FOR STARTUP FOUNDERS

One Accounting Corp Mistake Erased 7 Months of Startup Runway

Her board slide said 11 months of runway. The bank feed said 4.

Have you ever pulled up your bank balance to answer how much runway is left and felt a cold drop in your stomach because it did not match what you told your board three weeks ago? I watched a Series A-track founder we will call Maren live that in July. This is the story of how her corporation's books stopped telling the truth, and what it cost her.

One founder. Real numbers.

funded startups we reviewed had a runway gap

“I found out my runway was wrong in front of my own board. That never happens again. Amadae closes our books every month, not every quarter, and someone actually tells me what the number means.”

The Story

Twenty minutes into the board meeting, the math stopped adding up

Maren walked in with a slide that said 11 months of runway, the same number that had let everyone relax for a quarter. Her lead investor asked a simple question: is that cash basis or accrual? She did not know. Her bookkeeper had been recording revenue when invoices went out, not when cash landed, and quietly switching methods between quarters depending on what looked cleaner.

The Problem

Startups die from a bank balance nobody double-checked

Founders recognize the pain immediately: books that close weeks late, runway estimated from a bank balance instead of real burn, and a generalist CPA who files once a year and never flags the problem in real time. Every decision gets made on data that is already stale, and most of what gets sold as a fix is the same once-a-year filer with a dashboard bolted on.

What We Tried

A marketplace bookkeeper, a second spreadsheet, and a CPA on watch

Maren had tried the usual fixes: a part-time bookkeeper off a freelance marketplace, a second spreadsheet to cross-check the first, and a CPA asked to keep an eye on things between filings. None of it worked, because none of it was actually watching the books in real time, it just moved the archaeology from April to July.

The Discovery

It was not fraud or negligence. It was structure.

When we pulled the real numbers, the corporation had been set up correctly on paper, but nobody had built the accounting to match how a funded corp needs to run. Revenue recognition was inconsistent. Payroll accruals were not tracked against cap table commitments. If a board deck reports runway straight off the bank balance, a mid-quarter payroll run or one chunky prepaid expense can swing the number by months in either direction; if it reports off an accrual close instead, the same swing shows up gradually as it accrues instead of landing all at once on payday. Her board's burn model used cash basis numbers when investors expect accrual. Same company, two runways, seven months apart.

The FixAMADAE

Books that close continuously, not six weeks after the fact

Amadae is built around accounting for funded startups, which means the books close monthly instead of in arrears, burn and runway update as transactions hit the bank, and a dedicated accountant flags the cash-versus-accrual mismatch that hit Maren before it reaches a board deck. Entity structure, quarterly estimates, and payroll accruals are treated as one connected system, so a change in one shows up everywhere. One flat monthly price, no archaeology, no surprises in a room full of investors.

The Proof

That never happens again

Maren's books now close every month, not every quarter, and the runway number in the board deck is the runway number in the bank. The next time an investor asked cash or accrual, she had the answer and the ledger to back it up.

“I found out my runway was wrong in front of my own board. That never happens again. Amadae closes our books every month, not every quarter, and someone actually tells me what the number means.”

Why NowAMADAE

Fix it before fall fundraising, not in front of the check writers

The next round is when a mismatched runway number gets most expensive to discover, in front of the people deciding whether to write the check. Founders who fix this before fall fundraising spend August closing deals and enjoying the runway they actually have. The review is free, there is no long-term contract, and you leave with a real runway number that holds up under diligence.

Questions creators ask us

We already have an accountant.+

Maren had a CPA too. The problem was never whether she had one; it was that her CPA was hired to file a return, not to catch a mismatch in July before it reached a board slide.

We're too early. We'll fix it when we raise the next round.+

That is exactly backwards. The next round is when a wrong runway number is most expensive to discover, in front of the people deciding whether to invest.

Isn't this more overhead during a busy summer?+

It is the opposite. Founders who fix it now spend the fall closing deals instead of rebuilding trust with a board in September. Plans start at $249 a month, flat.
