TestimonialsHear from our users
Kaiber uses Sieve for our production AI video gen workloads. Our end-to-end shipping speed would be notably slower without Sieve, as they handle so many common, yet complex requirements out of the box. In addition, their team is exceptionally communicative and have always worked quickly to address our feedback.
Eric Gao, CTO
Zight uses Sieve to power all our production AI capabilities. Our team loves the fact that Sieve is one roof where all our video AI features can live under. It allows us to move at unparalleled speed from prototype → production.
Phin Hochart, Head of Product
Sieve strikes the right balance between production-ready solutions and a flexible platform to scale our GPU workloads. They also partnered with us to develop solutions and were hyper responsive to our needs.
