How to Build a High Value Start Up- Expert.

Building a high-value business takes patience and entrepreneurs shouldn’t believe that start-ups reach multi-million-dollar valuations overnight, a successful Danish businesswoman has warned.

When it comes to growing a start-up, Mette Lykke, CEO of food waste organization Too Good To Go, speaks from experience.

She co-founded fitness app Endomondo in 2007, developing the company for almost a decade before it gained enough interest to be acquired by American firm Under Armour.

Endomondo was sold to the U.S. athleticwear brand in 2015 for $85 million, and Lykke stayed on as its CEO until 2017.

According to Lykke, who began her career as a management consultant, a business can only experience vast growth rates if the people at its reins exercise what she calls “patient impatience.”

“Every day you have to push (yourself) and you have to be willing to do that for quite a while,” she said. “I think a lot of stories about start-ups give the impression that two guys start a company in a basement and boom, two years later they change the world. That’s just not how it works – it takes years, so working hard every day is crucial.”

Be clear on your purpose

For the past two years, Lykke has been the CEO of Too Good To Go — an organization that works with restaurants and food retailers to tackle waste by selling food at a discounted price. The app has 11 million users and works with 22,000 stores across 11 countries

Her involvement with the company began around 9 months after the service was launched, when a friend who knew its founders showed her the app.

“I thought it was such a cool concept,” she told CNBC. “I got invited to invest and then was asked to help the founders run the business.”

She said her core driving force when it came to work was being part of a company that had a strong purpose and could make a real impact.

“I work a lot and put everything into it, so I want to do something that really matters,” she explained. “My first company was designed to make fitness fun, and now I have an even stronger purpose in tackling food waste. I just hadn’t realized the scale of this problem, but it had always been natural to me not to throw away food.”

Entrepreneurs looking to grow a company needed to follow her lead and work on something that they felt was meaningful, Lykke added.

“Make sure you’re really, really passionate about what you do — that’s fundamental,” she said. “There are going to be days and nights where, if you don’t have that passion, it’s going to be too difficult.”
