What is Infobip?

A CPaaS rebuilding around AI agents that act, not just channels that deliver

Infobip publishes quarterly roll-ups, and the feed stores each quarter twice — once as a bare label, once as the summary paragraph. Across Q3 2025 to Q1 2026 the through-line is consistent: AgentOS unifying the communication stack, AI agents that take action rather than reply, MCP servers connecting models to real channels, and AI voice work under Vocalize, against continued WhatsApp, RCS and CDP investment.

What is Respond.io?

respond.io is layering an agent-authoring copilot and consumption billing on top of its omnichannel inbox.

respond.io ships something visible every few days across three fronts: channel coverage, the agent-facing inbox, and AI. Microsoft 365 and Outlook joined as a full email channel with workflow routing and reports, Calendly arrived as an integration, and Instagram Story mentions can now open conversations automatically. The inbox itself picked up a Cmd+K command palette, drag-out full-size image saving, and browser-tab unread signalling, while the mobile app gained offline message queuing.

A CPaaS rebuilding around AI agents that act, not just channels that deliver

◆ Current state

Infobip publishes quarterly roll-ups, and the feed stores each quarter twice — once as a bare label, once as the summary paragraph. Across Q3 2025 to Q1 2026 the through-line is consistent: AgentOS unifying the communication stack, AI agents that take action rather than reply, MCP servers connecting models to real channels, and AI voice work under Vocalize, against continued WhatsApp, RCS and CDP investment.

◆ Where it's heading

The company is repositioning from delivering messages to running autonomous customer interactions on top of them. Channels are becoming the substrate; the product being sold is the agent layer above. MCP servers matter most here — they make Infobip's channel reach callable by models a customer already runs, rather than requiring Infobip's own agent builder.

◆ Prediction

Expect the next quarterly to lead with AgentOS depth — orchestration, handoff and measurement across agents — since the channel and MCP groundwork it needs has now shipped over three consecutive quarters.

respond.io is layering an agent-authoring copilot and consumption billing on top of its omnichannel inbox.

◆ Current state

respond.io ships something visible every few days across three fronts: channel coverage, the agent-facing inbox, and AI. Microsoft 365 and Outlook joined as a full email channel with workflow routing and reports, Calendly arrived as an integration, and Instagram Story mentions can now open conversations automatically. The inbox itself picked up a Cmd+K command palette, drag-out full-size image saving, and browser-tab unread signalling, while the mobile app gained offline message queuing.

◆ Where it's heading

Two moves stand out from the steady feature drip. Copilot went into every workspace as an agent builder that drafts an AI Agent from a description and runs test cases against it before publishing — respond.io is attacking the authoring problem, not the runtime one. Alongside it, AI Credit On-Demand converts the AI allowance from a hard cap into metered overage, so automation stops breaking mid-conversation and AI becomes consumption revenue. The remaining work is a methodical widening of channels and the surfaces an agent touches all day.

◆ Prediction

Expect more channels to arrive in the same shape Outlook did — inbox, workflows, and reports together — and Copilot's authoring surface to extend past agents into workflows. The AI Agent wait-time and Copilot test-case work both point toward more pre-publish validation tooling.
