Zip Recruiter, until they fail also. I honestly use the ads in my podcasts as a way to know what companies not to invest in. Anyone want a used Quip toothbrush or some Me Undies?
Good thing you didn’t buy an Audible subscription, or use an Epson printer, FreshBooks invoicing, LastPass. Other podcast ads I’ve heard are for AmEx, Deloitte, LinkedIn, various conferences and educational institutions, and more. I agree that certain names always show up, but I’ve also been quite surprised over the years by who’s enlightened enough to advertise in podcasts. I’ll admit, though, I never did buy that Harry’s shaving kit. ;-)
I was just about to post the same thing. Clearly a lot of companies do negative-EV blanket podcast advertising to juice their customer numbers before an IPO. Sonos was another famous example (although I like Sonos a lot). There's no way ZipRecruiter is getting payback from their insane ad spend.
