Not just cash ÷ burn. Model hiring plans, revenue growth, and 3 scenarios to know your real runway and your exact fundraising deadline.
Step 1 of 3
How much money do you have and how much is coming in?
Actual cash in your bank account right now. Not projected revenue, real money you can spend today.
Cash actually received this month, not invoiced. Pre-revenue? Enter 0.
We calculate your real monthly cash loss: total expenses minus cash revenue. Most tools use gross burn, which makes runway look worse than it is. Net burn is what actually matters.
We factor in planned hires (which raise your burn), revenue growth (which lowers it), and amortize one-time costs so spikes don't distort your true average burn.
A round takes 3-6 months to close. We subtract that buffer from your zero-cash date to give you the date you must START raising, not the date you run out.
Most founders burn 3-5 months of runway just getting their MVP built. Witsberry delivers a production-ready, investor-ready product in weeks, so you spend less cash getting to traction and stretch your runway further. 50+ products shipped. We tell founders what NOT to build.
