Software Development Arment worked as lead developer and
chief technology officer (CTO) of the
Tumblr microblogging platform and
social networking website from its inception in February 2007 until September 2010, when he left to concentrate fully on
Instapaper, a tool for saving web pages to read later. Arment announced on April 25, 2013, that he had sold the controlling interest in Instapaper to
Betaworks. In July 2013, Marco released Bugshot, an iOS application for marking up screenshots, to help people report software bugs. Marco transferred ownership of Bugshot to Lickability and the app was renamed to Pinpoint in 2015. On September 16, 2015, Arment released Peace, a
Safari content blocker for
iOS 9 using the
Ghostery database. After Peace had held the top spot on the
App Store's list of paid apps for 36 hours, Arment pulled it from the App Store, stating he didn't "feel good" with its resounding success. He elaborated, "While [ad blockers] do benefit a ton of people in major ways, they also hurt some, including many who don't deserve the hit."
Podcasts Between November 2010 and December 2012, Arment hosted a
podcast, Build and Analyze, with
Dan Benjamin on 5by5 Studios. More recently, he has hosted two podcasts:
Neutral and the
Accidental Tech Podcast, with John Siracusa and Casey Liss. He also hosts
Top Four with his wife Tiffany Arment and
Under the Radar with David Smith, both on
Relay FM. In July 2014, Arment released
Overcast, a podcast
application for
iOS. He had been working on the application since fall 2012, and publicly announced it at the
XOXO festival in September 2013. In 2014, Arment also invested $50,000 in
Gimlet Media.
Blogging In December 2006, he launched a blog at Marco.org. As of July 2014, the blog received more than 500,000
page views per month. On January 4, 2015, Arment posted an article to Marco.org about
Apple's declining software quality that unexpectedly went viral. It was picked up by
Business Insider,
The Huffington Post,
CNN,
Heise, and a televised
CNBC discussion segment, among others. ==References==
