Alex says that doing so will help the company reach more of its "potential market."

Potential (potential) here means possible, so the "potential market" is a group of people who do not buy the product right now, but would probably or possibly be interested in it.

You can also use potential as a noun, such as "He's got great potential," meaning he has great possibilities; he will do great things in the future.

Alex explains that after the presentation there will be a discussion to get people's "feedback" (feedback), or positive and negative reactions about what they just heard.

Then they will put their heads together to see if there are any other ideas.

The phrase "to put our heads together" means to work as a group to think of new ideas about something.

For example, Lucy and I always put our heads together to think of ideas for new and interesting ESL Podcasts.

Alex says that he wants "to say a few words" while the team is getting set up or getting ready to give the presentation.

This means that he wants to speak about something for a short period of time, maybe a few minutes.

Sometimes at a meeting, we ask someone to stand up and say a few words, meaning to talk to the whole group for a few minutes about some topic.
