iPaaS, integration platform as a service, is the category of middle-layer products that wire systems together: Zapier, Make, Workato, Mulesoft, Boomi. They are excellent for low-volume, asynchronous sync between SaaS tools. They are not excellent for the real-time, transactional integration an AI agent needs.
The latency math is the issue. An iPaaS round-trip (agent to iPaaS to CRM and back again) adds 500-1500 ms to every tool call. On an LLM-dominated turn latency budget, that is a meaningful tax. On a stack of tool calls, it compounds.
The right architectural choice for an AI agent is native CRM integration on the critical path (booking, lookup, write) and iPaaS on the periphery (downstream notifications, BI sync, analytics). A vendor that routes everything through iPaaS is making the latency choice for you.
Vorel uses native CRM APIs on the agent's critical path. iPaaS layers are supported for downstream sync (BI, analytics, marketing automation) where the latency does not affect the caller.
