Why Unmanaged Growth Can Devour Startup Cash, According to Cruz Gamboa

In a recent LinkedIn post, Cruz Gamboa discusses a critical, often overlooked, challenge for growing businesses: cash flow. Many founders believe that increasing revenue is the ultimate solution to financial difficulties, but Gamboa argues that unchecked growth can, in fact, be the very factor that leads to their downfall.

Gamboa highlights the deceptive nature of rapid expansion when cash management is not prioritized. He points out a common misconception among entrepreneurs:

“Most founders think growth will fix their cash problems. Growth is what breaks them.”

The core of Gamboa’s argument lies in the arithmetic of cash flow, particularly concerning the time it takes for a company to collect payments from its customers. He illustrates this with a clear example:

“A company doing $100K/month with a 60-day collection cycle has $200K floating out there, permanently. Double the revenue? $400K floating. Same cycle. 4x the hole.”

This stark illustration, as Gamboa emphasizes, is not a theoretical exercise but a practical reality governed by basic mathematics. He refers to this phenomenon as the “Cash Void,” a situation where the company’s expenses are paid before customer payments are received, leading to a significant gap in available funds.

The Arithmetic of the Cash Void

According to Cruz Gamboa, the issue stems from the interplay between accounts receivable, inventory, and accounts payable. While revenue figures on an income statement might look impressive, the actual cash in the bank can dwindle if the collection cycle remains long. Gamboa explains that this isn’t just a minor inconvenience; it’s a fundamental reason why even seemingly successful, seven-figure businesses can face insolvency.

He elaborates on the mathematical components involved, mentioning:

“The full math — DSO + DIO − DPO, the Cash Void, the Capital Bridge — is in this week’s Ascend & Scale.”

Here, DSO (Days Sales Outstanding) represents how long it takes to collect payments, DIO (Days Inventory Outstanding) relates to how long inventory sits before being sold, and DPO (Days Payable Outstanding) refers to how long the company takes to pay its own suppliers. A significant gap between when a company pays its bills and when it gets paid by its customers creates the “Cash Void.” Gamboa’s “Capital Bridge” likely refers to the financing needed to cover this gap.

The Founder’s Dilemma

Gamboa’s insights serve as a crucial reminder for founders that sustainable growth requires more than just increasing sales. It demands a deep understanding and active management of cash flow dynamics. Without sufficient working capital to bridge the gap created by long collection cycles, even a company with a strong product and growing customer base can find itself in a precarious financial position.

The key takeaway from Gamboa’s post is that founders must proactively address their cash conversion cycle. This might involve strategies to shorten collection times, optimize inventory management, or negotiate better payment terms with suppliers. Ignoring these operational aspects in the pursuit of top-line growth, as Cruz Gamboa warns, can lead to a “hole” that ultimately proves too large to escape.
