Maisha ya mwanzo na kazi
haririKoum alizaliwa Kiev, Ukraine. Ana asili ya Kiyahudi.[2] Alikulia Fastiv, nje ya Kiev, na baadaye akahamia Mountain View, California na mama na bibi yake mwaka 1992,[3] ambapo walipata msaada wa kijamii kwa kupewa nyumba ya vyumba viwili,[4] akiwa na miaka 16. Baba yake alikuwa amepanga kuwafuata Marekani lakini alibaki Ukraine,[5] na kufariki mwaka 1997.[4] Koum na mama yake waliendelea kuwa na mawasiliano naye hadi alipofariki.[6] Mwanzoni mama yake alifanya kazi ya uyaya wakati yeye alikuwa anafanya kazi ya usafi dukani. Mama yake alifariki mwaka 2000 baada ya kuugua ugonjwa wa kansa.
Alipokuwa na umri wa miaka 18 Koum alianza kuwa na shauku ya kujua masuala ya kuprogramu kompyuta. Alijiunga na chuo kikuu cha San Jose State University na wakati huo huo akifanya kazi Ernst & Young.[4]
Mwaka 1997, Koum alikutana na Brian Acton, mwanzilishi mwenza wa WhatsApp, wakati akifanya kazi Ernst & Young.[4]
Yahoo!
haririMwaka 1997, Koum aliajiriwa na Yahoo! kama mhandisi. Aliacha shule muda mfupi baada ya hapo.[4] Kwa miaka tisa baadaye Koum and Acton walifanya kazi pamoja katika kampuni hiyo. Septemba 2007 waliacha kazi Yahoo! na kutembelea nchi kadhaa za Amerika ya Kusini na kucheza mchezo wa ultimate frisbee. Wote waliomba kazi katika kampuni ya Facebook lakini maombi yao yalikataliwa.[4]
WhatsApp na Facebook
haririJanuari 2009, Koum alinunua iPhone na hapo akatambua kuwa kampuni ya Apple ilikuwa ina mpango wa kutoa app mbalimbali. Alimtembelea rafiki yake Alex Fishman, huku wakinywa chai, walizungumza kwa masaa kadhaa juu ya wazo jipya alilokuwa nalo Koum.[4] Koum alichagua jina la WhatsApp kwasababu ilitamkika kama "what's up", na wiki moja baadaye wakati wa siku yake ya kuzaliwa, February 24, 2009, alisajili WhatsApp Inc. huko California.[4]
WhatsApp haikuwa maarufu hapo mwanzoni. Baadaye ilianza kupata watumiaji wengi na hapo akamshawishi rafiki yake Acton, ambaye alikuwa bado hajapata kazi, kujiunga na kampuni. Koum alimpa Acton hadhi ya mwanzilishi mwenza baada ya Acton kuipa kampuni dola za Kimarekani 250,000.[4]
Februari 9, 2014 Mark Zuckerberg alimwomba Koum kujiunga na bodi ya Facebook. Siku 10 baadaye Facebook ilitangaza kuinunua WhatsApp.[7][8][9][10][11]
Mnamo Aprili 30, 2018, Koum alitangaza kuondoka kampuni ya WhatsApp na pia bodi ya wakurugenzi wa Facebook kutokana na mgogoro na Facebook[12] It was originally thought that by leaving he was forfeiting his unvested stock, worth almost $1 billion.[13]
