This is a great question. Here are details from the round for those in SE Asia round"
Total amount in GR8 and GR9 are listed. GR10 did not have a round (so its more messy to calculate). GR10 we grabbed the amounts, per category, for the Grants with the region of SE Asia.
tl;dr -
$150,641 in GR8 to SE Asia Grants
$228,166 in GR9 to SE Asia Grants
$314,411 in GR10 to SE Asia Grants
GR8 to GR9 saw a big increase in total funds. GR9 to GR10 saw a mostly flat change in community funding amount. This tells me, the community did in fact support the SE Asia grants without having a dedicated matching pool as it grew at a larger rate than the total pool.
These seeds (at first glance) seem to help start communities, and after they are started, the funding is less necessary (using SE Asia as our proof point).
