What Speedflow does

Speedflow Communications Ltd. is a privately held UK-registered telecom software and services company founded in 2004, with its primary operational headquarters in Plovdiv, Bulgaria and a regional presence in London. The company develops and operates MediaCore, a proprietary carrier-grade Class 4 softswitch platform delivered in two principal variants: MediaCore SBC for wholesale voice routing (with integrated billing, advanced reporting, and a Guardian revenue-assurance and fraud-protection subsystem) and MediaCore SMS, an award-winning stand-alone SMS hubbing and bulk-messaging platform supporting SMPP, SS7, and HTTP protocols. The MediaCore stack supports SIP and H.323 for VoIP, STIR/SHAKEN call authentication, and includes automation features such as CPS management with Random Early Detection and Tail Drop algorithms, real-time reporting under 60 seconds, and routing/billing automation claimed to improve operational efficiency by up to 60%. Additional product lines include NexaMSG (messaging platform), AccuCore, and AdCharge (advertising services), extending the company's footprint beyond wholesale voice and SMS termination services.

Speedflow monetizes through a mix of MediaCore software licensing and rentals (capacity tiers from 1,000 to 4,000 concurrent calls on monthly subscriptions bundled with 24/7 technical support), usage-based wholesale voice termination (CLI, Non-CLI, and TDM routes worldwide), and usage-based wholesale SMS termination (A2P, OTP, SMPP, and SS7 interconnections to hundreds of operators globally). Customer segments are primarily VoIP carriers and telecom operators (wholesale voice termination, call-center traffic), SMS aggregators and messaging businesses (A-Z termination, bulk messaging), and emerging VoIP entrants modernizing legacy infrastructure. The company sells exclusively through direct enterprise field sales supported by dedicated account managers and relationship-driven presence at telecom industry events such as GCCM Berlin 2026, with no resellers or distributors and pricing conducted on a quote basis.

The company is founder-led by Vlad Ellis (CEO) and Nata Ellis (COO) and operates with a headcount of 51-100 employees, serving more than 1,000 organizations globally. It has no disclosed external funding, parent company, or acquisition history. Speedflow's compliance posture includes GDPR alignment, and the company maintains an ongoing development cadence, most recently with the January 2023 release of MediaCore v4.9 incorporating STIR/SHAKEN support. Operational sustainability is evidenced by continued copyright coverage extending to 2026, active podcast and content production, and sustained partnership relationships exceeding a decade with named customers such as Talk2All Telecom Ltd and Family Communication Pte Ltd.
