# The best AI voice agents for business in 2026: build or buy

By Leo Jorge, Co-founder of Conrad. Updated November 2026.

You can build an AI voice agent on a developer platform or have one built for you. Platforms give you full control if you have engineers to build and maintain it. Conrad is our pick if you want agents that call and text, built around your process and running in weeks, without hiring a team to build them.

## Building is the easy part

A demo agent takes an afternoon. The hard part is everything after: real callers saying unexpected things, handoffs to your team, texting, follow-up schedules, opt-outs, quiet hours and keeping it working as your process changes.
