## TL;DR

This week was all about safeguarding value through critical transition points, whether that means helping wealthy retirees bypass pension taxes via VaultFlow, or matching retiring European family business owners with eager PE-backed operators via Graft. We also saw a relentless push to eliminate legacy friction in consumer experiences, with NervePath using invisible biometrics to kill ticketing bots without annoying fans, and StreamShelf turning TV pause screens into instant Shopify checkouts. Ultimately, the future belongs to *highly specialized context layers* designed for hyper-niche workflows—whether you are Kontxt pruning messy APIs for token-guzzling AI agents, or Tessera orchestrating RSVP dynamics and table rotations for elite Mahjong clubs.
