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.
Most founders know their burn rate. Almost none know their exact runout date.
After 15 years as a CFO I watched that gap kill companies. Not high burn — the lack of precision. "Burning around €20k/month" isn't a number you can make decisions with. "You run out in November" is.
Months Left takes your bank balance, MRR, burn rate, growth rate, and churn — and gives you the exact month, a 36-month cash projection, and a scenario slider showing what a new hire does to your runway.
