What US Fiber does
US Fiber, operating as U.S. Internet and USI Fiber Internet, is a regional fiber internet service provider headquartered in Minnetonka, Minnesota, serving the Twin Cities (Minneapolis/St. Paul) metropolitan area. The company builds and operates fiber optic infrastructure delivering residential and business fiber internet, business phone service, email hosting, cloud hosting, colocation and data storage, and carrier/enterprise access solutions. Its underlying technology is standard fiber optic internet infrastructure with dedicated last-mile connectivity to customer premises, supplemented by an in-region data center footprint that supports colocation and cloud hosting services.
The company's revenue model is built on recurring subscription fees across five streams: residential fiber internet, business fiber internet, business phone, cloud hosting and colocation, and carrier/enterprise access. Business pricing is quote-based while residential pricing and sign-up have been redirected to T-Mobile's national platform following the acquisition. Go-to-market is hybrid: a sales-led direct motion for business customers emphasizing local, phone-based support, plus a direct-to-consumer self-serve motion for residential customers via T-Mobile's website. As of 2026, USI is now part of T Fiber, a T-Mobile service, with the USI brand retained for business services in the Twin Cities while residential distribution has shifted to T-Mobile's platform. The company employs approximately 11 people.

US Fiber competitors and assessment
Company assessmentEmerging players
- Google Fiber: Fiber ISP selling gigabit residential and business connectivity in selected metros; comparable in FTTH product and target customer, though operating at a different stage of geographic expansion and capital profile.
Direct peers
- TDS Telecom: Regional fiber and wireline ISP serving Midwestern communities with residential and business connectivity; comparable to USI in scale, regional focus, and product mix including voice and managed business services.
- Ziply Fiber: Regional fiber ISP operating across the Pacific Northwest and parts of the Midwest with residential and business fiber; comparable in scale, technology stack, and go-to-market as a smaller regional FTTH provider.
- Metronet: Regional fiber-to-the-home ISP also serving the Twin Cities — USI's own website routes residential construction inquiries to Metronet — and also acquired by T-Mobile, making it the closest direct comparable in footprint, technology, and now ownership.
- Verizon Fios: Pure-play fiber-to-the-home and business fiber ISP comparable to USI in technology and product mix (internet, voice, business services); a relevant analog for the FTTH operating model even though its geographic focus differs.
- Frontier Communications: Fiber-to-the-home and business fiber ISP with a regional operating model similar to USI; sells residential and SMB connectivity in Midwestern markets and competes for the same fiber-building economics and customer segments.
- Consolidated Communications: Regional fiber and broadband provider across the Midwest with residential, business, and wholesale offerings; highly comparable to USI's horizontal fiber-plus-voice-and-data-center product set in adjacent geographies.
Broad incumbents
- Comcast (Xfinity): Dominant cable broadband and bundled services provider in the Twin Cities metro; competes directly with USI's residential fiber and business services as a large incumbent with national brand and capital.
- Lumen Technologies (CenturyLink): Incumbent wireline carrier with fiber and DSL services across the Twin Cities; overlaps with USI's residential and business fiber offerings while operating at national scale as a much broader telecom provider.
- AT&T Fiber: National fiber broadband provider selling into the Twin Cities; competes with USI for residential and SMB fiber subscribers with the backing of a national carrier's brand, bundles, and capital.
