Pain Mine, part one
Ten product openings pulled out of complaints across 28 subreddits
Ten web product openings pulled out of Reddit complaints. Behind each one is a specific person in a specific trade losing a specific stretch of time. The ordering is my judgement, not the output of a formula.
The sampling method first
This determines how far the ten below can be trusted.
How the sample was taken
Ranked by comments, not by upvotes
Highly upvoted posts tend to be the well-phrased ones. Heavily commented posts are the ones that hit a nerve. Within the last twelve months I read the top few threads by comment count in each subreddit, 21 in total.
The quotes are paraphrase
Not word-for-word translation
The evidence column is my summary after reading, not a rendering of the original. Upvote and comment counts are from the time of collection and have almost certainly moved. Go back to the thread before quoting anything.
The largest distortion
Reddit is not the market
People who write long English-language complaints about software on a forum skew technical, skew small-business, skew American. The demand scores below hold inside that population and nowhere else.
Five patterns that cut across industries
A complaint only counts as real demand when it shows up in subreddits that have nothing to do with each other. These five recurred most often, and the ten products below are largely facets of them.
Pattern 01
The money leaks at the handoffs
Opening a work order is easy; chasing it is hard. Sending a quote is easy; remembering to follow up is hard. Sourcing a candidate is easy; not letting them go cold is hard. Every tool on the market optimises a single step, and nobody owns the space between them.
Pattern 02
More tools, more fragmentation
SMS, WhatsApp, Instagram DMs, email, web forms, platform inboxes. A large share of the day goes on working out who is still waiting on a reply, rather than on replying.
Pattern 03
AI went after the skilled work and left the admin
What lawyers, accountants and doctors actually hate is administrative dead time, and every tool is competing to draft documents for them instead. Someone in r/LawFirm said exactly this and took the top comment in the thread.
Pattern 04
A system you have to maintain is not a system
The ADHD subreddits keep making this point: anything that requires you to enter, sort and prune it yourself dies the first week you stop. It applies to every overloaded user, not just that group.
Pattern 05
When the data disagrees, people go back to doing it by hand
Logistics, non-profits and finance all describe it identically: two systems say different things, so nobody trusts either, and everyone reverts to manual reconciliation. Validation is often worth more than automation.
Ten buildable web products
Ordered by the sequence I would build them in, weighing strength of evidence, willingness to pay, and how hard the cold start looks. That is a judgement, not a calculation, and you are free to disagree with it.
Priority 01 · Small service businesses
Quote to cash, as one unbroken line
Turn send a quote → chase it → did they open it → convert to a job → invoice → chase payment into one continuous chain instead of five disconnected actions.
Build first
- Quote templates, thirty seconds to send from a phone
- Whether the client opened it and how long they read it, written back as status
- Automatic follow-up cadence on no reply: 3 days, 7 days, 14 days
- One tap to invoice, automatic chasing when overdue
Who pays
Contractors, repair trades, photographers, wedding planners, freelance designers. People with jobs worth a few thousand each and a few dozen a year. At $29–79/month, one job that does not slip through pays for it.
Where it gets hard
Jobber and Housecall Pro already sit here and are expensive and heavy. The wedge has to be narrow enough to say I only fix the part where you forget to follow up, because otherwise your feature list will always be shorter than theirs and buyers compare feature lists.
Priority 02 · Cross-channel messaging
A “who is still waiting on me” inbox
Flatten conversations scattered across six apps, work out who is still waiting, and order them by which deal you are about to lose. No chat features.
The asset is the ranking, not the aggregation
People are not complaining about message volume. They are complaining about having to decide what matters. One phrasing that stuck: every tool helps me store them, none helps me sort them. Anyone can build the pipes. The ranking model is the part that is yours.
Build first
- Three channels only: email, WhatsApp Business, website forms
- One morning digest: the five you have to answer today
- Automatic escalation past N days unanswered
Where the engineering cost is
Channel APIs, and platform policy that changes underneath you. Ship read-only plus reminders and do not send on the user’s behalf, which sidesteps most of the access restrictions and review. That one decision halves the work.
Priority 03 · IT operations
An expiry sentinel for certificates, domains and renewals
Scan every domain and endpoint you own and watch every SSL/TLS certificate, domain registration and annual subscription for its expiry date, then wake somebody up before it bites.
Why this one
In a 382-comment r/sysadmin thread asking which specific task people hate most, certificate work was among the most-nominated. It is not difficult. It is repetitive, easy to forget, and expensive when forgotten. Those three together are the best possible shape for a SaaS.
Build first
- Take a list of domains, discover subdomains and certificate chains automatically
- An expiry calendar with tiered alerts at 30, 14 and 3 days, over Slack, email and phone
- A register of who issued each certificate and which machine it is installed on
Where the money is
Free certificate monitors are everywhere, so monitoring alone does not sell. What sells is the register and the ownership: who issued it, where it lives, who to call when it expires. The customer is an MSP running dozens of client environments, not one company’s ops team.
Priority 04 · Property management
A follow-through desk for maintenance tickets
Property software has solved raising a ticket. The time goes after that: chasing the vendor, arranging tenant access, confirming the work is done, telling the tenant it is finished.
Shape of the product
- One ticket is one timeline across three parties: tenant, vendor, manager
- Vendors update progress through an SMS link, no app, no account
- Access windows matched automatically against the tenant’s availability
- Stalled tickets rise to the top on their own instead of waiting to be found
The second thing it can absorb
Chasing late rent gets named separately in the same threads: the same phone call and the same letter every month. It is a second module on the same follow-through engine.
Where it gets hard
AppFolio and Buildium own the ecosystem and cannot be replaced head-on. The way in is as a plug-in that takes only the follow-through and reads its data from theirs. Which also means your existence depends on somebody else, and the day they ship the feature themselves you are finished.
Priority 05 · Non-profits and grant-funded work
A reconciliation desk for restricted funds
Donations, grants and programme budgets each carry their own restrictions. Line up four sources — bank feed, payment processor, CRM and ledger — sort every transaction into the right fund, and produce the compliance reporting.
Why nobody has done it well
General accounting software has no concept of a restricted fund, and CRMs have no concept of a chart of accounts. The reconciliation caught between them is entirely manual and starts over every month.
Build first
- Connect QuickBooks, Stripe and one major donation platform
- A rules engine that tags by campaign, fund and grant
- A variance list showing only the entries that do not reconcile
- One-click grant compliance reporting
Where it is slow
Long sales cycles and tight budgets; non-profit decision chains are longer than those of companies the same size. But the price point supports $150–400/month and it is extremely sticky once installed. Enter through one narrow segment — small and mid-size foundations, for instance.
Priority 06 · Professional services
An administrative layer for law and accounting firms
Explicitly does not touch professional content. It takes the chores: capturing time automatically, chasing clients for documents, filing correspondence, turning commitments buried in email into tasks.
The sharpest evidence in the set
In a 65-comment r/LawFirm thread, the top comment is not praise for any AI tool. It is a complaint that legal tech is fixated on the lawyer’s work and ignores the administration that consumes the day. Twenty-two colleagues upvoted it, which amounts to a small confirmed market gap.
Not touching content is what makes it sellable
Because it generates nothing that goes near a court, it sidesteps professional liability and hallucination risk — precisely the concern several lawyers voiced in the same thread. In a sales conversation that is the pitch, not a limitation.
Where the first users are
The same subreddit is full of lawyers building case management out of Airtable, Notion and ClickUp. They have already proved the demand by their behaviour, and their hand-built systems will collapse eventually. That is your seed list.
Priority 07 · Recruiting and sales
Follow-up leakage, measured
Does not do the following up. Quantifies where following up breaks. Connect to the ATS or CRM and compute response delay at each stage, who went cold with nobody owning them, and what it cost in closed business.
Against the received wisdom
The industry attributes lost deals to not finding people. But someone in the thread points out that plenty of losses are candidates who were found, were engaged, and then had nobody pick them up. It is a leak everyone senses and nobody measures — and something nobody measures is the easiest first version to sell.
Why measurement-only sells better
It does not require replacing the ATS or CRM, does not change anyone’s workflow, and produces numbers the day it is installed. Sales resistance is far lower than for a replacement product, and once the numbers exist, selling automation on top follows naturally.
Where the engineering cost is
Entirely in data access, and dependent on the customer’s API permissions. A legacy ATS will be painful. Support Greenhouse, Lever and HubSpot only, and say no to everything else.
Priority 08 · Personal productivity (ADHD)
An external brain that needs no maintenance
Say it out loud as it occurs to you, have it broken into small timed tasks, and pushed back at you by a reminder you cannot dismiss. One promise: you never have to maintain it.
Two hard constraints
- Reminders have to pin. A comment with 574 upvotes makes the point that once a notification is swiped away to clear the shade, the task is gone. What is needed is a reminder that only disappears on completion.
- Capture has to be frictionless. Several people say the hard part is remembering to write it down, not what happens afterwards. So the entry point has to be voice, in the moment — never opening an app to create an item.
Money
Consumer subscription at $5–9/month. The population is large and word of mouth is unusually strong; that 204-comment thread is almost entirely people recommending tools to each other. But this group is actively hostile to another to-do app, so the positioning has to be an external brain.
The one I am least sure about
The most crowded category here, retention decides everything, and I have no retention data for any comparable product. A meaningful subset of users also believe the phone itself is the source of the problem, which a pure app cannot solve. It sits at eight because the demand is the most genuine on the list and it is also the most likely of the ten to fail.
Priority 09 · Logistics and trade
Pre-flight consistency check on shipping documents
Before the goods leave, cross-check the bill of lading, commercial invoice, packing list and customs paperwork against each other, and surface the fields that disagree: weight, piece count, consignee, HS code, reference numbers.
Why it is workable
Rules plus OCR. It does not connect to anything inside the customer, so a file upload is the whole onboarding. Sales friction is therefore almost nil, and one free run proves the value — which is rare in B2B.
Build first
- Upload a document set, get back a list of discrepancies
- Cover the six to eight most common cross-document field conflicts
- Price per shipment, not per seat
The mood of the industry
This trade is exhausted by new tools; one 74-comment thread is titled, more or less, stop asking us about our pain points. So it cannot arrive as a platform. It has to arrive as one small thing you can verify immediately, and the word platform should not appear on the landing page.
Priority 10 · E-commerce and creators
Provenance for human-made work
Not an AI detector — those do not work. The inverse: let a human creator leave a verifiable record of the process, layered files, timeline, draft versions, and mint a badge they can put on a product page.
Which side the demand is on
Buyer anger is unambiguous: platform rules require AI disclosure, nobody enforces it, and buying undisclosed AI output does not get you a refund. Sellers have no way to prove otherwise. Both sides hurt, but the seller is the one who can pay, because provenance lifts conversion and price.
Build first
- Drop in a working file (PSD, Procreate, AI) and extract layers and edit timeline
- Generate a publicly verifiable provenance page and an embeddable badge
- Serve exactly one category to start: Etsy digital downloads
Why it is last
Provenance can be faked, and all it really establishes is that a plausible process took place. That sentence has to be on the landing page from day one, because if you have overstated it and somebody challenges you, the collapse in trust is instant. A product whose entire premise can be broken by one popular post is not the one to start with.
On one page
Scores are 1–5. Lower is better for build difficulty and competition. Cold start is how hard the first ten paying customers look. Every score is my judgement.
| # | Product | Buyer | Suggested price | Demand | Pay | Build | Comp. | Cold start |

| 01 | Quote-to-cash line | small service businesses | $29–79/mo | 5 | 4 | 2 | 4 | easy |
| 02 | Who is waiting on me | solo and small teams | $19–49/mo | 5 | 3 | 4 | 3 | easy |
| 03 | Expiry sentinel | MSPs and IT teams | $49–199/mo | 4 | 4 | 1 | 3 | medium |
| 04 | Ticket follow-through desk | property managers | per unit | 5 | 3 | 3 | 4 | medium |
| 05 | Restricted-fund reconciliation | non-profits, foundations | $150–400/mo | 4 | 4 | 4 | 2 | slow |
| 06 | Professional admin layer | law and accounting firms | $99–299/seat | 5 | 5 | 3 | 2 | easy |
| 07 | Follow-up leakage | agencies, sales teams | $199–599/mo | 4 | 4 | 2 | 3 | medium |
| 08 | Zero-maintenance external brain | ADHD, overloaded individuals | $5–9/mo | 5 | 2 | 2 | 5 | easy |
| 09 | Document consistency check | freight forwarders, exporters | per shipment | 4 | 4 | 3 | 2 | medium |
| 10 | Human-work provenance | digital goods sellers | $9–29/mo | 4 | 2 | 3 | 2 | medium |
Seen and left out
These carry comparable signal and have a structural problem as an independent business. Listed so you know what got filtered and on what grounds.
Replacing fax in healthcare
A 117-upvote complaint in r/sysadmin, and the pain is entirely real. It is also a HIPAA-regulated market, and the compliance cost will flatten you before you have a first customer. Suited to a team that already holds healthcare credentials.
AI content detectors
Loudly wanted, and not reliably buildable. False positives damage exactly the human creators you would be selling to, which is why item ten is inverted into proving authorship instead of detecting machines.
A ghosting-employer database
Two threads in r/jobsearch with 208 and 119 comments are pushing for this, and the feeling behind it is strong. But it is user-generated content plus defamation exposure plus nobody to bill. That is a public service, not a business.
Generic file conversion
Mentioned constantly — googling jpg to png again — and thoroughly commoditised, a bloodbath in search, with no retention from a single use. There is no pricing power to be had.
The limits of this document
Three constraints and two assumptions that could invalidate the whole thing.
Competitor research here is shallow
For each item I confirmed that the named competitors — Jobber, AppFolio, Greenhouse and the rest — exist and cover the territory. I did not trial them, read their pricing pages, or go through their negative reviews. Judgements like “expensive and heavy” are relayed from Reddit, not verified by me.
The price points are guesses
Every figure in the table is inferred from what comparable products charge. Not one has been tested against a real buyer. Treat them as a starting point, not a conclusion.
No supply side was checked
Item six assumes law firms will pay $99–299 a seat for an admin tool, and I have not spoken to a single lawyer. Every willingness-to-pay score is inferred from the intensity of complaint, and there is a canyon between complaining and paying.
Where I could be wrong
Assumption 01
Intensity of complaint stands in for willingness to pay
The entire ordering rests on this. But the loudest complainers are frequently the ones with no budget, and item eight is the illustration: demand scored 5, willingness to pay scored 2. To overturn it you would only need three historical cases where a loudly-demanded product shipped and nobody bought it.
Assumption 02
The pain at the handoffs is not already covered
Pattern 01 is the foundation of the whole document. It could equally be that these people are using the wrong tools, or that their companies are not yet big enough to justify the right ones. To test it: take the target user for item one and ask have you tried Jobber, and why did you stop — not do you have this problem.
