It's not easy being the youngest person in a room, and that's certainly the case for startup founders looking to make an impact on an industry that's been doing things a certain way since before they were born.

The five finalists of the Top Founder Under 40 category for the InnovationMap Awards presented by Techwave were asked to share their challenges overcame as young founders. Here's what they had to say. Click here to register for the livestream.

"It wasn't until I stood my ground by being persistent, and by not being afraid to hand their responsibilities to someone else, that they finally took me seriously."

"While working as on a Department of Defense Contract, I was leading a development effort with other older white men who were mostly retired military," she explains."They did not appreciate a young ethnic female giving them orders, and would often ignore my email requests or assigned tasks. At first, I felt defeated, but then I had to remember that although they have a lot of knowledge in general, I was the one with the right knowledge for this specific project."

"Changing the minds of experienced executives, who have worked in the energy industry for decades, was an uphill battle that took time and a considerable amount of effort."

"I think my go getter attitude has always helped me out and aid me mature faster."

"Once I started just being myself and not carrying the weight of the no's it really improved my productivity, my leadership, and my overall success as a person and as a leader in my business."

"I think advocating for myself and my business as a younger female founder has been a challenge mostly because as a person you want to please the people around you, investors, whoever, and sometimes no matter what you do, they aren't going to be on the same page and that's OK," she says. "But not carrying that forward is what's important. There's been times I've been told no, when I was trying to be exactly what I thought an investor or business partner wanted to hear."

"Typically, companies that have been around and have older leadership can have an advantage."
