Superhuman vs Threema
Side-by-side trajectory, velocity, and editorial themes.
Inbox becomes an MCP endpoint — agents now drive Superhuman alongside humans, in your voice.
Superhuman ships at very high cadence, mixing mobile polish (Quick Reply from notifications, calendar widget, Split Inbox reorder/hide) with category-shifting AI work. The April MCP launch turned Superhuman Mail into a callable surface for Claude, ChatGPT, and other assistants, with 'uniquely Superhuman' actions (Smart Send, Read Statuses, Split Inbox triage) exposed as tools. Draft Sync with Gmail/Outlook bridges the agent ecosystem further: assistants can draft anywhere, you review and send in Superhuman.
The product is moving from 'fast email for power users' to 'AI-and-humans share the inbox.' Personalization, Write with Voice, and MCP form a clear stack — voice in, agent action, voice out — with the original power-user keyboard-shortcut audience preserved through continued Split Inbox refinement. Mobile gets weekly polish to keep that surface from rotting while the AI direction takes the headlines.
Next likely move is delegated-inbox MCP actions for executive assistants (act-as-on-behalf permissions) and recurring agent tasks tied to Personalization rules. A cross-app demo — Superhuman + Granola + a calendar tool, all via MCP — is the obvious narrative the May 21st virtual event has been set up to deliver.
Threema leans on enterprise OnPrem features while sharpening its anti-WhatsApp, anti-Signal positioning.
Threema's recent activity splits between shipping and positioning. Concrete product work: a new in-app Survey Feed in the Threema Channel, the Liquid Glass iOS 7.1 redesign, DualLock for OnPrem chats on a lost or stolen device, and screenshot prevention in Threema Work for iOS. Most of the remainder is editorial — #DeleteWhatsAppDay, Zero Trust explainers, commentary on the politician-targeting Signal/WhatsApp attacks — aimed at sharpening the privacy positioning.
The growth story is increasingly the OnPrem and Work tiers. DualLock and anti-screenshot are explicitly enterprise security controls that put distance between Threema and consumer Signal. The publishing cadence around competitor incidents and privacy theory suggests Threema is courting decision-makers spooked by the recent Signal/WhatsApp narrative more than chasing consumer growth.
Expect more enterprise-shaped controls on OnPrem — finer admin policy, audit trails, additional device-loss safeguards — paired with continued public-positioning posts timed to competitor incidents. Consumer-side product investment looks deprioritised relative to the Work tier.
