#40: "GenAI as the Sidecar" Strategy

OSS.fund Newsletter • 0 implied HN points • 11 Dec 25
🕹 Technology AI Governance Enterprise AI Systems Architecture Regulatory Compliance Workflow Automation
  1. Keep a deterministic "spine" that owns final decisions, accountability, and traceability, and treat GenAI as a sidecar that proposes or drafts but never makes binding choices.
  2. If an action creates legal obligations, liabilities, or regulated communications, the spine must execute it; tasks that involve reading, summarizing, drafting, or routing can live in the sidecar under supervision.
  3. Make evaluation continuous: use pre-deployment tests, shadow mode, production monitoring for drift and errors, and strict change control with versioning and rollback to keep the system safe.

#41: 2026/27 Budget: CIO, Will the CFO Walk You Out?

OSS.fund Newsletter • 0 implied HN points • 18 Dec 25
🕹 Technology AI Cloud IT Management Budgeting Governance
  1. Combine Run vs Change with AI vs Non-AI when allocating budget so AI isn’t siloed; set portfolio ranges and rebalance regularly.
  2. Treat much cloud OpEx as effectively committed spend and actively manage committed vs variable budget. Keep enough variable budget to absorb shocks and make FinOps and governance real before the CFO enforces them.
  3. Use guardrails: keep most work incremental and reserve step-change bets for Change+AI, treating Run as efficiency and Change as growth. Require controls, fallbacks and audit trails for customer-facing AI, and advance autonomy gradually from recommend to assist to execute.
