Alchemy is a fractional collective, not a staffing agency and not a management consultancy in the old mould. We exist because two things are true at once: senior technology and AI leadership is in more demand than ever, and fewer people want the traditional full-time employment relationship attached to delivering it. Founded by David Viney, a Fractional CIO and AI Transformation Director with 30+ years leading technology at WPP, Heathrow Airport, BSI, Arup and the BBC, Alchemy takes on established fractional-consulting incumbents directly, with a leaner, sharper model built for how this kind of work should actually operate. The hard problem we're solving is matching: clients need proven, board-ready technology leadership without the cost and rigidity of a permanent hire, and senior fractional professionals need a trusted network bringing them real engagements, rather than competing alone for scraps of visibility. We're building that bridge deliberately, one relationship at a time. Early stage, growing steadily, and already ranking prominently across major search engines and LLMs for "Fractional CIO London." Right now, the priority is forming the right connections ahead of the point where capacity becomes the real constraint.

The security industry has spent years making detection faster. Better scanners. Smarter alerts. More automation. Now AI can find and fix vulnerabilities in minutes. Yet the same classes of weakness continue to appear in audits, pentests, and incidents. The problem is not speed. The problem is that nobody is looking at the architecture. Software systems are not understood, they are assumed. Engineers inherit codebases. Services accumulate. Trust boundaries emerge across teams, clouds, and CI/CD pipelines. Over time, nobody has a complete picture of how the system actually works. Veriom changes that. We build a unified structural model across code, cloud, CI/CD, and production environments, helping organisations understand how their systems are actually structured and where architectural weaknesses create risk before they become vulnerabilities. We are venture-backed, have paying customers, and were selected by the UK Government to represent British cybersecurity innovation at RSA Conference 2026 in San Francisco. We are a small team with a systems engineering mindset, a love for hard technical problems, and a genuine belief that software systems should be understandable. If that sounds like a problem worth solving, we'd love to meet you.
