Comunications Skills

I have technical background and founder of software startup. Now, I started learning the importance of Communications Skills in demos and meeting with prospective clients.

Any books or courses recommendations to conquer this field as well?

Thanks

I second Toastmasters. Speak often.

And even moreso I'd post videos of yourself on Facebook and ask for hard and constructive criticism. Pick a semi-simple topic...how google works... and do a 5 minutes on that. Use a few props.

Self-improvement books are not communication books. Neither are persuasion books...they are great for tips about content but you really want to learn about being both relaxed and present - to be able to speak on or off-the-cuff to group or in-person.

I like Resonate by Duarte in that it speaks to preparation, but doing it with feedback is the direct route. I can speak to that (NO PUN!!!) from experience.

• How to Win Friends and Influence People is a great book for general, all-around people skills. Useful for business and your personal life.
• The 7 Habits of Highly Effective People is good for general self-improvement.
• For demos, I'd recommend Toastmasters

Rather than books and digital learning. As you are a founder of a company you will be surely financially fit. So, why not you appoint a personal lady secretary who is good at speaking English. And you can learn very easily and in best time. :-)
