Tactical insights for first-time founders to outsmart the burn, the churn & the breakdown.
Hey Founder,
You love the graph going up: more revenue, more customers, more “we’re onto something.”
But then you get that weird split-screen: revenue is up, and your bank balance still feels tight.
Every new customer takes more work and leaves you with the same, or less.
That’s not you being bad with money, and it’s not something your revenue chart will fix.
The answer sits in a line most founders glance at and move past: gross profit, what’s actually left after delivering what you sold.
This issue is about using gross profit to tell if your growth is actually making you stronger, or slowly breaking your business.
Let's dive in.
The Margin
Gross Profit = How Much Room You Really Have
On paper, gross profit is simple: revenue minus the direct cost of delivering what you sell.
In reality, it answers a more important question: after delivering value, how much is actually left to run and grow the business?
That’s your room.
Room to hire, experiment, and say no to bad-fit customers.
If you look at your last 6–12 months, the trend tells you everything:
If gross profit is growing, each new customer is buying you more room.
If it’s flat, you’ve added motion, but not capacity.
If it’s shrinking, you’re buying growth and increasing pressure.
You can see this clearly in how different businesses scale.
When Toolkit was around ~$84k ARR, the math looked roughly like this: ~$9 revenue per user, ~$1 in direct costs, ~$8 in gross profit. Margins held as they grew.
That didn’t just mean people liked the product; it meant they had room, room to hire, spend on acquisition, and reinvest without pressure.
Compare that to a bootstrapped agency I worked with.
Revenue grew ~46% YoY to ~$5M, but gross margins stayed around ~44%. Every new client brought heavy onboarding and custom work.
Revenue said, “We’re growing fast.” |
Gross profit said, “This only works if you never slow down.”
When they finally paid attention, they paused hiring, dropped expansion plans, fixed the fundamentals, tightened scope, standardised onboarding, and focused on retention.
That’s the shift.
Gross profit tells you when growth is giving you room, and when it’s quietly taking it away.
Why You Should Care About Gross Profits
It tells you if your model works at a unit level.
Early on, total profit can be negative; that’s fine. What’s not fine is a model where every extra dollar of revenue requires almost a dollar to deliver.
Gross profit is the cleanest early check on whether a typical customer leaves enough behind to build on.
It changes what game you’re playing.
At ~40–50% gross margin, you’re in the services territory, people-heavy, expensive delivery.
At ~70–80%+, you’re closer to software; systems do most of the work, and delivery is cheap.
Same revenue, completely different outcomes: how investors see you, how much they’re willing to fund, and how hard your next round is.
If your story says “high-margin software” but your numbers say “services,” the gap shows up quickly, slower processes, more pushback, or no term sheet.
It’s also the only line you can safely build plans on.
Revenue can look strong while you’re burning, net profit can be adjusted short-term, gross profit is harder to hide and it’s what answers questions like:
Can we afford this hire?
Can we hold this price?
Can we survive if the next round takes longer?
And despite this, a lot of founders still avoid looking at it.
Let’s get into why.
Tiny Reframe
Revenue Is The Story. Gross Profit Is The Mirror.
Revenue is the story you tell: updates, screenshots, “we’re onto something.”
Gross profit is what the business tells you back: after all that work, what actually stayed?
Most founders treat it like a grade: high means you’re doing well, low means you ignore it and focus on the top line.
But gross profit isn’t grading you, it’s showing you what your current version of growth turns into.
If it compounds, you’re building optionality.
If it’s flat, you’re on a treadmill.
If it’s shrinking, you’re trading long-term health for short-term momentum.
So instead of asking, “Is this good or bad?”
Ask: What is this growth actually turning me into?
How Founders Miscalculate Gross Profit.
(And End Up Living in a Business That Doesn’t Exist)
After 10+ years inside the P&Ls of early and growth-stage companies, I see the same two patterns over and over.
Pattern #1: Everything is OpEx
COGS is basically empty.
Gross margins show up as 90–100%.
Pattern #2: The half-honest COGS line
You do have COGS, but a lot of what belongs there sits in OpEx: support, onboarding, infra, and delivery contractors.
So your gross margin shows 70%… when it’s actually closer to 45%.
And that’s where things break. You start making hiring and pricing decisions off the wrong number, and telling a “software-like margins” story that doesn’t hold up under scrutiny.
The rule I use is simple: If you had zero customers, would this cost still exist?
If not, it’s COGS.
If yes, it’s OpEx.
Until you run that test honestly, your gross profit line is describing a business that doesn’t exist.
3 Margin Moves To See What Your Growth Is Really Doing
1. Draw your “room” line.
Pull your monthly gross profit (in dollars) for the last 6–12 months and plot it.
Ignore revenue for a moment and just ask: Is your room expanding, flat, or shrinking?
Then be honest about what that means:
If it’s expanding, where can you be braver?
If it’s flat, where are you working harder for the same outcome?
If it’s shrinking, where are you quietly buying growth?
2. Clean up your COGS with the zero‑customer test.
Take your biggest costs and run one simple test: If you had zero customers, would this still exist?
If not, it belongs in COGS.Then recalculate your gross profit and margin.
You’ll end up with two numbers: the one you’ve been using, and the one that’s actually true.
Make decisions based on the second one.
3. Add one question to your monthly review
After looking at revenue, ask: Did gross profit grow faster, slower, or the same?
If it’s faster, you’re compounding room.
If it’s the same, you’re on a treadmill.
If it’s slower, you’re buying growth.
Then act on it. Tighten scope, raise prices, or walk away from deals that look good but hurt your margins.
You don’t fix this by staring at the number. You fix it by changing the behaviour behind it.
Tough Love Corner
A founder sent me this:
“An investor just sent a term sheet, lower valuation, board seat, and pro rata that locks the next round. We’ve got 5–6 months of runway, no other offers, and my cofounder wants to just sign. How do I push back without blowing this up?”
You don’t have much leverage here. So this isn’t about “winning”, it’s about not boxing in your future.
Get on a call, show you’re excited, and pick one or two things to push on, not everything.
The board is usually first. Keep it simple, either a 3-person board or start with an observer and revisit later.
On a pro rata basis, the standard is fine. What you don’t want is anything that pre-allocates your next round.
On valuation, make one clear, data-backed ask, then stop.
The goal isn’t to squeeze terms, it’s to avoid signing something your future Series A lead will hate.

Founder’s Toolbox
High-value reads this week:
Before you go…
Not all progress is worth keeping. Some of it just adds weight you’ll carry later.
Choose the kind that strengthens your foundations, not the kind that needs constant rescue.
That’s your real moat.
