Jack Dorsey is een Amerikaanse zakenman die vooral bekend staat als de oprichter van de sociale netwerksite Twitter.

Korte inhoud

Jack Dorsey, geboren op 19 november 1976 in St. Louis, Missouri, raakte als student betrokken bij webontwikkeling en richtte in 2006 de sociale netwerksite Twitter op. Sinds die tijd is Dorsey CEO, voorzitter van de raad van bestuur, en uitvoerend voorzitter van Twitter. Hij lanceerde ook het succesvolle online betalingsplatform Square in 2010.

Vroege leven

Uitvinder van Twitter Jack Dorsey werd geboren op 19 november 1976 in St. Louis, Missouri. Opgroeiend in St. Louis raakte Dorsey op jonge leeftijd geïnteresseerd in computers en communicatie en begon hij te programmeren terwijl hij nog studeerde aan bisschop DuBourg High School . Hij was gefascineerd door de technologische uitdaging van het coördineren van taxichauffeurs, bestelauto's en andere wagenparken die constant in realtime met elkaar moesten communiceren. Toen hij 15 was, schreef Dorsey verzendsoftware die nog steeds door sommige taxibedrijven wordt gebruikt.

Creatie van Twitter

Na een korte periode bij de Missouri University of Science and Technology, ging Dorsey over naar de New York University. In de traditie van informatica-ondernemers zoals Bill Gates, Steve Jobs en Mark Zuckerberg stopte hij met studeren voordat hij zijn diploma behaalde. In plaats daarvan verhuisde Dorsey naar Oakland, Californië, en startte in 2000 een bedrijf dat zijn dispatch-software via het web aanbood. Kort na het opstarten van zijn bedrijf kwam Dorsey op het idee voor een site die het brede bereik van verzendsoftware zou combineren met het gemak van instant messaging.

Dorsey benaderde een inmiddels ter ziele gegane Silicon Valley-bedrijf genaamd Odeo om het concept te pitchen. "Hij kwam naar ons met dit idee: 'Wat als u uw status heel gemakkelijk met al uw vrienden zou kunnen delen, zodat zij weten wat u bent'opnieuw bezig?'"zei Biz Stone, een voormalige Odeo-directeur. Dorsey, Stone en Odeo mede-oprichter Evan Williams startte een nieuw bedrijf, genaamd Obvious, dat later evolueerde naar Twitter. Binnen twee weken had Dorsey een eenvoudige site gebouwd waar gebruikers direct konden posten berichten van 140 tekens of minder, in Twitter-taal bekend als 'tweets'.

Op 21 maart 2006 heeft Jack Dorsey de wereld gepost's eerste tweet: "gewoon mijn twttr instellen." Dorsey werd het bedrijf genoemd's chief executive officer. Hij verwijderde zijn neusring in een poging om naar het deel van een volwassen bestuurder uit Silicon Valley te kijken, hoewel hij zijn jongensachtige, dweilachtige kapsel en abstracte, onderarmlengte tatoeage hield waarvan de vorm onder andere het menselijke sleutelbeen vertegenwoordigde. Mede-oprichter Evan Williams verving Dorsey als Twitter's CEO in oktober 2008, met Dorsey als bedrijfsvoorzitter.

Twitter-succes

Twitter werd aanvankelijk door sommigen bespot als een hulpmiddel voor de oppervlakkige en egocentrische om de details van hun leven naar het universum uit te zenden. Komedie met late comedy Conan O'Brien had zelfs een segment genaamd "Twitter Tracker" dat gebruikers van de dienst bespotte. In de begindagen had de site ook te maken met frequente servicestoringen. Maar toen beroemdheden en CEO's begonnen te tweeten, was Twitter niet langer de dupe van zoveel grappen. Plotseling het hoofd van de "microblogging" -beweging, werd Twitter een krachtig platform voor Amerikaanse presidentskandidaten Barack Obama en John McCain in 2008, als een methode voor het bijwerken van hun supporters tijdens het campagnetraject.

Twitter sprong over naar internationale bekendheid na de presidentsverkiezingen van juni 2009 in Iran, toen duizenden oppositieleden de straat op gingen om te protesteren tegen de geclaimde overwinning van de gevestigde Mahmoud Ahmadinejad. Toen de overheid sms-berichten en satellietfeeds van berichtgeving in het buitenland blokkeerde, overspoelden Iraanse Twitter-gebruikers de site met live updates. Een functionaris van het Amerikaanse ministerie van Buitenlandse Zaken stuurde Dorsey zelfs een e-mail om Twitter te vragen het geplande onderhoud uit te stellen zodat demonstranten konden blijven tweeten. "Het lijkt erop dat Twitter een belangrijke rol speelt op een cruciaal moment in Iran. Kun je het volhouden?" zei een woordvoerder van het ministerie van Buitenlandse Zaken die de oproep beschreef. Twitter heeft voldaan.

Voorbij Twitter

In 2010 had Twitter meer dan 105 miljoen gebruikers die samen zo'n 55 miljoen keer per dag tweeten. Dorsey had zijn zinnen echter op andere projecten gericht. Hij werd een investeerder in het sociale netwerkbedrijf Foursquare en lanceerde een nieuwe onderneming, Square, waarmee mensen creditcardbetalingen kunnen ontvangen via een klein apparaat dat op hun mobiele telefoon of computer is aangesloten. Twitter heeft misschien al een revolutie teweeggebracht in de manier waarop mensen communiceren, maar Dorsey is dat niet'nog niet klaar. "In termen van technologie, wij'we gaan een betere en meer directe ervaring zien rond de dagelijkse dingen die we in het leven doen, "zei Dorsey.

Miljardair zakenman

In november 2013 zag Dorsey zijn persoonlijk fortuin enorm groeien dankzij Twitter'eerste openbare aanbieding. Het bedrijf's aandeel had een startkoers van $ 26, maar de prijs steeg snel tot $ 45 tijdens de eerste handelsdag. Binnen enkele uren is de waarde van Dorsey's ongeveer 23,4 miljoen aandelen maakten hem miljardair. Hij begon al in 2014 de mogelijkheid van een IPO voor zijn andere bedrijf, Square, te bespreken.

In 2015 keerde Dorsey terug naar Twitter. Hij diende eerst als interim CEO en werd vervolgens CEO. Niet lang daarna nam hij officieel het bedrijf over'Op de eerste plaats kondigde hij aan dat het bedrijf ongeveer 8% van zijn personeelsbestand zou verminderen. Deze stap maakt deel uit van een algemeen plan om zich binnen het bedrijf te organiseren's topproductprioriteiten en efficiëntie in het hele bedrijf, & # x201D; volgens een effectendossier door Twitter gemeld in de Los Angeles Times.

Tourists fined and banned from Venice for swimming in canal <a href=https://trip-scan.co>trip scan</a> A couple from the United Kingdom had to cut their vacation in Venice short after being caught swimming in the Grand Canal. The 35-year-old British man and his 25-year-old Romanian girlfriend were forced to return to their home in the UK on Thursday, the same day they arrived in the city, after gondoliers reported them to local police for taking a dip in the canal. The pair were fined €450 ($529) each and expelled from Venice for 48 hours, marking the 1,136th such sanction to be handed down to badly behaved tourists in the city so far this year, according to the Venice City Police. The unnamed couple took the plunge near the Accademia bridge near St. Mark’s Square and gondoliers at the Rio San Vidal kiosk immediately called authorities, who removed them from the water. “I thank the gondoliers for their cooperation and timely reporting,” said Venice Security Councillor Elisabetta Pesce in a statement published by city authorities on Friday. https://trip-scan.co tripscan top “Venice must be defended from those who disrespect it: protecting the city means ensuring decorum for residents and visitors who experience it with civility.” Swimming in the Venice canals is prohibited for a variety of reasons, including the intense boat traffic and the cleanliness — or lack thereof — of the water, according to the city’s tourism ministry. Of the 1,136 orders of expulsion from the city so far this year, about 10 were for swimming.

In July 2024, an Australian man was fined and expelled for diving off the Rialto Bridge after his friends posted about it on social media.
