What Nine does
Nine (legal entity: NextIntelligence.ai) is a Seoul, South Korea-based software developer founded in 2013 that builds mobile email and calendar applications for Android and iOS. Its core product, Nine - Email & Calendar, uses Direct Push technology over Microsoft's Exchange ActiveSync protocol to synchronize email, calendar, contacts, tasks, and notes in real time between user devices and Exchange/IMAP servers. All user data is stored locally on the device rather than on NextIntelligence infrastructure, with SSL and AES-256 encryption and OAuth2 used for Gmail authentication — a privacy-first architecture that the company positions as a differentiator versus cloud-mediated alternatives.
The company's enterprise product line, Nine Work (and its MDM-specific variants for AirWatch, MobileIron, Microsoft Intune, Rubus, and IBM Maas360), extends the core application into Android Enterprise deployments with app configuration policies for corporate-managed mobile environments. Nine monetizes through one-time perpetual software licenses priced at $11.99–$14.99 per device with tiered volume discounts for 5-, 10-, and 50-seat bundles, plus separately negotiated enterprise licensing for Nine Work. Go-to-market is primarily product-led via the Google Play Store, with direct enterprise sales handled through [email protected]. As of 2019 the company reported 200+ global enterprise customers, and the firm remains privately held with no disclosed venture or private-equity backing, operating with a headcount in the 11–50 range.
