Me and my co-founder are building vibe coding platform for mobile apps. Where you can build mobile apps with supabase as backend along with AI capabilities or just UI depending on your requirement. It all started with Paul Graham's advice.
We launched FlexApp publicly on March 15th after our first demo went viral with 200 users on waitlist.
We were on the right path: a niche tool to only build mobile apps.
Soon hitting 50 new signups daily. All these signups came with massive LLM costs. Starting with just ~$4K, we burned through 30% of our budget in the first week with only $260 MRR.
