Does Pexels make money?

Could you elaborate on the financial aspects of Pexels and whether or not it generates revenue? I'm curious to understand how a platform like Pexels, which offers free stock photos and videos, manages to sustain itself financially. Does it rely primarily on advertisements? Does it have premium services that users can pay for? Or are there other sources of income that contribute to its profitability? I'd appreciate any insights you could provide on this topic.
