Company profile
researched Aug 2026Smack is a Boston-based consumer social media startup that developed a succession of communication products for teenage and young-adult users. Its first product, SmackHigh, was a network of Twitter accounts launched in late 2013 that published anonymous, moderator-reviewed messages submitted by high school students about their schools and rival schools, functioning as a lighter-touch alternative to anonymous messaging apps such as Yik Yak and Secret. Moderation was performed by more than 7,000 student volunteers across 26 states, which the company credited with keeping content free of bullying, harassment and racism.
The company subsequently moved from Twitter-based distribution into native apps, releasing a SmackHigh app, the Smack Chat group messaging app (November 2015) and Smack Live, a live video broadcasting app (October 2016). Its breakout product was Fam, an iPhone group video chat app supporting up to 16 simultaneous participants, positioned by press coverage as the "group FaceTime" feature Apple had not shipped as of its June 2017 WWDC presentation. Fam registered more than 4.3 million users in its first seven months and was referenced, along with competitor Houseparty, in a Facebook survey to teenagers about group video chat.
Founding story
Smack originated in late 2013 with SmackHigh, a series of Twitter accounts started by Giuseppe Stuto that posted anonymous submissions from high school students about their schools and rival schools after moderator review. Stuto later built the company with co-founders Frank Iudiciani and Kevin Flynn, aiming to move the community engaged by the Twitter accounts onto standalone apps. The founders' observation that individual tweets sparked side conversations among friends, combined with the difficulty of retaining users through Twitter accounts alone, drove the shift into app development.
Business model
Smack builds free-to-download consumer mobile applications aimed at teenagers and young users, growing distribution through viral social sharing and, earlier, through large moderated Twitter followings. Its assets were audience-based: Twitter accounts with over a million followers and apps with rapid user registration, supported by venture capital rather than a stated paid-subscription or advertising product.
Traction
SmackHigh's Twitter accounts reached 1.1 million users by late 2015. Fam registered over 4.3 million users in its first seven months, with earlier products showing intense but short-lived engagement: Smack Chat users spent hours in the first 24 to 48 hours before losing interest, and Smack Live users engaged for extended sessions without the app achieving mass adoption.
Latest developments
In June 2017, coverage highlighted Fam's growth to more than 4.3 million users in seven months and noted that the growth spurt had strained the company until investors supplied additional capital. Facebook had referenced Fam and rival Houseparty in a survey sent to teenagers about group video chat.

Market position
Smack was described as a notable social media company in Boston, a market with comparatively few social media firms relative to the West Coast, alongside examples such as Jobcase. In group video chat, Fam competed with Houseparty and with Apple's own FaceTime, which lacked group calling at the time.
SmackHigh's volunteer moderation network of more than 7,000 students across 26 states kept submitted content limited to light gossip and banter, in contrast to anonymous messaging apps such as Yik Yak and Secret that were affected by bullying, harassment and racism and later shut down. Fam offered multi-person video chat of up to 16 participants on iPhone at a time when Apple's FaceTime did not support group calls, a gap highlighted after Apple's June 2017 WWDC presentation.
Technology
Consumer iOS mobile applications spanning anonymous message publishing, group text chat, live video broadcasting with guest hosting, and multi-party video chat supporting up to 16 participants, combined with human moderation workflows for user-submitted content.
Go-to-market
Distribution relied on organic and viral growth: an audience first assembled through SmackHigh's Twitter accounts, then app releases on Apple's App Store where, amid stores holding millions of apps, the company sought viral effects to reach critical mass. Fam's visibility was amplified by press and social media attention to the absence of group video chat in Apple's FaceTime.
Teenagers and young consumers, initially U.S. high school students who submitted and followed anonymous school gossip, and later friend groups using mobile group chat and video chat.
Geography
Headquartered in Boston, Massachusetts, with SmackHigh's volunteer moderator base drawn from high school students across 26 U.S. states.
History
Smack began in late 2013 as a set of Twitter accounts under the SmackHigh brand, where high school students submitted anonymous messages about their own and rival schools for moderator review and posting. The accounts grew to 1.1 million users by late 2015, helping the company raise a $1.65 (million, as reported) seed round while participating in Techstars Boston. The team then moved into app development: an app version of the SmackHigh experience was short-lived, a group chat app called Smack Chat launched in November 2015 without gaining critical mass, and Smack Live, a live-video broadcasting app, followed in October 2016 with high engagement but limited virality. Observing that Smack Live users treated it as multi-person FaceTime, the company pivoted within a couple of months to Fam, its fourth product and first hit, reached after more than three years of iteration. A period of rapid Fam growth strained the company financially before investors provided additional capital.
