grumft.com's sellers.json looks incomplete: it lists 14 sellers, while app-ads.txt files name 19 other grumft.com accounts it does not list. A line it does not list may be a seller the network never published rather than a stale line, so we show no verified or not-listed share for it.
App counts, the sellers.json breakdown and the directory ranking are as of , recomputed daily (the same numbers as the directory). Line counts are recounted every 10 minutes. sellers.json last read 13 October 2026. The supply path score sums up how short and clean the declared paths are, 0 to 100 (how it is computed).

-
Seller ID not found
40 lines
Ask grumft.com for the account ID it lists for you in its sellers.json, correct the line, or remove it if you no longer work with them. Buyers that check sellers.json drop these paths.

Seller type BOTH

The account is listed as BOTH, so sellers.json alone cannot tell a buyer which relationship applies. Nothing to fix on your side; buyers usually look at the seller's domain.
