Fractional CTO · AI Advisory

Practical AI transformation for companies that cannot afford to get it wrong

I help mid-market companies navigate AI adoption with the rigour of 35 years in enterprise IT and the perspective of someone who has shipped a production SaaS platform solo.

Three ways I work with clients

Each engagement is shaped around what your company actually needs, not a fixed methodology.

Fractional CTO

Many companies reach a point where technical decisions carry real strategic weight, but the workload does not justify a full-time CTO. I step in as a senior technology partner, typically one to two days a week, working with your leadership on architecture, hiring, vendor selection, and technical direction.

AI Readiness Assessment

Before committing budget to AI, it pays to understand what you are working with. I review your data landscape, existing systems, team skills, and risk tolerance, then deliver a clear report on where AI can genuinely help and where it cannot.

AI Implementation Support

Strategy without execution is just a slide deck. I work alongside your engineering teams to select the right AI tools, build working integrations, deploy Claude Code and MCP workflows, and get AI operating inside your actual business processes.


I have not just advised on this. I have built it.

The hardest thing to find in a fractional CTO is someone who has genuinely built and shipped production software, not just advised on it from the sidelines.

I designed, built, and operate a SaaS platform used by healthcare professionals at the UCSF Center for Mindfulness in Surgery. Every architecture decision, every deployment, every line of code. No team. No co-founders. Just AI tools and three decades of engineering instinct.

Background

Stephan Schoenig

I spent the first three decades of my career in enterprise IT, most recently at Shell, leading infrastructure and digital transformation programmes across multiple continents. I know what it takes to get technology initiatives moving inside large, complex organisations, and I know the common ways they fail.

In 2018 I started building what became BeWell Catalyst, a digital wellbeing platform now used at the UCSF Center for Mindfulness in Surgery. I built and operate it solo, using AI development tools as my engineering team. That experience gives me something most advisors lack: a current, hands-on understanding of what AI can actually do in production, not just in a demo.

I also hold an MSc in Mindfulness-Based Approaches from Bangor University, which informs my work on the Mindful Tech Leader programme and gives me a practical understanding of the human side of technology transformation.

I work with a small number of clients at a time. If the timing and fit are right, I would be glad to hear from you.
