Fractional iOS Lead · European scale-ups

Stop carrying iOS-shaped risk on your own.

I embed into European scale-ups as their iOS lead for the months they actually need one. Stabilizing the team after a senior leaves, running the migration the roadmap keeps pushing, or holding the iOS leadership seat while you hire the permanent lead.

Carrying iOS alone?

Thirty minutes. No deck, no pitch. Just a conversation about what's actually on your plate.

Frequently asked

The questions scale-up CTOs, VPs of Engineering, and Heads of Mobile ask most often. Answered straight.

What is a fractional iOS lead, and how is it different from a senior contractor?

A senior contractor is hired to ship features. A fractional iOS lead is hired to run the iOS function: architecture decisions, technical roadmap, hiring support, the calls a permanent iOS lead would make if you had one. Code still ships, but the unit being bought is leadership, not hours. The shape suits scale-ups that need senior iOS direction for the next three to twelve months without taking on the cost or commitment of a permanent hire.

What does a typical engagement look like?

Three productized shapes. A 12-week stabilization when a senior engineer has just left, focused on keeping the lights on, running hiring, and identifying the next internal lead. A 3–6 month delivery lead for a stalled migration (e.g. SwiftUI, modularization, Tuist, Swift Concurrency). Or an embedded retainer at around three days a week with a 3-month minimum, for teams that have no iOS leadership and won't hire one in the next year. Each is scoped and time-bounded up front.

Do you work alongside an existing CTO and iOS team?

Yes, that's the default. I'm not a CTO replacement or an agency. The engagement reports to the existing CTO or VPE and works with the iOS team that's already in place. A large part of the value is being the connective tissue for the iOS team while a permanent lead is hired, and translating between iOS and the rest of the org along the way.

Who is this not a fit for?

Pre-seed founders evaluating native development for the first time. Enterprise procurement cycles and rate sensitivity. The US market. And any company culture that uses pressure as a management tool.

Do you write code, or just advise?

Both. This engagement is fundamentally about leadership, but leadership only earns its keep by making the product better and trust gets built through hands-on work, not just direction. Expect a mix of decisions, written direction, hands-on implementation in the places that matter most, and the unglamorous work of keeping the team's onboarding doc, ADRs, and release process honest.
