As Amplify scaled from 6 to 60 employees, they faced new challenges in maintaining their lean product design approach. When small, they emphasized sketch-to-code pairing and a tight collaboration using tools like a design wall. As they grew to 25 employees supporting multiple products, they adopted tools like flat UI, style tiles, and icon fonts to standardize design while allowing for flexibility. With 60 employees supporting many schools, they focused on a lean mindset with goal-oriented teams, embedded designers, and problem definition workshops to continue evolving products rapidly based on learning.
