ExitSignal - Calculate your SaaS valuation in seconds

Hi Product Hunt! 👋 I'm Takumi, a student from Japan 🇯🇵. Valuations are often too complex for indie hackers. So, I built ExitSignal in just 24 hours! ⚡️ It helps you calculate your SaaS value instantly based on MRR, growth, and churn. ✨ Features: Simple & fast valuation logic Built with Python/Streamlit Find your “exit price” Note: Currently, the app texts are in Japanese only. I'm studying English to build a global company. I'd appreciate your feedback! 🚀
