Fractional CTO for Deep Tech: technical leadership for companies that can't afford a full-time CTO

Principal at Nu Kraken

Madrid, Spain

About

A fractional CTO engagement for companies that need senior technical leadership but aren't ready for a full-time hire. Typically 25% or 50% time, three-month initial commitment, extendable.

I build the technical roadmap that aligns with the business goals; de-risk product launches through architecture decisions; lead teams through technical crises with clarity; and help founders and CEOs make better technical decisions, especially the ones that are expensive to reverse.

What makes me different is that I'm Spain-based and I've worked inside American and European deep tech companies, which means I can see the structural problems that are specific to Spanish hardware companies (decision deferral, single-source manufacturing, anchor-client concentration, IP paperwork...)and I can step in and fix them for a while, rather than just diagnose them from a distance.
