Flagging before drafting: this is a Series A venture funding round, not an M&A transaction — it doesn't belong in the Top 10 Transactions format (no acquirer/target structure, no transaction value in the M&A sense, just capital raised). Per our standard flags, this should likely be excluded from the sector recap or moved to a separate venture-funding note if you're tracking those.
