a16z CSX-backed Cambrian raises $6 million seed to build blockchain data oracle network

Cambrian, a startup building blockchain data infrastructure for institutions and AI agents, has raised $6 million in a seed funding round.

Franklin Templeton and Polychain Capital co-led the round, with participation from Flow Traders, Selini Capital, Paper Ventures, Nomad Capital, and others, Cambrian said Wednesday. Angel investors, including Jason Mo, Avi Felman, and TrueNorth co-founders Alex Lee and Willy Chuang, also joined the round.

Cambrian began fundraising toward the end of last year and formally closed the round last month, founder and CEO Sam Green told The Block. The round was structured as a simple agreement for future equity (SAFE) with token warrants, Green said, declining to disclose valuation. Franklin Templeton and Polychain took board observer seats as part of the round, Green said.

The seed round brings Cambrian's total funding to date to $11.9 million, including a previous $5.9 million pre-seed round led by a16z Crypto Startup Accelerator (CSX) last year.
