Telnyx
Telnyx is building Voice AI into a full agent platform — shipping capability daily.
A side-by-side editorial comparison of Salesmsg and Threema — release velocity, themes, recent moves, and the top alternatives to consider.
Salesmsg makes the AI agent, not the inbox, the center of its product
Salesmsg is an SMS and calling platform for sales teams that has gone all-in on AI agents: calling agents, booking agents, and MCP access, layered on deep HubSpot and Salesforce integrations. The new Unified Agent consolidates agent-building into a single chat-driven interface where teams describe an agent in plain language, configure everything in one tab, and test in a live phone preview before launch.
Threema keeps privacy front and center while shipping small, workplace-focused features.
Threema's feed mixes privacy advocacy (anonymity, WhatsApp criticism, emoji culture) with a steady trickle of concrete product work. Recent shipping is targeted rather than sweeping: an availability/out-of-office status in Threema Work, a new in-app survey feed to gather feature input, and a running 'what we're working on' roadmap note.

The new Unified Agent consolidates agent-building into a single chat-driven interface where teams describe an agent in plain language, configure everything in one tab, and test in a live phone preview before launch.
The product is repositioning from a shared team-texting inbox to an AI-agent execution layer for outbound. Texting, calling, and meeting-booking are increasingly agent-run, with the CRM as the system of record and Salesmsg as the SMS and voice action layer. Recent months added MCP tools, autonomous booking into HubSpot, Salesforce Flow triggers, and per-automation credit tracking, all pointing the same direction.
Expect the Unified Agent to absorb the separate calling, booking, and texting agents into one buildable surface, and tighter credit and usage governance as agent volume and its cost climb.

Recent shipping is targeted rather than sweeping: an availability/out-of-office status in Threema Work, a new in-app survey feed to gather feature input, and a running 'what we're working on' roadmap note.
The product arc favors the business tier (Threema Work) and closer user feedback loops, layered on the unchanged core promise of system-level anonymity and local data protection. Expect incremental workplace-collaboration features and UI modernization (recent iOS 'Liquid Glass' refresh) rather than architectural shifts.
The survey feed suggests the next features will be user-voted collaboration and status refinements in Threema Work; the privacy-advocacy cadence on the blog will continue in parallel.
