Jay-Z headlined a $68.1 million company festival in downtown Oakland late in 2025, playing to 8,000 Block employees flown in from around the world. Five months later, Block cut 4,000 of those jobs. Block did not have a culture problem. It had a ratio problem, one that a British historian named in 1960.
The Platitude
"Invest in your culture and the returns will follow." If you have run a team of any size, you have heard some version of this. It sounds right. Strong culture holds good people. Good people build good products. The logic is clean. But the logic has no number tied to it. Spending without a number is not investment. It is a habit.
The Miss
The festival landed in a quarter where Block missed revenue by 3.5% and missed adjusted earnings per share by 19%. The $68.1 million was not a victory lap. It was discretionary cost during a down quarter. A company filing noted the figure was roughly equal to the annual payroll of 200 employees. That is the kind of math that gets quiet fast.
The Mechanism
In 1960, Cyril Northcote Parkinson published his Second Law: expenditure rises to meet income. Not because people are greedy. Because systems without a ceiling will always find room to spend.
Block's filed numbers prove it. The payments company had 3,835 employees at the end of 2019. By 2023, that number had grown to roughly 13,000, a 3.4x increase in under four years. Gross profit per employee held flat at $500,000 the entire time. The company tripled its people and got the same output per head. Jack Dorsey later told staff plainly: "I incorrectly built 2 separate company structures rather than 1."
The Exception
Not every firm fell into the same trap. Apple added 7.3% to its workforce in 2020, the peak year of the hiring surge. The next two years came in lower: 4.8%, then 6.5%. Never double digits. Apple never announced mass layoffs. The companies that tripled headcount during the boom were the ones cutting 30% to 40% a few years later. The pattern was a management choice, not an industry condition.
The Structural Flaw
Most people treat this as a leadership flaw. It is a system flaw. The problem is not that Block spent money on its people. The problem is that spending replaced measurement. When gross profit per head stays flat through a 3.4x expansion, the system adds mass, not output. No amount of culture spend fixes that ratio. It just hides it.
The Replacement
The better rule: tie every dollar of discretionary spend to gross profit per employee. Not revenue. Not headcount growth. Gross profit divided by the number of people it took to produce it.
Block's own COO, Amrita Ahuja, named this as the company's north-star correction in a Fortune interview. After the cuts, the number moved. It climbed to $750,000 per employee in 2024, then $1 million in 2025. If Block hits its 2026 targets, the figure reaches roughly $2 million per head. The ratio did what the festival could not. It made the next dollar of spend earn its place.
Once that is clear, three moves follow from it.
Move 1: Run the Baseline Audit
Pull your gross profit from last quarter. Divide it by the number of people who touched the work: full-time, part-time, contract. That single number is your starting point. Most operators who run this for the first time find the figure is lower than they assumed, because they have been tracking revenue, not what stays after direct costs.
Move 2: Set the Ratio Cap
Pick a floor for gross profit per person. Any discretionary cost that pushes the ratio below that floor gets held until the next quarter. This is not a budget. It is a constraint. A budget tells you how much you can spend. A constraint tells you when spending has to stop.
Move 3: Retest Every 90 Days
Run the same math each quarter. The number either holds, climbs, or drops. If it drops two quarters in a row, something in the operation is adding cost without adding output. That is the signal. Not revenue growth. Not team morale surveys. The ratio.
What the System Shows
Running this for two quarters does something the culture advice never did:
It shows which roles produce gross profit and which roles service other roles. It shows whether a new hire added output or added coordination cost. It shows whether that offsite, that new tool, that team retreat moved the number or just moved the mood. And it makes the next spending call simple: does this hold the ratio or break it?
The Feedback Loop
At the end of each quarter, ask three things.
→ What moved the gross-profit-per-person number up?
→ What looked like progress but left no trace in the ratio?
→ What cost showed up more than once without a tie to output?
That is the difference between advice that sounds right and a system that proves itself.
Where You Stand
Late in 2025, 8,000 people sat in front of a stage in Oakland watching Jay-Z play on their employer's dime. Five months later, 4,000 of them were gone. The festival was not the cause. The missing ratio was. Culture is not what you spend. It is what the spending produces per person who shows up.
