Looks like Sierra’s making waves in the AI game, landing close to a $350 million round to boost their customer support agents. Meanwhile, Google’s gearing up to drop some new smart-home gear with its Gemini AI, potentially shaking up the way we chat with our devices. On the flip side, OpenAI is strengthening its hold on product development by acquiring Statsig, while Anthropic’s massive $13 billion raise and Microsoft’s new in-house models show that the race for AI dominance is as fierce as ever. With all these moves, it’s clear the big players are gearing up for some serious action in enterprise AI and consumer tech.

Sierra close to $350M round as AI agents for customer support heat up

Scoop: Sierra, a two-year-old startup building specialized AI agents for enterprise customer service, is nearing a $350 million financing round that would value the company at about $10 billion. Founded by Bret Taylor (former Salesforce co‑CEO and current OpenAI chair) and ex‑Google exec Clay Bavor, Sierra is reportedly on track to exceed $100M ARR and is doubling down on tailored agent deployments for support. Why it matters: the deal signals continued investor appetite for narrow, production-ready agent businesses (not just general LLMs), and underscores how enterprise automation and customer‑service workflows remain prime avenues for AI monetization and consolidation.

Google teases 'Gemini for Home' hardware event — new Nest Cam, speaker and more expected

Google has teased an October 1 event for 'Gemini is coming to Google Home' after introducing Gemini for Home earlier, signaling a broader push to replace Google Assistant with its Gemini AI across smart‑home devices. The teaser hints at refreshed Nest hardware (a new Nest Cam and Nest Doorbell with 2K support and an unseen Nest speaker). Why it matters: this marks a major move to embed generative AI directly into consumer hardware — reshaping smart‑home UX and intensifying competition with Amazon and Apple on AI assistants, while raising fresh questions about on‑device inference, privacy and trust.

OpenAI acquires product‑testing startup Statsig and names CEO Vijaye Raji CTO of applications

OpenAI announced it is buying product‑testing firm Statsig in an all‑stock deal (reported valuing Statsig at about $1.1B based on OpenAI’s current valuation). As part of the deal, Statsig CEO Vijaye Raji will join OpenAI as Chief Technology Officer of Applications, leading product engineering for ChatGPT, Codex and related product infrastructure. Why it matters: the acquisition brings developer‑facing experimentation tools and experienced product leadership in‑house as OpenAI doubles down on product velocity and reliability — a strategic move to tighten the loop between model capability and production deployment in a competitive AI market.

Anthropic closes massive $13B Series F, lifting post‑money valuation into the high‑hundreds of billions

Anthropic raised a $13 billion Series F (reporting shows a ~ $183B post‑money valuation) in a round co‑led by ICONIQ, Fidelity and Lightspeed with participation from a broad set of institutional and sovereign investors. The company said the capital will accelerate enterprise adoption, safety research and international expansion after a rapid revenue ramp this year. Why it matters: the scale of the raise underscores intense investor appetite for leading generative‑AI vendors and further escalates the funding and competitive dynamics among Anthropic, OpenAI and other model providers — with implications for enterprise deals, talent competition, and infrastructure spend across the industry.

Microsoft unveils MAI-Voice-1 and MAI-1‑preview — new in‑house models to power Copilot

Microsoft’s AI team announced two new in‑house models — MAI‑Voice‑1 (a very fast, single‑GPU speech generator) and MAI‑1‑preview (a text foundation model) — designed to power Copilot features in Windows and Office and reduce Microsoft’s reliance on external models. Why it matters: these models are built for cost‑efficient production use (voice generation for podcasts/briefings and text tasks for assistant features), so they could meaningfully change how developer and productivity tools (e.g., coding assistants and voice features in Copilot) are delivered and priced. The move also signals a strategic shift toward first‑party model stacks that can be integrated tightly into apps and enterprise services.

Anthropic raises $13B and highlights Opus 4.1 — a boost for coding tools and enterprise AI

Anthropic said it raised $13 billion in a Series F that values the company at about $183 billion and will fund expansion, enterprise rollouts and safety research. The company recently rolled out Opus 4.1 (an upgrade focused on agentic tasks, reasoning and coding accuracy) that’s being used across its Claude/Claude Code offerings — an important development for teams building AI coding assistants, developer tools and enterprise AI integrations. Why it matters: bigger funding plus iterative model improvements accelerate productization of tools (code assistants, agent builders, cloud integrations) that developers and companies use daily.
