What IIG does
Intermountain Infrastructure Group (IIG) is an independent fiber infrastructure owner and operator headquartered in Burlingame, California, founded in 2018. The company builds, owns, and operates physical fiber networks across the Western United States and Canada, serving service providers, hyperscalers, cloud providers, enterprises, public sector organizations, and data center operators. IIG's core product portfolio includes Wavelengths (DWDM-based, 10Gbps to 800Gbps), DWDM Channels, Optical Fiber (dark fiber), and Ethernet Private Line Data Services at 1G, 10G, and 100G speeds. Supporting infrastructure services span Route Development, Construction Management, Fiber Optic Test and Turnup, Network Optimization, Route Maintenance, Emergency Response, and Optical Equipment Planning and Installation.
The company's primary technology is a multi-conduit fiber optic architecture using next-generation optical transport including DWDM systems, capable of supporting 400Gbps immediately with scalability to 800Gbps and beyond. Notable infrastructure assets include a fully redundant 150-mile Central Washington Ring featuring proprietary submarine fiber cable installation through the Columbia River, a California Bay Area Peninsula Network, and the Northern Tier Fiber Route — a 2,000+ mile long-haul corridor connecting the Pacific Northwest to central U.S. markets that was 70% complete as of June 2026 with full commercial availability targeted by end of 2026. A 24/7/365 Network Operations Center provides operational support, and the company reports 6+ years without a dig-related service outage in the San Francisco Bay Area.
IIG operates a B2B enterprise field sales model with direct customer engagement via inquiry forms, dedicated sales lines, and emergency response contacts. Pricing is Individual Case Basis (ICB) on multi-year contracts, with no publicly disclosed standard tiers. The company is privately held with Wafra as majority shareholder and Future Standard as a core institutional backer, with prior investment from Post Road in 2023. A proposed acquisition by Acceler8 Ventures PLC was announced in April 2026. The company employs 11-50 people across offices in Burlingame, Denver, Quincy, and East Wenatchee.

IIG competitors and assessment
Company assessmentDirect peers
- Zayo Group: One of the largest privately-held independent fiber infrastructure operators in North America, offering long-haul and metro dark fiber, wavelengths, and managed services to carriers, hyperscalers and enterprises. The closest direct competitor to IIG's long-haul, DWDM and dark fiber business across similar customer segments.
- FiberLight: Private fiber infrastructure operator providing dark fiber and lit services across regional and metro corridors in the US. Highly comparable to IIG as a mid-sized independent owner-operator serving similar carrier, hyperscaler and public-sector customers.
- Segra: Private fiber operator offering wavelengths, Ethernet, dark fiber and managed services across the Eastern and Central US. Operates a similar independent fiber model with comparable product set to IIG's wavelengths, dark fiber and infrastructure services.
- Lightpath (Altice USA): Fiber infrastructure business within Altice USA providing dark fiber, wavelengths and managed services to enterprise, carrier and hyperscaler customers in the Northeast and Mid-Atlantic. Closely comparable fiber product portfolio and go-to-market to IIG.
Broad incumbents
- Lumen Technologies: A major incumbent tier-1 US carrier with one of the largest fiber footprints in the country, selling wavelength, Ethernet, dark fiber and managed network services to enterprise and carrier customers. Competes with IIG across long-haul and mid-haul segments and is the dominant legacy-carrier alternative IIG positions against.
- Crown Castle Fiber / Crown Castle Inc. Owns and operates long-haul fiber plus a national tower/edge portfolio, and provides fiber and connectivity to carriers, hyperscalers and enterprises. A broader incumbent with overlapping lit and dark-fiber services in markets adjacent to IIG's footprint.
- ExteNet Systems (Crown Castle subsidiary): Owns and operates fiber and wireless infrastructure supporting carriers, enterprises and hyperscalers with a focus on distributed networks and connectivity solutions. Competes with IIG's enterprise-focused fiber offering in adjacent geographies.
- Consolidated Communications (now private, Searchlight Capital): Established fiber carrier operating a long-haul and metro network across more than 20 US states, offering wavelengths, dark fiber and enterprise services. Broader incumbent alternative to IIG with similar enterprise and carrier product suite.
Emerging players
- Extenet / euNetworks: Independent bandwidth infrastructure provider operating a fiber network across Western Europe and select US routes. Comparable in product positioning (long-haul wavelengths/dark fiber for carriers and hyperscalers) but with a primarily European footprint.
Regional players
- Vexus Fiber: Independent fiber operator building and operating fiber networks in Texas, New Mexico, Louisiana and other underserved regions. Comparable fiber construction and owner-operator model, but with a regional (non-overlapping) geographic footprint versus IIG's Northern Tier focus.
