer payments and a brilliant viral strategy. The app launched in 2013 as a simple way to send money to friends.

Rappers, influencers, and content creators started using their $cashtag for tips and payments. Cash App sponsored hip-hop events and partnered with musicians.

By 2024, Cash App had over 55 million monthly active users — more than most banks.

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.

The Afterpay acquisition was controversial. Announced at $29 billion in 2021, it closed in January 2022 at roughly half that after Block's own stock fell.

Buy-now-pay-later was already facing regulatory scrutiny and growing delinquency rates. Critics argued Dorsey overpaid at the peak of the market.

Afterpay's revenue growth slowed significantly after the acquisition, and write-offs on bad consumer debt increased. It remains the biggest bet Block has ever made.

The Bitcoin obsession worries investors. After renaming Square to Block in December 2021, Dorsey went all-in on Bitcoin — investing company cash in BTC, building Bitcoin mining hardware, and creating TBD (a Bitcoin-focused developer platform).

While Cash App's Bitcoin revenue is huge on paper ($10+ billion annually), the margins are tiny. Investors question whether the Bitcoin focus distracts from the core payments business.

Competition is intense on every front. Square competes with Stripe, Toast, and Clover for merchants.

Cash App competes with Venmo, Zelle, and Apple Pay for consumers. Afterpay competes with Klarna, Affirm, and bank-native BNPL products.

Block has to fight multiple wars simultaneously with finite resources.

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.

Square is the merchant ecosystem — point-of-sale hardware, payment processing, invoicing, payroll, loans, and online stores for businesses of all sizes. Cash App is the consumer side — peer-to-peer payments, direct deposit, investing, Bitcoin buying, and the Cash App Card (a debit card).

Afterpay is the buy-now-pay-later product — split any purchase into four interest-free payments. Square Banking offers business checking accounts and loans.

Square Online lets merchants build e-commerce websites. TIDAL is the music streaming platform that pays artists higher royalties.

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.
