Meet the team

Landon Rhodes

Landon Rhodes

Founder & CEO

Landon started Grindstone on the floor of his apartment in 2018. He wanted to find a way to help companies promote their products and services beyond the traditional door-to-door sales model. He also wanted to take the work ethic he developed on his family farm near Exeter, Nebraska and grow his own successful business.

To keep himself sharp, Landon listens to podcasts and reads books focused on entrepreneurship and personal development. He even hosts his own podcast called Spark to Fire where he interviews other successful business leaders. He’s a firm believer in the mantra: “If you’re not growing, you’re dying,” and applies that mentality to everything he does.

Fun fact: Landon’s impressions are impeccable. Ask him to do anyone and he won’t disappoint.
