Why Experience Can Make a Founder Less Willing to Try

Blomfield says naivety and self-confidence helped him attempt a regulated banking startup despite the odds. He argues that experience can become baggage when repeated exposure to failed models prevents an investor or founder from noticing changed timing, teams, or technology.

  • Blomfield credits both confidence and naivety for starting Monzo
  • Prior failures can make people dismiss a model too quickly
  • A changed team, technology, or moment can alter the result
  • Optimism still needs enough self-awareness to hear useful feedback

i had a huge amount of self-confidence huge amount of naivety and just assumed that i could figure it out

Ignore the Hype Before You Need to Ignore the Backlash

Blomfield describes UK press coverage shifting from enthusiastic praise of Monzo to persistent negative framing as the company became more prominent. His advice is to avoid internalizing either phase because he considers both the flattering and hostile versions exaggerated.

  • Blomfield says Monzo was first built up and later attacked
  • A journalist told him Monzo headlines attracted more subscribers
  • Positive coverage can be as detached from reality as negative coverage
  • His recommended response is to stop reading both

don't read the good stuff or the you know just ignore it all basically

What Changed When Monzo Grew Toward 2,000 People

Blomfield says the close culture he knew at 100 or 200 people became harder to sustain near 2,000. Teams developed separate narratives, some senior leaders built internal domains, and practices imported from large banks sometimes produced rivalry instead of collaboration.

  • Leaders could no longer know everyone personally
  • Subcultures formed around each team's view of its purpose
  • Some teams framed themselves as protecting the company from others
  • Blomfield found the resulting organizational politics unfamiliar and difficult

you get subcultures so teams develop their own sort of internal narrative

The Starling Rupture That Preceded Monzo

Blomfield gives his account of resigning from Starling after six difficult months and says the founder then dismissed almost the entire team. The former colleagues gathered at a gin bar, considered their options, and eventually decided to rebuild the banking work themselves as the company that became Monzo.

  • Blomfield says the working relationship was harming his mental health
  • He characterizes his departure as a resignation rather than a team raid
  • Thirteen of Starling's fourteen team members later joined the new venture
  • Rebuilding forced the team to redo code and regulatory submissions

we think we can do this ourselves

Success Weakened Blomfield's Need to Prove Himself

Blomfield traces part of his drive to childhood insecurity, money, and a desire to be seen as successful. After experiencing public recognition through Monzo, he says that need diminished; he now focuses more on day-to-day enjoyment and questions fresh ambitions before accepting their cost.

  • He links early ambition partly to insecurity and external validation
  • Recognition felt rewarding but did not become an enduring purpose
  • He now pauses when a new status-driven ambition appears
  • Financial independence makes a calmer life a practical choice

that need to prove myself has sort of disappeared actually

The Pandemic Shock That Made Blomfield Step Back

Blomfield says several problems had already made the CEO role unhappy for roughly one or two years before the pandemic. He reports that Monzo's revenue fell sharply, an expected funding round lost its terms, and weeks of seven-day work with poor sleep became the final pressure that led him to ask to be replaced.

  • The departure followed accumulated strain rather than one isolated event
  • Blomfield had discussed his dissatisfaction with board members and investors
  • He says senior leadership gaps left him covering several jobs
  • COVID-19 was the final shock rather than the sole cause

covid was definitely the straw that broke the camel's back

Blomfield's Account of Anxiety, Poor Sleep, and Relief After Leaving

Blomfield describes waking early with work problems, feeling persistently anxious, and experiencing what he calls deep anxiety and being near depression. This is his personal account, not a clinical diagnosis. He says his sleep improved rapidly after leaving Monzo, which he interpreted as evidence that the job was a major source of the distress.

  • He describes a cycle in which fatigue worsened decisions and created more problems
  • He reports waking after calm seconds into an immediate sense of pressure
  • He estimates the severe period lasted around 18 months to two years
  • He says the symptoms eased soon after his departure

there were no other emotions in my life really apart from just anxiety

The Pink Phone That Meant Monzo Might Be in Serious Trouble

To keep his normal mobile outside the bedroom, Blomfield used a separate old Nokia connected only to Monzo's incident escalation system. When it rang every few months, he knew a serious outage had reached the CEO and could require calls to the board, investors, or regulators while engineers handled the technical repair.

  • The emergency phone separated routine notifications from critical alerts
  • Only the automated escalation system had its number
  • Some incidents left the CEO responsible for communication but unable to fix the system directly
  • The uncertainty made each call feel potentially existential

The Hidden Threats Behind Monzo's Fraud Controls

Blomfield says Monzo employees received threats after the bank froze accounts while trying to prevent financial crime, and that the company maintained office security. He also acknowledges that legitimate customers were sometimes blocked and could face long waits because of errors and legal reporting requirements.

  • Some threats reportedly included weapons and acid violence
  • Blomfield says angry amateur criminals were often more confrontational than organized groups
  • Monzo used pattern detection and worked with law enforcement
  • He describes cases involving fuel theft and suspected human trafficking
  • He concedes that some legitimate customers were incorrectly blocked

we would detect criminals and shut their accounts down

Blomfield Credits Privilege for Making Big Risks Possible

Blomfield describes himself as confident and impulsive, but refuses to present those traits as the whole explanation for his choices. He says supportive parents, education, and a fallback made it safer for him to quit jobs and pursue uncertain opportunities.

  • Risk tolerance is partly enabled by the consequences of failure
  • Blomfield identifies family support and education as advantages
  • His rapid career decisions were not made from equal starting conditions
  • Founder stories can obscure the safety nets behind apparent fearlessness

that was enabled from a place of huge privilege because i could take the risk

Monzo's Founding Team Was Stronger Than Its Selection Process

Blomfield calls the core team a major determinant of success, but says Monzo's mix of skills was largely inherited from the Starling breakup rather than deliberately assembled. He contrasts it with a university venture whose fourteen co-founders produced meetings but little work until three committed operators took responsibility.

  • Blomfield views the core team as a major success factor
  • Monzo benefited from a varied group that already existed
  • A large nominal founding group can diffuse responsibility
  • Commitment and complementary skills matter more than founder labels

it's probably the single biggest determining factor of successful failure in my view

The Detachment Blomfield Wishes He Had Learned Earlier

Blomfield says he could not stop identifying emotionally with Monzo, even away from work. He contrasts himself with colleagues who could be fully present at work, switch off at home, and recognize that their personal survival did not depend on the company's outcome.

  • Working hours were less damaging than the inability to switch off
  • Blomfield observed other leaders compartmentalize work and home life
  • He considers some emotional distance healthy rather than uncaring
  • Separating personal identity from company identity reduced the perceived stakes

your entire person is not intrinsically linked to this company

How Blomfield Rebuilt a Busy Life Without High Stakes

After an initially disorienting exit during lockdown, Blomfield returned to a long-standing list of things he wanted to learn. Drawing, languages, kite surfing, sailing, flying, volunteering, and angel investing gave him activity and novelty without recreating the obligations of running a large company.

  • An empty calendar initially felt strange after a tightly scheduled CEO role
  • A pre-existing learning list gave him concrete next activities
  • He values moving from novice to competent beginner
  • His new commitments can usually be cancelled or left without severe consequences

it's busy but it's low low pressure i guess

The Founder Upside Blomfield Still Believes In

Blomfield does not reject entrepreneurship despite its cost. He values choosing collaborators, creating something people use, and gaining financial independence, but says he failed to monitor whether achievement was making him happy and now considers that omission a mistake.

  • Founding can create value and personal wealth
  • The founder can choose many of the people around them
  • Seeing strangers use a product is a distinctive reward
  • Blomfield would change parts of the journey but does not regret it
  • He now treats happiness as a present input rather than a deferred outcome

i never paid enough attention to whether i was happy
