What's the best strategy to set a brand tone of voice for a startup?

In my opinion, the best strategy to set a brand tone of voice for a startup is to first identify the target audience and understand their preferences and values. Then, develop a clear brand persona and messaging that aligns with the startup's values and mission. It's important to keep the tone consistent across all channels and touchpoints, and to use language and style that resonates with the audience while also standing out from competitors. Regularly revisiting and refining the tone of voice based on feedback and market changes can also help the startup stay relevant and effective in its communication.
