CFO

[Di Mike, CFA @DiMikeWang]

The most expensive finance hire is the one you make 18 months too late.

By then messy books cost you a raise, a cash surprise cost you a quarter, and the bad calls can't be unmade.

The bill comes due all at once.

A 40-row report nobody reads is worse than no report. It feels like control without the substance.

Revenue was $1.2M = data.
It dropped 6% on a pricing slip in one segment = insight.

You act on the second one.

Investors don't reject you because your numbers are bad.

They reject you because you can't explain them.

There's always a moment where a 28-year-old asks why margin moved 4 points. Pause, and you're done. Not the margin — the pause.

@PeterLBrandt Wykoff. Could be early signs of risk off, dollar up

A founder asked me last week: hire a $150K salesperson, or put the same into ads? He'd already decided. He just wanted me to bless it.

My one question back: what return do you expect, and by when? He had no number for either.

That's the gap.

[Di Mike, CFA @DiMikeWang]

You're working hardest to grow the part of your business that loses money. You just can't see it yet.

Blended margin hides it. Break it down by customer and a chunk of your revenue is unprofitable — often the accounts you chase hardest.

[Di Mike, CFA @DiMikeWang]

A founder told me he needed to raise to fund growth.

I found him $600K he already had — trapped in receivables and inventory.

Customers pay you in 70 days, you pay suppliers in 30? You're financing the gap. Close it and free real cash.

[Di Mike, CFA @DiMikeWang]

Profit is an opinion. Cash is a fact.

Your P&L can say you made money the same quarter you nearly miss payroll.

The fix isn't more bookkeeping. It's a 13-week forward cash forecast. A windshield, not a rearview mirror.

The Sell Side Indicator cuts the other way — strategists turning cautious is contrarian bullish, fair. But my bear case isn't a bank's note. It's QQQ at its most stretched vs trend in ~27 years, a −4% break that started from VIX 15 with zero capitulation, and the bounce led by the highest-beta names. Price, not a press release.

[Di Mike, CFA @DiMikeWang]

@FrankCappelleri Many more "blue" responses than "red". Another data point for red.

[Di Mike, CFA @DiMikeWang]

QQQ +1.7% the day after Friday's −4%. Everyone's calling the V-bottom.

I think it's a trap, and the tape today says so: classic risk-on snapback — QQQ and IWM (high-beta, high-multiple) leading while DIA lags. The names that fell hardest bouncing hardest, not broadening.

But the real tell is vol. VIX 18.67, −13%, and there was never any capitulation — Friday only took it from 15 to low-20s. Every durable bottom in an extended, late-cycle, richly-valued tape came AFTER a spike into the 30s–60s. We didn't get one. We got complacency bought right back.

Bounce off the FIRST big down day, from a low-VIX top = bull-trap signature. 2000, Q4 '18, Nov '21 all rhymed. The clean V's (Aug '24, Apr '25) all needed a fear spike first.

One green day proves nothing — most −4% days do get bought. But the regime tilts this bearish, and nothing today changed that. Watching whether VIX bleeds back to 15 (dip-buyers win) or sticks high while price rises (distribution).

Your bookkeeper can tell you exactly what happened last month.

They can't tell you if you'll make payroll in March.

That's not a knock. It's the job description. Recording the past and deciding the future are two different jobs.

[Di Mike, CFA @DiMikeWang]

A founder lost ~$900K of valuation in one board meeting.

The lead asked: "Why did cash drop 40% while revenue grew?" He didn't know.

Term sheet came back 15% lower. Diligence dragged 6 extra weeks.

There was no "missing CFO" line on his P&L. It showed up as a worse deal instead.

[Di Mike, CFA @DiMikeWang]

A SaaS founder asked me: "We crossed $8M ARR growing 60%. Why are we burning MORE cash every month?"

CAC $9K→$16K. Gross margin 62%, not the 80% they assumed. New customers cash-negative for 19 months.

Growth wasn't building the business. It was accelerating the burn.

Growth amplifies whatever economics you already have.

[Di Mike, CFA @DiMikeWang]

Magic Number = (Net New ARR × 4) ÷ Prior Quarter S&M Spend

Above 1.0: Efficient growth
0.5-0.75: Concerning
Under 0.5: Broken

Two companies add $300K ARR. One spent $250K (4.8x). One spent $600K (2.0x).

Same growth. Different efficiency.

[Di Mike, CFA @DiMikeWang]

Board prep is not slide preparation.

It is financial infrastructure showing up under pressure.

If the CEO cannot explain why margin moved, why cash is down, or why forecast changed without guessing, the problem is not the deck.

It is the finance function behind it.

[Di Mike, CFA @DiMikeWang]

Most founders ask: how can AI make us more efficient?

Lenders are asking: can AI make this company less defensible?

If you run SaaS, "we use AI" is not enough. You need to show the financial moat: retention, margin impact, churn risk, and workflow lock-in.

Parker raised $200M+.

Then filed Chapter 7. Liquidation.

Funding creates time. It does not create discipline.

A 13-week cash flow model answers the question that matters before every other question:

How much time do we actually have?

[Di Mike, CFA @DiMikeWang]

Renegotiating vendor contracts is not about being cheap.

It is about making sure the price still matches the economics.

Markets change. Usage changes. Alternatives change. Cash needs change.

But contracts usually do not adjust unless someone asks.

That is where companies leave real money on the table.

[Di Mike, CFA @DiMikeWang]

A dashboard nobody uses to make decisions is just expensive decoration.

Every KPI needs three things:

Owner. Threshold. Decision.

If a metric has no owner, no threshold, and no decision attached, it probably does not belong on the dashboard.
