Build faster without breaking.

A fractional CTO provides part-time engineering leadership, strategy, architecture, hiring, and team management, without the cost of a full-time executive. You get senior experience applied to the problems that matter most, on a schedule that fits your budget.

Engagements run on a flat monthly retainer, not an hourly meter. Pick Advisor (€300/mo, async-first strategic anchor, one strategic call a month plus async support) or Builder (from €2,000/mo, embedded delivery partner, in three flat tiers). You're buying a predictable monthly outcome, not a timesheet.

Advisor is for teams that have their own developers and want a senior strategic anchor, one strategic call per month plus async support, with 50% off every productized service. Builder is for teams that need delivery, an embedded partner shipping a steady stream of product work, in three flat monthly tiers (Core €2,000, Plus €4,000, Max €6,000), with productized services like Code Review and the Scalable MVP Sprint absorbed into the retainer instead of charged separately.

Start at Builder Core (€2,000/mo). Most teams move one tier up to Plus (€4,000/mo) after the first month, once we both see the real pace. You can resize between tiers month to month with no penalty. If you mostly need strategic guidance rather than hands-on delivery, the Advisor plan (€300/mo) is the better fit.

Each tier is sized for a typical month at that level, so light and heavy months even out. The flat fee buys availability and a predictable budget, not a metered ledger. If you consistently need more than your tier delivers, we move you up a tier; a single busy month is simply absorbed.

I build with an AI agent stack, Claude Opus 4.7 orchestrating a Sonnet worker swarm, that I've refined for over a year. That leverage means each retainer ships far more than a single senior engineer could at the same price. You're paying for shipped outcomes and speed, not for hours on a clock.

One flat monthly fee, billed up front for the month, that's the whole invoice. At the end of each month you get a transparent summary of everything shipped, so you can see exactly what the retainer delivered. No timesheets, no line-item hourly charges, no surprise overages.

I focus on mobile-first companies (Android in particular), SaaS, and startups with an established app or platform. Industries I find most interesting: extreme sports, motorsports, music, and high-end fashion, but I evaluate all opportunities on merit.

We start with a free 15-minute discovery call. If there's a fit, I do a paid technical audit to understand your codebase, team, and goals. From there you pick a plan on the Advisor or Builder intake page and we begin. Advisor has a 3-month upfront minimum; Builder is month-to-month with two weeks notice.

A full-time CTO costs $200–400K/year in salary plus equity (US market data; EU rates run ~70–80% of these figures). A fractional engagement gives you the same calibre of leadership for a fraction of the cost, with no hiring risk. It's the right choice when you need senior guidance but aren't ready to justify a full-time hire.

Both. I'm hands-on by default, I review PRs, write production code, and pair with your developers. Pure strategy without execution is rarely useful. The Advisor plan leans strategic; the Builder plan leans delivery. Both include some of each.
