1. Simple CRM for Solo Founders

Pain: "Every CRM is built for enterprise sales teams. I just want to track 50 leads."

Opportunity: A dead-simple CRM with just contacts, notes, and reminders. No pipelines, no forecasting.

Pain: "Calendly is too generic. I need packages, recurring sessions, and payment in one place."

Opportunity: Niche booking tool with training-specific features: session packages, progress tracking, payment plans.

Pain: "I want to know which channels are dead, who my top contributors are, and when engagement peaks."

Opportunity: Simple analytics for Discord server owners. Engagement trends, member activity, dead channel alerts.

Pain: "Every AI-written blog post sounds the same. I need something that captures my voice."

Opportunity: AI writer that learns from your existing content and matches your tone.

Pain: "I bill by project, not hourly. I need partial payments and automatic reminders."

Opportunity: Invoicing tool built for project-based freelancers with milestone billing.

Pain: "I just want a nice waitlist page that tracks signups. Everything is overkill."

Opportunity: One-click waitlist pages with analytics and email notifications.

Pain: "I write everything in Notion. Why can't I just publish it as a website?"

Opportunity: Turn Notion pages into SEO-friendly websites with custom domains.

Pain: "I need one place for clients to see project status, files, and invoices."

Opportunity: White-label client portal that aggregates project info.

Pain: "I want a simple way to share product updates with users."

Opportunity: Embeddable changelog widget with user notifications.

Pain: "I need to schedule user research calls but Calendly doesn't capture enough context."

Opportunity: Booking tool with screening questions and automatic note-taking.
