Robinhood

Robinhood makes money in ways that don't involve charging users directly. The biggest revenue source is payment for order flow (PFOF) — when users place a trade, Robinhood routes it to market makers like Citadel Securities, who pay Robinhood for the right to execute the trade.

This generates hundreds of millions annually. Robinhood also earns interest on uninvested cash sitting in user accounts, margin lending (charging interest when users borrow money to trade), and Robinhood Gold — a $5/month subscription for larger instant deposits, professional research, and higher interest on cash.

Magic AI

Magic is building an AI that works like a software engineer, not a chatbot. The goal is a model you can hand a whole code base and a task, and it writes, reviews, and debugs like a teammate.

Their edge is memory. In 2024 they showed off LTM-2-mini, a model with a 100 million token context window.

To put that in perspective, that is about 10 million lines of code the model can look at in one shot, by far the biggest of any model at the time. The plan is to sell this as an AI coworker to companies that write a lot of software.

As of the 2024 rounds, the product was still not for sale.

Robinhood

Vlad Tenev and Baiju Bhatt met as physics and math students at Stanford. After graduating, they moved to New York and started two fintech companies that sold trading software to hedge funds.

While building tools for Wall Street, they noticed something absurd: it cost brokerages essentially nothing to execute a trade electronically, but they were charging retail investors $7-10 per trade.

The math was simple. Electronic trading had driven costs to near zero, but brokerages kept the old pricing because customers didn't know better.

Tenev and Bhatt thought: what if we just charged zero? In 2013, they founded Robinhood with the explicit mission of democratizing finance — giving everyone access to the stock market with no commissions, no minimums, and a beautiful mobile app.

The app launched in 2014 with a waitlist that hit 1 million people before the product was even available. The pink-and-green design, the confetti animation when you made a trade, and the simplicity of the interface made investing feel approachable.

For millions of young Americans who had never bought a stock, Robinhood was the entry point.

Eric Steinberger and Sebastian De Ro started Magic in 2022. Steinberger is an AI researcher who became convinced that the missing piece for a true AI software engineer was memory.

Chatbots forget what you told them a few thousand words ago. He wanted a model that could read your entire code base and remember all of it.

They raised a small seed in 2022, then a $23 million Series A in early 2023 led by Alphabet's growth fund CapitalG. From day one the pitch was not a chatbot.

It was an AI colleague that could handle real engineering work.

Robinhood

Robinhood grew by making investing feel like a game. The app was designed to be addictive — swipe to trade, confetti for your first purchase, notifications about stock movements.

It was investing designed for the smartphone generation. Critics called it "gamification of finance." Users called it the first trading app that didn't feel like it was designed in 1997.

The referral program was massive. Both the referer and the new user got a free stock when someone signed up.

People were getting free shares of Apple or Ford just for downloading the app. It spread through college campuses like wildfire.

By 2020, the average Robinhood user was 31 years old — decades younger than the average brokerage customer.

Zero commissions forced the entire industry to follow. In October 2019, Charles Schwab, TD Ameritrade, E-Trade, and Fidelity all dropped their trading commissions to zero within days of each other.

Robinhood had single-handedly destroyed the commission-based brokerage model that had existed for decades.

Magic AI

Magic's strategy is research first, product later, which is both unusual and expensive. Instead of shipping an app and iterating in public, they raised huge sums to chase a technical breakthrough in model memory.

The headline move was the 100 million token context claim, which got the whole AI world talking. They also cut a deal with Google Cloud in 2024 to build two supercomputers, called Magic-G4 and Magic-G5, using NVIDIA chips, to train bigger models.

Star backers like Eric Schmidt served as validation. The bet is that if the tech is far enough ahead, the product and the customers follow.

Robinhood

GameStop was the worst week in Robinhood's history. In January 2021, Reddit's r/WallStreetBets community drove GameStop stock from $20 to $483.

Millions of Robinhood users were buying. Then on January 28, Robinhood restricted buying of GameStop and several other meme stocks.

Users could only sell, not buy. The stock crashed.

The backlash was nuclear. Users accused Robinhood of siding with hedge funds against retail investors.

Vlad Tenev was dragged before Congress. The real reason was less sinister but equally damaging — Robinhood's clearinghouse (DTCC) demanded $3 billion in additional collateral due to the extreme volatility, and Robinhood didn't have it.

They had to raise $3.4 billion in emergency funding over a weekend. The company that built its brand on democratizing finance had restricted the most democratic stock trade in history.

The payment for order flow controversy never goes away. Critics argue that PFOF creates a conflict of interest — Robinhood profits by routing user trades to market makers rather than getting users the best possible price.

The SEC has considered banning PFOF entirely. If that happens, Robinhood loses its largest revenue source.

Post-IPO performance was brutal. Robinhood went public in July 2021 at $38 per share.

The stock briefly hit $70 on meme stock momentum, then cratered to under $8 by mid-2022 — a 90% decline. The company laid off 9% of staff in April 2022 and another 23% that August.

Magic AI

Magic has raised close to half a billion dollars and, years in, still has no product the public can buy. That is the whole problem in one sentence.

A giant context window is a great demo, but rivals like Cursor, GitHub Copilot, and Cognition's Devin already have real users and revenue. Magic has to prove that more memory actually makes a smarter engineer, not just a bigger number on a slide.

And it has to do that while burning enormous sums on compute against competitors who are already shipping. The clock and the cash both keep running.

Robinhood

Robinhood is a stock, options, and crypto trading app. The core product lets you buy and sell stocks, ETFs, and options with zero commissions.

Robinhood Crypto adds trading for Bitcoin, Ethereum, and other cryptocurrencies. Robinhood Gold is the premium tier — higher interest on cash, larger instant deposits, and Morningstar research reports.

Robinhood Cash Card is a debit card that earns cashback and rounds up purchases to invest spare change. Robinhood Retirement offers IRA accounts with a 1% match on contributions.

Robinhood Legend is their new desktop trading platform aimed at active traders.

Magic AI

The centerpiece is Magic's LTM, or Long-Term Memory, model family. In 2024 they unveiled LTM-2-mini, a model with a 100 million token context window, pitched as the key to an AI that can understand an entire code base at once.

The broader product is an AI software engineer, or coworker, that can write and change code across a whole project. The company also announced Magic-G4 and Magic-G5, two supercomputers built with Google Cloud and NVIDIA to train these models.

Much of it is still research rather than a shipping product.

Magic AI

Magic's backers are a murderers' row of AI insiders. It started with a $5 million seed round in 2022 and a $23 million Series A in early 2023 led by Alphabet's CapitalG.

Then in February 2024 came a $117 million round led by Nat Friedman and Daniel Gross, two of the most connected investors in AI. The blowout was August 2024.

Magic raised $320 million with checks from former Google CEO Eric Schmidt, CapitalG again, Atlassian, Jane Street, Sequoia, and Elad Gil. That pushed total funding to around $465 million, all for a company still building toward its first sellable product.
