Hermetheus Coffee

Hermetheus Coffee is an artisan specialty-coffee roaster and café in downtown Olathe, founded by Olathe residents Jason and Faith Scott. What began in 2020 as a home-roasting hobby and a globally sold roaster-automation kit grew into a brick-and-mortar shop in the lobby of the Olathe Downtown Library, built around a rare self-service roaster that lets customers choose green beans and customize their own roast.

Description

Hermetheus Coffee is an artisan micro-roaster and café operating a roughly 1,000-square-foot shop in the lobby of the Olathe Downtown Public Library, near the front entrance.¹² The café offers drip coffee, lattes, mochas, fresh-roasted beans for home brewing, and grab-and-go pastries — described by owner Jason Scott as a “scaled-down version” of the planned full menu that rotates over time.¹ The shop’s centerpiece is a rare self-service roaster: customers choose green, unroasted beans (such as Colombian or Ethiopian), select a roast level on a touchscreen, and watch the roast happen on site.³⁴ The business ethically sources Grade 1 specialty beans and roasts them in a separate Olathe facility, running a fleet that includes Valenta 3, Artisan XL, and Valenta 18 machines.²

Ownership and history

Hermetheus Coffee was launched in 2020 by Jason Scott — a former teacher and self-taught engineer — and his wife, Faith Scott, as a home-based coffee roaster selling beans online and at city events.¹⁴ Scott developed the Hermetheus Roaster Co-Pilot, an automation kit that controls heat during roasting; the original system released in 2022, followed by a Co-Pilot Pro in 2025 with Wi-Fi connectivity and hardware upgrades.² The Scotts became regular vendors at the Olathe Farmers’ Market before opening their first brick-and-mortar shop in the Olathe Downtown Library in the first week of February 2025.¹ Scott has described the move as following a passion for people: “The interaction with the people is actually what drives me.”⁴ In December 2025, Hermetheus acquired Coffee Crafters, an Idaho-based fluid-bed roasting equipment manufacturer whose Valenta machines the Co-Pilot was built to control.²
