Jakub Krejčík, 33, is the head and co-founder of Heaven Labs, the
producer of the MANA nutritional product, which went from being a hobby to
a major business. MANA is specially-designed food in liquid form for people
on the go, rigorously-tested to provide the nutrients the body needs. One
bottle serves as a single meal for anyone with a busy schedule. Last year,
Heaven Labs had a turnover of more than 50 million crowns and is looking to
expand its existing network in Europe and newly to the United States.
