Lissa Minkin joined hardware company Tile in January 2018 after a disappointing holiday season that left the company scrambling financially. Her first order of business as the new VP of People and Workplace was to fire 30% of the startup's staff. As an HR veteran with experience at Facebook and eBay, Minkin then set out to rebuild trust among Tile's remaining employees and improve the company's culture. In a conversation with Business Insider, Minkin said the biggest mistake founders make once their companies enter high-growth stages is trying to let the culture happen on its own.
