“Can a tech-enabled brokerage platform become the full operating infrastructure layer for independent real estate agents and boutique teams at scale?”
Side was founded in 2017 (formerly Wayfinding/Reside Network) to operate as a behind-the-scenes brokerage platform, allowing high-performing real estate agents and teams to form their own boutique brands while Side handles compliance, legal, marketing, and technology infrastructure. The company scaled rapidly through 2021, reaching a $2.5B valuation and announcing IPO preparation, positioning itself as the operating system for independent real estate professionals rather than a traditional brokerage. Modern Treasury is listed as a customer-vendor relationship, suggesting Side uses Modern Treasury for payment operations and ledger infrastructure tied to real estate transaction flows.
