💡 Pro Tips for chatgpt agent builder Startups

  • Start with one user segment. Don't try to serve everyone. Pick the segment with the most pain and highest willingness to pay.
  • Ship fast, iterate faster. Your first version will be wrong. Get it in front of users within 4-6 weeks and learn from real feedback.
  • Charge from day one. Free users don't give useful feedback. Start at $29/month and adjust based on value delivered.
  • Build in public. Share your journey on X/Twitter. The chatgpt agent builder community will help you find your first customers.
  • Focus on one acquisition channel. Master SEO, content, or community before expanding. Spreading thin kills startups.
