Seven SaaS ideas worth building before they go mainstream

Executive overview

Most SaaS ideas are hiding in plain sight — feature request boards, Reddit threads, and niche forums where users beg for solutions that don't exist yet. Rob Walling walks through seven concrete opportunities, sourced from public demand signals, that fit the "step one business" profile: small scope, real pain, existing audience.

Validated market demand, not inspiration, is the most reliable starting point for a SaaS idea.

Ideas sourced from platform gaps

• Client portal for Wix — freelancers and agencies want file sharing, project requests, invoicing, and individual client logins; no good native or plugin solution exists.
• Support ticket system for ClickUp — a five-year-old feature request with 2,500 upvotes; ClickUp's workaround leaves users unsatisfied; high platform risk but strong pull.
• Architecture plans review and commenting tool — described as "Frame.io for architectural drawings"; incumbent Bluebeam starts at $240/seat, leaving room for a focused, cheaper alternative.
• In-person event venue setup planner — drag-and-drop stage and equipment layout tool; saves venue staff time on miscommunication with rental customers; customer profiles for repeat renters.

Ideas from the no-code ecosystem

• Version control for no-code apps — view history, set versions, branch, rollback, webhooks; requested as embeddable UI plugins for existing platforms.
• Automated testing for no-code/low-code — equivalent of unit and integration tests; no platform has solved this; open to indie developers building a plugin.

Idea: low-setup product analytics

• Install a JS snippet; tracks all page visits and actions automatically.
• Tell it the target conversion event (e.g. subscription thank-you page).
• Returns the common paths taken by users who converted — no consultant required.

Bonus idea: HTML-to-email screenshot API

• Post a payload of HTML, a device type, and a target email client.
• API returns a screenshot of that HTML rendered as an email on that device in that app.
• Similar to Litmus but API-first; suited to developers building email tooling.

How to find your own ideas

• Browse feature request boards for major SaaS platforms (listed at microconf.com/marketplaces).
• Look for requests with high upvotes and old timestamps — unmet demand over time signals a real gap.
• Check Reddit threads in professional niches where users describe workarounds or ask for tool recommendations.
