Pavel Durov, 40, and founder of Telegram, kept a secret for 15 years: he donated sperm at clinics in at least 12 countries, without later tracking whom he helped conceive.
Six of his children were born naturally with three different partners. The rest, more than 100, still do not even know that he is their father.
It all started as a favor to a friend who could not get pregnant. Durov continued donating anonymously, year after year, until he lost the exact count of how many children he had helped bring into the world.
Today his fortune is estimated at 17.000 billion dollars, according to Forbes.
In an interview with the French magazine Le Point, he confirmed that he has already drafted a will: all his children, no matter how they were conceived, will have the same rights to his inheritance. But there is one condition that changes the whole picture: no one will be able to claim a single dollar until June 19, 2055, thirty years after the document was signed.
