Bridge & extension.
Runway paths and bridge terms, modelled before you ask.
When the next round looks harder than the last, model each path to default-alive before you ask existing investors for more, and pick the one the numbers support.
“If we cut burn 20% and take a $1.2M insider SAFE, do we reach default-alive?”
At the 5th percentile, cash gets tight in month 14.

When the next round is harder than the last
The next round is harder
The milestones that raised your last round may not raise the next one, and the runway can run out first.
You can't see the cliff
Without a clear runway map, you don't know how many months of room you really have.
Bridge terms are a black box
SAFEs, convertible notes and insider rounds convert at different prices, and their combined dilution is easy to underestimate.

Switch between cutting burn and raising a bridge to see runway and the default-alive month change.

The talk with your existing investors
Three runway scenarios and a recommendation, ready before the investor call.
You're asking the people who already backed you for more, and they will want the downside as well as the plan. You walk in with three runway scenarios and a recommendation, and you can show why you chose the path you're asking them to fund.

- Each bridge option's dilution, shown fully diluted
- A recommendation tied to the numbers

Questions about bridges and extensions
What does 'default-alive' mean?
It means that on your current growth and spending, revenue covers costs before the cash runs out, so the company survives without raising again.
Can it model insider and SAFE bridges?
It's built to. Each bridge option shows its dilution, fully diluted, before you sign.
How do I present this to existing investors?
You bring a small set of scenarios and a recommendation, each tied to the numbers behind it, including the downside case.
