From MSP security tools to healthcare bureaucracy killers, here's what's actually underserved.
Operations is unglamorous. It's the part of software nobody wants to think about until something breaks at 2am. Which is exactly why it's full of real problems that real companies will pay real money to solve.
These five ideas came out of validated demand signals — Reddit threads with hundreds of comments, G2 reviews nobody asked for, and GitHub issues where engineers are visibly frustrated. I've ranked them from good to great, with the strongest opportunity last.

High-Throughput Distributed Job Scheduler (hosted)
Here's the problem in plain terms: if you're running an ad-tech platform or IoT fleet and need to fire 50,000 scheduled events per second with predictable latency, your options are all bad. AWS EventBridge has unpredictable p99 latency. Temporal is built for durable workflows, not ultra-low-latency triggers. Kubernetes CronJob will overload etcd. So teams end up hand-rolling custom Go schedulers using timing-wheel patterns and spending months on infrastructure that isn't their product.
The architectural insight here is real. Timing wheels (documented since Varghese & Lauck, 1987) eliminate the coordination overhead that kills queue-based schedulers at high throughput. Building a hosted service around this pattern, with p99 SLA contracts instead of best-effort delivery, would fill a genuine gap. LMAX Disruptor GitHub issues are full of engineers building this exact thing from scratch.
Why is this ranked fifth? The TAM is uncomfortably narrow. We're talking about teams needing 10k+ TPS scheduling who can't build in-house and won't self-host an open-source solution. That might be 500 companies globally. One senior Go engineer can write a timing wheel in a week, and AWS could ship a high-throughput EventBridge tier at re:Invent and end the party. If you're going to build this, the window is short and the ICP is small. Worth exploring, but eyes wide open.

Developer Tool Governance & Enforcement
The Postman banning thread on r/programming (407 upvotes, 195 comments) tells you everything. Enterprises are already banning developer tools. They write the policy. They announce the policy. And then nothing enforces the policy. Postman keeps running in CI. The banned NPM package keeps getting installed. IT finds out in the next audit. Everyone shrugs.
The gap isn't awareness or policy writing — it's the runtime tripwire. MDM tools can block desktop apps but they're blind to CLI tooling and cloud-based services. SaaS management platforms like Torii or Zylo can see what's being used but can't block it in a GitHub Actions workflow. This product would sit in CI/CD pipelines and package manager hooks, failing jobs that use non-approved tools before they reach production. Deep embed, real enforcement, SOC 2-ready audit logs that become part of the official evidence package.
The risk worth taking seriously: Harness or GitHub itself could ship this. GitHub Advanced Security already charges $49/user/month and already lives in the repository. An 'approved tools' enforcement tab is not a long feature away. You'd need to move fast, get into GitHub Marketplace, and build compliance-specific audit formats that the platform players won't bother with for a niche. Mid-market fintechs and healthtechs (100-500 developers) are the right first target — fast enough procurement cycles that you can close deals before enterprise security requirements eat your runway.

Legacy Server Isolation Orchestrator (MSP Micro-Segmentation)
OT ransomware incidents are accelerating and MSPs are the ones getting the 3am calls. When a legacy PLC or SCADA device gets compromised, the containment playbook is: log into each firewall console separately, write manual ACL rules, hope you got all the subnets, document it somehow for the insurance carrier. For an MSP managing 30 client sites, that process takes 3-6 hours. An incident that should be contained in 20 minutes becomes a full breach because the tooling doesn't exist.
Illumio and Guardicore are enterprise products with enterprise pricing and enterprise complexity — they weren't built for an MSP managing mixed Fortinet and SonicWall environments across 30 SMB clients. The genuine gap here is multi-tenant orchestration: one dashboard that knows about all your client firewalls and can push isolation policies across all of them simultaneously using pre-validated templates. Flat per-MSP pricing matters too. An MSP's margin gets destroyed by per-device or per-client fees.
The liability question is worth thinking hard about before writing a line of code. If a misconfigured isolation policy fails silently and a breach spreads, the MSP gets sued and names you as a defendant. E&O insurance for a tool that makes active changes to production networks costs real money and might have gaps. You'd want iron-clad ToS, a mandatory pre-push simulation that shows predicted traffic impact, and good legal counsel before your first paying customer. The distribution is actually clean though — r/msp has 150k members and MSPs actively discuss this exact pain. Five paying customers at $199/month before you write code is an achievable validation bar.

Infra Change Sandbox & Dry-Run for AI Proposals
There's a Reddit post about an Amazon service getting taken down by an internal AI coding bot that got 1,537 upvotes and 171 comments. The comments are full of engineers sharing near-miss stories and asking, directly, why no guard rail exists for this. That's about as clean a demand signal as you'll ever get.
The problem is real: `terraform plan` shows you what will change but doesn't simulate runtime effects or multi-service interactions. An AI agent that deletes and recreates an RDS instance doesn't look obviously wrong in a plan output until you notice the `forces replacement` tag and realize that's a production database with no downtime window. A GitHub Action that provisions an ephemeral sandbox, runs smoke tests, scores blast radius, and comments on the PR with a human-readable impact report — and only blocks merge on high/critical risk scores — would be genuinely useful and genuinely missing from every team's CI pipeline right now.
The adoption path is smart: open-source the GitHub Action with a permissive license so DevOps engineers can install it in 10 minutes without procurement approval, then charge for the SaaS dashboard, custom OPA policies, and compliance reporting. The data moat builds over time — every AI-generated Terraform diff that runs through the system teaches the risk model what 'high blast radius' actually looks like across real infrastructure patterns. Spacelift and env0 could build this (they have the primitives), but they haven't, and being first in GitHub Marketplace with 1,000+ stars before they respond is a defensible position. The credential security architecture matters enormously — the GitHub Action must run entirely in the customer's own cloud account. No IaC state or credentials should ever leave their VPC. Make that the design constraint from day one, not an afterthought.

Patient Assistance Program Auto-Apply
This one is different from the others. It's not a developer tool. There's no technical moat from a clever algorithm. But it might be the most important problem on this list, and the business logic is cleaner than it first appears.
Here's how it works today: a patient gets prescribed Keytruda or Dupixent, the list price is $8,000/month, their insurance denies it or they have no coverage, and somewhere in the hospital there's a financial counselor who knows that the manufacturer has a patient assistance program that could cover it entirely. That counselor then spends 2-3 hours filling out paper forms, calling manufacturer hotlines, tracking down income documentation, and praying the application doesn't get rejected for a missing field. They do this for dozens of patients. There's no software for it. SimpleFill does it with human labor over the phone and charges for the service, which tells you there's willingness to pay.
The buyer insight is what makes this work: the patient gives up on the process because they're sick and the forms are brutal. The counselor doesn't give up but they're drowning. The hospital has a budget and a direct financial incentive — every approved PAP application is drug costs that don't end up as a billing write-off. Build a B2B tool for the counselor, not a consumer app for the patient. The product is: patient profile intake, instant eligibility match across the top 50 high-cost drugs, auto-filled application with a human review queue, and status tracking with automated follow-up alerts for missing documents.
The operational reality is that this isn't pure SaaS. Manufacturer PAP eligibility rules change quarterly without notice — income thresholds shift, drugs get added and removed, documentation requirements change. You need a part-time pharma benefits specialist to maintain the database from month one. Budget for it. The HIPAA compliance setup (AWS BAA, healthcare attorney for the BAA template) needs to happen before you touch real patient data, not after. None of this is fun, but it's also exactly why nobody has built this well yet. The market is ~6,500 FQHCs, 900 cancer centers, and 3,000 safety-net hospitals in the US alone. At $249/month per clinic, 1% penetration is $16M ARR. That's a real bootstrap outcome.
The path to first customers is concrete: search LinkedIn for 'financial counselor oncology' and 'patient assistance coordinator FQHC,' send a 90-second Loom showing the manual form pain, offer to process five real applications by hand for $200/month during the pilot. If three counselors say they'd pay $99/month after seeing it work, you have something worth building.
