KEYNOTE: Aaron Witt

Founder, BuildWitt

Aaron Witt grew up in Scottsdale, Arizona, without a thought of who builds our world. That was until a construction project appeared in his neighborhood... Following high school, he started working on the same project as a laborer, and he was hooked.

After earning an engineering degree and a short career in construction, Aaron started telling Dirt World stories on social media for fun under the "BuildWitt" name. One follower became one hundred, and one hundred became millions...

Today, BuildWitt is a leading construction software company helping hundreds of Dirt World businesses train their workforce. Aaron's job is simple—grow their brand, which is now one of the most influential in the construction industry, as big as possible.

To do so, he travels to construction and mining operations worldwide to tell the stories of those who keep our world moving, generating nearly one billion views annually online!
