Operational Fluency Is How Founders Avoid the Confidence Vacuum

Founders don’t lose board authority over bad numbers; they lose it over uncertainty. Propeller’s Chris Fenster and Charlie O’Donnell of nextNYC on how operational fluency closes the gap before your investors fill it for you.

There’s a moment in almost every board meeting where the financial conversation either builds trust or quietly destroys it. The numbers themselves matter less than how they’re delivered, and what the delivery reveals about the founder’s grasp of their own business.

A “confidence vacuum” opens when a founder can’t articulate the plan. Investors, who are obligated to protect their capital, step in to fill it. If the capital can’t find a credible plan to rally around, the people who deployed it will go looking for one. Recognizing this pattern is what lets you get ahead of it.

Charlie O’Donnell, founder of nextNYC and author of Founder Unfriendly (Wiley, 2026), sees it from the board seat: the founders who maintain authority over the long haul aren’t the ones with the most confident predictions. They’re the ones who know the machine. They can put the right people in front of the board to walk through each moving part: the demand engine, the technical architecture, the revenue model and its assumptions. The outputs might still be uncertain, but command of the inputs is what builds trust.

As Founder and Executive Chairman of Propeller, Chris Fenster has worked with 1,400+ companies over 18 years and watched this moment play out hundreds of times (he’s written about the structural side in “Your Cap Table Is Your Strategy”). The confidence vacuum first surfaced in that cap table conversation, and it turned out to reach well beyond fundraising: into board dynamics, executive hiring, and how founders hold a room. What follows are the six practices they unpacked for building the operational fluency that holds it.

1. Operational fluency is the real definition of confidence

Charlie puts it directly: “Operationally fluent is probably the best and most relevant definition of confidence. Confidence is not ‘I know this thing is going to turn out this way.’ It’s ‘I understand how the thing works. And given I understand how the thing works, and I know what inputs I’m putting in, it feels more predictable than if this thing is just a magic black box and I have no idea how the inputs turn into outputs.'”

Walk into a board meeting with a clear plan, a credible read on the business, and real belief in the path forward, and you’ll hold the room. Even the most opinionated investors tend to defer to a founder who clearly has conviction around the strategy. The legal documents give investors certain rights, but in practice, authority flows to whoever demonstrates they have the wheel.

The flip side is just as predictable. When a founder can’t articulate the path forward, when the plan is fuzzy or the uncertainty is written all over the room, a vacuum opens up. And vacuums get filled: #Physics.

Chris is candid that this one is personal. He’s not wired to fake it till he makes it, so he over-prepares, trusts his instincts, and filters those instincts through people he trusts until the confidence is real. “Finding the right team, putting people around you that get you, that get your wiring, that can help fill in those gaps, is one of the most critical things that a founder can do.”

What to do: Run an honest audit of your operational fluency. Do you understand how your inputs drive your outputs? Can you explain your unit economics, retention drivers, and margin structure without notes? If not, that’s the gap to close. And if you can’t close it alone, hire or partner with someone who can.

2. Accurate lights beat green lights

Most founders walk into board meetings trying to show positive numbers, because green lights mean go. Investors are looking for something different.

As Charlie put it: “A good first impression is not ‘all the lights are green.’ It’s that I have installed this set of lights and they work properly. Some of them might be red, some of them might be green, but whatever it says they’re doing, that actually reflects reality.”

The confidence vacuum forms when investors start to distrust the color of the lights, not when some lights are red. An accurate red light builds more confidence than an aspirational green one.

What to do: Build a reporting system that reflects reality rather than aspiration. If your investors can’t trust the numbers in the dashboard, they can’t trust you.

3. When you take the capital, know what you signed up for

Institutional capital is a package deal. Along with the money, you’re accepting governance (board representation, protective provisions, reporting requirements) and guidance (strategic input, the network, an experienced investor’s perspective). Chris called it the “Faustian Bundle” in their cap table conversation, and when the relationship is working, it’s incredibly valuable. When it isn’t, it starts to look a lot like pressure with better packaging. Investor incentives don’t always align with a founder’s, and the gap rarely surfaces in early conversations.

Add to this the math of fundraising. In Chris’s words: “If you go out to raise $5 million on $20 and you come back with $10 million on $50, your hurdle is literally twice as high. More than twice as high. And so now you’re building a different business than the one you set out to build.”

What to do: Before your next raise, model what the new valuation implies for your exit outcomes. Understand the governance conditions attached to the capital, and know what you’re agreeing to beyond the dollar amount. And get a really good lawyer, one who will explain the terms and the options rather than just hand you a menu.

4. Bad news + no plan = confidence collapse

Transparency is not the same as dumping problems on your board.

Charlie gave a vivid example: “Your cofounding CTO has gotten an offer from Anthropic for $850,000 a year, and he’s leaving. But I have interviewed four awesome candidates to take over, and they’re raring to go … Clearly I didn’t expect you to lose your cofounder. But you didn’t wait for us. You didn’t come into a meeting and just break bad news with no plan on how to address it.”

Investors aren’t rattled by the problem. They’re rattled by a founder who waited, arrived unprepared, and left the vacuum open.

What to do: Adopt a “bad news + response” discipline. Never go in cold, and never with surprises. Before every board meeting, identify the two or three things that could rattle your investors and have a plan for each. Bounce that plan off your inner circle and rehearse it. The plan doesn’t have to be perfect, but it does have to exist.

5. Experienced founders attach to the process, not the idea

From the board seat, Charlie sees a consistent split before product-market fit: “When I see experienced founders before product-market fit, they make very few assumptions about what the business is going to be. They come in and they say, ‘we’re running a set of experiments’ … they feel very open to different information. First-time founders are often totally convinced that this is the business.”

Chris’s framing of why: “The more experienced founders don’t get too attached to the one thing. They get attached to the process. The process to get to product-market fit. And that becomes their ten thousand hours.” Founders who fuse their identity to one version of the business risk ignoring the data points that contradict it. Founders who attach to the process of discovery can show up confident about the experiments themselves, and that confidence in the process is what builds investor conviction, even while the plan is still moving.

What to do: Reframe your board narrative. Instead of defending the original plan, show that you’re running disciplined experiments. Tell investors what signals you’re looking for and at what point you’d change course. That’s the mark of a founder with confidence in the process even when the plan changes.

6. Surround yourself with people who will challenge you

A typical bookkeeper or controller is forensic by nature: they report the past. A strong finance partner pressure-tests the plan, flags the margin problems, and helps you engineer a different future. Chris on what that sounds like in practice: “You just have to get to a point where you’re like, no, I’ve seen this before, and this is not gonna work. Your margins are not high enough to survive the expansion into this next category… or you don’t have nearly enough cash to launch this new product. Sorry to rain on your parade, but this deck isn’t going to fly.” That takes experience and career confidence, and it only works if you empower your leaders to do it.

Charlie’s favorite illustration is Hungryroot. In its early days, the team instrumented everything: constant customer conversations, discrete tests, retention data behind every claim. “By the time that came to a board conversation, it was all anchored in facts and data about consumer behavior … There were times where I would make suggestions, like, ‘I wanna tinker with my mix in the grocery bag.’ And he’s like, ‘actually, the people who customize the box have shorter LTVs.’ Oh, okay. Well, I don’t want that. Ignore me.”

The founder could push back on his own investor because he could flex his operational fluency with data, and every pushback generated more investor confidence, not less.

What to do: Ask yourself when your finance team last challenged you on the plan rather than reporting on it. Then take Chris’s closing advice from the webinar: “If you wanna show up more confident, go get yourself challenged before the challenge. Have somebody beat your thesis up before you put it in front of the board. Who’s doing that for you?”

The bottom line

Confidence with your board comes down to operational fluency: knowing your numbers cold, reporting them honestly, and arriving with a plan rather than just a problem. Green lights don’t build investor confidence; accurate ones do. Pressure-test your understanding of what drives the business, and how you’ll communicate it, before you ever get into the boardroom, and surround yourself with a team that will challenge you to deliver the strongest story. The right finance team helps you do all of it.
