About Firebox Spice Company

Founded in 2022, Firebox Spice Company is a St. Louis, MO based purveyor of expertly crafted rubs and spices including Rib Rub, Chicken Rub, and Brisket Rub.

Firebox Spice Company Founders Tanner Hobin and Kurt Sliefert

It all started playing poker at Steph and Kurt’s house one fall night. The gracious host that he is, Kurt, smoked a massive brisket for the entire group of guys. While others took a smoke break between rounds, Tanner slowly devoured more than his fair share of the delicious brisket. While Tanner was still stuffing his face, he uttered to Kurt, “You know you should sell this rub…”

Fast forward a few years, kids, jobs, and other life events; with the blessing of both better halves, Tanner and Kurt finally sat down to build the business. Starting with three essential rubs, they launched Firebox Spice Co in July 2022.

We are beyond pleased with the initial products and early success. More so, we are excited for what’s to come. Over the next few months and years we hope to grow the portfolio and expand into retail. We couldn’t have launched this dream without the love and support of so many, especially our wives. We would also like to thank our friends and family for their continued support and encouragement.
