For most SaaS and B2B teams, the honest answer to build vs buy AI agents is: buy the platform, build the differentiation. A custom GPT wrapper can prove the concept in a weekend, but production outbound — real-time voice, deliverability, compliance, follow-up state, CRM sync and permanent maintenance — is where the overwhelming majority of the engineering actually lives. Building is the right call
What this covers
- The weekend prototype is real — and that's exactly the trap
- What production outbound needs that a GPT wrapper doesn't have
- Real-time voice and the latency budget
- Deliverability and number reputation
- Compliance tooling: consent, DNC, audit trails
This is a technical summary. The full guide — with the tables and worked examples — is on our site: *Build vs Buy: Custom GPT Wrapper or an AI Agent Platform?*.
