Fractional CPO & CTO services

How I work with you

Embedded

Fractional CPO / CTO

Embedded product and technology leadership, 1–3 days a week. Strategy, discovery, delivery rhythm, hiring and hands-on engineering — plus a successor plan so the role does not stay fractional forever.

· Typical shape: 3–9 months
· For pre-seed to Series B teams

0 → 1

MVP build

From idea to a shippable, validated MVP with a modern LLM and AI stack. Customer validation, scope discipline, and a go-to-market you can actually run after launch.

· Typical shape: 8–16 weeks
· For founders without a product org

Scale & fix

Product turnaround & scale

Stalled product, unclear roadmap, or growth that flattened. I restructure the product operation, re-open PLG/SEO/ASO growth loops and make the platform audit-ready for MedTech or FinTech scrutiny.

· Typical shape: 3–6 months
· For teams of 5–50 people

Full-time

Full-time CPO / CTO

Open to full-time executive product and technology leadership roles for the right mission, team and stage.

· For scale-ups and established companies
· Switzerland-based, hybrid or on-site

FAQ

Frequently asked questions

What does a fractional CPO / CTO engagement look like?

Typically 1–3 days a week for 3–9 months, embedded in your team. I own product strategy, discovery and delivery, and stay hands-on in the codebase and the AI stack. You get an operating rhythm, a roadmap your team believes in, and a successor plan so the role does not stay fractional forever.

Are you available, and where do you work from?

Based in Switzerland, working on-site in CH and remotely across Europe, Asia/Singapore and the UK. I take on a small number of parallel engagements, so start dates depend on current load — use the contact form and I will reply with real availability.

What is your expertise in 0-to-1 product building?

I have built and launched over 10 products from scratch — cloud, SaaS, web and mobile — using a modern LLM and AI stack from MVP to scale. I scaled products to 1M MAU through organic growth (PLG, SEO, ASO) and led cross-functional teams of 15+ FTEs as both CPO and CTO.

What is your experience with AI and LLMs?

Hands-on with Anthropic, OpenAI, Mistral and Cursor. I build agentic systems including a rolling-context mental health chatbot and AI-powered clinical data analysis with intervention suggestions, and I work with locally hosted models such as Qwen 3.6, DeepSeek-R1 (Distilled), Mistral Small 3 and Moonshot AI Kimi K3.

Can you work in regulated environments like MedTech and FinTech?

Yes. CE Medical Device (cat. 2a, MDR) certification for healthcare platforms, FinSA/FIDLEG compliance for FinTech wealth management, Swiss Data Protection (nFADP), GDPR, EU AI Act readiness, Swiss Made Software certification and ISO 9001 certification leadership.

What is the Mental Health Score (MHS)?

A composite wellness metric scaled 0–1000 that integrates PHQ-9, GAD-7, WSAS and other validated clinical assessments with ecological momentary assessment (EMA) daily mood data. I invented it; it is published on ResearchGate and patent-pending.
