  • Early on in the process of designing Outlier, we found that many students use their laptops late at night, and don’t feel like staring into a lightbulb. Too much white in the background of videos and active learning would be fatiguing and unpleasant. We also think it’s pretty neat that we decided to do this before Apple shifted everything to dark mode.

Our team has been working tirelessly to build a product that will make world-class education more equitable and more accessible, and change the way people define excellent education.

  • Yes, and it was hard. Our instructors did extraordinary things like set up their own cinematography equipment and converted garages into sets, all while staying safe and careful.
