Building my first fully vibe coded SaaS for the Polar x Lovable hackathon

I've been writing code for 10+ years. This is the first product I'm building without writing code myself.

The hackathon: $10k to whoever makes the most revenue in a month. Nobody has revenue yet so it's still early.

I'm building Saveyond, a profit-first finance tool for founders. The idea came from my own experience. I've been sharing MRR updates for months but kept thinking "what's my actual profit?". I had no answer.

You know your MRR. You don't know your profit. That's what Saveyond fixes.

Building with Lovable + Supabase + Polar. Will share updates as it comes together.

Anyone else in the hackathon?
