From ‘simple’ origins comes Cool Beans Coffee Co.

MARSHFIELD – As if her other two jobs didn’t keep her busy enough, Savannah Hildebrandt said she and her husband, Hunter, recently decided to open a mobile coffee trailer, Cool Beans Coffee Co.

“Our first day was April 25 as a soft launch, and then we never did an official grand opening,” she said. “We just accidentally went right into it and started doing random pop-ups because we had the time and the capability to do so.”

By day, Hildebrandt said she works as an office manager for a local dental office in addition to helping with Hunter’s business in their hometown of Spencer.

“He owns Hildebrandt Concrete Plus,” she said. “I do his payroll, and then some of the books alongside our CPA.”

Regardless of her already busy schedule, Hildebrandt said her and Hunter’s love of coffee inspired her to take on a new part-time venture.

“I don’t have any plans to change my current workload, which sounds kind of insane and crazy,” she laughed. “I do love the office I work [in] and the people I work with, and I’ll forever have my hand in Hildebrandt Concrete, but at this point, I’m still okay with juggling the three [jobs] – and it’s working out somehow.”

Not only is it working out, but Hildebrandt said in the short time Cool Beans has been operational, it’s already established a following.

“Every day, no matter where I am – whether it’s in Marshfield or Spencer – I have the same followers who come, people I’ve never met before,” she said. “I have people who recognize me, [and] I recognize them. They’re complete strangers, but they’ve been with me since the first launch, and they show up to every event. It’s really special.”

Mobility = flexibility

Hildebrandt said the story of how she and Hunter came to open Cool Beans is “actually so simple.”

“We just love coffee so much,” she said. “Our day has to start and end with coffee, and we love traveling. Every time we travel, we make sure we find the most quaint or quirky coffee shops we can possibly find… It’s one of our favorite parts of the vacation.”

While contemplating some “different business moves” last year, Hildebrandt said she and Hunter stumbled across a mobile coffee trailer for sale on Facebook Marketplace.

“My husband [said], ‘What if you do this?’” she said. “We talked about it for about a month or two [before I said], ‘Let’s do it.’”

Though an admittedly “impulsive” decision at the time, Hildebrandt said she believes she eventually would have started a business, regardless.

“I [didn’t necessarily] think I would have ended up here today, but [knew] I would have ended up in a situation of owning my own business someday,” she said. “It was just a matter of how, when and what exactly it was, but the mobile trailer spoke to me so clearly.”

The flexibility afforded by a part-time, mobile coffee trailer, Hildebrandt said, was a selling point.

“Managing your own time is so easy with a mobile unit,” she said. “I’m not dedicated to a building I have to pay for, [I don’t have to pay] employees or work seven days a week. I can have my life and have my other two jobs.”

Purchasing the coffee trailer in February, Hildebrandt said she and Hunter waited until after their soft launch to fully renovate the interior.

“We just [decided to] leave it with its original bones…, [then] we’re going to write down everything we need to change [it] to fit our needs when it comes to serving,” she said. “We had our soft launch on a Saturday, and that Sunday, we went to Menards and picked up a ton of lumber [to build] shelves, cabinets and organizers.”

Seasonal trailer, winter opportunities

After its initial month in business, Hildebrandt said she’s identified a couple of key areas to improve heading into the summer.

“I’ve learned a lot about the trailer and what capacities it has,” she said. “For instance, there’s no way I could operate for an entire day due to the water storage we have. That’s something we are going to be upgrading already, because I want to join events like the farmers markets, but their hours of operation are so long.”

The limited space afforded by the trailer, Hildebrandt said, has also presented early challenges.

“I went through five gallons of milk today, and a gallon of milk takes up a large portion of your fridge,” she said. “Limited space comes with the name of the game when you have a mobile unit, so that’s a learning curve, but everything else has been amazing.”

Hildebrandt said Cool Beans’ menu was curated through “a ton of trial and error.”

“Every single day before work, [I was] making [coffee] out of my garage while we were building this Cool Beans company,” she said. “[My] coffee bean roaster [is] local to Wisconsin… They’re from Hayward, and they were probably the first coffee beans we tried – they blew everyone else out of the water.”

A recent, popular addition to Cool Beans’ menu, Hildebrandt said, is dirty sodas.

“Those are such a hit – I’m obsessed with them,” she said. “I’m such a coffee person, and I’m drinking more dirty sodas than I am coffee right now, because they are so good.”

With hopes of booking additional events and pop-up locations throughout the summer, Hildebrandt said Cool Beans’ mobile operation will be “more or less seasonal.”

“My trailer isn’t set up to be winterized,” she said. “I am lucky enough to have an in with people who said I can set up shop with them in the winter for a couple of days a week if I’d like to. So, I’m juggling that idea, because then I can keep Cool Beans alive for the winter.”

Regardless of where she’s serving coffee, Hildebrandt said she and Hunter are simply excited to continue Cool Beans Coffee Co. down the road.
