Hyman's idea came from long nights spent studying in libraries without convenient access to freshly brewed coffee.
"I thought, why doesn't a mobile coffee maker exist? Why can't I brew coffee right here at the desk I'm studying at?" Hyman told CNBC.
So in February 2015, Hyman along with co-founder Alexandre Wing launched Mojoe Brewing Company.
"From the outside, Mojoe looks a lot like your standard travel thermos: Inside, it's a fully functioning coffee maker, taking you from water and grounds to fresh, piping-hot coffee or tea," said Wing.
Mojoe harnesses steam to extract and brew coffee directly inside the device. Just add coffee grounds to the filter, any temperature water, and power up via a wall outlet, car adapter or rechargeable battery.
The Mojoe mobile brewer retails for $89.99 on the company website. The start-up also offers its own brand of coffee in the form of To-Go Cups, which fit directly inside the brewer and are available through a monthly subscription starting at $9 per month.
To date the start-up has presold 1,211 units of its Mojoe mobile brewer, due out in November.
