📊 Key metrics

Revenue potential: Medium (est. €800–2500/month)Running costs (tools & APIs): €25–545/monthAutomation difficulty: 3/5 ModerateHuman time: 2 h/weekIntegration Requirements: 6Setup time: ~56 h (≈6 weeks part-time)Estimated payback (return on investment): ~5 months

How we estimate this

Start-up cost = idea price (€39) + one month of running costs while you build (€285). Monthly profit = low end of the revenue estimate (€800) minus average running costs. We assume 2 months of ramp-up at half revenue and add your setup time. Your own working hours are not counted. It is an estimate, not a promise.

⚙️ Automation difficulty: 3/5 – Moderate

Why this automation score

Score 3: several moving parts (data collection, AI output, delivery) need testing and monitoring.
Easy to automate: Database, Web server / hosting, Payments, LLM API and Email / newsletter.
