Independent CTO & executive advisory

Technology
decisions
you can defend.

Decide what to fund, what to stop, and how to deliver. Tie technology spending to revenue, operating cost and the business’s ability to grow.

I’m Christian Prokopp. My background spans CTO and CDO roles, leadership of an international consulting practice and hands-on engineering. I work with CEOs and leadership teams to connect the business decision with what the organisation can build and operate.

Delivery & AI adoption

Find out why delivery is falling short.

03 / Technical work behind the advice

Close enough
to test the advice.

I continue to build so that my advice is informed by the costs, constraints and review work behind today’s tools.

I built the Semaverse.ai research platform, connecting agents, source data and working documents, and helped Camunda develop early AI prototypes that informed its product and technology direction.

Tax Shrink, Llamar and Turmberg are independent projects in development, not client case studies. Each needs human review before wider use.
