Upfront, yes. But the ROI is fundamentally different. ChatGPT saves minutes per task. A custom agent can eliminate entire processes, saving hours per day.
Your data stays within your infrastructure. We can deploy agents on your own servers or use European-hosted cloud providers for GDPR compliance.
