unrealistsFractional CTO in Europe—based in Berlin
Need a fractional CTO in Europe—or a fractional CTO in Berlin without a six-month executive search? Unrealists GmbH is based in Berlin. We serve venture-backed and bootstrapped startups across the EU (remote-first, selective travel) and work on site with Berlin and German teams when proximity helps. One senior partner for roadmap, architecture, hiring, and accountability—not a permanent full-time executive.
Startup moments we fit
Pre-seed to Series B: first engineering leadership hire, rebuild after MVP, investor due diligence, re-org after rapid growth, or a product bet that cannot wait for a permanent CTO. Engagements typically run three to nine months—long enough to stabilize delivery, not to become permanent overhead.
Europe-wide, from Berlin
We collaborate with distributed EU teams in English by default; German works for workshops and stakeholder meetings. Legal and billing through Unrealists GmbH, Berlin. Whether you searched for a fractional CTO in Europe or interim tech leadership for a cross-border startup, we align engineering with business goals without requiring a full-time C-level hire.
Berlin & Germany on site
For companies in Berlin and Germany, we offer regular on-site time: architecture and code review with your team, hiring loops, vendor decisions, and leadership through local scale-ups in logistics, mobility, fintech, and SaaS. Fundraising pressure, board expectations, and transformation projects are common reasons teams reach out.
Startups in Germany
Wenn ihr als Startup eine erfahrene Head-of-Engineering- oder CTO-Perspektive sucht—ohne sofort eine Vollzeit-Führungskraft einzustellen—unterstützen wir euch bei Tech-Strategie, Teamaufbau und Umsetzung. Kein generisches „Digital“-Beratungspaket, sondern hands-on Leadership aus der Praxis.
Working together
We usually start with a focused workshop, then embed as fractional CTO or interim VP Engineering where needed. See our process and recent projects for how engagements run.
