What SMSAPI does

SMSAPI, legally LINK Mobility Poland sp. z o. o., is a Polish Communications Platform as a Service (CPaaS) provider founded in 2007 in Gliwice, Poland, and operating as a subsidiary of LINK Mobility Group since the 2017 acquisition. The company operates a proprietary SMS gateway supporting SMS, MMS, Voice Message Service (VMS), RCS, and WhatsApp Business API over REST API and SMPP protocols, with throughput capacity of more than 6 million messages per hour, 99.9% deliverability, and reach into 220+ countries through the parent group's network spanning 30 countries and 700+ employees. Native client libraries cover PHP, Python, Java, C#, JavaScript (Node.js), and Go; the platform exposes OAuth2 token-based authentication, HLR number validation, two-factor authentication (SMS Authenticator), branded alphanumeric sender IDs, and a 2026-launched Model Context Protocol (MCP) server that allows AI agents to send and receive messages programmatically. SMSAPI is ISO 27001:2022 certified, GDPR/DORA/NIS2 compliant, and listed on the Polish UKE integrator registry for public-sector engagements.

Revenue is generated primarily through usage-based per-message pricing (Polish domestic SMS at PLN 0.08-0.16 per message; international at PLN 0.35) plus monthly subscription fees (PLN 49/month) with volume discounts, virtual-number rentals (PLN 99-299/month depending on contract length and number type), and enterprise contracts with 24-month terms for accounts exceeding 100,000 messages monthly. The platform monetizes through four go-to-market motions: API-first developer integration, enterprise field sales with dedicated account consultants, product-led growth via a free 50-message test account and self-service portal, and channel partners across the 200+ integration ecosystem. The customer base of 11,500+ businesses spans e-commerce, financial services, logistics, healthcare, government, NGOs, and technology platforms, with named enterprise users including ING Bank, IKEA Family, CCC, DHL Express, DB Schenker, TikTok, PayPal, JYSK, and MediaMarkt.

The redundant infrastructure spans ATMAN and T-Mobile data centers located 150+ km apart, with continuous 24/7 monitoring from a 10-person Network Operations Center (NOC) team. Distribution combines a self-service web portal (ssl.smsapi.pl), native iOS and Android applications, an enterprise sales function, integration marketplaces, and Zapier-mediated access to 5,000+ third-party applications. The company holds active social, developer, and content channels across LinkedIn, X, Facebook, Instagram, YouTube, and GitHub, supplemented by a Polish-language blog, regular webinars on ClickMeeting, and an inbound PR presence in Polish business media.
