What Parallel Infrastructure does

Parallel Infrastructure, operating under the Harmoni Towers brand following its 2022 acquisition, is a privately held US telecommunications infrastructure company headquartered in Charlotte, North Carolina. It designs, builds, owns, and operates a nationwide portfolio of colocation-ready macro towers, build-to-suit towers, and specialized infrastructure serving wireless service providers, property owners, and military installations. The combined footprint spans more than 40 US states and includes over 2,000 macro towers, 200+ military base locations, 2,800+ industry partners, and 65,000 miles of railroad corridor right of way under partnerships with BNSF Railway and Union Pacific. Core technical assets are the long-dated railroad right-of-way agreements and colocation-ready tower positions, which enable fast-track deployment from site acquisition through construction and ongoing operations.

Revenue is generated through five streams: recurring tower colocation subscriptions (tenants pay for hosted space on existing towers), one-time build-to-suit tower development (custom construction from site acquisition through ongoing operations), ground lease buyout transactions (upfront cash payments to property owners to acquire or restructure ground leases), tower acquisitions (purchasing third-party-owned tower assets), and managed-services revenue from military base telecommunications infrastructure. Pricing is quote-based under multi-year B2B contracts rather than publicly disclosed, consistent with the custom nature of tower builds and lease terms. Go-to-market is an enterprise field-sales model with six regionally assigned account representatives (West, Central/North Plains, MOKAN/Texas, Midwest/UPNY, Southeast, East Coast) targeting property owners for ground leases, wireless service providers for colocation and build-to-suit, and vendors for development partnerships. The company is led by CEO Yannis Macheras with a leadership bench including CFO Jack Barry, COO Bill Davison, CDO Ron Bittner, SVP Site Development Mary Lou Boscardin, SVP Business Development Mike Meadows, and SVP General Counsel Kimberly Calcasola. Headcount is in the 51-100 range; the company is privately held with no disclosed funding rounds or institutional ownership details.
