## Career
Petersen's career, as he reports it, began at Ekundu Capital, where he served as Principal from January 2022 to January 2024.[4](https://www.linkedin.com/in/robbie-petersen-98a400208) He then spent about fourteen months as a researcher at Delphi Digital, which Crypto Briefing describes as "one of the industry's more respected independent research shops"; his work there centered on analyzing crypto projects and market trends.[2](https://cryptobriefing.com/robbie-petersen-joins-a16z-crypto/) • [3](https://outposts.io/article/dragonfly-adds-robbie-petersen-as-junior-partner-9ab87407-6d03-4b6b-8889-392b1eda640f)
In March 2025 [Dragonfly](https://www.edgepedia.org/dragonfly) appointed Petersen to its investment team as a Junior Partner, a role focused on supporting early-stage founders building in finance and blockchain.[3](https://outposts.io/article/dragonfly-adds-robbie-petersen-as-junior-partner-9ab87407-6d03-4b6b-8889-392b1eda640f) • [4](https://www.linkedin.com/in/robbie-petersen-98a400208) He wrote publicly that discussions about joining the Dragonfly partnership with managing partner [Haseeb Qureshi](https://www.edgepedia.org/haseeb-qureshi) had begun almost four years earlier, alongside partners Bo (Feng Bo) and [Tom Schmidt](https://www.edgepedia.org/tom-schmidt).[5](https://tweetlook.com/robbiepetersen_) His departure post in June 2026 thanked Qureshi, Schmidt, and Michael Hadick, saying "very few places have fostered a culture that embraces independent thought like Dragonfly".[5](https://tweetlook.com/robbiepetersen_)
His education is self-reported: dropping out of [McGill University](https://www.edgepedia.org/mcgill-university).[4](https://www.linkedin.com/in/robbie-petersen-98a400208) No independent source in the record verifies these details.
## Dragonfly Ventures and Fund IV
In February 2026 the firm announced its oversubscribed $650 million fourth fund; Petersen co-announced the raise.[5](https://tweetlook.com/robbiepetersen_) In the announcement he cited the firm's recent bets as [Polymarket](https://www.edgepedia.org/polymarket), Ethena, Rain, and Mesh, arguing that stablecoins, DeFi, and prediction markets are expanding crypto's surface area.[5](https://tweetlook.com/robbiepetersen_)
The record does not name specific deals Petersen personally sourced or led at Dragonfly, nor any exits from his investments with disclosed amounts; the cited portfolio companies are firm-level bets from the Fund IV announcement rather than individual attribution to him.[5](https://tweetlook.com/robbiepetersen_)
## Investment theses and public positions
[Agentic commerce](https://www.edgepedia.org/agentic-commerce) was Petersen's stated niche at Dragonfly: autonomous AI agents transacting on behalf of users, AI-native payments (financial rails for machine-to-machine transactions), and broader crypto infrastructure.[2](https://cryptobriefing.com/robbie-petersen-joins-a16z-crypto/)
In his own posts he set out a payments thesis: the largest fintech opportunity is using stablecoin virtual accounts combined with cards to run the Ramp playbook globally. He noted that Ramp is valued at $32 billion with an entirely US-based business, and argued that owning the card layer captures interchange revenue with high switching costs.[5](https://tweetlook.com/robbiepetersen_)
