A diverse team of six people engaged in a casual meeting in a modern office lounge area. They're sitting and standing around a gray sofa with yellow accent pillows against a wooden slat wall backdrop. A screen displaying the 'treehouse' logo is mounted on the wall. The group appears to be sharing a light moment, with several members smiling and laughing. The space features contemporary design elements including pendant lighting and a small indoor plant in the corner.
