Common Tongue

What Common Tongue does

Common Tongue is a privately held, bootstrapped software company headquartered in Prague, Czech Republic, that operates a collaborative online application for managing professional and personal projects. The platform is built around a single unified data model that interconnects todos, mind maps, calendar/scheduling, communication threads, Gantt/timeline views, timesheets, and budget tracking, allowing any entity to convert between message thread, appointment, and cost item without copy-paste duplication. The company launched publicly on December 21, 2012, and distributes the product globally via a web application (speak.commontongue.com) and native iOS and Android apps, with integrations to Google Calendar (two-way sync) and Google OAuth2 (social login).

The company serves a horizontal user base of individuals, creators, and small-to-medium groups, with no vertical specialization. Its go-to-market is purely product-led growth: free self-serve sign-up, social login, no sales team, and organic discovery through search, Facebook, Twitter, and word-of-mouth referrals originating from the founders' own use of the product. Revenue mechanics are presently a freemium model where all features available at launch remain permanently free, and paid premium modules are being defined as the future funding mechanism — explicitly chosen to avoid advertiser-driven monetization. The company emphasizes data ownership, daily backups, GDPR compliance, and on-demand data export as core principles.

Common Tongue operates with 1-10 employees, has no external institutional funding, no parent company, and no disclosed revenue. There is no published management team, no patents or trademarks registered, no named customers, and no disclosed AI/ML capabilities. Strategic activity since 2012 has been limited to mobile app launches, Google integrations, a 2024 GDPR privacy policy update, and the still-pending definition of premium paid modules.
