A sole IT admin supporting 150 people needs something to watch log files on a schedule and email an alert when it finds trouble. The specific pain is an ERP vendor whose nightly jobs — MRP, costing — can fail silently, and the vendor's official answer is "look in the log files." That's a real B2B gap: not log aggregation for a platform team with a Datadog budget, but a small, cheap, scheduled grep-and-email service for the enormous population of one-person IT departments running vendor software with no alerting. The tell is that they were about to build it with Claude and asked around first to avoid reinventing the wheel — which means the wheel isn't findable.

Vibe coders are plugging into new model APIs constantly and have no way to check whether a provider is safe. The concerns are concrete: a provider quietly serving a different model than advertised, a provider harvesting unrelated project data (the recent Grok incident is the cited example), or one manipulating the model into writing malicious code. Nobody has shipped the health-and-trust check for coding APIs, and the market is exactly the people least equipped to audit one themselves. A verification harness that fingerprints which model is actually being served and watches what leaves the machine would sell itself right now.

An EV charger that automatically detunes its output based on the total upstream load limit apparently doesn't exist. The complaint is that the "smart" side of smart charging isn't real: chargers don't throttle in real time against what the rest of the panel is drawing, so installations get capped by the service limit instead of dynamically sharing it. This is a hardware-plus-firmware gap with an obvious wedge — load-aware charging lets buildings add chargers without upgrading service, which is the single biggest cost in EV infrastructure.

Someone wants a filter to block AI-generated books on Kindle. Ebook stores are filling with generated slop and there's no way for a shopper to exclude it from search or recommendations, which is a detection problem with a very clear willingness to pay behind it. The platform has no incentive to build this — the slop is inventory — so it's a browser extension or a third-party catalog play. Note the adjacent signal: the same day, a separate builder floated flagging AI-generated content in Gmail and Slack. The demand for slop filters is showing up in every channel at once.

GitHub Actions has no warning-level check. A developer wants to mark an action's report as optional: show whether it passed, but don't fail the entire commit if it doesn't. Right now every check is binary, so teams either block merges on flaky or advisory checks or delete them entirely and lose the signal. A middle tier — informational status that reports without gating — is the kind of small primitive that CI platforms keep not shipping and that half of engineering teams work around with hacks.

Grocery and delivery marketplaces have no smoke-free shopper preference. The ask is blunt: the groceries arrive smelling of cigarette smoke, and there's no way to request a non-smoking shopper on Instacart or DoorDash. It's a marketplace-matching feature with real demand from people with asthma, allergies, scent sensitivity, or just a preference, and it's the sort of filter that gets built for every other attribute of a delivery except this one.

Video games still have no Letterboxd. The person asking has a Backloggd account and barely uses it, which is the important detail — this isn't "nothing exists," it's "what exists isn't good enough to become a habit." Films, books, and music all have a beloved social logging app; the largest entertainment medium by revenue has a handful of functional-but-unloved trackers. The gap is taste and social design, not features, which is exactly why it's still open.

A dating app that matches on behavioral signal instead of self-reported profiles. The proposal is to match on similar internet history, data usage, and the algorithms that shape what each person is shown, on the theory that what you actually consume describes you far better than what you claim in a bio. Privacy is the obvious wall, but that's also the moat — an opt-in, on-device version of this is buildable now and would sidestep the fundamental lie at the center of every dating profile.

There's no clean way to run multiple accounts in AI assistant clients. A user keeps one account for work and one for personal and has to log out and back in to switch contexts, which they rightly call a surprising deficiency for a tool that does so much else. Browsers solved this with profiles a decade ago. As these clients absorb more work-critical context — projects, memory, connectors — the blast radius of mixing work and personal accounts grows, and the switching tax gets paid many times a day.

Nobody has built the dataset of production harness system prompts. The ask is specific: title generation, chat, subagents, compaction — the system prompts that actually run inside shipped agent products. Everyone building a harness right now is reverse-engineering these one leak at a time, and a curated, open corpus would be immediately useful to every team in the space. The timing is good: xAI just open-sourced the full Grok Build agent loop, so the raw material is starting to exist in public.

3D printing has no good tool for removing support interface material. A month-in hobbyist discovered that the poor underside finish on their prints was actually leftover support interface, and the best implement in their kit is a chisel-blade hobby knife — which is currently running about 70/30 holes-in-themselves versus damage-to-the-print. Support removal is a universal step in FDM printing and the tooling is improvised from craft knives. A purpose-built tool for scraping interface material without gouging the part or the operator has an obvious, large, and already-spending audience.

Kickstarter's mechanic has never been applied to political mobilization. The idea is a conditional commitment platform: you pledge "I will attend if 4,000 others pledge to attend," the pledge count is visible, and the event triggers only when the threshold is reached — with cascading tiers, so clearing the 100-person threshold activates the people who pledged at 200. The insight is that collective action fails because nobody can see whether enough others will show up, which is precisely the problem escrowed pledges solved for fundraising. The person laying it out has researched prior attempts (PledgeBank and others) and found no serious campaign has run one.

There's no place for people to say what they like about local infrastructure. The specific version: why is there no way for users to write why they appreciate a given bike lane? Every civic feedback channel is built to capture complaints, so the record that reaches city councils is systematically negative even when most users are happy, which quietly kills projects that are working. A location-anchored tool for positive testimony about infrastructure is small, cheap, and would change the input to a lot of municipal decisions.
