About Karim Atiyeh
Karim Atiyeh is based in New York. He is a co-founder of Ramp, the corporate card and spend management company. He holds a BA in Electrical and Computer Engineering and an MS in Computer Science from Harvard University, according to Ramp's author page.
Before Ramp, he co-founded Paribus, a Y Combinator-backed app that tracked prices to help consumers save on online purchases. Paribus was acquired by Capital One in 2016. Atiyeh and Eric Glyman, his co-founder at both companies, met as classmates at Harvard.
Ramp was founded in March 2019 by Glyman, Atiyeh and Gene Lee, and launched in February 2020. Atiyeh served as chief technology officer. Crunchbase now lists him as Co-CEO, with that role dated June 2026.
The Crunchbase profile referenced by Lounge shows 38 investments, with no lead investments, no exits and no companies founded. A separate Crunchbase profile for Atiyeh, listed under his Ramp role, shows 65 investments and 62 portfolio companies. Tracxn counts a smaller number, 17 companies, so totals differ by source.
Crunchbase's investor timeline shows him in rounds as early as 2021 and 2022, including Eight Sleep, Archive, Pomelo, Modal Labs, Float and Weav. Tracxn lists Pomelo and Archive among his most notable investments.
Press and company announcements usually list him as a participating angel. None of the sources reviewed identifies him as a lead investor, which matches the zero lead investments on Crunchbase.
Crunchbase data cited by Lounge shows 22 AI investments since 2023. The AI portfolio includes Capsule, Natural, LGND, 1001 AI, Miravoice, Monogram, Beacon Holdings, Prime Intellect, Cognition, Paradigm, Console and Augustus.
