Hey Product Hunt! 👋 I'm a 17-year-old student from Kolkata, building this entirely from my phone — no laptop, no funding, just free-tier tools and a lot of trial and error. Spark Founder AI is my attempt at solving something I felt myself as a first-time founder: no one around to challenge my assumptions before I spent months building the wrong thing. So I built an AI co-founder that pushes back honestly instead of just validating whatever I say. What's inside: 🧠 AI Chat — brainstorm and get real pushback on your idea, not just encouragement 🔥 Startup Roaster — brutally honest feedback before you build, so you hear the hard truths early 💡 Business Idea Generator — explore validated directions if you're starting from scratch 🗺️ Roadmap Builder — turns a vague idea into concrete next steps you can start this week 📊 Pitch Deck Generator — generates an investor-style deck, now with editable assumptions and sourced market claims (a fix based directly on user feedback — my early version was too confident about numbers it couldn't back up) ✅ Idea Validator — scores your idea across key categories to show where it's strong and where it's weak Building solo as a student has meant a lot of debugging on a phone screen, a lot of "why did this revert" moments, and learning way more about security and deployment than I expected to this early. But it's also meant I get to ship fast and actually listen when users tell me something's not working. Would love your honest feedback — especially anything that feels off, confusing, or unnecessary. That kind of pushback is exactly what makes this better.
