SaaS Ideas From Reddit: Problems to Investigate
Start with a reported workflow problem, inspect the discussion and compare existing alternatives. A complaint does not establish that the problem is still unsolved or that a new product will sell.

How to investigate these ideas
Read the source in context, look for independent accounts and compare the tools people already use. AI scores help prioritize research; keyword volume describes searches, not buying decisions. Check source dates and whether an existing product or a simpler process already solves the problem. Then test a narrow workflow and a specific paid offer with customers you can reach.
Frequently asked questions
- What is a good SaaS idea in 2026?
- Start with a specific workflow in a customer group you understand and can reach. Investigate the current workaround, compare alternatives and test a small solution. A narrow market or a high AI score does not establish demand.
- How do I find profitable SaaS ideas?
- Investigate problems in a customer group you can reach. Read independent accounts, compare current workarounds and test a specific paid offer. Repeated complaints and keyword volume can guide research; they do not establish profitability.
- How much does it cost to start a SaaS business?
- Estimate the costs of your specific scope, including hosting, external APIs, support and customer acquisition. A generic idea list cannot establish your launch budget.
- What's the difference between SaaS and micro SaaS?
- A micro SaaS is a small software business focused on a specific audience or workflow, often run by a solo founder or a small team. It does not have a fixed revenue ceiling or a required number of features. SaaS is the broader software-as-a-service category.
- Are SaaS businesses still profitable in 2026?
- Profitability depends on the product's revenue, retention, delivery costs and customer acquisition costs. An idea, competitor revenue or search volume cannot establish those economics for a new business. Test them with a specific offer and real customers.
- What SaaS ideas can a single developer build?
- Start with a single workflow and write down the integrations, reliability requirements and ongoing support it needs. An AI feasibility score is not a delivery estimate. Use the micro-SaaS collection to explore ideas selected for solo-founder feasibility, then assess the scope yourself.
