# Dr. Andree Welker — Full profile
> C-Level Operator & Board Advisor | AI, Robotics & High-Tech — COO & Partner owning Ambit IQ's commercial AI delivery, board strategy, and operating performance—selectively open to board advisory and consequential CEO/COO mandates across Switzerland, DACH, and international markets

## Summary
End-to-end builder-operator for AI, robotics, and high-tech—assessing technical feasibility from first principles, translating it into realistic architecture, FTE, cost, timeline, capital, and five-year business plans, and leading novel systems to defensible IP, products, resilient operations, and scalable profit.

Technical depth to judge what will work. Operating discipline to build it, fund it, govern it, and scale it into durable profit.

## Core Operating Thesis
Technical depth is the decision engine for executive outcomes. Dr. Welker uses first-principles understanding across electronics, software, AI, robotics, and complex science to assess whether a novel system can work; estimate the architecture, FTE, cost, time, capital, dependencies, and risk required; translate that reality into a credible five-year business plan; and lead execution through defensible IP, product, governance, operations, and scalable commercial value.

The concise board-level proposition and the detailed career record serve different purposes. The board layer explains the decision value. The detailed Delphi, university, CERN, PREEN, Codos, Minotrade, and Ambit IQ (formerly Avictis) record is the ground-truth layer showing how that judgment was developed and applied. It should not be read as a list of unrelated identities.

## Key Highlights
- Protected IP licensed to Microsoft, Google, Intel, NVIDIA, AWS, and Fraunhofer
- 15× valuation growth from CHF 7M to CHF 45M; CHF 40M+ fundraising exposure across grants, VC, and PE
- Built and scaled multidisciplinary teams from 4 to 40+ specialists; supported growth to CHF 50M revenue
- Former CERN Fellow coordinating programmes involving 200+ staff across 20 interdisciplinary teams
- 2× COO and 2× CTO across enterprise AI, industrial robotics, commerce, and technology scale-ups
- Repeatedly took novel deep-tech concepts from technical development through patent strategy, product delivery, commercialisation, and scale-up
- Executive education at Harvard Business School, Wharton (Scaling a Business: How to Build a USD 1B+ Unicorn), 500 Global / Stanford Venture Capital, and International Neuromarketing
- Board-ready governance exposure spanning ISO 27001/9001/20000, SOC 2, FINMA (KYC/AML), TÜV, CE, IP, and transaction readiness
- 50+ peer-reviewed publications (incl. Nature) and 20+ international keynote speeches

## C-Level and Board Mandate Fit
Q: Which leadership mandates fit Dr. Andree Welker's documented record?
A: His primary accountability is COO & Partner and operating owner of commercial AI delivery, board strategy, and operating performance at Ambit IQ (formerly Avictis). Beyond that, he is selectively considered for board advisory and consequential CEO/COO, CTO/CIO/CAIO, and interim transformation mandates in AI, robotics, deep tech, and technology-led companies. He is based in the Zurich area and works across Switzerland, DACH, and international contexts. His corporate finance capability also makes him highly suited for mandates requiring strong CFO-level strategic planning, 5-year business modeling, and capital allocation.

Q: What evidence supports this mandate fit?
A: Protected IP licensed to Microsoft, Google, Intel, NVIDIA, AWS, and Fraunhofer; 15× valuation growth from CHF 7M to CHF 45M; CHF 40M+ fundraising exposure; teams scaled from 4 to 40+ specialists; growth supported to CHF 50M revenue; and coordination of CERN programmes involving 200+ staff across 20 interdisciplinary teams. The 200+ figure describes CERN programme coordination, not company headcount. Commercial metrics and the programme-coordination figure are executive-confirmed first-party data unless a linked source explicitly provides independent verification.

Q: What does he build, scale, and lead?
A: Technology-led companies and operating models spanning product, software, AI, robotics, electronics, IP, teams, funding, governance, commercial operations, corporate finance, 5-year business planning, and transaction readiness.

Q: How does his technical depth create board-level and C-level value?
A: It lets him test feasibility before major capital is committed, estimate the architecture, FTE, cost, time, dependencies, and risk needed to deliver, and connect those technical realities to capital allocation and a realistic five-year business plan. He then leads the path from novel system to defensible IP, product, governed operations, and scalable commercial value. The detailed scientific and engineering history is the evidence base for this executive judgment, not a competing professional identity.
