Participating in Y Combinator was a 'resetting moment' for Tom. It showed him the much higher caliber of people, ideas, and execution required for success, pushing him and his team to pivot from a weak idea into a stronger B2B payment solution for GoCardless.

Why did Tom Blomfield leave GoCardless?

Key Moments

TL;DR

Founding two billion-dollar fintechs was a wild ride, but burnout and near-collapse almost ended it all, forcing a difficult step back to survive.

Key Insights

Tom Blomfield pivoted go-cardless from a 'tarpit' bill splitting idea to a B2B payment solution after Y Combinator's mentorship highlighted a higher bar for execution.

Monzo grew to 1 million customers in 2.5 years without advertising, primarily through word-of-mouth, fueled by a 'hot coral' card and a delightful user experience.

During the COVID-19 pandemic, Monzo faced a 50% revenue drop and the withdrawal of a critical $100 million funding round, leading to discussions about winding down the company.

The immense pressure of potential outages at Monzo, where minutes of downtime could halt tens of thousands of payments, was a primary concern, exacerbated by negative press cycles like the BBC's ice sculpture stunt.

Despite facing severe anxiety and burnout, Blomfield eventually stepped back from Monzo, a decision he described as letting go of a huge part of his identity.

After stepping back from Monzo, Blomfield became an angel investor, making approximately 75 investments in nine months, before joining Y Combinator as a Group Partner.

The allure of creation and the entrepreneurial path

Everyone interacts with structures like buildings, transportation, and laws, which are all created by people. Tom Blomfield highlights a choice: either live within these structures by following the rules, or take an alternative path to create something new, have an impact, and change the rules. This path, chosen by Blomfield as a founder of go-cardless and Monzo, offers the reward of creating products millions use and love, but comes with extreme emotional highs and lows. He emphasizes that no founder truly understands how difficult it will be until they experience it. Blomfield's companies aim to last for the next 100 years, reflecting a grand vision for impact.

Early fascination with computers and a detour into law

Blomfield's interest in computers began at age seven with an Apple II, playing a game about maximizing lemonade stand profits. By 15, he was building websites for local businesses, though he didn't initially consider it a viable career due to a lack of visible role models. Influenced by his parents, he pursued law at Oxford, a seemingly safe and respectable path with a predictable career trajectory. However, he found the law degree too narrow, desiring to learn about different businesses and figure out how the world worked, with the eventual goal of starting something himself. While at Oxford, he co-founded an online student marketplace alongside his law degree, but ultimately dropped out of the startup to complete his final exams.

Y Combinator's pivotal role in pivoting go-cardless

After graduating law school, Blomfield connected with co-founders Matt and Hero, who initially planned a dating website. They convinced him to pivot to a bill-splitting app, a concept they later realized was a 'classic tarpit idea.' Their application to Y Combinator (YC) was a 'resetting moment.' YC revealed a much higher standard for caliber, ideas, and execution than they had anticipated, making them realize they were 'play acting' at running a startup in London. This experience pushed them to work much harder and focus. They quickly pivoted from the bill-splitting app to a more viable B2B payment idea, which became go-cardless. This mentorship and realization of a higher bar were crucial for their subsequent success.

The slow grind and personal disconnect with go-cardless

Following their YC experience, Blomfield and his team launched go-cardless in London. Growth was slow for the first year or two, requiring persistent effort to acquire customers month after month. However, Blomfield personally struggled with go-cardless because he had never managed a small business collecting money and couldn't empathize with the customers' needs. The problem they were solving didn't resonate deeply with him, despite loving the business and his colleagues. After three years, he decided to leave the company, recognizing it wasn't where he wanted to commit the next five to ten years. Go-cardless continued under his co-founders, eventually becoming a major payment processor handling billions of dollars globally.

Founding Monzo to fix a broken banking system

Driven by a desire to 'swing bigger' and address problems he saw as broken, Blomfield turned his attention to the banking space. He, along with co-founders Matt and Hero, started Monzo in early 2015, identifying banking as 'excruciatingly painful' with outdated interfaces and a lack of understanding from incumbents about software's potential. Their naive but accurate view was that rebuilding a bank from scratch with software could make it function better. Leveraging YC principles like 'launch early' and 'do things that don't scale,' they rapidly developed a prototype bank on a prepaid debit card within four months. This allowed them to get the product into users' hands quickly, a strategy that proved highly effective.

Monzo's explosive growth and the challenge of operational scale

Monzo experienced rapid user growth, reaching one million customers in about 2.5 years without any advertising spend, primarily through word-of-mouth. The 'hot coral' card triggered immediate notifications, creating buzz. A key to success was the ambitious vision of starting a bank from scratch, which attracted top talent, media attention, and excited customers. The user experience was also described as 'delightful,' encouraging referrals. However, this rocket-ship growth came with immense operational challenges. The team spent considerable time monitoring illegal activities, financial crime, and money laundering. Threats of violence and attempts to find personal information were common. The most significant pressure stemmed from processing $50-$100 billion pounds of payments annually; even brief outages could halt thousands of payments, impacting people's livelihoods and paychecks. Despite working intensely, Monzo experienced outages lasting minutes or hours, leading to negative press, famously including a BBC ice sculpture depicting a frozen Monzo card.

Burnout, near-collapse during COVID-19, and stepping back

The intense pressure and anxiety from operating Monzo took a significant toll on Blomfield, leading to sleepless nights and constant worry. The COVID-19 pandemic exacerbated these issues, causing a 50% drop in revenue as international card usageplummeted. Crucially, a vital $100 million funding round, agreed upon after nine months of global investor outreach, was pulled just before its scheduled closing, leaving the company on the brink of collapse. Regulators were concerned, and the company was advised to prepare for winding down. Despite working 16-17 hour days, seven days a week to find new revenue and cut costs, Blomfield reached his breaking point. He realized he needed to step away from the company, a significant part of his identity, to survive. He communicated this urgency to investors, stating he had only weeks left, and eventually stepped back, grateful for a new CEO and COO who, along with the existing team, carried Monzo through this crisis. Monzo has since grown to over 8 million customers and achieved profitability.

Transition to angel investing and returning to Y Combinator

After leaving Monzo, Blomfield took a year to recover. He then engaged with a previous investor's fintech startup, offering advice. This interaction, where he felt his 'brain coming back to life' by helping a founder navigate challenges, sparked a passion for early-stage investing. He became an angel investor rapidly, making around 75 investments in nine months. This extensive engagement with founders and hard problems led to an invitation from Y Combinator to consider full-time investing. He joined YC as a visiting partner, later becoming a full Group Partner, feeling it was 'like coming home' and a way to give back to the community that had been pivotal to his career. He now aims to help the next generation of founders create and grow businesses.
