About
Prashan Dharmasena is the engineering co-founder of fomo, the social-first crypto trading app valued at $550 million in a $75 million Series B led by Index Ventures in June 2026 — and the person who built the iOS and Android apps that valuation rests on. He spent close to a decade shipping consumer mobile at scale before crypto: an Android intern turned engineer at Fitbit, then five years as a senior Android engineer at Square, then head of mobile at OpenSea from 2022, where he was the primary contributor to its open-source Jellyfish library. He joined dYdX in 2024 to run mobile and frontend platform, and left the same year to start fomo with Paul Erlanger and Se Yong Park. He studied computer science at UC Berkeley, and got his first startup job as a mobile intern at Lockitron in Y Combinator's summer 2013 batch.
Beyond investing
- Founded
- Co-founded fomo in 2024 with Paul Erlanger and Se Yong Park, all three out of dYdX; the app launched publicly in May 2025.
- More
- Ran mobile and frontend platform at dYdX in 2024, leading engineering and product for its web and mobile clients. Head of mobile at OpenSea from 2022 to 2024 and the primary contributor to Jellyfish, OpenSea's open-source mobile library. Senior Android engineer at Square from 2017 to 2022. Started in consumer hardware software at Fitbit — an Android engineering intern in 2015, an R&D intern in 2016 and then a full-time Android engineer. First startup role was as a mobile engineering intern at Lockitron, a Y Combinator summer 2013 company, in 2014. Earned a BA in computer science from UC Berkeley, graduating in 2016. Builds for a bar the founders set publicly: onboard, fund an account and buy a token in about 30 seconds, on a team that was still only 17 people at the Series B while adding roughly 3,500 users a day.
