What RoboKiller does
RoboKiller is a consumer mobile application that blocks spam calls and spam texts, marketed with a 99% effectiveness claim and operated as a subsidiary of Bending Spoons Operations S.p.A., an Italian holding company. The product is distributed on the Apple App Store and Google Play, with direct signup available in the U.S., Canada, Malaysia, and Singapore, and a separate Enterprise tier addressing business customers. The company reports 12 million U.S. installs and 463k app-store ratings averaging 4.5 stars.
The product is built on AI and machine learning capabilities including predictive analytics for real-time call classification, live audio fingerprinting that identifies scammers by voice pattern rather than phone number, NLP for SMS content and voicemail transcription, anomaly detection on call and text patterns, and autonomous conversational agents (Answer Bots) that engage scammers in voice dialogue to waste their time. These capabilities are backed by a proprietary database of 1.5 billion phone numbers. The product portfolio also includes RoboRadio, a content library of recorded Answer Bot conversations, a free reverse phone lookup tool (Spam Lookup), a free app tier (Robokiller Free), and an Enterprise offering.
The business model is a self-serve, product-led consumer subscription priced at $4.99 per month or $39.99 per year, with a 7-day free trial. Distribution is primarily through mobile app stores supplemented by content marketing (research reports on robocall and robotext trends), competitive comparison pages, and earned media coverage in tier-1 outlets. Awards include Apple App of the Day (2019, 2020), Webby Awards for Technical Achievement (2019, 2021), an FTC Robocalls Against Humanity competition win (2015), and a Stevie Award for Machine Learning & Bot (2021).
