What have been the most important lessons you’ve learned?
I've probably made all the mistakes that are possible to make. In terms of advice: a few things. First, talk to your customers from day one and test your ideas—even if you don't even have a product! Inventing some technology and hoping somebody will figure out a way to use it, will never fly. If your technology doesn’t solve a problem, or creates new services and grows businesses' top line, the technology is going to die.
How do you go about building a team to scale?
You need to always remember every piece of the company, be it finance or commercial or engineering or marketing, are fields in which you need experts. High skills in developing code are equally important to high skills in how to make a finance model. It's like a football team: the goalie probably doesn't score a lot but if you don't stop the other team from scoring, you won’t win the game.
The sooner you can bring in people that know their field, the faster you will be able to get to market and the fewer failures you will have. This starts with a good core team, either in the form of co-founders or early senior hires who can bring in other people and educate them.
Make sure you have good advisors around you. By ‘good’ I don’t mean people that are famous for being an expert in how things used to be—the market technology is changing too fast. Even if you find someone that was a superstar seven years ago, if they haven´t been in the game since then, they're not right for a startup.
