Flock, a cloud-based team collaboration service, has attracted 25,000 enterprise users and customers including Tim Hortons, Whirlpool and Princeton University. It’s a market that has already drawn interest from global technology giants like Vole, Amazon and Facebook.

Bhavin Turakhia said he wanted to make Flock bigger and better than anything he had built before.

Flock is pitched as a way to share ideas in real time while doing away with communication hierarchies, at a cheaper price than rival services. Its free version integrates tools like a to-do list and a polling app that teams can share with each other while also allowing users to summon an Uber or take part in audio and video conferencing. Popular apps like Trello, Twitter, Mailchimp and Google Drive can be combined with the platform.

Flock has set its sights on disrupting a segment where Slack and Microsoft have staked out claims, Flock’s monthly charges are $3 per user for its premium version while Slack’s per-user charges start from $6.67, according to its website. Both offer a free plan.
