Monzo Co-Founder Tom Blomfield Takes Leave From Y Combinator to Join Anthropic

Tom Blomfield — co-founder of Monzo and GoCardless, and a Y Combinator general partner since 2023 — announced on July 13 that he is taking a leave of absence from YC to join Anthropic's compute team under co-founder Tom Brown. He said that as the industry enters the early stages of recursive self-improvement, compute availability is becoming one of the most important problems to solve, extending Anthropic's 2026 hiring run that already brought in Andrej Karpathy and DeepMind's John Jumper.

SpaceXAI Launches Grok 4.5, Claiming 'Opus-Class' Performance

SpaceXAI released Grok 4.5 on July 8, its first model trained specifically for coding and agentic work, pricing it at $2 per million input tokens and $6 per million output tokens. Elon Musk positioned it as roughly on par with Claude Opus 4.7 but faster and cheaper; independent benchmark charts released alongside the launch showed it ahead of Opus 4.8 on some tasks and behind on others.

Sysdig Documents 'JadePuffer' — the First Fully Autonomous AI Ransomware Attack

Cloud security firm Sysdig documented an extortion operation, dubbed JadePuffer, in which an AI agent handled the entire technical execution of a ransomware attack — exploiting a Langflow remote-code-execution flaw (CVE-2025-3248), stealing credentials, moving laterally through the network, encrypting files, and writing its own ransom note, adapting its tactics in real time after failed attempts. A human still chose the victim, provisioned infrastructure, and supplied credentials, but the technical attack chain ran without operator input.

Zuckerberg Tells Staff Meta's AI Agent Push 'Hasn't Really Accelerated' as Expected

At a July 2 internal town hall, Mark Zuckerberg told employees that Meta's Superintelligence Labs agentic-AI effort had not accelerated over the prior four months despite the company's restructuring, and that the reorg's benefits 'haven't come to fruition yet.' The admission followed May's layoff of roughly 8,000 employees (about 10% of headcount) and a July reassignment of 7,000 staff into AI-focused roles, against a backdrop of roughly $145 billion in planned 2026 AI infrastructure spending.

Fazeshift Raises $17M Series A for AI Agents That Run Accounts Receivable

Fazeshift, which deploys AI agents to automate accounts receivable — invoicing, follow-ups, reconciliation, and cash application — raised a $17 million Series A led by F-Prime Capital, with participation from Google's Gradient Ventures and Y Combinator. Investors are betting on AI-powered finance operations starting with AR, the transactional-finance segment where AI results have been strongest.

Chamath Palihapitiya Takes CEO Role at 8090 Labs on a $135M Raise

Enterprise AI-coding startup 8090 Labs closed a $135 million Series A led by Salesforce Ventures, with Chamath Palihapitiya moving from board member to full-time CEO. Its product, Software Factory, is an AI coding agent built for regulated enterprises (healthcare, insurance, aerospace, financial services, government), pitched on production-grade, audited code rather than prototype-quality output.
