Abdur Chowdhury

Abdur Chowdhury is a pioneering technology entrepreneur and angel investor with over 30 years of experience building transformative internet products. He is currently the Co-Founder and CEO of Aura Frames, a digital photo frame company he founded in 2012 with former Twitter colleague Eric Jensen. Aura has raised $46.9 million across 8 funding rounds, achieved profitability in 2024, and serves over 6 million app users with nearly 1 million frames sold.

Chowdhury earned his BS and MS degrees in Computer Science from George Mason University and his PhD from the Illinois Institute of Technology. After completing his doctorate, he taught briefly at Georgetown University. In 2010, he co-founded Alta Vista, an independent elementary school in San Mateo, California, that pioneered the STEAM concept (science, technology, engineering, arts, and math), demonstrating his commitment to education and innovation beyond his entrepreneurial pursuits.

His career trajectory includes serving as Chief Architect for Search at AOL from May 2000 to August 2006, where he led major innovations in search technology. In August 2006, he co-founded Summize, a real-time search engine that pioneered organizing real-time opinions on the internet by crawling blogs, YouTube, and other social platforms to identify trends and popular content. Twitter acquired Summize in 2008 for approximately $15 million in cash and stock, and Chowdhury became Twitter's first Chief Scientist. During his tenure at Twitter from 2008 to 2011, he built and led the Search, Analytics, Trends, and User Discovery teams, implementing foundational features that became core to Twitter's platform. When he departed during the 2011 exodus of original Twitter leadership, the company had grown to approximately 950 employees.

Throughout his 30+ year career, Chowdhury has launched over 25 commercial products, holds over 50 patents in search and information retrieval technologies, and has established himself as a thought leader in real-time data, machine learning, and consumer internet products. His work has fundamentally shaped how people discover and interact with information online.

As an angel investor, Abdur Chowdhury focuses on early-stage technology startups, particularly those in consumer internet, media, and hardware. His investment approach is highly selective, having made only 4 known investments since 2014, suggesting he invests strategically in companies where he can provide meaningful value beyond capital.
