    Why Most Startup Advice Is Wrong - with Matthew Cleevely

    What happens after you build, scale and sell a start-up - and how does the experience change the way you think about entrepreneurship? Matthew Cleevely returns to the ideaSpace Podcast four and a half years after his first appearance, when he was still building 10to8. Since then, he has exited the company and gone on to work with, advise and invest in other founders. He's also written The Founder’s Map: Volume 1: Building the Machine, which brings together the lessons he's learned along the way. In this conversation, Matthew and Ben explore the realities of life after an exit, why so much start-up advice can be misleading, and the uncomfortable role that luck and survivor bias can play. They also dig into some of the less glamorous, but hugely important parts of building a startup: boards and governance, hiring, company culture, documentation and putting the right foundations in place early. Matthew talks candidly about the mistakes he made building 10to8, including a culture that became toxic, the experience of running out of money, and the “phantom stress” that remained even after selling the company. They also discuss the importance of founder communities, why Matthew describes ideaSpace as a “platform, foundation and lifeboat”, and finish with a deceptively simple question: what does it actually mean to be a successful founder? A candid conversation about the bits of entrepreneurship that don't always make it into the success stories.

    The Mathematician Who Built a Hedge Fund - with Dr Ewan Kirk

    Ewan Kirk is a mathematician, programmer, hedge fund founder, investor, and philanthropist - and proof that the most interesting careers rarely go to plan. He set out to be a research scientist. Instead he ended up at Goldman Sachs, founded one of the world's leading quantitative hedge funds, and then walked away to do something more interesting. In this episode, Ewan talks about his first entrepreneurial venture - a CAD software company built in his bedroom in the mid-eighties - and what it taught him about selling. He shares what it was really like to arrive at Goldman Sachs knowing nothing about finance, how he built Cantab Capital Partners from a blank sheet of paper into a multi-billion dollar fund, and what happened when it all nearly fell apart in 2013. We also get into leadership, luck, and why he thinks most successful people dramatically overestimate how much credit they deserve. Plus his philosophy on philanthropy - and why he thinks giving money to safe projects is a waste of everyone's time. If you're a founder, an entrepreneur, or just someone trying to build something that matters, this one's for you.
