Twenty curated niches, ranked by willingness to pay.

r/HVAC and r/TradeJobs threads asking "is there software for my 3-truck crew that isnt ServiceTitan" hit the front page weekly, with a steady stream of "I built a spreadsheet" follow-ups. Ahrefs CPC for "hvac dispatch software" sits at $32+ and the cheapest competitor floor is $149/mo per truck, so the willingness-to-pay baseline is already validated.

Local "dental office manager" subreddits and the Front Office Rocks community fill with recurring threads on phone-handling chaos and the no-show tax. Ahrefs CPC on "dental patient recall software" clears $24, and the incumbent per-chair pricing already sits above $300/mo, signalling an anchored ceiling buyers will pay without complaint.

r/Etsy and r/EtsySellers run weekly "how do you track COGS for taxes" megathreads with hundreds of replies from sellers doing it in Notion or spreadsheets. Ahrefs CPC on "etsy profit tracker" is in the $9–$14 band and the closest paid tool still asks $19/mo for a problem most buyers only feel once a year at filing time.

r/LawFirm and solo-practice forums are saturated with intake-call horror stories and "Clio is too much for me" sentiment from 1–3 attorney shops. Ahrefs CPC on "law firm intake software" sits above $40 and the floor of the lightweight alternatives is already $99/mo, well below what an intake call is worth to a solo PI or family-law practice.

r/gamedev and r/IndieGaming threads asking about royalty splits, contractor invoicing, and storefront reconciliation are constant; "still using a spreadsheet at tax time" is the recurring punchline. Ahrefs CPC on "indie game royalty tracker" is modest ($3–$7) but the closest paid tool still floors at $49/mo, and studios of 2–8 people are visibly willing to pay that to stop the spreadsheet tax headache.

r/WeddingPhotography and r/fujifilmsimulations run weekly "how do you track leads vs. shoots vs. albums" threads, with most pros admitting they lose leads in DMs. Ahrefs CPC on "wedding photography CRM" is in the $6–$11 band and the cheapest competitor floor is $29/mo, which is below what a single mid-tier wedding booking converts into.

r/Accounting and fractional-CFO communities pick apart the monthly reporting loop every week, with the same "Xero + Google Sheets + prayers" complaint. Ahrefs CPC on "monthly financial reporting" for SMB operators clears $18, and the cheapest SaaS floor for fractional-finance tooling is already $149/mo.

r/GoRVing and r/boating owner-side threads surface weekly "I list on three platforms, none of them talk to my calendar" complaints, with the smaller operators asking for a single-pane listing tool. Ahrefs CPC on "rv rental software" sits at $11–$19 and the closest host-stroud platform already takes 8% per booking, signalling that operators will pay to consolidate.

r/tutoring and r/Teachers fill with recurring "where do you invoice recurring students" threads, with most tutors running Calendly plus Wave and complaining about the seam. Ahrefs CPC on "tutor scheduling software" is in the $7–$14 band and the floor of the closest paid tool is $19/mo, comfortably below the hourly rate buyers already charge.

r/RealEstate and r/Landlord threads are saturated with "I have 4–12 units and TurboTenant charges me per door for no reason" complaints — the under-20-unit operator is the under-served middle. Ahrefs CPC on "small landlord software" is in the $10–$22 band and the per-door incumbent floor is already $12/mo, evidence this buyer will pay once a tool just works.
