What IsoFusion does

IsoFusion Inc. is a privately held, vertically integrated internet infrastructure and IT services provider headquartered in Seattle, Washington, founded in 1991 as ISOMEDIA and operating continuously under founder leadership for 35 years. The company holds Competitive Local Exchange Carrier (CLEC) licenses in Washington and Indiana and a Certificate of Public Convenience and Necessity (CPCN) in California, supplying regulated telecommunications services through a portfolio of six wholly owned sub-brands: GigabitNow (fiber-to-the-home internet for residential and community networks), Colocation Northwest (data center colocation across the Pacific Northwest), Connect Northwest (residential and business fiber/Ethernet services), One Server Hosting (dedicated servers, VPS, and Plesk-based web hosting), TrueRing (business-grade VoIP/SIP), and Seanet (legacy residential internet and phone services).

Underlying infrastructure includes eight data center facilities totaling approximately 20,000 square feet, interconnected by a proprietary 180 Gbps dark fiber loop circling Lake Washington and providing access to more than 250 carriers and service providers; the network is monitored 24/7 from a primary Network Operating Center in downtown Tacoma. Subscribers span residential customers, small and mid-sized businesses, municipalities, HOAs, senior living communities, and enterprise tenants (including a global top-5 video game publisher occupying a high-density wing in Bellevue). Combined customer count is reported between approximately 13,000 and 23,000 residential and business subscribers, with GigabitNow open-access fiber networks passing more than 135,000 homes and businesses across seven states.

Revenue is largely subscription-based and recurring, drawn from residential FTTH subscriptions, business fiber and Ethernet circuits, colocation leases (cage, full/half/quarter rack), dedicated hosting and managed cloud services (including a VMware Cloud Provider Program 'MasterCloud' offering), VoIP/SIP service fees, and managed-services contracts for community fiber network design, construction, and operation. Go-to-market is hybrid: direct sales via phone/email and six branded websites for self-serve SMB and residential conversion; field sales for enterprise colocation and large fiber builds; channel partnerships with construction firms (most notably Cannon Companies) for fiber deployment; and government/grant-funded procurement vehicles, exemplified by the $17 million California Public Utilities Commission Last Mile Federal Funding Account award secured in 2025 for the west Sonoma County build. The company is led by co-founder Stephen Milton (CEO/CTO) and co-founder Dan Sivils (President/COO), with a board augmented by Microsoft Chief Technical Advisor Dave Crowley and Cannon Companies President Mike Cannon.
