Tfiber

What Tfiber does

TFiber is a privately held Romanian internet service provider operating under the legal entity S.C. SIL MIRO COM SRL, headquartered in Bucharest and serving Bucharest and surrounding areas. The company delivers residential and business internet connectivity primarily through Fiber-to-the-Home (FTTH) infrastructure supporting speeds up to 1000 Mbps external and metro, complemented by 3G/4G mobile internet, an in-development digital television offering, and data center services. Its core product portfolio comprises four residential fiber tiers (Fiber 40, 80, 150, and Power) priced 40-150 RON/month and three business fiber plans priced 90-200 EUR/month, with add-on services including free web hosting on mid-to-premium tiers and commission-free online bill payment via EuPlatesc, QIWI, and ZebraPay/SelfPay terminals.

The company operates a direct-to-consumer go-to-market model through its website tfiber.ro, offering online ordering, 12-36 hour installation windows, no installation fees within coverage areas, and short or no minimum contract terms (1-day minimum on residential plans). It holds ANCOM telecommunications regulator authorization and ANPC consumer protection compliance, and publishes quarterly service quality indicators under a 95% uptime guarantee with service credits for non-compliance. TFiber is closely held with 1-10 employees and no disclosed institutional investors, parent company, or external funding.

TFiber's business model is a straightforward monthly recurring subscription model, with revenue generated from residential internet subscriptions (40-150 RON), business internet subscriptions (90-200 EUR), and ancillary fees for mobile internet and add-on services. Customer segmentation is horizontal — split between individual households (primary) and SMB/enterprise clients (secondary) — with no disclosed named customers or large-anchor accounts. Geographic scope is limited to a single country (Romania) and a single metropolitan area, with no signals of expansion into adjacent regions or verticals beyond the planned IPTV and data center adjacencies.

Direct peers

• Euroweb Romania: Bucharest-based internet and connectivity provider serving business and residential customers with fiber and dedicated internet services. Closely comparable in scale, geographic focus, and B2B/B2C mix to TFiber.
• Nextgen Communications: Romanian fiber network operator providing wholesale and retail fiber services, including to ISPs and enterprise customers. Comparable as a fiber-focused operator in the same market, though with a more wholesale-oriented model.
• RCS & RDS (Digi): Romania's largest alternative telecom operator and dominant FTTH ISP with national fiber coverage, mobile, TV, and fixed-line bundles. Direct competitor in residential and business fiber within Bucharest, but at vastly greater scale.
• GTS Telecom (part of Deutsche Telekom): Romanian telecom operator providing fiber internet, data center, and managed connectivity services primarily to businesses. Overlaps with TFiber's business fiber and DataCenter offerings in Bucharest.

Broad incumbents

• Vodafone Romania: Major incumbent offering fiber broadband bundled with mobile and TV across Romania. Overlaps with TFiber's residential and SMB connectivity offerings, but with substantially larger footprint and brand.
• Telekom Romania: Fixed-line and mobile incumbent offering FTTH and fiber-based business connectivity across Romania. Competes in the same Bucharest metro and B2B segments as TFiber, with significantly broader infrastructure.
• A1 Romania: Telecom operator in Romania offering fixed broadband, mobile, and TV bundles. Overlaps in residential broadband and bundled connectivity, with greater scale and infrastructure breadth.
• Orange Romania: Incumbent mobile and fixed-line operator offering FTTH bundles with TV and mobile in Bucharest. Competes for the same residential and SME customers but as part of a much broader national portfolio.

Emerging players

• Starlink (SpaceX): Satellite-based broadband provider expanding across Romania. Competes for residential internet customers in areas where TFiber's fiber coverage is absent, but uses fundamentally different (wireless/satellite) delivery.
• Yallo (Swisscom subsidiary / Mobile Vikings): Smaller MVNO and connectivity brand in Romania offering mobile and home internet services. Competes on price-sensitive segments similar to TFiber's lower-tier offerings, though primarily mobile-focused.
