Capital City Times
At just 20 years old, Elijah Popowitz has already exited one startup—and he’s not slowing down. After co-founding and selling the interactive sports platform Offsides to the rapidly growing media company SmackTok, Popowitz is now entering a new arena: real estate tech. His latest venture, Neptune, is designed to modernize a process that millions find outdated and frustrating—renting.
From missed emails to clunky portals and endless paperwork, the rental experience is one of the few areas of daily life still lagging behind digitally. Neptune aims to change that by offering a fully integrated, user-friendly platform for both renters and property managers. The concept is simple: build an all-in-one ecosystem that brings clarity, speed, and control to every stage of the rental lifecycle. From searching listings and signing leases to submitting maintenance requests or paying rent, Neptune streamlines it all in one place.
Think Stripe meets Slack meets Zillow—but purpose-built for rentals. Popowitz, now studying business at Indiana University’s Kelley School, saw the opportunity through his own interactions with outdated property systems. Where others see hassle, he sees infrastructure waiting to be rebuilt. Just as he forecasted the shift in sports media with Offsides, he believes the rental economy is ripe for reinvention.
Why Property Managers and Renters Are Taking Notice: For Owners & Managers: Neptune reduces operational friction, accelerates unit turnover, and improves tenant experience—all while cutting admin costs. For Renters: Everything is mobile, fast, and centralized. No more hunting for lease documents or waiting on hold for minor repairs. Why Investors Are Watching: Market Size: The U.S. rental industry exceeds $500 billion in annual value.
Category Opportunity: While sectors like finance and healthcare have been redefined by tech, rental processes remain largely untouched. Execution Track Record: Popowitz isn’t new to startups—he’s proven he can scale, exit, and move fast. With early adoption among landlords already in motion, Neptune is shaping up to become the digital operating system for renting property.
