What our customers say
“0% product downtime. 100% product confidence.”

Vadim Markovtsev
Founding Engineer at poolside
I really appreciate that I’ve never seen any outage in Neptune. And since we’re training an LLM, that it’s super critical to not have any outages in our loss curve.
Other than that, there are things you often take for granted in a product: reliability, flexibility, quality of support. Neptune nails those and gives us the confidence.
Zelda Mariet
VP of Research at Bioptimus
When you train foundation models, you need an experiment tracker. We run experiments that are extremely costly and time-consuming, and we want to extract as much information as possible from all of them. So we need an extremely precise experiment tracker that works under various conditions, online and offline, and allows us to connect experiments in sometimes non-trivial ways. And this is why Bioptimus decided to use Neptune.
