If you’re not one of their 500 million users, Duolingo is a phenomenally successful app where you practise a language in small chunks every day. Launched in 2012, it has become the number one language learning app and the most downloaded education app in the world. The company floated in 2021 and currently has a market cap of just under 4 billion dollars. It’s rare for a founder to be brilliant at both invention and business but Luis Von Ahn, the Co-Founder and CEO of Duolingo, is one of them. Before Duolingo, he invented Captcha - those squiggly letters you have to write out to prove you’re not a computer. The guy’s a genius, and that’s a fact. He actually won an award for being one in 2006, the prestigious Macarthur Fellows Program award. It’s colloquially known as the genius grant, because it’s said you have to be one to get it. Luis grew up in a single parent household in Guatemala. His mother spent all the money she could sending him to the best school she could afford. This experience, of seeing the difference between those who receive a good education and those who don’t, would later form the basis of Duolingo. But when Luis and his Co-Founder Severin started Duolingo in 2012 they had a big problem - how could they keep their users coming back?

Jay Radia has built three businesses worth over half a billion pounds and currently runs an accelerator focusing on increasing happiness in the workplace. But before all that, he founded a company called Mobi RF, which failed. The idea behind the company was to allow anyone with a smartphone to start selling their photos to businesses, like iStock or Getty Images for your smartphone. Jay had this spark of inspiration back in 2012 when Instagram was taking off and everyone was taking more and more photos on their phone. His confidence skyrocketed when he spoke to the Founder of iStock who told him the idea was incredible and that he wished he’d thought of it. He quit his six-figure job in finance and bootstrapped the company with his brother.What went wrong? Listen to find out. If you have any feedback, we’d love to hear it.

Before Mark Joseph founded his current marketing agency, Vouch Global, he experienced failure with another agency called Testify Digital. Their clients included brands like Universal, Wonderbra, Shock Absorber and Lenovo. He loved the projects they came up with, including the world’s first award judged on social media for the Mobo Awards. They got to £1m in revenue and Mark ran the company for five years before he reached the point where he felt he had to walk away. So, what went wrong?

Gareth Atkinson launched the Yorkshire Meatball Company in 2014 with his father after they recognised a gap in the market for a premium meatball product. They opened a restaurant in Harrogate, won awards, were listed as one of the UK’s top 100 startups, and ended up being stocked in 300 supermarkets across the country. Like all good entrepreneurs, they’d even built a brand that had the potential and scope to stretch into other markets.So what went wrong?

How do you build a metaverse? Long before Facebook changed to Meta, Improbable, a British game and technology company, was working on the idea of a kind of metaverse, even if they didn’t call it that. Now, they are at the forefront of making virtual worlds (where you can go to work, socialise, have experiences) a reality. Improbable was born in 2012 after Herman Narula met Co-Founder Rob Whitehead whilst they were both studying computer science at Cambridge University. They had a dream: they loved computer games and wanted to go live there. They spent over a decade working on how to do that and became a unicorn without anyone really knowing what they did.But it’s not all about entertainment, they also have another side of their business that has applications in defence and public policy. They build models of real world countries which can be used to solve a whole host of problems; from what would happen if a particular response to coronavirus is implemented, to how climate change might require the electrification of a grid. Herman is obviously a key part of the company’s success but he doesn’t want it to be all about him and warns against falling into the trap of the cult of personality such as that of Elon Musk. Instead, he says, if you are building an ambitious company, you need to be able to be open to failure and understand your limitations. And, he says, they have made many mistakes over the past decade but they were lucky because they were funded at a time when people could invest in technology companies that didn’t have a business model. Listen to find out why young tech companies that are looking to grow now shouldn’t expect the same luck; how virtual worlds will change the way we live our lives entirely; and why he says that the era of consolidated monopolies, such as Google, Facebook and Amazon, may be coming to an end. --SponsorsVorboss - get better internet: https://vorboss.com/secretleadersVanta - get 20% off security certifications like ISO27001 and SOC2: https://vanta.com/secretleadersVertice - save on your SaaS or cloud spend ($5k off or a free benchmark) using the code secretleaders: https://www.vertice.one/l/secretleaders--NewsletterSign up here: https://secretleaders.email/You can find our historic newsletters here: https://www.secretleaders.com/episodes Learn more about your ad choices.

Would you fight for your business even after you’d put it into administration? Radha Vyas co-founded Flash Pack, an adventure holiday company, with her husband Lee, after realising there was an untapped market for solo entrepreneurs in their thirties and forties. They slowly built their company and were just entering an exciting first fundraising round when the pandemic hit, decimating their company and the entire travel industry. They had to put the company into administration but then were offered a ray of hope which meant they might be able to get their business back.What happened next?

You want to launch a new product. But how do you decide on exactly what you’re going to develop? How do you build a community when you don’t have anything to sell them? How do you test demand? These are important questions that Dan Murray-Serter, the usual host of Secret Leaders, will be answering this week.This is the fourth chapter in our semi-regular series with Dan where we put him in the hot seat. If you haven’t listened to the previous three it’s worth doing that now because you’ll understand more about what he talks about in this episode. Dan is a founder himself. His day job is running his VC-backed company Heights. For this episode we are going back to the beginning of Heights. Well, actually, before the beginning, because whilst Heights is now a braincare supplement company, it didn’t start out as one. After the failure of their previous company in 2018, Dan and his co-founder Joel decided they wanted to focus on building a consumer goods company in the mental health field. They knew where they were pointing roughly and they were in the rare situation where they had money left over from their previous business, essentially their seed money. But how do you get from there to a product that people love?--SponsorsVorboss - get better internet: https://vorboss.com/secretleadersVanta - get 20% off security certifications like ISO27001 and SOC2: https://vanta.com/secretleadersVertice - save on your SaaS or cloud spend ($5k off or a free benchmark) using the code secretleaders: https://www.vertice.one/l/secretleaders--NewsletterSign up here: https://secretleaders.email/You can find our historic newsletters here: https://www.secretleaders.com/episodes Learn more about your ad choices.

Do you struggle to maintain good relationships with your employees? Hayden Bloomfield managed to grow his grounds maintenance company during the pandemic. At its height, it had a team of ten and was turning over £25,000 - £30,000 a month. But during a period of two years, Hayden went through thirty members of staff. He couldn’t focus on building the big picture because he regularly had to cover some staff not turning up for work. Why couldn’t he stop his staff from leaving? Listen to find out. If you have any feedback, we’d love to hear it.

Micha Kaufman is the Co-Founder and CEO of Fiverr, the global online marketplace for freelancers. Let’s say you’re a designer. You can list your services and display your portfolio. And then companies who want stuff designed like a new website can find you and hire you to do the work.It's called Fiverr because at the beginning all the tasks cost 5 dollars. Though the pricing has changed, the name has stayed and the platform is currently used by 4.2 million customers in 160 countries worldwide. The company launched in 2010 but Micha was committed to growing it organically so spent nothing on marketing for the first five or six years. And that is even more incredible when you think that Fiverr, which went public in 2019, has a current market cap of just under 1.4 billion dollars and revenue of over 160 million dollars this year so far. Micha says it’s three times larger than it was when it floated. But during the pandemic, they skyrocketed to a market cap of 11 billion dollars….yeah, we get into that period!As well as that, Micha tells me how being featured on Yahoo nearly ended Fiverr when it first launched; why he says their success is down to luck, and much more.--SponsorsVorboss - get better internet: https://vorboss.com/secretleadersVanta - get 20% off security certifications like ISO27001 and SOC2: https://vanta.com/secretleadersVertice - save on your SaaS or cloud spend ($5k off or a free benchmark) using the code secretleaders: https://www.vertice.one/l/secretleaders--NewsletterSign up here: https://secretleaders.email/You can find our historic newsletters here: https://www.secretleaders.com/episodes Learn more about your ad choices.

Would you go into business with a friend? Jo Fisher is the Founder and CEO of Footlights, a performing arts company, which has 17 franchises and works with schools across the north of England. She got into business at a ridiculously young age.

She left school at 14 to work full-time and launched her first business, an underwear business, when she was just 18. When it started to grow she decided to bring in her best friend as a partner…and that’s when things started to go wrong. What happened?
