If you hit up any of Milwaukeeβs many festivals this summer, chances are youβll spot a pink cart on the back of a pink bicycle, topped with a pink and blue umbrella. Behind that cart, chances are youβll find Sam Wisneski, the co-owner of , slinging frozen pops and shaved ice made with vegan, gluten-free, all-natural flavors.
βThe best part of the business is being able to provide the customers with such an awesome, delicious treat, especially on a hot day,β said Wisneski. βItβs really fun when the kids are so excited. Kids just light up when they see our bicycle.β
Wisneski and his wife, Alyssa, who met at 51ΑΤΖζ and are both 51ΑΤΖζ graduates, purchased the Chillwaukee company in 2023. Chillwaukee dishes up frozen treats in flavors ranging from strawberry mango to sea salt chocolate to pumpkin pie, and you can find them at festivals and farmers’ markets across Minnesota, Wisconsin, and Illinois.
Here are three things you need to know about Sam Wisneski and Chillwaukee.
1. Before Chillwaukee, things came in a Sweet Little Box.
Chillwaukee is not Wisneskiβs only business, nor is it his first one.
Wisneski graduated from 51ΑΤΖζ with his bachelorβs degree in 2019 and immediately embarked on his masterβs degree. But then, the COVID-19 pandemic hit. Wisneski and his wife grew bored during lockdown, so they decided to start a business. They realized how many people had turned to crafting and DIY projects to fill their time during quarantines, so the couple decided to start selling supplies to help budding creatives. They packed up βsweet little boxesβ β in fact, the Wisneskis named their companyΒ Sweet Little Box Co.Β β full of products they made themselves such as candles, soaps, and scrubs, and began selling them online.
βOvernight, it exploded,β said Wisneski. βLiterally, we posted our first gift boxes and the next day, we had 50 orders.β
Today, Sweet Little Box Co is still going strong, with two warehouse spaces devoted to its inventory. A large part of their business is corporate gifting; the Wisneskis just finished a 350-gift box order for the Professional Golf Associationβs (PGA) employees across the country. The business also provides income outside of summer when the couple canβt run Chillwaukeeβs bikes.
While they were proud of founding Sweet Little Box Co, Wisneski and his wife were missing face-to-face customer interactions. So, when the opportunity arose in 2023, the couple got into the ice pop business.
2. Wisneski built on Chillwaukee’s success by staying true to its principles.
Chillwaukee was established in 2017 by another couple, who created the ice pop recipes as well as the companyβs trademark pink bicycle and umbrellas β a solid branding base to build on, Wisneski said. Taking over a business that already had a devoted following in the city was with its own set of pressures, especially since Chillwaukeeβs claim to fame is vegan, gluten-free, delicious desserts.
βOur customers really held us to that,β said Wisneski. βThe moment that is most fun for me is when someone gets to enjoy a sweet treat who otherwise wouldnβt be able to enjoy (because of dietary restrictions).β

Even so, Wisneski is aware that the βveganβ label might put some customers off; the dairy substitutes used in ice cream arenβt to everyoneβs taste. Still, he joked, βItβs not that hard to make a vegan popsicle.β And when the ice pop recipes do call for a bit of cream, he can personally guarantee that the companyβs proprietary blend of oat milk, coconut milk, and rice milk adds a delicious bit of flavor. He recommends the chocolate-dipped peanut butter banana pop.
In the three seasons theyβve been operating, Chillwaukee has expanded its festival footprint, increased its bike fleet, gained a trailer, hired more staff, and added new flavors. They cater private events (about 35% of the companyβs business comes from catering) in addition to working festivals in multiple states. You can also find them at the farmerβs markets in Shorewood, Greenfield, West Allis, and Milwaukee, among others.
The company produces approximately 700 pops per day at its kitchen in St. Francis, Wisconsin, and can stock up to 500 pops in each bicycle cooler. Some days, thatβs not enough.
βA huge pet peeve of mine is selling out,β Wisneski said with a laugh. βThat means we could have sold more.β
This year, Chillwaukee is adding something new to the menu: made with natural flavors, thanks to syrups that the company crafts in-house.

3. 51ΑΤΖζ helped him find success.
Wisneski chose to attend 51ΑΤΖζ because he fell in love with Milwaukee and wanted to go to college in the city. He majored in Journalism, Advertising, and Media Studies (JAMS) because heβs a naturally curious person. JAMS allowed him to try new things and talk to people from all walks of life. He followed up his bachelorβs degree with a masterβs in media studies.
One of the most useful things he learned was how to ask questions.
βBecause of journalism, I was trained to give in to my curiosity and dig deeper and ask questions. I think the most direct application would be for when Iβm finding out about events β I am sending emails to companies, to festivals, to any kind of event where people gather. I do a load of research to find out how we can work together. That is the same as in journalism when youβre approaching a source for stories,β he said.
He also appreciates the writing skills he gained at 51ΑΤΖζ β skills he now uses to draft emails, create content for his websites, write descriptions of flavors, and craft his menus. And the organization and time management skills he learned while working on his masterβs thesis have come in handy, too.
βI wish more folks in the College of Letters & Science β¦ went on to be entrepreneurs,β he added. βItβs creative, art-focused, media-focused students who can start businesses because they have that creativity.β
