Having shared ideas and good communication among co-founders is vital for pushing a startup forward.

It's important for founders to clearly communicate what they do in a way that anyone, including their grandparents, can understand, as this aids in word-of-mouth growth.

In co-founder conflicts, it's essential to communicate openly, as most relationship issues stem from communication breakdowns.

In the early stages, founders should not prioritize marketing and PR, but as the product gains traction, they need to take charge of messaging and communication to ensure consistency and clarity. Developing personal relationships with journalists is crucial; they prefer talking to founders rather than PR representatives.

Founders and core team members should develop the skills to talk to users instead of relying on others to be the go-between.

To avoid co-founder breakups, have regular one-on-one conversations to address disagreements and maintain open communication.

Founders should be the ones doing sales in the beginning to learn how to effectively communicate with customers and understand their problems.

Word of mouth growth is the cheapest way to grow your startup, and it's crucial to communicate your idea clearly so that anyone can talk about it easily.

It's crucial to have difficult conversations regularly to prevent stress and fractures in the co-founder relationship over time.
