Why I built this

15 years as a CFO before I became a founder myself.

The thing that kept killing companies I worked with wasn't high burn. It was that founders didn't know their exact runout date. Ask them their burn rate — they had a rough number. Ask them the exact month they'd hit zero — silence.

By the time they knew, it was usually 6 weeks away.

I built this in a weekend. No login, no upsell. Just the number every founder should know.

Would love brutal feedback on what's missing.
