Stream Announces $38 Million Series B Funding

Today, I’m excited to announce that Stream has closed its $38 million Series B funding round, led by Felicis Ventures’ Aydin Senkut with participation from Series A lead investor GGV Capital and 01 Advisors. This round follows just six months after our $15 million Series A in August, bringing total financing to $53 million.

Stream experienced a 517% increase in revenue from our chat product in 2020, more than doubling our chat and activity feed user base to support more than one billion end users. Over the past year, organizations were forced to move swiftly to expand online operations and facilitate on-screen communication in a world that became almost fully virtual. Many of them turned to Stream’s chat API and SDKs to efficiently implement messaging solutions to keep up with the market uptake of in-app chat as it became the dominant medium for day-to-day communications.

Stream provides APIs that enable product teams to build chat and activity for their applications at scale in a fraction of the time and cost of developing in-house. Stream powers in-app experiences for more than a billion end users, supporting customers in segments like healthcare, education, finance, virtual events, dating, and social. Notable customers include TaskRabbit, NBC Sports, Unilever, Delivery Hero, Gojek, eToro, and Stanford University.

Words from our Investors

Aydin Senkut, founder and managing partner of Felicis Ventures, recognized market potential in Stream's proven chat technology and approached Schellenbach through an introduction by a Felicis founder almost immediately after the close of the company’s Series A. Senkut, an original super angel turned multi-stage investor, is well-known for backing Shopify, Fitbit, Rovio, PluralSight, and API-focused startup Adyen.

“APIs allow project managers to move much more efficiently than in the past, and as a result, we’re seeing continued growth in the sector,” said Senkut. “Stream is at the forefront of the API wave, and we’re very pleased to have them join the Felicis portfolio.”

“We've loved working with Thierry, Tommaso, and the entire team at Stream over the past six months and continue to be impressed by their growth and dedication to elevating in-app messaging and activity feeds for more than a billion end-users globally,” said Tiffany Luck, investor at GGV Capital and Stream board member.

“Stream’s technology addresses a common problem in product development by offering an easy-to-integrate and scalable messaging solution,” said Dick Costolo, co-founder and managing partner of 01 Advisors, and former Twitter CEO. “Beyond that, their team and clear vision set them apart, and we ardently back their mission.”

Additional investors in the round include Olivier Pomel, CEO of Datadog; Tom Preston-Werner, co-founder of GitHub; Amsterdam-based Knight Capital; Johnny Boufarhat, founder and CEO of Hopin; and Selcuk Atli, co-founder, and CEO of Bunch. Knight, Pomel, and Preston-Werner have historically invested in Stream, while Boufarhat and Atli are new investors.
