Ko ia te kaiwhakaara me te Tumuaki o mua o te papaaho rangitaki poto a Tumblr. I tiimata tana mahi, me te kore i whiwhi tohu kura tuarua, hei kaimahi i raro i a Fred Seibert i te kamupene whakairoiro a Frederator Studios, i hangaia ai e ia te papaaho rangitaki tuatahi a te whare wananga me te whakaaro, tuhi, me te whakatika i ta raatau whatunga ataata ipurangi tuatahi, Channel Frederator. I haere a Karp ki te mahi mo te huinga matua ipurangi UrbanBaby kia hokona ra ano ki CNET i te 2006. I tiimata e Karp tana ake kamupene raupaparorohiko raupaparorohiko, Davidville, i mahi tahi ai ia me te kaipūkaha rorohiko a Marco Arment mo nga kaupapa mo nga kaihoko. I te wa o te waahi i waenga i nga kirimana i te 2006, ka tiimata te mahi a te tokorua i runga i te paetukutuku microblogging, i whakarewahia hei Tumblr i te Hui-tanguru 2007. I te 1 o Noema 2017, neke atu i te 375.4 miriona nga tuhinga a Tumblr. I te marama o Akuhata 2009, i whakaingoatia a Karp hei Kaihoko Hangarau Rangatahi Pai rawa atu i te tau 2009 e BusinessWeek ana i te tau 2010, i whakaingoatia ia ki te MIT Technology Review TR35 hei tetahi o nga kaihanga 35 pai rawa atu i te ao i raro i te 35 tau.I te Mei 20, 2013, i panuitia ko Yahoo! me Tumblr kua tae ki tetahi kirimana mo Yahoo! ki te hoko i a Tumblr mo te $ 1.1 piriona. Ko Karp tonu te Tumuaki o te kamupene. I kii a Karp i te Noema 2017 ka wehe ia i Tumblr i te mutunga o te tau.  Pātai: āhea i whakarewahia ai a Tumblr?
