100 Market-Hole Patterns
Templates that produce product ideas which should work, at least by logic. Take one pattern, plug in a market, and you get an idea.
What the leader structurally can't do (1–25)#
- A self-hosted version of a SaaS tool. The leader depends on hosting revenue. Example: beehiiv inside WordPress.
- A hosted version of a self-hosted tool. Some users want the tool but not the server.
- No revenue cut where the leader takes a percentage. Substack takes 10% and can't drop it.
- A one-time price where the leader only sells subscriptions. A company judged on recurring revenue can't do this.
- Public pricing where the leader says "contact sales."
- A cheaper version after the leader moves upmarket. A leader's minimum price keeps rising over time.
- A premium version (support, SLA, compliance) of a tool built for individuals.
- Privacy-first where the leader makes money from data. Example: Plausible vs. Google Analytics.
- An EU-hosted version of a US tool.
- No lock-in and full export, where lock-in is the leader's moat.
- An open-source version of a closed tool. Sell the hosting and support.
- A simple version of a complex tool. The leader can't remove features its big customers use.
- An opinionated version of a flexible tool. Example: Ghost vs. WordPress.
- A version of a general tool for one industry. "Newsletter for local news."
- Local language and local payment methods where the leader is English-only and Stripe-only.
- A neutral tool where the leader competes with its own users.
- "You own your audience" where the leader owns the network (the Substack app).
- No algorithm and no ads where the leader lives on ads.
- Human-made or verified where the leader goes all-AI.
- Built around AI from day one where the leader adds AI onto an old UI.
- Works offline / on your own machine where the leader is cloud-only.
- Users left behind when a product shuts down. Example: Google Reader → Feedly.
- Users neglected after an acquisition.
- Users priced out by a price hike.
- Legal niches a leader refuses by policy (high-risk payments, regulated industries).
Assembly = product (26–38)#
- Stack in a box. The 5 tools one audience uses, combined into one product.
- Glue between two tools that don't talk to each other.
- The workflow between tools, wherever people copy-paste today.
- Business in a box for one industry. A local news site = theme + paywall + newsletter + ads + events.
- Templates and kits on top of a popular tool.
- Done-for-you setup of a complex tool.
- Managed hosting of an open-source tool for one niche.
- The full journey for one role. Write → grow → earn → measure.
- One dashboard for data spread across 5 tools (Stripe + ads + subscriptions).
- A migration tool between two platforms (Substack → WP).
- An onboarding layer. The tool is fine; the first 30 days are hard.
- A compliance pack for one niche (GDPR, accessibility, cookies).
- A starter kit for a new platform.
Transpose: same idea, different audience (39–60)#
- Product X for platform Y. Shopify app → WP plugin, WP plugin → Ghost/Framer.
- Country A → country B.
- Industry A → industry B.
- Enterprise → small business. Example: Salesforce → Pipedrive.
- Pro → beginner. Example: Photoshop → Canva.
- Beginner → pro, for users who outgrew the easy tool.
- B2C → B2B, or B2B → prosumers.
- Desktop → web → mobile → inside chat (a Claude or ChatGPT app, an MCP server).
- Agency service → software.
- Software → service, for people who won't do it themselves.
- A manual offline service → online.
- Spreadsheet → app. Every popular spreadsheet template is an app idea.
- A GitHub script → a hosted product for non-coders.
- API → UI, or UI → API.
- Command-line tool → GUI.
- Popular tutorial → one-click tool. If 50k people a month read "how to X," sell X.
- Popular Fiverr gig → a productized tool.
- Popular Zapier zap → a dedicated app.
- A question that keeps coming up in forums → a tool.
- An idea that failed 10 years ago, retried now that the timing has changed.
- Old idea + AI, done at a tenth of the old cost.
- A habit moving to a new medium (radio → podcast → newsletter → ?).
Slice, unbundle, build around (61–70)#
- Unbundle one feature and make it the best version.
- Unbundle by persona. The same tool, only for editors.
- The most-requested feature the leader has ignored for years. Check their public roadmap and forums.
- Add-ons for a big product (the WooCommerce extensions pattern).
- The ecosystem around a hit product. Themes, integrations, training, hosting.
- Tools that go with a new hit (for Claude Code users, for Substack writers).
- A tool for a rare or yearly event (an election coverage kit for news sites).
- The last mile. The tool does 80%, and customers struggle with the last 20%.
- The back office for a customer-facing tool (billing, reports, team management).
- A quality layer. Checkers, validators, audits.
Timing holes (71–80)#
- A new regulation → a compliance tool (the EU Accessibility Act).
- A platform shutdown or API change → a replacement.
- A price hike → a cheaper alternative.
- A new marketplace opens → be in the first 100 listings.
- A new API is released → be the first app that uses it.
- A cost collapse (AI translation) makes features that were too expensive possible.
- An algorithm shock (a Google update hits publishers) → tools that shift traffic to email.
- Recurring calendar events (elections, sports seasons, Black Friday).
- A trend wave → sell picks and shovels, don't mine the gold.
- A shift in how people live or work (remote work, aging, the creator economy).
Customer-signal holes (81–88)#
- The top 1-star complaint about a competitor → a product that fixes only that.
- Search volume for "X alternative" → build the alternative.
- Whatever people hire a virtual assistant for → automate it.
- Your own repetitive task → productize it.
- A tool you built for your own business → sell it (Basecamp, Slack).
- Your most repeated support tickets → a product.
- Wherever your customers spend their next dollar.
- A job people hack together with 3 plugins → one plugin.
Business-model holes (89–95)#
- The same product with a different pricing model (usage-based, per site).
- A paid pro layer or paid support for a popular free open-source tool.
- A curated directory where the information is scattered.
- A data product built from public data nobody has organized.
- A marketplace where only directories exist today.
- A guarantee layer. "Done, or your money back."
- Education, community or certification around a popular tool.
AI-era holes (96–100)#
- An AI agent that does one role's job end to end (for a 3-person newsroom).
- An MCP server or plugin for a popular tool that doesn't have one.
- Making things readable to AI (GEO and llms.txt for WordPress sites).
- A trust layer where AI content floods in (provenance, fact-checking).
- A service with AI inside, sold at software margins.
Best fit for the newsletter-in-WordPress plan: #1, #3, #17, #29, #35. Each one is a gap Substack or beehiiv can't close because of how their business works.
