Late stage subscription rev businesses trading on FCF yield?

Hi, are there any sectors other than Cable where businesses trade on an FCF yield basis?

Have a business with recurring rev, high margins, but incredibly high customer acquisition costs so EV / EBITDA is nonsensical. It doesn't grow fast enough and is too capital intensive to trade on revenues, and I'm struggling to find some good valuation benchmarks.

I think FCF yield makes the most sense so am curious if people know any spaces where names trade like this or have any other ideas on metrics i might be able to look at. 

Thanks!
