Sock market

Jeremy Dunn, co-founder of the Athletic Community, discusses the company’s relationship with USPS in a new video.

The founders of an athletic clothing company in Portland, OR, say USPS has been critical to their success.

Julie Krasniak and Jeremy Dunn started The Athletic three years ago to sell sport socks online.

Krasniak was skeptical the socks would sell — until the first batch sold out in two hours.

“In one day, we had a business,” Krasniak says in a new video from the Postal Service.

The 2-minute segment is the latest installment in the “In Conversation With” series, which highlights USPS business customers.

Krasniak and Dunn used to ship orders by dropping packages into their corner mailbox, until a letter carrier offered to pick up the parcels directly.

Now the company uses the USPS shipping tools, including services that allow businesses to print labels and track packages online.

“It just makes the whole process easier,” Dunn says.

The Athletic plans to keep doing business with the Postal Service.

“We haven’t grown to our full potential, and I can’t see outgrowing USPS,” Dunn says.

The video is available on the Postal Service’s YouTube channel. Some employees may be unable to watch external videos on postal computers.
