 ### What we learned
 
-**Event forecasting is a challenge**.  GraphQLConf 2025 underperformed in terms of sponsorship and attendance numbers.  Thanks to the conservative budgeting by the Linux Foundation’s Events team, we also came in significantly under budget, which balanced out the ledger.
+**Our event model is maturing**.  GraphQLConf 2025 gave us a clearer picture of right-sized expectations for a community-driven conference, and conservative budgeting by the Linux Foundation’s Events team meant we finished in balance.  We’re applying those learnings directly to 2026’s planning.
 
 **Carryovers are not ideal**.  The GraphQL Foundation is not a bank and should ideally not carry a large surplus year-over-year.  This is because our funds are meant to be invested into our community!  Our carryforward has progressively and appropriately shrunk over time; we are ending the year with $189,180 in the bank, a modest decrease from 2024’s figure.
