Jellyvision has grown–and changed–a lot since it launched in 1989 as a video game company. It created the popular 90s CD-ROM trivia game “You Don’t Know Jack,” but pivoted the business into two separated companies: Jackbox Games and Jellyvision Lab, the fast-growing employee communication platform.

Today, Jellyvision has built an employee communication platform called ALEX, which helps workers understand complex things like signing up for healthcare coverage. Its humor-driven approach makes things like complicated benefits programs easier to understand, and its software is used by more than 800 companies, including over 80 of the Fortune 500. Jellyvision raised $20 million in March from private equity firm Updata to reward longtime employees and seed investors that were looking for liquidity.

Jellyvision moved into its Lincoln Park headquarters (848 W Eastman St.) in the mid-90s, and at the time took up just one office suite. Today the company takes up nearly the entire building, and has built a mini-campus in the North Side neighborhood by moving into a second building across the street in 2015, and it plans to be in a third nearby building this fall.

All in all, Jellyvision will have almost 40,000 square feet of space to house its 380 employees (the company has added 100 just in the past year).

Jellyvision’s office mirrors its company culture. There’s a splash of humor (one area has a picture of a half-naked Jellyvision employee, which was part of an art auction put on by Jellyvision to raise money for the Ronald McDonald house. CEO Amanda Lannert purchased the picture for the office), but there’s also plenty of space to get to work, like conference rooms, open work spaces and lounge areas.

The office also has privacy spaces for things other than work–like rooms for prayer and new moms–a game room, two kitchens, a band practice room, and conference rooms with names like The Olmec, a reference to the popular Nickelodeon show Legends of the Hidden Temple.
