There is no portfolio tool for figuring out which AI use cases inside a company actually justify their token spend. Enterprises are seeing their Anthropic and OpenAI bills climb, and the answer isn't more compute — it's identifying which 10% of features pay back. This needs to be a real product: usage-tier tracking, ROI attribution per use case, recommendation of what to cut. Datadog-shaped tool, AI-cost-shaped problem.

There is no system-level sandbox primitive for AI agents. Agents shouldn't have ambient access to your machine — they should run in scoped environments with explicit files, limited capabilities, controlled network. Unix already has chroot and LXC for processes. Need the same abstraction for agents, plus reliable snapshot/rollback with a diff-like interface after each run. Git is the wrong layer because it's repo-scoped while agents touch files, processes, and system state.

Multi-agent setups need a "shepherd" layer that sequences agents so they don't step on each other. Right now if you run agents in parallel they hit merge conflicts and nobody resolves them. The architect-agent framing helps but something is missing — a coordinator that knows what's running, what's queued, and what needs to wait. Production multi-agent systems will require this primitive before they scale.

Couples need a unified finance tracker that pulls accounts across both partners and across platforms — Fidelity, Vanguard, work-sponsored 401k, brokerage. Mint is dead, Monarch and Copilot are individual-focused. The shared-financial-life version that handles two people with separate logins on six different brokerages is missing. Wealth advisors do this manually for high-net-worth clients; the prosumer version isn't built.

A Claude subscriber wants to see exact dollar cost per prompt and session, not just vague "you've used X% of your limit." When the model behavior shifts (4.7 burning more tokens than 4.6), users want clean attribution: which conversations cost what, which thread blew the budget. This is a thin app on top of the Anthropic API, but no first-party version exists, and Claude's own UI obscures the math.

A modern "music maker game" — create tracks in-game, upload to a server, other players listen, vote, remix. The lineage is MTV Music Maker and RaveEJ from the early 2000s. Music creation games died because nobody connected creation to social distribution. The TikTok-era version would be huge for casual creators who want to make beats without learning Logic Pro.

A virtual race app for treadmills, stationary bikes, and rowing machines. Zwift exists for cycling but the cross-modal version that lets you race friends across machine types is missing. Peloton's competitive features are siloed inside their hardware. The opportunity is the open layer that pulls heart rate, cadence, and pace from any sensor and runs a unified race.

A mood board app that takes a verbal idea and assembles visual references for non-designers. Pinterest is too noisy and requires you to know what to search for. The user describes the feeling — "fashion thing, kind of editorial, kind of moody" — and the app curates and arranges. Could be a Claude Design adjacent tool that generates the boards rather than searches existing images.

A unified app for the latest UK NICE clinical guidelines plus historical version diffs. Currently a clinician has to scrape the website and manually compare. The opportunity is push-notifications when guidelines change, structured diff against the previous version, and ability to filter by specialty. Niche but with high-value users (NHS clinicians, locum consultants).

A Tesla Live View save button for the iOS app. Currently dashcam clips only auto-save when Sentry triggers — there's no way to manually save a moment from the live feed. Drivers want to capture interactions they witness on the road that don't trip the algorithm. Tesla won't build this fast; a third-party companion app could mirror the data and save on demand.

A Twitter feature: prevent strangers (people you don't follow with private accounts) from quoting your tweets. Currently anyone can quote-tweet you, regardless of mutuality. Users want a stricter graph control — quoting requires follow-back or public account. Twitter Premium could ship this; nobody else can. But the demand signal is there and growing.

A code migration agent specifically for porting React landing pages to Next.js or Astro. Generic AI coding tools handle this poorly because they don't understand the routing, image-optimization, and SSR-handoff patterns. A Claude Code skill or standalone agent that reads the source repo, plans the framework move, and outputs a working PR with all the platform-specific patterns correct would save days of manual work.

A "subscribe to an influencer's content feed" service — pay monthly, get exactly the posts, articles, videos they're consuming in real time, before things go viral. The pitch: ghost account inside your favorite expert's algorithm, browsing their inputs not their outputs. Legally complex but the demand is clear, and a creator-opt-in version (Substack-style) is plausible. The "I want to read what Marc Andreessen reads" market is real.
