Amjad Masad

Background

Amjad Masad is a Jordanian-American entrepreneur and software engineer, born and raised in Amman, Jordan, in a family with Palestinian heritage ¹. His father was a civil engineer from a Palestinian refugee background ¹. Masad began programming at age 12 using Visual Basic and graduated with a B.S. in Computer Science from Princess Sumaya University for Technology in Jordan ².

In 2011, at age 23, Masad immigrated to the United States ¹. He joined Codecademy as employee #1 and founding engineer (November 2011 to October 2013), handling tech leadership, product, and infrastructure ². He then worked as a software engineer at Facebook (October 2013 to April 2016), where he was tech lead on the JavaScript infrastructure team, helping build and maintain open-source tools including the Babel.js compiler, Jest, and the React Native packager ². He also had a brief earlier stint at Yahoo ².

In 2016, Masad co-founded Replit with Haya Odeh and Faris Masad ¹. Replit is an online collaborative coding platform that aims to “bring the next billion software creators online” ². In March 2026, Replit raised a $400M Series D at a $9B valuation, led by Georgian Partners, making Masad a billionaire worth an estimated $2B according to Forbes ³. The company reports $150M in annual recurring revenue and 50 million users ³.

Alongside running Replit, Masad is an active angel investor with approximately 60+ investments according to aggregator databases ⁴.

Stated Thesis

Masad has not published a formal angel investment thesis, but his public statements reveal a consistent worldview that shapes his investing. He believes software costs are falling rapidly and small teams — even solo founders — can build what once required entire companies.

On Twitter/X, he stated: “I expect $1B solo founder startups to become normal pretty soon” ⁵, reflecting his belief in AI-enabled democratization of software development.

In a 2023 interview, Masad described his outlook: “There’s overwhelming opportunity for growth, for Replit, my investments and influence, my contribution to the world” and emphasized that “one of the main things that sets people apart in terms of outcomes in life, in my opinion, is ability to detect opportunity” ⁶.

When announcing his investment in Synthesis, an education company, he wrote: “I can’t think of two higher leverage ways to move society forward,” framing his investing around backing ventures with outsized potential to reshape how people develop talent and solve problems ⁷.

On developer tools specifically, when investing in RunPod, Masad stated: “The ability to create and deploy AI applications at scale will be paramount to their adoption and utilization. The RunPod team has clearly prioritized the developer experience to create an elegant solution that enables individuals to rapidly develop custom AI apps or integrations while also paving the way for organizations to truly deliver on the promise of AI” ⁸.

Masad has also publicly stated he values high-agency, unconventional people. In a Vanta interview, he said: “High agency people tend to be misfits because otherwise you’re going to get…the usual corporate drone” and “You should be open to people who are awkward. You should be open to people who are dropouts” ⁹.

Inferred Thesis

Based on 21 verified investments compiled from press releases, funding announcements, and company blogs. Aggregator databases indicate Masad may have made 60+ total investments ⁴; this analysis covers approximately 35% of his estimated total.

Sector distribution (21 verified investments): - AI / machine learning tools and infrastructure: 10 of 21 (48%) — Perplexity, Contextual AI, Etched, Extropic, RunPod, Roboflow, LiveKit, Vocode, Raindrop, 1001 AI - Developer tools / software infrastructure: 5 of 21 (24%) — Runway, Socket, Mastra, Anon, Tsuga - Media creation / AI content: 2 of 21 (10%) — Synthesia, EzDubs - Social / consumer: 2 of 21 (10%) — Bluesky, Wabi - Education: 1 of 21 (5%) — MagicSchool - Productivity: 1 of 21 (5%) — Granola

Note: Some companies span multiple categories; each is counted once in its primary category. Several companies appear on aggregator databases ⁴ (Replicate, Capsule, Quadratic, MatX, AvatarOS, New Lantern, Portola, GitStart, XBOW, Wefunder, Basis, Cartwheel) but could not be independently verified through primary sources at this time.

Stage distribution (21 verified investments): - Seed / Pre-seed: 14 of 21 (67%) — Perplexity, Contextual AI, Extropic, Bluesky, Vocode, Anon, EzDubs, Tsuga, 1001 AI, Raindrop, Mastra, Wabi (pre-seed), RunPod, MagicSchool - Series A: 2 of 21 (10%) — Etched, LiveKit - Series B: 3 of 21 (14%) — Roboflow, Socket, Granola - Series C: 2 of 21 (10%) — Synthesia, Runway

Geographic patterns: Predominantly US-based companies. International investments include Synthesia (London, UK), Tsuga (Paris, France), 1001 AI (London/Dubai), and Granola (London, UK). Approximately 17 of 21 (81%) are US-based.

Check size: Reported as $5K-$50K with a sweet spot of $25K ¹⁰, consistent with small angel checks. However, Masad participates in rounds ranging from small seeds to $120M later-stage rounds.

Co-investor patterns: Masad frequently co-invests with Guillermo Rauch (CEO of Vercel), appearing together in at least 3 verified rounds (Runway, LiveKit, Mastra). Other repeat co-investors include Elad Gil (Contextual AI, LiveKit, Socket), Balaji Srinivasan (Extropic, Mastra), and Garry Tan (Wabi, Extropic).

Founder profile preferences: Masad backs technical founders building infrastructure-level products. Several portfolio companies have deep AI research backgrounds (Perplexity, Extropic, Contextual AI). He also backs founder-CEOs from peer companies in the developer/AI ecosystem.

Notable pattern: Masad’s portfolio is overwhelmingly AI-focused — 48% pure AI/ML plus additional AI-adjacent investments in developer tools and media creation. His stated thesis about software costs falling and solo founders building billion-dollar companies is directly reflected in his portfolio, which bets heavily on AI infrastructure and tools that enable this vision.

Notable gap: Despite his background in education (Codecademy founding engineer, investing in MagicSchool and Synthesis), edtech represents only 5% of his verified portfolio. His investing is much more concentrated in AI infrastructure than his public statements about democratizing software might suggest.

Exits: EzDubs was acquired by Cisco in November 2025 ¹¹.

Additional companies listed on aggregator databases (Replicate, Capsule, Quadratic, MatX, AvatarOS, New Lantern, Portola, GitStart, XBOW, Wefunder, Basis, Cartwheel) could not be independently verified through primary sources at this time.

What Founders Say

No independently sourced founder testimonials found. Dedicated searches for founder reviews, testimonials, and public statements about Masad as an angel investor did not yield results. Paul Graham, co-founder of Y Combinator, has commented on Masad as a founder: “What struck me most about him, at first, was that he was a programmers’ programmer” ¹, but this refers to Masad as an entrepreneur rather than as an investor.
