Runway
Runway is the number of months a startup can keep operating before it runs out of cash, calculated from its current cash balance divided by its monthly net burn.
The clock every founder watches
Runway answers a brutally simple question: how long until the money runs out? Divide the cash in the bank by the monthly net burn rate, and you get the number of months left before zero. A company with ₹24 crore in the bank burning ₹2 crore a month has a twelve-month runway.
For Indian startups this is no longer a back-office metric. After the funding slowdown that stretched the gap between Series A and Series B, investors now expect founders to plan for far longer runways than the eighteen-month norm of the 2020-22 boom. Many institutional backers want enough cash to last well beyond the next round, because that round may take far longer to arrive.
Reading runway in the wild
Public disclosures make the concept concrete. Reporting on FY25 numbers, analysts pegged Ola Electric's runway at roughly eighteen months, with a monthly cash outflow near ₹200 crore against cash reserves of about ₹3,518 crore. Swiggy, with around ₹4,623 crore in cash and liquid investments, was estimated to have close to twenty-six months. The arithmetic is the same for a two-person seed startup and a listed giant.
Through the recent downturn, a majority of startups reported their runway shrinking year on year, prompting bridge rounds, hiring freezes and aggressive burn cuts. Indian founders trimmed burn sharply on average, partly because high-burn companies were being handed steep valuation discounts versus peers with healthier runways.
Why it shapes strategy
Runway is really a measure of bargaining power. A founder with eighteen months of cash can wait for the right valuation; one with three months is a forced seller. That is why "extending runway" — through cost discipline, slower hiring, or a bridge round from existing investors — dominates boardroom conversation in a tight market.
The metric also disciplines growth. Burning fast to chase scale only makes sense if the next funding milestone is realistically within reach before the runway ends. When capital is scarce, the safest strategy is often to lengthen the runway and reach profitability — or at least a credible path to it — before the cash, and the clock, finally run out.
