What it is

Earnings call digest for retail investors is an AI-agent business for retail investors and investment clubs. Concretely: plain-language summaries of earnings calls and reports for watchlist stocks, with changes in guidance and key risks.

Who pays & why

Who pays: retail investors and investment clubs. Why: the agent does, quickly and around the clock, work they would otherwise do by hand or pay a person for. Recommended price: €12/month. You know it is working when you see: subscribers, digest open rate. Main risk to manage: investment advice regulation, summary errors.

How it works

  1. Customers find you through: X/Twitter finance community, Reddit, newsletters. They sign up on your website.
  2. The agent collects its inputs automatically using: Web scraping.
  3. AI does the core work with: LLM API.
  4. Automatic quality checks run before delivery; anything unusual is sent to you for review.
  5. The result is delivered through: Email / newsletter.
  6. Payment is collected automatically (€12/month).
  7. Every week you check: subscribers, digest open rate.

Concrete example

Example: a customer from the target group (retail investors and investment clubs) signs up. What they get from the first week: plain-language summaries of earnings calls and reports for watchlist stocks, with changes in guidance and key risks. The customer pays €12/month. On your side you spend about 3 h per week on: reviews a sample of AI outputs and corrects the prompts when quality drifts; validates the editorial line and approves sensitive content.

📊 Key metrics

Revenue potential: High (est. €2000–6000/month)Running costs (tools & APIs): €45–595/monthAutomation difficulty: 3/5 ModerateHuman time: 3 h/weekIntegration Requirements: 6Setup time: ~56 h (≈6 weeks part-time)Estimated payback (return on investment): ~3 months
How we estimate this

Start-up cost = idea price (€39) + one month of running costs while you build (€320). Monthly profit = low end of the revenue estimate (€2000) 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.
  • Harder to automate (needs set-up and monitoring): Web scraping.
  • Still needs a human: reviews a sample of AI outputs and corrects the prompts when quality drifts; validates the editorial line and approves sensitive content — about 3 h per week.
Automation scale (1–5)
  1. 1 – Very easy: no-code tools, a few hours to set up.
  2. 2 – Easy: standard tools, a few days, little monitoring.
  3. 3 – Moderate: several integrations, 1–3 weeks, regular checks.
  4. 4 – Hard: complex data or sensitive output, a coding agent or developer recommended.
  5. 5 – Very hard: advanced engineering, strict quality and compliance control.
