AllSides's Overview

Total employees36
HeadquartersMill Valley
Founded2011

AllSides, Inc. is a media technology company that exposes people to information and ideas from all sides of the political spectrum so they can better understand the world — and each other. Known for its patented media bias ratings, AllSides curates news from Left, Center, and Right sources, helping users identify bias and think for themselves. As a Public Benefit Corporation, AllSides aims to strengthen democratic discourse by freeing people from filter bubbles and promoting balanced news consumption.

Where is AllSides's Headquarters?

HQ Function

Serves as the administrative and coordination hub for editorial operations, technological development, marketing, and strategic partnerships. It guides the company's mission to provide balanced news and media bias ratings.

Notable Features:

As AllSides operates with a largely distributed team, its 'headquarters' functions more as an administrative center rather than a traditional large physical office. The focus is on robust digital infrastructure and collaborative online tools.

Work Culture:

AllSides fosters a mission-driven, collaborative, and intellectually engaging work culture. Emphasis is placed on open dialogue, embracing diverse perspectives, and maintaining journalistic integrity. The distributed nature of the team promotes autonomy, strong communication, and flexibility.

HQ Significance:

The Mill Valley postal address places AllSides within the influential San Francisco Bay Area, a hub for technology and media innovation. However, its primary significance lies in its digital platform and its national impact on media literacy and political discourse, rather than a specific physical edifice.

Values Reflected in HQ: The operational model reflects values of agility, lean operations, a focus on mission impact over physical overhead, and leveraging technology to connect a distributed workforce dedicated to media transparency.

Location:

While AllSides is incorporated in the USA, its digital platform, news aggregation, and media bias ratings are accessible to a global audience online. Its mission to provide balanced news and foster understanding across divides resonates internationally, particularly in regions where media polarization is a concern. The team itself is distributed, potentially including members working from various global locations, contributing to its worldwide perspective and reach.
