The Story

From Internet Cafe to the Cloud

Somewhere in Amman, Jordan, a teenager is walking miles to an internet cafe with a notebook full of half-finished code. He pays for 15 minutes. Types in the missing piece he needed. Walks back. Finishes the program. That teenager was Amjad Masad - and that friction, that specific absurdity of paying by the minute to look up a syntax question, became the founding logic of a $9 billion company.

Masad grew up in a modest household in Amman with Palestinian heritage on his father's side. The family's first computer - an IBM desktop - arrived when he was six years old, bought on loan by his father for work. The machine was off-limits unless his father left the room. So Amjad waited, learned in stolen sessions, and developed a talent for making something from very little.

By 13, he had his first commercial software. Local internet cafes had a security problem: customers were modifying settings, installing junk, leaving machines in bad shape. Masad wrote software to lock them down. He pitched it to a cafe owner, spent two years refining it, and deployed it for real money. His first product was solving his own environment's problems - a pattern that has never left him.

Coding is the closest thing we have to superpowers.

- Amjad Masad

The path to Silicon Valley ran through Princess Sumaya University for Technology in Jordan, where Masad studied computer science between 2005 and 2010. During this time, he was already building in a different direction than his peers - compiling programming languages to run in the browser, a then-exotic idea. By 2011, his work went viral on Hacker News. Brendan Eich, the man who invented JavaScript, publicly acknowledged what Masad had built. That was his resume. He didn't need much else.

Building Replit: The Long Game

Masad arrived in San Francisco from Jordan with debt, no prestigious network, and a product idea that most investors thought was too niche. Replit - a browser-based coding environment that required no installation, no configuration, no 45-minute setup ritual - seemed obvious to anyone who had ever tried to learn to code on borrowed time. To many investors, it seemed too simple.

He applied to Y Combinator four times. Four rejections. On the fourth attempt, his application reportedly included a Rick Roll video rather than a conventional pitch. He eventually got in during the Winter 2018 batch, reportedly after a recommendation pathway involving Paul Graham and Sam Altman. By that point, Replit had already achieved ramen profitability, earning revenue from educators using its API.

The family dimension of Replit is easy to overlook and easy to underestimate. Masad co-founded the company with his wife, Haya Odeh, and his brother Faris. It's not a co-founder dynamic built in a coffee shop between strangers - it's a family building something together, which carries a different kind of durability.

"We don't care about professional coders anymore - we want to empower non-developers to build software using AI."

The inflection point came when Masad stopped building for developers and started building for people with ideas. The professional coder was never really the target - they had their environments, their toolchains, their setups. The real underserved audience was the 13-year-old in Amman paying by the minute, the small business owner who wants a custom app, the domain expert who knows exactly what they need but can't hire an engineering team.

By 2023, Replit integrated AI deeply into the platform under the Ghostwriter brand. By 2024, they had released one of the first commercial AI coding agents - before the term "vibe coding" had even been coined. When Andrej Karpathy popularized the phrase in early 2025, Masad had already built the infrastructure for it. His reaction was characteristically precise: "I don't really like this term. It just cheapens the possibilities."

September 2025: $250 million raised at a $3 billion valuation. March 2026: $400 million Series D at $9 billion - led by Georgian Partners, with participation from Andreessen Horowitz, Coatue, Y Combinator, and a roster of angels that included Shaquille O'Neal and Jared Leto. The same round that made Masad a billionaire also launched Agent 4, a product that can build a full startup - pitch deck, animated logo, Stripe integration, the works - from a plain English description.

Replit's stated target: $1 billion in ARR by end of 2026. For a platform that hit $150 million annualized revenue ahead of the Series D, that number is ambitious. Masad frames it as the natural consequence of a platform shift - not from IDE to better IDE, but from "coding tool" to "business launch control."

Ideas & Beliefs

How He Thinks

On the billion-creator future

Masad's central conviction is that AI doesn't eliminate software engineers - it creates them by the billions. Traditional coding training was a bottleneck, not a ceiling. Remove the bottleneck, and you discover how many people always wanted to build things but couldn't navigate the setup friction.

On "vibe coding"

"I don't really like this term. It just cheapens the possibilities." Masad has been building the infrastructure for AI-assisted coding since before the phrase existed. His objection isn't to the workflow - it's to the framing, which implies casualness where he sees something fundamental.

On speed and decision-making

Ship daily. Good decisions today beat perfect decisions delayed indefinitely. A startup's primary competitive advantage over established companies is velocity - and Masad treats that as infrastructure, not just attitude. Replit has shipped continuously across every market shift.

On talent and opportunity

Talent is globally distributed. Opportunity is not - yet. Masad's entire career has been a systematic attack on that gap. From the internet cafe to Codecademy to Replit's AI agents, the through-line is always: remove the barrier between the person with the idea and the thing they want to build.

The future of programming is about having ideas and bringing them to life. When setup friction disappears, you discover how many people have been waiting to build something.

- Amjad Masad

Quotable Masad

Our goal is to bring the next billion software creators online.

Prompting is programming without brackets.

Replit is the cockpit or the launch control of your business.

Do what makes the best story.

AI is like a brilliant but easily distracted intern - it requires precise direction.

We're going to have a billion software engineers, and we're actually all going to have jobs - they're just going to be very powerful.

The Details

Fun Facts & Footnotes

01
Replit was co-founded on April 1, 2016. Yes, April Fool's Day. The company that wants to make coding universally accessible launched as a prank-adjacent date.
02
His Twitter/X handle is @amasad - not @amjadmasad. He describes himself in his bio as a "civilizationist" - a word that's doing some heavy philosophical lifting.
03
Angel investors in Replit's $400M Series D round included Shaquille O'Neal and Jared Leto. Not the typical cap table for a developer tools company.
04
His YC application included a Rick Roll video. He was rejected three times before that. The fourth attempt - unconventional application included - eventually got him in.
05
Masad co-founded Replit with his wife Haya Odeh and his brother Faris. Three family members, one startup. The family unit runs the company to this day.
06
In 2011, Brendan Eich - the man who created JavaScript - publicly praised Masad's work on Hacker News. That was essentially his Silicon Valley job application.
