At dYdX, he led development of the platform’s core trading product during a period of growth for decentralized perpetual futures markets. In 2024, Park co-founded Fomo, where he has focused on building products for cryptocurrency users and traders. As co-founder, he oversees the company's strategy, product development, and growth initiatives within the digital asset ecosystem. ^[1]

Fomo

Fomo is a cryptocurrency trading and discovery platform that simplifies access to digital assets for mobile users. Built initially around the Solana ecosystem, the platform combines trading functionality, social features, and market discovery tools to reduce the technical barriers commonly associated with entering cryptocurrency markets.

The platform allows users to create accounts using familiar consumer onboarding methods and purchase digital assets through integrated payment options. In addition to trading capabilities, Fomo incorporates social and informational features that enable users to monitor market activity, track other traders' transactions, receive real-time notifications, and view discussions about individual assets. The platform also provides tools for tracking portfolio performance, identifying trending assets, and summarizing market activity.

Fomo positions trading as a more interactive and transparent experience by incorporating elements commonly found in social media applications. Rather than focusing solely on transaction execution, the platform emphasizes visibility into trading activity and performance metrics, allowing users to observe market behavior and engage with information generated by other participants. Since its launch, Fomo has expanded its user base through its mobile-first approach and has outlined plans to support additional blockchain ecosystems beyond Solana. ^{[2] [4]}

Interviews

Building Fomo

In a June 2026 interview with Ash Robin, Park discussed Fomo’s early traction and its positioning within the onchain trading landscape. He noted that Fomo had raised approximately $85 million within its first year of operation and grown to more than 600,000 users, reflecting strong early adoption and interest in its social trading model. Park described this growth as evidence of demand for platforms that combine execution tools with community-driven discovery and performance visibility. He also emphasized that Fomo’s approach centers on integrating trading activity with social interaction rather than treating them as separate experiences.

Park explained that Fomo was designed to merge trading functionality with a social layer, allowing users to share strategies, follow other traders, and track performance through features such as leaderboards and wallet activity. He highlighted the platform’s emphasis on transparency, social proof, and community engagement as key drivers of user participation, while noting that trading outcomes ultimately remain dependent on skill and asset selection. Park also described Fomo’s broader ambition to reduce friction in accessing onchain markets, including spot and perpetual futures trading. He suggested that social and informational layers will play an increasingly important role in the evolution of digital asset trading and the way users interact with financial markets. ^[5]

Trade Like a Founder

On the In the Trenches podcast in June 2026, Park shared his trading journey, beginning in 2021 with Avalanche, where he initially followed luck rather than skill by investing in early DeFi projects like Time, which taught him the importance of being early and finding opportunities. He reflected on his progression from traditional trading experiences, such as trading IPOs on Robinhood, to developing more intuitive, fundamental-based decision-making rather than relying solely on technical analysis. Park emphasized the significance of gut instincts, product usability, and an understanding of market sentiment, especially through social signals, in crafting durable narratives. His time working at dYdX provided insights into building successful perpetual exchange products and understanding user needs, though he remained cautious about shorting and leverage, advocating for protective risk management. Park highlighted the importance of patience, discipline, and self-awareness, such as journaling, to prevent emotional trading mistakes like round-tripping profits. He recounted his most memorable wins, like trading the token GME on Solana, which allowed him to enjoy real-life experiences, and acknowledged his tendency to hold too long, often riding winners to the top. Park stressed that trading is a lifelong, competitive game driven by temperament and conviction, with community learning and adaptability as critical edges. Ultimately, he expressed a commitment to trading forever, viewing it as a perpetual contest of skill, belief, and continuous evolution. ^[7]

User-Friendly Trading

On The Archive podcast in April 2026, Park reflected on the challenges of onboarding mainstream users to crypto, recognizing that crypto platforms have historically catered mainly to crypto enthusiasts and that this barrier has hindered broader adoption. After gaining experience at dYdX, where he transitioned from business development to product management, he emphasized the importance of creating intuitive, user-centric products that prioritize a smooth user experience and community engagement. In late 2024, Park co-founded Fomo to address crypto's onboarding challenges, focusing on developing a simple, social, multi-chain trading app tailored for both expert traders and absolute newcomers. The team prioritized rapid iteration, organic growth, and trust-building through transparency, while avoiding traditional marketing approaches. They established a lean, high-integrity team that initially worked without pay, emphasizing product quality and user feedback. Major growth episodes stemmed from key product innovations such as multi-chain support, seamless cross-chain trading, and easy on-ramps like Apple Pay, which significantly lowered entry barriers. Park highlighted the importance of organic, user-led marketing and the potential of social features to foster network effects. Looking ahead, he envisioned Fomo evolving into a comprehensive platform that combines crypto trading, social interaction, and behavioral indicators like accuracy and credibility, aiming to make all of crypto feel almost frictionless and intuitive—much like social media shifted from connection-based to interest-driven models. Throughout, Park underscored the value of maintaining a focused, high-quality product that prioritizes long-term, sustainable growth over rapid scaling, drawing lessons from successful crypto-native companies and industry standards to build a trusted, user-centric ecosystem ^[6]
