At just 20 years old, Elijah Popowitz is quickly emerging as one of the most exciting young entrepreneurs to watch in the tech and startup world. Best known for co-founding Offsides, a cutting-edge sports gaming company, Popowitz already boasts a multimillion-dollar exit to his name after the company was acquired by SmackTok, a leading force in sports media and entertainment. Now serving as Chief Strategy Officer at SmackTok, Elijah is leveraging his early success and experience to build his next big venture: Neptune, a revolutionary property technology startup aimed at reshaping the way people rent and manage real estate.
Elijah’s journey began at the Geffen Academy at UCLA, an academically rigorous environment where he first developed his passion for entrepreneurship and leadership. Surrounded by innovation in Los Angeles, Elijah started thinking about how emerging technologies could reshape industries that hadn’t yet caught up to the digital era.
That drive led to the creation of Offsides, a platform built at the intersection of sports fandom and interactive gaming. Unlike traditional sports betting or fantasy leagues, Offsides focused on making live sports more engaging for younger audiences, turning every play into an interactive, social experience. The startup gained significant traction, capturing the attention of SmackTok, known for dominating Gen Z sports culture online. Offsides was ultimately acquired for a multimillion-dollar sum, giving Popowitz his first major entrepreneurial milestone before even completing his undergraduate degree.
Now a student at Indiana University’s Kelley School of Business, Elijah balances academics with actively shaping the future of digital property management through his newest venture, Neptune. Neptune is positioning itself as the next wave of proptech, with a focus on streamlining the entire rental experience. From browsing listings to making payments and handling maintenance requests, Neptune’s goal is to eliminate friction and inefficiency in the rental process. As property ownership and rentals become more complex in urban markets, Neptune aims to make renting as seamless as ordering an Uber.
What makes Elijah’s approach so compelling is his ability to see patterns across industries and move early on emerging trends. Just as Offsides recognized the convergence of sports entertainment and digital interactivity, Neptune is poised to capitalize on the growing demand for tech-enabled real estate services. Early signals from investors and operators show strong interest, and the platform is already gaining traction among property owners and renters alike.
Popowitz represents a new kind of founder: young, ambitious, deeply connected to digital culture, yet disciplined enough to build companies that create real value. While many young entrepreneurs chase trends, Elijah is quietly building businesses that fundamentally change how people engage with everyday activities—whether it’s watching sports or finding a place to live.
As Neptune grows, it’s clear that Elijah Popowitz isn’t just another young founder with a quick exit under his belt. He’s building a career defined by vision, execution, and long-term impact.
