Three wedge themes stand out this week. First, agent coordination tooling is maturing fast, with Foremerge, AgentRun, and Radix each carving out a specific layer of the multi-agent stack rather than competing on the full platform. Second, vertical no-code builders are finding traction by picking one industry and one workflow, as Ekselio does for finance and PlaceCall does for business outreach. Third, lossless and auditable data layers (Lossless-memory, Ive Sent It, AI-rete-RAG) point to a growing founder bet that users want AI tools that preserve full fidelity rather than compressing or abstracting their data.
