Sustainable High Performance and the Limits of the Hustle Culture
For more than a decade, hustle culture has shaped what serious entrepreneurship is supposed to look like. Long hours. Constant urgency. Personal sacrifice reframed as commitment.
For a while, this model appeared to work. It aligned with an era of abundant capital, shorter funding cycles, and rapid exits. Intensity could mask inefficiency, and exhaustion was often mistaken for momentum.
“Hustle culture makes it the norm to burnout and suck it up.”
That context has changed.
Today’s founders are navigating longer runways, tighter capital, higher complexity, and greater personal exposure. Under these conditions, hustle is no longer a performance strategy. It is a structural liability.
This article is not an argument against ambition or effort. It is a correction to how performance itself has been defined in entrepreneurship.
We will examine how hustle culture came to dominate, why it systematically undermines founder effectiveness, and why sustainable high performance is emerging as the only model that holds up under modern conditions.
Not because it is softer, but because it is more precise, more durable, and more aligned with how human performance actually works.
Why sustainable high performance matters now
The quiet strain behind outward success
Founder strain is no longer an exception. It is the baseline.
In 2024, Foundology reported that 93 percent of founders show signs of mental health strain, with 55 percent experiencing symptoms weekly or daily.
Techstars similarly found that 78 percent of founders report high stress and 70 percent report anxiety, even while continuing to scale their companies.
The defining feature of this moment is not struggle. It is the coexistence of outward success and inward erosion.
Revenue growth and personal depletion are happening simultaneously. Cognitive clarity, emotional regulation, and decision quality are degrading before performance visibly declines. But it inevitably does.
Sustainable high performance matters now because this erosion compounds quietly. By the time it appears in missed targets or board tension, the underlying capacity loss has often been accumulating for years.
When high performance means harder and longer, not smarter
In much of the startup ecosystem, performance is still measured by intensity.
Techstars reports that 31 percent of founders work more than 60 hours per week, and 17 percent work over 70 hours.
Hours become shorthand for seriousness. Availability becomes evidence of leadership. Pressure becomes proof of commitment.
This definition of performance is outdated.
It rewards visible effort over effective thinking and activity over outcomes. Under current conditions, it produces fragility rather than advantage.
Hustle culture and how it shapes our idea of performance
The historical roots of hustle thinking
Hustle culture did not emerge because it was optimal. It emerged because it was convenient.
Older industrial ideas equated productivity with time spent and moral worth with effort. Venture capital layered urgency on top, reinforcing speed as survival.
In a Balderton Capital survey, 82 percent of founders said they believe long working hours are inevitable in entrepreneurship
What began as a situational response hardened into an identity. Hustle stopped being a tactic and became a requirement.
Silicon Valley narratives and hero stories
Silicon Valley amplified this mindset through hero-founder narratives that celebrate sacrifice without context.
Burnout, health crises, leadership breakdowns, and forced exits are rarely part of the story. What remains is a distorted template that equates suffering with seriousness and success.
Founders absorb this early. To rest feels risky. To slow down feels irresponsible. Especially with external capital.
Core tenets of hustle culture
-
Balderton found that 83 percent of founders believe there are diminishing returns to working more hours, yet many continue anyway. This persistence is not ignorance. It is pressure.
-
51 percent of founders say investors and board members pressure them to be constantly available. Availability becomes a proxy for reliability, even when it undermines reliability over time.
-
One founder described the norm plainly: “Hustle culture makes it the norm to burnout and suck it up.” When pressure is praised, recovery feels illegitimate.
The limits of hustle culture for founders
When intensity stops translating into output
The belief that more hours produce more output does not survive scientific scrutiny however.
Stanford economist John Pencavel found that productivity drops sharply after 50 hours per week, and that 70-hour weeks produce little to no additional output compared to 55-hour weeks
Beyond this threshold, effort degrades performance. Errors increase. Thinking slows. Rework multiplies.
Hustle does not maximise output. It exhausts capacity, and it makes good decision-making unlikely.
The hidden opportunity cost of chronic overwork
Chronic overwork reshapes how founders evaluate risk.
Balderton’s 2024 report found that 23 percent of founders say personal financial stress makes them less willing to take business risks.
Stress narrows perception. Founders choose safer paths not because they are strategically superior, but because depleted systems struggle to tolerate uncertainty. Innovation suffers quietly in the background.
Why more hours often reduce strategic clarity and decision-making
88 percent of founders agree that excessive stress leads to bad decision-making
As one founder described:
“Under pressure I become reactive rather than strategic. I struggle to think clearly about long-term direction and end up firefighting instead of building.”
Strategic thinking requires cognitive space. Hustle culture removes it.
Founder mental health is a performance issue
Cognitive load, emotional regulation, and decision quality
From a biological standpoint, hustle culture undermines the exact functions founders are paid to perform. Chronic stress impairs the prefrontal cortex, reducing executive control, working memory, and emotional regulation [Source: https://www.nature.com/articles/nrn2648].
When this system is compromised, founders struggle to allocate capital, set strategy, hire well, and navigate ambiguity. Hustle does not simply feel hard. It disables high-level thinking.
Stress as a drag on creativity, leadership, and risk assessment
Research published in Frontiers in Psychology shows that stress shifts decision-making from deliberate to habitual patterns, increasing impulsivity and narrowing attention [Source: https://www.frontiersin.org/articles/10.3389/fpsyg.2015.01101/full].
Under pressure, founders default to short-term fixes. Creativity declines. Leadership presence erodes. Risk assessment becomes distorted.
These outcomes are predictable, not personal.
Why founder breakdowns rarely appear suddenly
Founder breakdowns are rarely sudden. They are slow erosions misinterpreted as resilience.
Foundology’s data showing weekly or daily symptoms in over half of founders confirms this pattern. By the time a founder steps away, performance has usually been compromised for a long time. This, to the detriment of the founder, the company, as well as the VCs funding the journey.
The overlooked potential impact on VC returns
Founders as the primary asset
Venture capital often says it invests in founders, not just ideas.
Balderton Capital states it clearly:
“Founder wellbeing is not just a personal issue, it is a business performance issue. Healthier founders build healthier businesses.”
If founders are the primary asset, founder capacity is a financial variable worth investing in.
Attrition, burnout, and execution risk
Octopus Ventures reports that 65 percent of startup failures are linked to internal issues such as founder burnout and conflict
Burnout increases execution errors, leadership turnover, and stalled momentum. It also increases the likelihood of co-founder conflicts. These risks compound across portfolios.
A simple portfolio returns math
Burnout affects returns through three compounding mechanisms:
Reduced decision quality
Slower execution
Increased failure probability
Venture models price market, technical, and execution risk. Founder cognitive and emotional capacity affects all three, yet it is rarely measured or managed explicitly.
In a world where VC portfolio returns often rely on one startup out of 10 becoming a 100x investment, it is very obvious that should that one company suffer a founder burnout, it puts the whole portfolio at risk! Yet, very few VCs invest in their portfolio founders’ mental health.
Why neglecting founder mental health erodes long-term returns
Despite the stakes, founders rarely turn to investors for personal support.
Balderton found that only 2 percent of founders often turn to investors for personal support, while 88 percent rarely or never do.
Risk accumulates where it is not observed, and the current environment and expectations make it next to impossible for founders to seek support.
Why hustle culture feels so convincing
Conscious drivers: when you think your way into burnout
Peer comparison, industry narratives, and social validation reinforce hustle. Visible effort feels safer than invisible thinking. Exhaustion is easier to justify than boundaries.
Subconscious drivers: when your mind just feels like overwork is the answer
Hustle culture persists because it feels protective.
Early beliefs about worth, achievement as safety, and the thought “If I work harder, no one can say I did not try” operate beneath conscious reasoning. This is why information alone rarely changes behaviour.
Some VC funds are supporting sustainable high performance
Some funds are already adjusting their assumptions.
Felicis Ventures commits 1 percent of every first cheque to founder coaching, therapy, and performance support.
Others, such as Balderton Capital go even further with a full-fledged Wellbeing programme that span Health & Fitness, Executive Coaching, Parental Support and much more.
This reflects a nascent shift in performance logic, not generosity.
Our definition of sustainable high performance at Holorise
Performance built on clarity, regulation, and alignment
At Holorise, sustainable high performance means designing conditions where clarity replaces urgency, regulation replaces reactivity, and effort aligns with outcomes.
Mental health as a prerequisite, not an afterthought
Mental health is not an add-on. It is the foundation of decision quality, leadership presence, and strategic thinking.
Physical health as a baseline of business performance
Sleep, movement, and recovery underpin cognitive capacity. Without them, performance becomes fragile regardless of ambition.

Final reflection
Hustle culture promised success through sacrifice. Under modern conditions, it delivers fragile performance and shrinking capacity.
Sustainable high performance is not an alternative philosophy. It is a correction.
The question is no longer whether hustle culture works.
It is how long founders and investors can afford to pretend that it does.
