Helium16

Helium16 powers AI products and services with high-quality human data at scale,covering RLHF, multimodal annotation, for all domains. Put simply, it is about managing your IT, from help desk to infrastructure, as an outside partner.

Who is it for? Mostly small and mid-sized companies. They also list Artificial Intelligence (AI), Generative AI, IT Infrastructure, IT Management and Machine Learning, so expect those to show up in the feature set. As a very small company team themselves (1 to 10 people), they tend to serve customers of a similar scale best. You will probably talk to the people who build it, which is great until you need 24/7 support.

Helium16 is based in Newark, Delaware and founded in 2025. Their site is helium16.com.

Before you commit, look at response SLAs, onboarding, and what is billed per hour. Ask for a trial on your own data, not a canned demo.

If you have worked with Helium16, tell the next buyer what you paid and what surprised you. That is the part of this page we cannot write.
