The Future of Trust: Co-founder Xin Yan on Sign’s Journey and On-Chain Attestation

Welcome back. I am Coco. BlockchainAsia has been rebranded as World Ledger.

I am excited to share this new podcast episode featuring Xin Yan, co-founder of Sign. We discuss his journey from training as an electrical engineer to co-founding Sign, an omni-chain attestation protocol.

We explore Sign’s product offerings, clients, and revenue model — yes, we talk about how to make money! Xin also shares his vision for Sign and the industry and the company’s fundraising experience, and offers advice for fellow founders.

Founded in 2021, Sign is already profitable! Tim Draper wrote a blank check for the pre-seed round, and Sequoia’s U.S., China, and India entities all participated in its Seed Round. Most recently, Binance’s venture arm led Sign’s $16M Series A round. Notably, Sign does not have a token.

Enjoy our conversation and discover why such prominent investors readily invested in Sign.
