Stream Raises USD 15M Series A to Accelerate Growth Across In-App Messaging, Activity Feeds, Inc., the creator of enterprise-grade activity feed and chat APIs, announced the close of its USD 15 million Series A financing, led by GGV Capital with participation from new investor 01 Advisors, Knight, seed round lead investor Arthur Ventures, and other backers, including Olivier Pomel, CEO of Datadog, and Tom Preston-Werner, co-founder of GitHub, the company said.

Tiffany Luck from GGV Capital will join the Stream board of directors. Stream plans to invest heavily in scaling its global team across engineering, sales, and marketing.

Stream provides APIs which enable product teams to build chat and activity feeds for their applications at scale in a fraction of the time and cost of developing in-house. It allows product teams to focus their vital development resources on what makes their app unique. Stream powers experiences for over a billion users across their two products and is on a mission to elevate the quality of apps for users worldwide.

During these difficult times, Stream is helping companies in segments such as healthcare, education, finance, fitness, dating and social to connect their community. The APIs are designed for scalability and several of the largest websites and apps use Stream. Notable companies include Healthline, Powerschool, Stocktwits, Freeletics, Match, TaskRabbit, Imgur and Dubsmash.

Historically, companies have built feeds and chat in-house. With applications growing faster than ever before, and users expecting a seamless UX, building in-house is becoming less feasible. Stream offers a level of performance and quality that companies used to spend years on with an internal team. Much like we saw immense capacity improvements with the shift from traditional data centers to the cloud, Stream enables organizations to move to a higher abstraction level when building apps.

Stream was founded by Thierry Schellenbach and Tommaso Barbugli in Amsterdam, The Netherlands. The company participated in the Techstars NYC program. After the program, Stream moved its headquarters to Boulder, Colorado. Today it employs 55 people in Amsterdam and Boulder, as well as remote.
