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.

Splitsense is building an AI agent that does conversion optimization the way a senior CRO specialist would, end to end and continuously. The problem we're solving is one every founder and growth team knows. You have analytics, heatmaps, session recordings and dashboards, but none of them tell you what to actually do. Turning that data into insight takes hours of digging. Turning insight into an experiment takes developer time most teams don't have. So most websites never get optimized at all, and the ones that do run a handful of tests a year instead of a steady stream. That's a hard problem because good CRO isn't one skill, it's a pipeline of them: reading funnels and spotting where users drop off, forming hypotheses worth testing, writing copy that converts, building variants without breaking the site, running the statistics honestly, and knowing what to test next. We're encoding that entire pipeline into autonomous agents. Splitsense crawls your site, learns your brand and audience, analyzes real visitor behavior through its own analytics and session replay, finds the leaks, then writes, launches and measures A/B tests on its own. Multi-armed bandits shift traffic to winners while tests run, so learning turns into revenue faster. The result: the kind of continuous experimentation program that used to require a CRO consultant, a copywriter, an analyst and an engineer, now available to a solo founder for the price of a SaaS subscription. We're a small, senior, fully remote team that ships fast and uses our own product on our own funnel every day. If you want your work to compound, everything we learn makes the agent smarter for every customer.
