# How Long Does It Take to Build a Custom AI Agent?

Short answer

A well-scoped agent for one task usually takes 2 to 6 weeks.

In detail

A well-scoped AI agent handling one specific task — like lead qualification or support triage — typically takes 2 to 6 weeks from kickoff to launch. Projects that integrate across multiple systems, require custom data pipelines, or automate several workflows at once can take 2 to 3 months. The timeline usually depends more on how ready your data and integrations are than on the AI itself — messy source data is the most common thing that stretches a project.
