Robinhood launched AI agentic trading in beta on Wednesday. Users can now create a dedicated subaccount for their AI agents, pre-load it with a cash balance, and connect agents via Model Context Protocol (MCP). Agents can analyze portfolios, surface analyst notes, and place stock orders — but are limited to the funds in that dedicated wallet, not the user's full account. Robinhood adds fraud review, approval previews for some trades, and real-time notifications. Options, crypto, and futures support is planned. A virtual agentic credit card for AI-triggered payments launched alongside, currently for Gold Card holders only.

Triomics, which builds AI tools for cancer centers — clinical trial matching, patient chart summarization, tumor registry filings — closed a $22M Series B led by Battery Ventures, with Nexus Venture Partners, Lightspeed, and Y Combinator also participating. The company's enterprise customer base grew fourfold in the past year, with annualized recurring revenue up 10x. Customers include Memorial Sloan Kettering and Yale Cancer Center. The differentiation: models trained on oncology data specifically, not general-purpose medical AI. The prior round was a $15M Series A in mid-2024.

Vertu unveiled the Alphafold Thursday — a foldable smartphone built around an enterprise AI agent called Hermes Agent, based on the open-source Hermes project from Nous Research. The phone connects to ERP and CRM systems and can handle approvals, scheduling, sales tracking, and operational reporting via natural-language prompts. It routes requests to GPT, Claude, Gemini, or open-source models, and integrates with 80+ apps. Hardware: Snapdragon 8 Gen 4, 8.05-inch inner display, 6,500mAh battery, satellite connectivity, a proprietary A5 security chip for on-device credential isolation. Base price is $6,880 in calfskin; the top standard configuration reaches $46,800. The first 115-unit batch ships this week across the US and other markets. Third-party security audits are not yet done.

Drew Houston, who co-founded Dropbox in 2007 and has run it ever since, announced he is stepping down as CEO to pursue an AI venture. He plans to remain on the board. No successor was named in reporting by The Verge, which noted Houston described his next project as AI-focused without specifying further. Dropbox has been cutting headcount since 2024, citing AI's effect on workforce needs, and this year announced it would not replace many departing employees. Houston stepping back marks the end of an unusually long founder-CEO tenure at a public tech company.
