Please introduce yourselves: What does your startup do?

FLASH is a functional drink that cheers up without caffeine. A flavoursome sparkling mix of passion fruit, lemon, grapefruit with a spicy note of ginger, turmeric and pepper enhances your brain performance, reduces fatigue and protects the cells in your body from oxidative stress.

How did you come up with an idea and concept? What inspired and motivated you to create this product?

A few years ago, we started producing multifunctional cell tonics that enhance focus and boost energy level. FLASH is our new product, a tasty and functional soft drink in an attractive bottle.

What is unique about your business idea and operating model?

FLASH cheers you up without overstimulating. In times of self-optimization, we focus primarily on self-care. And while most of the popular food and beverage brands are produced by big corporations, we managed to create a competitive product as an independent small business. FLASH is one of a kind.

What were the most significant difficulties you had to overcome while building your startup?

All the small businesses have to deal with the fact that the market is geared towards big players, whether it's distribution, production capacity, order quantities or access to premises.

Where do you see yourselves and your company in 5 years?

Our product will be the European leader among natural and sustainable energy drinks. And we will keep working as freely and joyfully as we do now.

What are your expectations from the NX-Food Startup Shelf Program?

Of course, we would be happy to get a permanent listing at METRO. We wish that restaurateurs and small businesses get to know our products because in these independent companies we see our potential partners.
