Indiegogo's co-founder explains that the concept of "runway" doesn't apply to a bootstrapped startup living on savings. Instead of a dwindling cash reserve, the limit is the founders' personal willingness to continue investing their own time and money.

Raising too much money at a high valuation puts a "bogey on your back." It forces a "shoot the moon" strategy, which can decrease capital efficiency, make future fundraising harder, and limit potential exit opportunities by making the company too expensive for acquirers.

A company's runway is not just financial. The failed startup Social Shield had cash in the bank but shut down because the team exhausted all ideas and lost conviction that the problem was solvable, ultimately deciding to return the remaining capital.

The burn multiple, a classic SaaS efficiency metric, is losing its reliability. Its underlying assumptions (stable margins, low churn, no CapEx) don't hold for today's fast-growing AI companies, which have variable token costs and massive capital expenditures, potentially hiding major business risks.

Founder failure is often attributed to running out of money, but the real issue is a lack of financial awareness. They don't track cash flow closely enough to see the impending crisis. Financial discipline is as critical as product, team, and market, a lesson learned from WeWork's high-profile collapse despite raising billions.

A frequent conflict arises between cautious VCs who advise raising excess capital and optimistic founders who underestimate their needs. This misalignment often leads to companies running out of money, a preventable failure mode that veteran VCs have seen repeat for decades, especially when capital is tight.

A profitable P&L can mask imminent death. A big contract booked as revenue makes you feel rich on paper, while you're actually one payroll cycle from insolvency. The only true survival metric is a rolling 13-week cash flow document, updated weekly, showing actual cash in and cash out.

When SpeedSize had less than two months of runway, the co-founders immediately stopped their own salaries. This created a personal sense of urgency, forcing them to solve the cash problem before it impacted the entire team, whose salaries were still months from being at risk.

Many founders believe growing top-line revenue will solve their bottom-line profit issues. However, if the underlying business model is unprofitable, scaling revenue simply scales the losses. The focus should be on fixing profitability at the current size before pursuing growth.
