What is the importance of knowing how to start a presentation?
Knowing how to start a presentation is an essential part of giving an effective speech or discussion. By coming up with an engaging start to your presentation, you can capture your audience's interest and help them focus on what you are going to share. Your introduction can help audience members understand the purpose of your presentation. When presenting in front of an unfamiliar audience, it also is your opportunity to introduce yourself as a speaker, helping you make a connection with your audience.
Good presentation introduction examples
Here are several examples of quality presentation introductions you can use as inspiration for your own:
Example 1: Business conference presentation
Here is how you might begin a presentation for a business conference:
"Hello, everyone. My name is Aja Patel, a seasoned business leader in the world of beauty products. Over the course of my career, I have helped five start-up beauty brands become top-tier brands in the Indian market. I have served as the creative director for three award-winning campaigns and helped several brands completely change their image.
Now, why am I telling you all this? Because I want to help your brand break into this saturated industry. Over the course of the next 30 minutes, I am going to share more about my personal story in this industry and share insider advice on how to leverage your brand for success."
Example 2: Client project presentation
Here is how you might begin a client meeting:
" Hello, team. As most of you already know, my name is Diya Reddy. I am the senior graphic designer at Art Works. Today, I am going to go over our team's work for the Nelson campaign. By the end of this meeting, I am hoping to give you a better understanding of the new branding direction. I plan to cover colour pallets, logo design, website layouts and brochure mockups. Does anyone have any questions before we get started?"
