Today, Twitter announced that it is acquiring Squad and that the team from the screen-sharing social app will be joining Twitter’s ranks. Squad’s co-founders, CEO Esther Crawford and CTO Ethan Sutin, and the rest of the team will be coming aboard inside Twitter’s design, engineering and product departments, Twitter tells us. Crawford specifically notes that she will be leading a product in the conversations space.

What isn’t coming aboard is the actual Squad app, which allowed users to share their screens on mobile or desktop and simultaneously video chat, a feature that aimed to find the friend use case in screen-sharing beyond the enterprise use case of presenting. The app will be shutting down tomorrow, Twitter confirms, an unwelcome surprise for its user base largely made up of teen girls.

Twitter declined to share further terms of the deal.

The app’s functionality seems like a natural fit for the service, though the company did not confirm whether any tech was coming aboard as part of the deal. Twitter hasn’t been keen to keep separate apps functioning outside of the core Twitter app. Vine was infamously shut down, upsetting users who likely later rallied behind TikTok, a massive success story and perhaps one of the biggest missed opportunities for American social media companies. Meanwhile, Periscope which has largely bumbled along over the years, is in a particularly fragile place with app code emerging just today that indicates an impending shutdown for the app.

Squad was notably partnered closely with Snap and was an early adopter of many of the company’s Snap Kit developer tools. Building so much of the app using Snap’s developer tools could have made porting the tech to Twitter’s infrastructure a more complicated task, especially when considering how often Snap Kit apps are tied quite closely to the Snapchat user graph.

Squad raised $7.2 million in venture capital from First Round, Y Combinator, betaworks, Halogen Ventures, ex-TechCrunch editor Alexia Bonatsos’s Dream Machine and a host of other investors. Squad was in the right place at the right time in early 2020. When the pandemic first struck, CEO Esther Crawford told TechCrunch that usage of her app spiked 1,100%.

Crawford spoke at length about the challenges of scaling a modern social app while avoiding the pitfalls of toxicity that so often seem to come with reaching new heights. In an interview with TechCrunch last year, she told us her team was “trying to learn from the best in what they did but get rid of the shit.”

In a Medium post, Crawford also took the opportunity of her startup’s exit to lobby investors to start backing more diverse founders.

“I hope that our exit will tip the scale a bit more toward convincing investors to put money into diverse teams because each success is another proof point that we, the historically under-capitalized and underestimated founders, are a good bet,” Crawford wrote in a Medium post. “Invest in women and people of color because we will make you money.”
