SendBird, a company which helps businesses incorporate messaging into their apps, raised $52 million in a series-B round to scale its business and improve its communication platform.

Its CEO John Kim said the company will use the funding “to attract and retain talented people so we can continue creating the best possible product and scale our go-to-market” while CTO Harry Kim said SendBird will make chat and messaging “as good as in-person communication while creating new ways of communicating that aren’t possible offline.”

“Valued parts of a conversation, such as non-verbal cues, tone, and gesturing, are missing from digital communication,” he added.

The round was led by Iconiq Capital and joined by existing investors, Shasta Ventures; August Capital, Y Combinator, and FundersClub.

SendBird gives businesses tools to add messaging to their app in a way that is in-keeping with their brand, so users stay engaged longer.

Current customers span various industries including gaming, video streaming and healthcare, with its platform used in nearly 12,000 apps.
