Infobip vs Plain: at a glance
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 Plain?
Sidekick got skills and MCP; now Plain is clearing the path to move your history in.
Plain's recent releases built Sidekick from an in-thread helper into an operator that uses workspace skills and connects to any MCP server, with workflows becoming the trigger layer for that agent work. The newest entry moves to the other end of the funnel: custom importers pull past conversations in from any tool, including in-house systems, with no built-in importer required.

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.
Plain
7.5SUPPORT
Sidekick got skills and MCP; now Plain is clearing the path to move your history in.
◆ Current state
Plain's recent releases built Sidekick from an in-thread helper into an operator that uses workspace skills and connects to any MCP server, with workflows becoming the trigger layer for that agent work. The newest entry moves to the other end of the funnel: custom importers pull past conversations in from any tool, including in-house systems, with no built-in importer required.
◆ Where it's heading
Capability, then autonomy, then extensibility, and now onboarding. Removing the importer dependency means adoption stops being capped by Plain's connector roadmap, the same way the agent's ceiling stopped being its integration roadmap. The pattern across both is Plain declining to sit as the bottleneck between a customer's existing systems and its own product.
◆ Prediction
Expect the importer work to be followed by tooling that puts migrated history to use - Sidekick reading imported conversations for context is the obvious next step given the skills and MCP groundwork already shipped.
