Careers at Poseidon

Data is the biggest bottleneck in the next wave of AI development. Poseidon is the full-stack data layer that bridges supply and demand for specialized and IP-cleared training data.

Our Story

Poseidon was born to tackle the hidden bottleneck in AI: access to rare, high-quality, IP-safe data.

Not the 99 percent that can be scraped or generated, but the 1 percent of long-tail, edge-case, multi-modal datasets that truly improve performance.

Our decentralized data layer and DePIN app make it possible for AI companies to source exactly what they need at scale, safely and efficiently.

Backed by a16z, we are building the infrastructure that will power the next generation of AI.

At Poseidon, the work we do shapes AI, our industry, and ourselves. Join us to build systems that matter.
