About us

About Us

🧭 We are a small crew of finance nerds and designers who got tired of spreadsheets that hide the one number that matters: how long you can last.

🎯 Our mission is to make financial runway visible, calm and private, so freelancers and founders can plan boldly without handing over their data.

📈 RunwayGrid gives you burn rate maps, shock simulations, subscription drain views and freedom targets, all running instantly on your own device.

🛡️ It matters because clarity lowers stress, and trust is easier when nothing ever leaves your phone. Know your months. Keep your secrets.
