Your heart drops. Is this it? Is this the moment the company dies?
Tom Bloomfield, entrepreneur, investor, and founder of Monzo.
I've never actually talked about this before. In six months, I just thought, "I can't work with this person." I just really, it's really damaging to me and my mental health, and so I resigned. And the response to that resignation, she called an all-hands meeting and fired the entire company. If I knew then what I knew now, I would never have done it, really. If I knew what the amount of pain and heartache that would be involved, I would never have started, but I didn't know that. I cry quite a lot. (laughs)
(laughs)
You know, I'm not ashamed of that. For about three or four seconds, I'd forgotten what my life was. I was calm, and then three or four seconds later, all the memories came back, and it was just like this crushing weight. That really was the moment I just sort of knew this is, this is no life. There were no other emotions in my life, really, apart from just anxiety. I mean, it was serious by the end. We would detect criminals and shut their accounts down. Customs would turn up sometimes with weapons, and they'd threaten to turn up with, you know, a bottle of acid and throw it in someone's face. That was tough.
Tom Bloomfield, what a remarkable entrepreneur. One of the UK's recent real success stories, and he and his team managed to disrupt the archaic incumbent banking system at a time when nobody thought it could be disrupted. But man, his story is crazy, absolutely crazy. And the reason why I started The Diary of a CEO is demonstrated perfectly in this podcast. It has it all, controversy, drama, business wars, depression, anxiety, resilience, success, and failure. And today, you're gonna hear a particular business story, one that's never been heard before. But Tom felt that today and here was the place to share it. If you're an aspiring entrepreneur and you want to get to the point in your life where you're running a hundred million or a billion-pound company, today might be your warning. Because as Tom is going to tell you, all that glitters isn't gold. And the true cost of entrepreneurship, the cost that nobody seems to talk about, is sometimes greater than the reward on offer. This is one of the most emotional, raw, honest, vulnerable, brilliant, gripping conversations I've ever had on this podcast. And I can't thank Tom enough for opening up his diary and allowing us to look inside. Without further ado, I'm Steven Bartlett, and this is The Diary of a CEO. I hope nobody's listening, but if you are, then please keep this to yourself. Tom, why, why entrepreneurship?
I made a very bad employee. (laughs)
(laughs)
I've never been promoted, and I've been fired, I would guess, two or three times, depending on how you count.
