Jane Marie’s The Dream

Exploring the world behind MLMs

Little Everywhere, led by Jane Marie (This American Life) and Dann Gallucci (Modest Mouse) strategically launched their new documentary podcast The Dream about the mysterious world of multi-level marketing (MLM) companies.

Grey Horse built a comprehensive public relations strategy that put the podcast on the map, resulting in numerous tier-one placements including features in Vanity Fair, Rolling Stone, BBC America, The Los Angeles Times, and Vox Media. Following the launch, The Dream topped Apple Podcasts’ charts for weeks and was named to Apple’s List of Best Podcasts in 2018 and The Atlantic’s 50 Best Podcasts of 2018. In its first season, the podcast reached 10 million downloads.

Rage Becomes Her

Helping women put their anger to good use

In her first book, award-winning writer and activist Soraya Chemaly encouraged women across the world to harness their anger into positive personal and societal change. Grey Horse supported her messaging by coordinating a successful book launch party at Corkbuzz and creating a detailed social media strategy, as well as a full suite of Rage Becomes Her-branded graphics and audiograms.

The outreach campaign, led by Grey Horse, earned Chemaly fifteen notable publication mentions and/or features in Refinery29, ELLE, and The Washington Post, among others. The book quickly rose to the top of the Amazon charts and helped propel Chemaly’s career. In 2019, Grey Horse prepared Chemaly for her first TEDWomen talk which reached over 2.1 million views online.

The Ocean Agency

Fighting climate change through engagement

This international non-profit combines creativity, technology and powerful partnerships to drive awareness for ocean conservation, but in 2017, they wanted to build impactful content marketing around coral reef conservation which led Grey Horse to create a brand voice, style, and tone for outreach to funders, partners, and the general public.

Grey Horse provided strategic, high-level public relations messaging through a series of ghostwritten blog posts that were published in major outlets such as National Geographic, TIME, and Google. Within a few months, The Ocean Agency amassed thousands of new social media followers, with growth rates reaching well over 50%. Grey Horse’s efforts helped The Ocean Agency and its Netflix feature documentary, Chasing Coral, make the shortlist for an Academy Awards nomination. That same year, the French government appointed The Ocean Agency as the official coordinator of the International Year of the Reef for 2018.

United Nations

Training digital world ambassadors

In 2018, the United Nations lacked consistent messaging on its social media channels. In order to create a streamlined way to standardize its social media posting practices across one hundred channels in eight different languages, Grey Horse led a series of in-house workshops for over twenty United Nations social media specialists. With Grey Horse’s direction, the United Nations developed formalized guidelines and detailed best practices for their respective platforms. Workshop participants reported dramatic boosts in confidence dealing with daily routines, high-pressure situations, and social media messaging. The United Nations now has profiles on all major social media platforms and more than 50 accounts.

MIT Technology Review

Making science tech feel like magic

Recognizing the need to progress in the digital era, this 120-year-old magazine needed new practices in order to expand their readership and attract a younger audience. Grey Horse led a series of workshops and trained staff in engagement techniques and social media tools. We provided strategic guidance on the development of a series of podcasts, videos, and digital communities that allowed MIT Technology Review to reach their intended audiences. As a result of these efforts, the magazine achieved a 3x increase in Twitter engagement rates. MIT Technology Review was also named one of the best scientific content creators by Synthego.

When the magazine hosted their first CES event, they worked with Grey Horse to create a unique, memorable experience for c-suite guests unfamiliar with the brand. Providing an escape from the standard technology-packed CES events, Grey Horse helped MIT Technology Review host a memorable, intimate dinner at a secret location in the desert: Calico Basin, Red Rock Canyon. Fifty hand-curated guests joined the impactful, memorable event and welcomed the only CES event without WiFi.

Al Jazeera English

Speaking out in the Arab Spring

Al Jazeera, the prominent international news network, wanted to step boldly into the digital age, so they created a broadcast outlet for social media. To support Al Jazeera’s mission of giving a ‘voice to the voiceless,’ Grey Horse created The Stream, a daily show and digital community for broadcast news.

The Stream launched on the day Osama bin Laden was killed in Pakistan and featured the first and only interview with the man who witnessed it. This landmark story led to a revolution in online news programming for Al Jazeera English during the Arab Spring, and The Stream was nominated for the 2011 Emmy Award for Breaking News and won Webby People’s Choice Award in 2012 and Royal Television Society’s Most Innovative Programme in 2012 and the Gracie Award for Outstanding News Talk Show in 2013.

With over thirty-six radio shows and podcasts, produced both in-house and by affiliated production companies, New York Public Radio (NYPR) needed a consistent audience development strategy across a multitude of platforms.

Grey Horse trained over one hundred staff members in workshops that covered analytics, audience engagement, KPI measurement, and more. NYPR’s audience increased tenfold over the next two years, and earned them praise for the ability to provide coverage in the midst of Hurricane Sandy which reached millions.

PBS Newshour

Leading a legend into the digital era

With a reputation as one of America’s most trusted broadcast institutions, PBS Newshour needed to transition to incorporate a digital-based identity while safeguarding their journalistic standards and integrity.

Grey Horse built a comprehensive social strategy for engaging new audiences across all platforms, showcasing the client’s strengths as producers of thoughtful, high-quality video content. PBS Newshour’s social channels saw massive month-over-month gains, including growth rates of 15%+ on key social platforms, and ultimately culminating in an Emmy nomination for their livestream of the Deepwater Horizon oil spill in the Gulf of Mexico.

Feminist Fight Club

Proclaiming a manifesto in style

To celebrate the launch of Feminist Fight Club, Jessica Bennett wanted to throw a ‘feminist wedding,’ Grey Horse teamed up with Good Peoples to bring Bennett’s fantasy to life with an exclusive 450-person ‘Support Your Local Girl Gang’ event in Red Hook, Brooklyn. The venue-busting party featured media luminaries from across the world, as well as a variety of feminist vendors and Bennett’s favorite all-female doo-wop band.

Feminist influencers shared their support on social media, which ultimately encouraged thousands to spread the word about Feminist Fight Club. Musical entertainment was provided by PEP, GIPHY photo booths were fueled by Dots the game company, which provided a social-friendly photo experience for attendees, and the majority of donated products were given by female-owned companies from New York and Vermont. The event resulted in hundreds of books sold and event GIFS reaching more than 15 million reviews on GIPHY.
