Permatemp roles are more abundant and pay better. But the others are not that rare. I never had difficulty finding these roles; it's been more work turning away clients than marketing. YMMV.

Many are those are dead end projects that never get off the ground, or don't have enough budget for a marketing team and a full MVP. Many are part time founders who make good money and want to throw money at a side project, but aren't fully focused. There's a lot of downsides to the path too.
