- AI Agents are the enablers who write most of the code and solve repeatable tasks to help the Engineers maximize their impact
- Everyone contributes to making Saily effective by suggesting new areas for improvement to delegate to agents and then implementing the changes

- Customer, having a comfortable, connected, hassle-free journey is never lost from the focus
