Small problems pay better than big ideas
Software as a Service keeps creating opportunities for people who want a business built on recurring monthly revenue. But you don't need to invent the next Salesforce, Shopify or Slack.
Some of the most practical opportunities come from solving small, expensive, repetitive problems for specific businesses. A simple product that saves an owner several hours every week can be worth more than a complicated platform with hundreds of features.
Customer communication and lead capture
These ideas sit closest to the money, because every missed call or slow follow-up is a lost sale. An AI receptionist alone fits dentists, clinics, law firms, real estate agencies, home-service companies and consultants.
- AI receptionist that answers calls, replies to common questions, captures leads and books appointments
- Lead follow-up automation across email and SMS
- Review management platform for requesting reviews and monitoring reputation
- Appointment scheduling with reminders, cancellations and rescheduling
- Customer support AI that answers questions from a company's own documentation
- AI lead qualification that questions prospects and passes qualified leads to sales
- WhatsApp business automation for companies handling large message volumes
- AI email assistant that drafts personalised sales follow-ups

How to choose the right idea
The best idea isn't the most complicated one. Look for a problem that is frequent, expensive, repetitive, time-consuming, solved manually today, and important enough that businesses will pay to fix it.
A useful question: what task does this business perform every week that it would happily stop doing? That leads to better ideas than chasing trendy technology.
- Start with a specific customer: not "businesses" but "US HVAC companies with 5–20 employees"
- Start small — a first version can solve one important problem extremely well
- Choose something that delivers value again every month, so a subscription makes sense
- Build around the business problem; technology is only the tool
Key Takeaways
- Solve one painful weekly task for one type of business.
- A specific customer makes the product and the marketing easier.
- Recurring value is what justifies a monthly subscription.
