About

I’m Claire Cairns, a Web3 communications and PR leader with 15+ years’ experience shaping narratives for emerging technology companies, spanning blockchain/Web3, fintech, and regulated crypto banking, with a growing focus on cybersecurity and post-quantum security as the trust layer powering decentralised systems.

Trusted partner to founders, C-suite and senior stakeholders, delivering strategic communications across product launches, major announcements, executive thought leadership, media relations, ecosystem partnerships, investor narratives and multi-channel content. Since 2021, I have operated as a fractional CMO and PR/communications specialist, embedded across multiple Web3 organisations to lead positioning, communications strategy and execution across EMEA and global markets, often within technically complex, regulation-sensitive and security-focused environments.
