What CallMultiplier does
CallMultiplier is a privately held, Oklahoma City-based provider of cloud-based automated voice broadcasting and mass SMS text messaging services, founded in 1995 and operating continuously as an independent company. The platform enables organizations to record or upload voice messages and send them to groups ranging from 25 to 1,500+ contacts, alongside complementary SMS text blast, phone tree, auto dialer, robocall, group texting, and emergency notification products. Core technical components include advanced voicemail detection (audio signal processing for answering machine tones), custom caller ID, message playback numbers, polling/member response capture, subgroup management (up to 99), multi-group account structures, automated retries (up to 10), and a developer API for integration with external software.
The company monetizes through two parallel pricing models: monthly or annual unlimited-usage subscriptions tiered by maximum member count ($7.99 to $253.99/month, with 5-10% term discounts), and pay-per-message credit packages ranging from 250 to 100,000 credits at decreasing per-unit cost. Distribution is exclusively direct-to-consumer via self-serve website signup and a 24/7 toll-free phone support/sales line, supplemented by referral and affiliate programs; no third-party resellers or app stores are used. The customer base spans nine named verticals with primary focus on religious groups, schools and universities, businesses, sports teams and leagues, staffing companies, and non-profits, and secondary focus on clubs and associations, property management, and government entities, serving 10,000+ organizations across the US and Canada.
