Ownwell- protest property tax. Is this company legit?

[Allen Wu]

All - received a marketing mailer today for my SA properties. They essentially protest your property tax and then you just pay 25% of savings. Is this legit? Or is this company a scam?

Quote from @Steve Tse:

What do they charge if they are not able to reduce your taxes ?

Their 25% fee is based on the actual property tax savings.  If they aren't able to reduce your taxes then they don't get paid.

I assume they are selective about which appeals they will take on since there is no benefit to them or the homeowner to not be able to win an appeal, but I have no knowledge of their internal business logic.
