What TeleHouse does
TeleHouse AD (Телехаус АД) is a Bulgarian data-transmission carrier founded in 2007 and headquartered in Sofia, operating as an independent public limited company that is not publicly traded. The company provides wholesale and enterprise connectivity services to telecom operators and corporate clients across Bulgaria, with a secondary footprint in Romania via two Points of Presence in Bucharest (NXdata-1 and NXdata-2, established November 2012). Its service portfolio spans IP transit and BG-peering, Carrier Ethernet (EPL/EVPL/EVPN), DWDM Lambda at 1/10/100 Gbps, SDH leased lines up to STM-256, Dark Fiber rental and IRU, and Radio Relay transmission, supported by a smaller consultancy practice covering M&A advisory, backbone design, IPTV/SIP implementation, and business-systems automation.
The technical backbone is a nationwide DWDM network with Nx100G lambda capability, dual-ring protection, ROADM devices and 99.999% yearly availability, complemented by 110+ Points of Presence across 30+ Bulgarian cities and a Tier-1 upstream ecosystem (TeliaSonera, Level(3)/CenturyLink, NTT) plus peering at DE-CIX and B-IX. The company's main technical center sits in the TelePoint colocation center, which it established in 2008 with financing from P&S EAST Growth Luxembourg and which carries ISO 9001:2015 and ISO 27001:2022 certifications — the latter reportedly unique in Bulgaria. TeleHouse holds a CRC electronic communications license, is registered as a Personal Data Administrator with CPPI, and operates a 24x7 NOC.
TeleHouse generates revenue primarily through recurring, multi-year subscription contracts with telecom operators and corporate clients, supplemented by Dark Fiber IRU prepayments and project-based consultancy fees. Pricing is quote-based and not publicly disclosed. Customer concentration is anchored by a flagship relationship with the BTT (Bulgarian Telecom and Television) group — for whom TeleHouse is the preferred data services integrator since May 2012 — alongside a reference list that includes Central Depository (financial sector), Interamerican Bulgaria / ACHMEA (insurance), RCS&RDS, Caucasus Online, GTS Telecom, and others. The firm employs 11–50 people and pursues direct enterprise field sales rather than channel or self-serve distribution.

TeleHouse competitors and assessment
Company assessmentOthers
- DE-CIX: World's largest Internet exchange operator and a strategic partner of TeleHouse. Comparable as an ecosystem/peer-exchange player whose peering model TeleHouse replicates at the Bulgarian level via its 55+ peering partners.
Direct peers
- RETN: Pan-European wholesale carrier specializing in DWDM wavelength, Carrier Ethernet, and IP transit with strong presence in CEE/SEE. Highly comparable operating model to TeleHouse: wholesale-only, infrastructure-led, multi-country footprint across the same region.
- B-IX (Bulgarian Internet Exchange): Bulgaria's neutral Internet exchange, listed as a TeleHouse customer. Comparable as the central Bulgarian peering fabric where TeleHouse both participates commercially and competes for member connectivity.
Broad incumbents
- GTT Communications: Global wholesale carrier providing IP transit, Ethernet, and wavelength services to enterprise and carrier customers. Comparable operating model and product set to TeleHouse, but with global scale and broader multi-country enterprise reach.
- Equinix: Global interconnection and colocation operator. Comparable as the platform partner of choice (NXdata is an Equinix-adjacent operator) and benchmark for high-availability, certification-rich interconnection services TeleHouse aspires to in Bulgaria.
- Cogent Communications: Global Tier-1 IP and wavelength wholesaler known for aggressive pricing on Internet transit and Ethernet. A key pricing benchmark for TeleHouse's IP services and Carrier Ethernet offerings.
- Vivacom: Largest Bulgarian incumbent telecom offering fixed, mobile, IPTV, and wholesale carrier services across the same customer base TeleHouse targets. Comparable as the dominant Bulgarian carrier against which TeleHouse competes for enterprise and wholesale IP/Ethernet deals.
- A1 Bulgaria: MNO/fixed-line operator part of A1 Telekom Austria Group with full B2B data, IP, and cloud-connect portfolios in Bulgaria. Directly competes for the same corporate connectivity customers TeleHouse serves, with deeper international reach.
- United Group: Largest multi-play operator in SEE (Serbia, Bulgaria via Vivacom-adjacent footprint, Bosnia, Croatia, etc.) operating backbone, IP, and enterprise services. A relevant comparable for scale, product breadth, and SEE cross-border ambitions that TeleHouse is starting to pursue.
- Lumen Technologies: Global wholesale carrier (formerly CenturyLink/Level 3) and one of TeleHouse's Tier-1 upstream providers. Comparable as the reference DWDM wavelength and IP transit wholesaler whose pricing and reach set the competitive floor in the region.
