Why Jeff Klimkowski's Goal is Zero Free Cash Flow Growth and How Diesel Dan AI Agent Helps

Jeff Klimkowski didn’t plan on his career ending up in the toilet (pun intended.)He was a Deutsche Bank investment banker. The kind of kid who made his sister drive him to school so he could read the Wall Street Journal in the passenger seat. He had the job. The trajectory. The spreadsheet-perfect life plan.Then his childhood friends had too many burritos and a dumb idea.Flushable wipes for men. They called it DUDE Wipes.Jeff left banking to become CFO, co-founder, and—for a while—the company’s personal line of credit. His i-banking bonuses funded the working capital. His cash and DUDE’s cash were the same thing.That detail matters more than anything else in this conversation.When your money and the company’s money are the same pile, you think differently about every dollar.You can’t be reckless. You can’t be timid. You have to be precise—because the category is moving faster than your spreadsheets and hesitation means someone else defines the future.After Shark Tank, Jeff and co-founder Sean Riley pitched 20 to 30 VCs. Every single one said no. The biggest rejection? “You’ll never get guys to use wipes.”So they got profitable.Q4 2016. First profitable quarter. They haven’t looked back since. No outside capital beyond Mark Cuban’s original Shark Tank check until they hit escape velocity.DUDE Wipes crossed $300M in annual retail revenue. They’re growing roughly 50% per year. And Jeff has never been more bullish in the company’s history.Jeff didn’t just become CFO. He redesigned what the role means.At DUDE Wipes, four verticals roll up to the CFO: Finance and accountingFP&ASales strategySupply chain. The problem with how the industry defines the job is that most people think it’s just the first one.Jeff sits in every major Walmart and Target line review alongside Sean. He hears from the buyer’s mouth what their long-term strategy is—so his forecasts aren’t built on salespeople’s optimism alone. He goes to co-manufacturer meetings so he can look at the whites of the buyer’s eyes before he commits working capital to inventory.This is not how most CFOs operate.Most CFOs sit in a skybox. Jeff is on the field.And here’s his financial philosophy in one sentence: “EBITDA is the most overrated metric on the face of the planet.”Zero free cash flow. That’s the goal.Not because DUDE Wipes isn’t profitable. Because every dollar of EBITDA gets reinvested—into working capital, CapEx, and marketing—until free cash flow hits zero at year’s end.Zero means Jeff is deploying capital at the exact speed the category demands.Too much free cash flow? You’re not investing enough. You lack conviction. The category will outgrow you while you sit on cash.Negative free cash flow? You’re over your skis. You’ll need to raise money, dilute equity, and lose control.Zero is the surfer sitting in the pocket of the wave.Jeff knows the max growth rate they can sustain in a given year because of this discipline. Right now: 50% per annum at zero free cash flow. When numbers get big, 50% is a big number.And it’s not set-it-and-forget-it. They’re tweaking the plan constantly—rolling 12 months on the finance side, rolling 24 months on supply chain. New data in, new adjustments out.The make-free-cash-flow button.Eddie asked Jeff: when you need to push the free cash flow number, what do you press?The first answer was boring and brilliant: cash collections from retailers.Nobody was quarterbacking receivables. Invoices were getting lost in EDI transmissions. POs weren’t registering correctly between systems. Charge-backs went uncontested. It’s the kind of work nobody glamorizes—but hiring one person to own it improved cash collection by 40%.Now they’re layering in AI agents to match invoices, flag errors, and automate the back-and-forth with retailer portals. The person quarterbacks. The agents do the grunt work.Second answer: SKU-level demand planning. DUDE Wipes knows how much they’ll sell. The problem is the mix—selling the right product at the right time to the right channel. When a new innovation outperforms expectations, there’s a 90–120 day lead time before they can adjust production. AI that ingests retailer data and optimizes assortment by channel compresses that gap.Real example: DUDE Wipes was running promotions at food retailers and only seeing 10–15% lift versus competitors. Why? They were selling out by Wednesday. Empty shelves for the rest of the week. High-growth category problems that only show up when you look at the data with precision.Meet Diesel Dan.Greg Brown, DUDE Wipes’ SVP of Ops and Technology, built an AI agent called Diesel Dan.Here’s what Diesel Dan does: when the manufacturer finishes a production run, an automated report gets sent over. Diesel Dan reads the report, books trucks across three counterparties, maximizes weight and volume per load, and notifies the operations team. Fully automated.Before Diesel Dan, inventory piled up at the manufacturer because trucks weren’t getting booked fast enough. That meant less production capacity. That meant slower growth. That meant working capital sitting in the wrong place at the wrong time.Dan fixed the bottleneck. Stockouts dropped. Freight costs stabilized. And the operations floor went from reactive to predictive.As Jeff put it: “Dan never sleeps, never guesses, and never forgets.”This episode isn’t about spreadsheets.Or accounting.Or even AI.It’s about what happens when the CFO stops being the department of no and starts designing the financial system that powers category creation.Jeff’s approach works because the conditions force it. Skin in the game. A new category that didn’t exist. And a bootstrap discipline that makes every dollar earn its spot—or get cut.That’s the Agentic CFO.Here’s how to navigate this conversation:00:00 – From Deutsche Bank to DUDE Wipes: Jeff’s origin story—the Wall Street Journal in the passenger seat, the dream job, and the childhood friends who derailed everything.01:59 – The four verticals of a real CFO: Finance & accounting, FP&A, sales strategy, and supply chain.
