Introduction

Joyce and Raissa de Hass used to make tonic waters and mixers for their friends. That passion became a university project, which then turned into a successful start-up.

In the early days, the twin co-founders from the Netherlands were releasing batches of products they weren't really keen on, but now they think they've found a winning formula for premium mixers. They've won awards for their drinks, and now stock several premium bars and supermarkets.

In this edition of Business Daily, we hear how Joyce and Raissa turned a passion project into a business, why they believe they're shaking up the drinks industry, and what it's like to run a start-up with your identical twin.
