"Find a problem worth solving" is the first instruction every founder gets, usually with no second instruction about where problems live. Here are twenty, from our database of 11,141 complaints that paying users left about software they already use — each with the numbers, the person who has it, and why it stays unsolved. They cluster into five families, and the families matter more than any single entry: they recur in almost every category we scan.

Family 1: "I can't learn it without help"

  1. PDF tools buried in menus — 277 complaints, 6 products. Office workers, not designers. Persists because vendors ship features, and menu rearrangement sells upgrades. → onboarding layer for Acrobat power users
  2. AI writing tools drowned in features — 117 complaints, 10 products. The largest AI pain point we track. → three ideas built on it
  3. Analytics too complex for non-experts — 110 complaints, 5 products. Marketing teams who can't self-serve a report. → plain-English report builder
  4. Video conferencing nobody can self-learn — 110 complaints, 7 products. → quick-reference cards sold to EAs
  5. Vector software too hard to start — 88 complaints, 3 products. Would-be designers bounce in the first hour. → vector graphics ideas
  6. HR reporting that requires training nobody gives — 204 complaints, 4 products. Payroll admins. → plain-language report builder for ADP

Family 2: pricing that punishes the customer

  1. Per-seat pricing that taxes growth — 155 complaints, 5 products. Ops teams pay more for succeeding. → cost forecaster, access billing layer
  2. Opaque managed-database bills — 74 complaints, 6 vendors. Engineering leads explaining invoices they can't predict. → DBaaS cost forecasting
  3. Paywalls with no visible boundary — 77 complaints, 8 photo editors. → transparent cost calculator
  4. Subscriptions forced on occasional users — video editing (71 complaints), SEO tools (8 products), surveys. → pay-per-report SEO, survey credits
  5. Billing nobody can decode — 70 complaints about ADP alone. Small businesses. → Core HR ideas

Family 3: support that never comes

  1. HR support that resolves nothing fast — 433 complaints, 3 platforms. The single biggest pain point in the database. Persists because customers are locked in by payroll migration costs. → escalation playbooks
  2. Expense support that's slow when money is on the line — 51 complaints, 4 tools. → after-hours support desk
  3. Half-baked event software with no support at showtime — 20 complaints, 5 products. Event planners have unmovable deadlines. → on-call event tech support

Family 4: software that breaks under real work

  1. Engineering simulations that crash and exhaust hardware — 46 complaints across 19 products, the most widespread pain point we track. → burst compute, checkpoint & recovery
  2. EHRs freezing during clinical work — 18 complaints, 4 products. Clinicians lose patient-facing time; hospitals negotiate contracts blind. → crash log service for EHR negotiations
  3. File conversion that dies under load — 21 complaints, 11 products. Legal and accounting back offices. → cloud batch conversion
  4. ETL pipelines that fail silently — 15 complaints, 5 products. → checkpoint-based recovery

Family 5: the platform gap

  1. Frontline workforces stranded on desktop software — engagement platforms (6 products), field sales CRMs, on-call database tooling. → pulse surveys without computers, mobile database monitor
  2. Mobile versions crippled versus desktop — 63 complaints, 7 photo editors. → mobile batch editing for photographers

How to read a list like this

Three tests separate a problem worth your year from a mere annoyance. Breadth: a complaint across many products (CAE's 19, file conversion's 11) is structural — no vendor can fix it with one release. Budget: the person complaining must control money or influence it; payroll admins and engineering leads do, students mostly don't. Persistence: ask why it's still unsolved — the answer is usually misaligned incentives (features sell, onboarding doesn't; support costs, lock-in pays), and misaligned incentives don't fix themselves.

Every number above links to the evidence. The method for producing your own list is in the validation guide; what people are already earning from problems like these is on the receipts list.

Every idea above links to its evidence page — the products the complaints came from, how many people said it, and what would have to be true for the idea to work.
