Courtney Allen, 33, had a hunch PowerPoint presentations could be a full-time job.

Allen grew up in Atlanta, Georgia, and got her degree in graphic design from Boise State University in 2012. Passionate about presentation design and having used the software in the past, when it came time to present her senior portfolio, "it was all PowerPoint," she says. "And people thought that was a bit weird. 'What sort of job are you going to get just doing PowerPoints for a living?'" they asked. But she was determined to figure it out.
