Replit

Replit originated in a browser-based programming project that Masad developed in 2011 to let people run code without first installing complicated environments. In 2015, he and designer Haya Odeh rebuilt the project. Faris Masad joined the early engineering work, adding account systems and cloud execution.⁠[1]

The company was incorporated in May 2016 and launched Classroom for teachers in August, supporting assignment distribution, monitoring of student progress and feedback. Education and general developer use jointly shaped its early product direction.⁠[1]

Replit announced an $80 million Series B to expand its programming environment, community and cloud infrastructure. It also announced support for open-source projects including FreeCodeCamp and the Nix Foundation, and identified databases, authentication and computing as areas for further development.⁠[2]

Replit raised $97.4 million at a $1.16 billion post-money valuation in a round led by a16zAndreessen HorowitzAndreessen Horowitz (a16z) is a venture capital firm founded in 2009 by Marc Andreessen and Ben Horowitz.

Its products then included a cloud development environment, multiplayer collaboration, mobile development and Ghostwriter. Ghostwriter supplied code completion and chat informed by project files and context. Funding was intended to expand cloud services and AI development tools.⁠[3]

The company shifted its research and development focus toward AI agents in 2024. In a later interview, Masad said the May layoffs were partly intended to reduce spending and focus its product direction. He believed improving model capabilities that year had made generating complete applications more feasible.⁠[4]

In September, an early version of Replit Agent became available to Core subscribers, configuring environments, installing dependencies, and writing and running code from natural-language requests. On December 10, Agent left early access, and the company introduced Assistant for modifying existing projects.⁠[5][6]

In July, while Jason LemkinJason LemkinFounder of SaaStr.Open the full entry was building an application with Replit, Agent deleted data in a production database during development. Masad confirmed the incident on July 20, offered assistance and a refund, and committed to reviewing what happened. He also advanced separate development and production databases and a planning mode that did not modify code. The affected data was subsequently recovered.⁠[7][8]

On July 21, Replit began rolling out a beta feature separating development and production databases for new applications. A first deployment could create a separate production database; subsequent changes occurred in the development database, with the system asking whether schema changes should be applied to production on redeployment. Automatic migration for existing applications was scheduled for later.⁠[9]

Replit raised $250 million at a $3 billion valuation in a round led by Prysm Capital, with Amex Ventures, GoogleGoogleGoogle is an American technology company founded by Larry Page and Sergey Brin and incorporated in 1998.

The integration between Replit and Databricks became generally available, adding native support for Lakebase. Users could create applications in Replit and deploy them under Databricks’ data permissions and governance framework. Additions included preview deployments, automatic database configuration and team approval before database changes went live.⁠[13]

Masad announced Replit’s acquisition of Test13, describing it as a company built entirely using Replit. The transaction brought a software business created by a platform user into Replit.⁠[14]

On November 4, 2026, Replit announced its first Asian office in Tokyo, following its London opening in September. It also expanded its partnership with Sumitomo Mitsui Finance and Leasing Company (SMFL) to bring its development platform to more Asian enterprises.
