How is the PMM team structured at Figma by product line, segment, by function or by objective (ie. revenue retention, product engagement, etc)?

Philosophically, I'm a fan of a "full-stack" PMM model where they look after their product area end-to-end. We have one product at the moment, so our PMMs are aligned by areas within our product. One of our PMMs look after our Editor, Prototyping, and Community product areas—essentially making sure Figma works amazing for today's designers and the next generation of designers. The other PMM looks after our Collaboration, Enterprise, and Design Systems product areas. In other words, how does Figma work across teams at large organizations who need to scale their design processes? We have a 2.5:1 PM/PMM ratio at the moment and I'd like to maintain that over time as we grow. 

Outside of the traditional PMM role, "PMM" has a slightly more expansion role at Figma. We also have marketing manager who looks after our Education segment, as that's a special segment for us. Our customer marketer is also part of the "PMM" team as we all work very closely with our customers.
