Not that difficult to monetise, dead people are not known for calling the cops for burglary and funeral homes, estate lawyers etc would pay for leads.

Given the audience on hacker news it's not even the worst thing people here do for cash because it's only one or so victim at a time instead of hyperscale. Old school artisan crime.

IIUC it's specifically for notifying the clergy, which would be a little sketchy to monetise. But the OP did say that probate firms already do this, so I'm guessing it's already a crowded market, which might make it difficult to monetise for other markets.
