Countable Corporation (known simply as Countable) is a left-leaning software company that provides social engagement tools to businesses to provide them with social engagement tools, including tools to contact elected officials or conduct get-out-the-vote campaigns.
The firm was founded in 2013 by Bart Myers and Peter Arzhintar and later acquired Causes, a consumer-facing community engagement and activism platform founded by Sean Parker. Countable has worked to implement left-of-center “social impact” programs at companies including Levi Strauss, Uber, Patagonia, and the New York Times. The firm also was a vendor for the 2016 Bernie Sanders presidential campaign and provided technology hosting services for the virtual 2020 Democratic National Convention. Countable also hosts the website for CEOs for Gun Safety, a gun-control advocacy project formed by the CEO of Levi Strauss and Co. and advocacy group Everytown for Gun Safety.   
Countable was founded in 2013 by Bart Myers and Peter Arzhintar, cofounders of SideReel, a web-based television company that they sold to TiVo in 2011. Myers had been involved with the 2004 presidential campaign of former Vermont Gov. Howard Dean (D) and sought to start a new company focused on politics, particularly around campaign finance reform and online privacy legislation. Dean’s 2004 campaign manager, Joe Trippi, has been an advisor for the company since its inception. 
The first iteration of Countable was an application that summarized bills before Congress and allowed users to immediately email their congressional representatives to support or oppose bills. The software was initially only available as an application linked to Facebook. 
In 2019, Countable acquired Causes and Brigade, both applications founded by Facebook co-founder Sean Parker that included a ballot guides and other voting and engagement tools. Brigade was the parent company of Causes and its sale to Countable was attributed to a lack of success in user adoption.
