Mostly a 356% increase in R&D:

  FY Ended December 31, in millions except percentage

                             | 2023 | 2024 | YoY  
  ---------------------------|------|------|------
  research and development   | $165 | $751 | 356%   
  sales and marketing        | $201 | $472 | 134%   
  general and administrative | $168 | $316 | 88%

And most of that increase came from a one-time charge from allowing employees to sell their RSUs. While not a cash cost for Figma, it was booked as an expense and allocated as follows:

                             | 2024   
  ---------------------------|------
  cost of revenue            | $25    
  research and development   | $463   
  sales and marketing        | $187   
  general and administrative | $184   
  total                      | $858   

If you subtract the one-time charge, you get:
