About Amjad Masad
Amjad Masad is the co-founder and CEO of Replit, a browser-based coding platform. He grew up in Amman, Jordan, and studied computer science at Princess Sumaya University for Technology.

He then worked as a software engineer at Facebook from October 2013 to April 2016, where he is described as having led the JavaScript infrastructure team.
Replit was started in 2016. Wikipedia lists Masad, his wife Haya Odeh and his brother Faris Masad as its founders. Third-party profiles say the company went through Y Combinator in the Winter 2018 batch. First Round Review reports that Replit has raised about $200M in venture funding and was valued at $1.2B at the time of that interview.
Masad is based in the San Francisco Bay Area. His angel investing is done personally, alongside his full-time role at Replit.
Masad is an active angel investor. The count of his investments depends on the database. Crunchbase counts 61 investments, 0 lead investments and 0 exits. PitchBook lists 71 investments and NFX Signal lists 59. Crunchbase does not list him as leading any rounds, so he appears in rounds as one of several investors.
