Featured: Sierra raises $950M at $15B to industrialize enterprise AI agents
Why it matters: Mega-rounds are back for agent platforms. Budget is shifting from pilots to production, and boards want measurable ROI from AI that works across systems, not just chatbots. Sierra’s scale-up signals a crowded but accelerating race to become the default agent stack for the Fortune 500.
Sierra, co-founded by Bret Taylor and Clay Bavor, raised $950M at a $15B valuation. The company reports ~$150M ARR and traction with nearly half of the Fortune 50. Its Agent SDK bundles skills, guardrails, and connectors, running across 15+ open and proprietary models—positioning it as an abstraction layer for agent workflows spanning sales, support, and operations.
What to do: If you’re consolidating AI pilots, shortlist platforms that (1) provide auditable guardrails, (2) integrate with your identity and data layers, and (3) publish reliability metrics per task. Push vendors for agent evaluation reports, not just demos.

Microsoft takes Agent 365 out of preview to curb shadow AI at work
Why it matters: Autonomous tools are already running in many teams without central oversight. Agent 365 aims to give IT leaders visibility and controls over rogue automations, tying agent actions to identity, policy, and audit trails.

Cisco buys Astrix Security to lock down AI agents’ credentials
Why it matters: Non‑human identities (agents, service accounts, API keys) can outnumber employees 100:1. Cisco is folding Astrix into Duo/Identity Intelligence to discover agents and MCP servers, inventory permissions, and yank risky OAuth tokens—closing the gap many security teams now face.

White House weighs pre‑release vetting of AI models
Why it matters: If adopted, pre‑launch reviews could add compliance steps and longer vendor timelines for new foundation models. For regulated industries, it could also make approved models safer bets for audits and procurement.
According to Reuters reporting cited by CNA, the administration is discussing an executive order to convene a joint industry‑government group to design oversight procedures before models go public. This reflects a broader pivot from non‑intervention to structured guardrails after recent model capability surprises.

Cerebras targets $3.5B IPO at $26.6B valuation; OpenAI and AWS deals in play
Why it matters: More compute suppliers = more leverage on price and delivery for enterprises. Cerebras’ wafer‑scale chips promise faster inference and a new cloud option—potentially easing Nvidia dependency for certain workloads.
Cerebras disclosed IPO terms and highlighted improving financials (2025 profit after heavy 2024 losses). Its WSE‑3 powers the 1.8‑ton CS‑3 system and is now available via AWS. A long‑term deal to supply up to 2 GW of compute to OpenAI could anchor future revenue.

SAP to buy Dremio and Prior Labs to supercharge tabular AI in Business Data Cloud
Why it matters: Most enterprise value still lives in rows and columns. SAP is doubling down on SQL‑free analysis and agent‑ready data prep—bringing AI closer to where finance, supply chain, and ops teams already work.
Dremio brings Iceberg/Polaris lakehouse tech plus a built‑in AI agent for natural‑language queries. Prior Labs contributes TabPFN‑2.5, a tabular foundation model. SAP says it will invest ~€1.17B in Prior Labs over four years and weave both into Business Data Cloud to improve governance, metadata, and performance.
