Job Board Business Model: Pay per Application?

Hello Community 👋

I've been building several 'job boards' last few months and noticed that the majority of job boards charge companies on a "pay per post" basis (i.e. $299 for 30 days).

To borrow @levelsio's math, this translates to about $0.10/session - that's how much each visitor is worth when implementing a pay per post model. (Read the math here: https://wip.chat/questions/what-to-avoid-when-building-a-new-job-board)

My question is whether anyone here has had experience charging companies on a performance-based model for their job board?

One version of this model is to charge companies each time you send them an application. So rather than asking companies to invest an upfront amount for an unknown result, you could charge them every time they receive an application.

(I realize CPC is prevalent, e.g. Indeed, but does anyone have experience charging for applications not just clicks.)

Has anyone tried this and what were the results? (Equally keen to hear why you don't want/can't try it!)

...Also curious if any employers on here would find this payment model interesting versus the traditional pay per post?

Thanks !
