When one of the co-creators of the popular open-source stream-processing framework Apache Flink launches a new startup, it’s worth paying attention. Stephan Ewen was among the founding team of the open source project back in 2010 and then later became the CTO of Data Artisans, which aimed to monetize Flink. Alibaba then acquired the company in 2019 and rebranded it as Ververica, with Ewen then spending the requisite three years at the company before launching workflows-as-code startup Restate, together with Flink committers and former Data Artisan/Ververica co-workers Igal Shilman and Till Rohrmann.
