Cooolbox

What Cooolbox does

Cooolbox AD (legal name: Кулбокс АД) is a private Bulgarian high-tech telecommunications company headquartered in Plovdiv, operating since approximately 2000 (as successor to ITD Network, which was founded around 1997 and rebranded to Cooolbox around 2022). The company delivers residential and business connectivity services across three Bulgarian cities — Sofia, Plovdiv, and Veliko Tarnovo — over a 100% company-owned Fiber To The Home (FTTH) network built on Active Optical Network (AON) technology, in which each subscriber is provisioned over a dedicated, non-shared optical fiber from the technical center to the premises. Its product portfolio comprises cooolNet (gigabit residential internet, EUR ~14.27/month), cooolOffice (1 Gbps symmetric business internet with static IP and SIP telephony add-ons, EUR ~40.39/month), cooolTV/coool.tv (interactive television with 130+ channels plus a Smart TV app for Android TV and Apple TV), cooolTel (IP telephony with included minutes), and the My Cooolbox self-service portal. Cooolbox runs proprietary in-house-developed networking equipment (i6850 FTTH gateway, MAG STBs, custom SFP modules) and offers no-term contracts with no installation fees across home services.

The company monetizes almost entirely through recurring monthly subscriptions, with ancillary revenue from premium TV packages (DiemaXtra, MAX Sport Plus), static IP address networks (/29 to /24 blocks), and personal 0700 number provisioning. The go-to-market is direct-to-consumer (DTC) via the cooolbox.bg website, coverage-check funnel, toll-free 0800 45 845 phone sales line, My Cooolbox portal, and an 'Invite Friends' referral program offering an EUR 8.00 bilateral discount. Customer segments are residential households (primary), small-to-medium businesses needing static IPs and SIP trunks (secondary), and other operators requiring interconnection (tertiary). Payments are accepted through EasyPay cash offices, ePay.bg, and Trans.card online billing. The company employs 101–250 staff, holds no disclosed external institutional funding, and discloses no revenue, ARR, or subscriber count.

Beyond connectivity, Cooolbox advertises a 24/7 technical support operation with on-site visits within 24 hours, in-house network diagnostics enabled by the dedicated AON architecture, and marketing technology integrations (Google Analytics 4, Meta Pixel, Meta Conversion API, LinkedIn Insight Tag, X Pixel, Hotjar) for analytics and remarketing. The company is privately held, with no subsidiaries, no disclosed M&A, no executive leadership publicly listed, no patents or awards disclosed, and no AI/ML products or features described in its materials.

Direct peers

• NetSurf (Bulgaria): Bulgarian independent ISP focused on FTTH/FTTP residential and business connectivity with proprietary fiber builds in selected cities. Most directly comparable to Cooolbox as a similarly sized Bulgarian FTTH-only challenger operating its own active fiber network outside the big-three incumbents.
• Bulsatcom: Bulgarian operator providing pay-TV and broadband services via cable and fiber. Comparable to Cooolbox on the residential triple-play (TV + internet) in regional Bulgarian markets, though historically cable-led rather than 100% fiber.
• Spectrum Net (Bulgaria): Bulgarian fiber and cable broadband ISP serving residential and SMB customers across multiple cities. Comparable as a like-sized alternative-fiber ISP competing in overlapping geography with Cooolbox on gigabit home internet and IPTV bundles.

Emerging players

• Deutsche Glasfaser: Independent German FTTH challenger building dedicated fiber networks in underserved/regional German markets. Comparable to Cooolbox in business-model terms — private-equity-backed independent FTTH operator monetising triple-play over its own AON/PTP-style fiber plant — though at much larger scale.
• CityFibre (UK): UK wholesale and retail FTTH operator building full-fiber infrastructure in secondary cities. Comparable to Cooolbox as a non-incumbent FTTH-only player competing against national incumbents (BT/VMO2) on dedicated fiber — useful peer for understanding the economics of FTTH challengers.

Regional players

• Telekom Srbija: Incumbent Serbian fixed and mobile operator with extensive FTTH rollout and bundled IPTV/VoIP. Comparable as a regional Balkan fiber/IPTLC operator with a similar triple-play model, but operating in Serbia rather than Bulgaria — useful peer for product and capex benchmarking.
• Makedonski Telekom: Incumbent North Macedonian fixed/mobile operator with fiber broadband, IPTV and VoIP. Comparable as a neighboring Balkan triple-play fiber operator with a converged product set similar to Cooolbox's, useful for regional benchmarking of pricing and ARPU.

Broad incumbents

• Vivacom (Bulgaria): Largest Bulgarian telecom operator offering nationwide fixed broadband (including FTTH), mobile, TV and enterprise services. Directly comparable because it competes head-to-head with Cooolbox in Sofia, Plovdiv and Veliko Tarnovo on residential fiber and business connectivity, but operates at vastly greater scale across mobile and B2B.
• A1 Bulgaria: Second-largest Bulgarian fixed and mobile operator with a growing FTTH footprint and converged quad-play bundles. Comparable to Cooolbox on the residential gigabit fiber and IPTV/VoIP bundle, but backed by A1 Telekom Austria Group's pan-European scale and capital base.
• Yettel Bulgaria (formerly Telenor Bulgaria): Bulgarian mobile-led operator that has expanded into fixed broadband (including fiber) and TV. Comparable as a competing broadband ISP in Cooolbox's three cities, with the added dimension of mobile convergence bundles that Cooolbox cannot match.
