## About Jan Mensch

Jan Mensch embeds into European scale-up iOS teams as their fractional lead for the months they actually need one. Not a senior contractor, not a fractional CTO, not an agency. The unit being sold is leadership: architecture decisions, technical roadmap, team coordination, hiring support, strategic technical calls. Code is delivered as part of that work, not in place of it.

His moats are deliberate and reinforcing: longevity (iOS since 2009, freelance since 2015), premium-brand trust (Audi, Porsche, Canyon, Red Bull, all kept the work for long engagements), regulated-environment experience (DAK, German statutory health insurance), the interface role between iOS and the rest of the org (CTO, PM, UX/UI, backend, Android), and a European anchor (DACH/EU, bilingual EN/DE where the engagement calls for it).

The promise is **predictability and continuity**. Not velocity, not transformation. Mobile stops being the line in the board deck the CTO dreads.

## Frequently asked questions

**What is a fractional iOS lead, and how is it different from a senior contractor?**
A fractional iOS lead runs the iOS function inside a scale-up for a defined period, making architecture, hiring, and roadmap calls, while a contractor is hired to write features. The deliverable is leadership, not hours.

**What does a typical engagement look like?**
Three shapes: a 12-week stabilization after a senior leaves, a 3–6 month migration lead (SwiftUI, modularization, Concurrency, architecture change), or an embedded retainer at ~3 days/week with a 3-month minimum. Each is scoped and time-bounded up front. If it's unclear which shape fits, the entry product is a two-week iOS function audit (€7.5k fixed, fully credited against an engagement that starts within 60 days): a written report with findings, ranked risks, and a sequenced 6-month plan, plus a 90-minute readout.

**Do you work alongside an existing CTO and iOS team?**
Yes, by default. This is not a CTO replacement and not an agency. The engagement reports into the existing CTO or VPE and is designed to make the iOS team more durable. Including identifying and growing the next internal lead.

**Who is this not a fit for?**
Pre-seed founders, enterprise procurement, the US market, and any culture that uses pressure as a management tool. Refusing those engagements protects the brand more than any case study can build it.

**Do you write code, or just advise?**
Both. The unit sold is leadership, but hands-on technical work. Architecture decisions implemented in real code, tricky reviews, surgical fixes on release night. Everything is part of it.
