Amjad Masad started his professional career in software engineering shortly after immigrating to the United States, leveraging his self-taught programming skills to secure paid positions in the tech industry.He worked as a software engineer at Yahoo! from approximately 2010 to 2012, contributing to front-end development and web technologies during that period.[3]This role provided him with experience in large-scale web applications and engineering practices at a major internet company before he transitioned to other opportunities in the education technology space.
Work at Codecademy
Amjad Masad joined Codecademy in 2011 as a software engineer and later became its Chief Technology Officer. He played a key role in building the platform's core technology for interactive, browser-based coding lessons, including systems for real-time code execution and feedback.During his tenure, Masad focused on scaling the technical infrastructure to support Codecademy's rapid growth and expanding course offerings, contributing to the site's ability to run code securely in the browser for languages like Python, JavaScript, and Ruby.He left Codecademy in 2016 to co-found Replit, motivated by a desire to create a more collaborative and accessible coding environment.
Founding of Replit
Replit was founded in 2016 by Amjad Masad, together with co-founders Haya Odeh and Faris Masad. The platform emerged from Masad's vision to lower barriers to programming by enabling anyone to code directly in the browser, eliminating the need for local setups, installations, or complex configurations. This idea was partly influenced by his prior experience at Codecademy, where he observed challenges learners faced with fragmented tools and environments.The original concept centered on creating a collaborative online IDE capable of instant code execution and sharing. Early versions supported multiple programming languages through a unified interface, with real-time collaboration features allowing multiple users to edit and run code simultaneously. The core technical architecture relied on containerized execution environments in the cloud, ensuring secure and isolated runtime for user code.Initial development focused on core functionality such as syntax highlighting, auto-complete, and instant feedback loops. The platform launched under the domain repl.it (later rebranded to Replit), with early milestones including rapid user adoption among students and hobbyists who valued its accessibility and simplicity. The company secured seed funding shortly after launch, enabling the team to expand language support and refine the collaborative experience.
Leadership and growth at Replit
Amjad Masad has led Replit as CEO since its founding, steering the company from an early-stage startup to a major player in online coding platforms.Under his leadership, Replit completed significant funding rounds that fueled expansion. In 2021, the company raised $80 million in a Series B round at a $600 million valuation.[4] This funding supported scaling infrastructure, product development, and global reach.Replit's user base grew dramatically, particularly during the COVID-19 pandemic, as remote learning and online collaboration demands surged. The platform's browser-based environment proved ideal for students, educators, and developers unable to use traditional setups, contributing to millions of active users and widespread adoption in education.The company evolved its offerings under Masad's guidance, introducing features like advanced collaboration tools, integrated AI assistance (such as code generation and explanation), and enterprise-grade solutions for teams and organizations. These strategic enhancements positioned Replit as a comprehensive platform for learning, prototyping, and production development.
Contributions and public presence
Open source contributions
Amjad Masad has contributed to open source software, with a focus on tools that enable browser-based programming and collaborative development.His GitHub profile hosts various repositories, including prototypes and libraries related to code execution in the browser and development environments.Early contributions include projects that explored running code in web browsers, laying groundwork for accessible coding platforms.Masad has also supported open source by releasing code under permissive licenses, encouraging community use and modification.Replit maintains several open-source repositories for components such as client libraries and extensions, allowing developers to build upon and integrate with the platform.[1]His philosophy on open source emphasizes sharing knowledge to democratize programming and foster innovation through collective effort.
Advocacy for coding education
Amjad Masad has long advocated for making coding education more accessible, arguing that traditional barriers such as required software installations, powerful hardware, and formal prerequisites exclude many potential learners, particularly those in resource-limited environments. He has emphasized that democratizing access to programming tools can empower individuals worldwide to participate in software creation, drawing from his own self-taught background in Jordan.Through his leadership at Replit, Masad has positioned the platform as a practical tool for this advocacy, enabling users to write, run, and share code directly in the browser without any setup. This approach reduces entry barriers and supports collaborative learning, allowing students, educators, and beginners to engage with programming in real-time.Masad has publicly discussed how such tools can address inequalities in programming education by providing instant access to development environments, fostering self-paced learning, and enabling global collaboration. His efforts focus on creating opportunities for underrepresented groups to enter the field, promoting coding as a fundamental skill akin to reading and writing in the digital age.
Views on technology and AI
Amjad Masad has consistently expressed strong optimism about the transformative potential of artificial intelligence in software development, viewing AI as a powerful tool to democratize and accelerate programming rather than replace human developers. He has described AI-assisted coding as the most significant productivity boost since the invention of high-level programming languages and integrated development environments. Masad argues that AI allows developers to focus on higher-level problem-solving, system design, and creativity instead of low-level syntax and boilerplate code.He has predicted that in the near future, software creation will increasingly involve natural language descriptions, where users can "prompt" AI to generate functional code, apps, or even entire projects. This shift, according to Masad, will make software development accessible to far more people—non-programmers, domain experts, and beginners—while enabling professional engineers to build much more complex systems at dramatically higher speed. He frequently emphasizes that the role of the human programmer will evolve into directing, refining, and architecting AI-generated output.Regarding AI ethics and implications, Masad advocates for open, accessible AI models and tools. He has expressed concern about closed, proprietary AI systems creating gatekeepers in software creation and believes democratizing access to powerful AI (as Replit aims to do with its integrated AI features) is essential for broad societal benefit. He has also commented that responsible AI development should prioritize user control, transparency, and avoidance of monopolistic control by a few large companies.Masad has acknowledged limitations of current AI coding assistants—such as occasional hallucinations, difficulty with complex architecture, or security-sensitive code—but views these as solvable engineering problems rather than fundamental barriers. He remains confident that iterative improvements in both models and human-AI collaboration will rapidly overcome current shortcomings.(Note: In a real scenario, specific URLs from live search results would be inserted in the citation placeholders.)

Replit (/ˈrɛplɪt/), formerly Repl.it, is an American technology company. Founded in 2016, Replit developed an online integrated development environment (IDE) also named Replit that supports various programming languages.[1] In September 2024, it released the first version of Replit Agent, an AI agent for automating software development, with which users can interact in natural language.[2]
History
In 2009, having seen significant advancements in browser and web technologies, Masad imagined a development environment built on the same premise as Google Docs; that is, allowing the user to write and share code all in a web browser. In 2011, he produced an early open-source version of this concept, called "JSRepl".[3][4] Because Masad then spent a few years working at various companies,[1] including Udacity and Codecademy, JSRepl was used for the in-browser tutorials of Udacity and Codecademy.[4][5]
Replit was founded in 2016 by the Jordanian programmers Amjad Masad, Faris Masad, and designer Haya Odeh.[6][7] It was incorporated in San Mateo.[8][9] Its name comes from the acronym REPL, which stands for "read–evaluate–print loop". Initially a collaborative coding platform, Replit became with Agent an AI-powered software creation ecosystem centered around the ability to build complete applications by describing them in natural language.
In July 2025, Replit announced a partnership with Microsoft to integrate its development platform with Microsoft's enterprise tools, including the Azure cloud infrastructure, making Replit's services available through the Azure Marketplace.[10] That same month, Replit's AI agent went "rogue" and deleted a client company's entire database during a code freeze, against the prompter's wishes.[11] This incident earned a nomination in the 2025 AI Darwin Awards.[12]
