Badcryptopodcast had a sponsored episode featuring the Syanpse AI founder:

There is a 100 SYN airdrop (about $10)
tokensale.synapse.ai/airdrop/badcryptopodcast
Pretty simple process with a 1 minute signup and putting in your ETH address.
I have no affiliation with badcryptopodcast but do think they have a nice show.
