Hello, I'm Felix.
I build AI, CRM and data systems for marketing and sales.
Analysis, concept, implementation and operations in one pair of hands. You talk directly to the person who also builds your system, at a quality your IT can review and take over.
SERVICES
Three disciplines, one chain: data as the foundation, CRM as the engine, AI as the accelerator. I deliver all three layers myself, from concept to running system, vendor-neutral and free of reseller ties.
Agentic AI for marketing and sales
Agentic systems that do real work: I design, implement and operate AI agents and multi-step workflows for marketing and sales, plus AI brains as central context layers over your company knowledge. On top, review and advisory for planned agentic setups before anything gets built.
CRM and marketing automation
From evaluation through implementation to operations: customer lifecycle marketing that measurably converts, team trainings that teach best practices and state of the art and make your team more efficient, and MarTech operating models for real-time, trigger-based marketing.
Data foundations
The foundation underneath: connecting data sources, building data warehouses, cleaning, migrating and transforming data, and shipping ML models as data products right where marketing uses them.
Systems I build again and again: running in my own companies and at clients every day. Three examples.
AI setups that empower your team
AI for marketing and sales teams that empowers instead of replaces: full knowledge and full context on brand guidelines, company tone of voice and customer history, for everyone, with more personalized customer interactions and noticeably more speed. Better campaigns, better customer communication, and thanks to a context layer no knowledge is lost when someone leaves the company.
Generate campaigns in one click
Copy, images and every element that belongs to a campaign are created in one workflow. Best practice here is human-in-the-loop: your team collaborates with the agent, for example via Slack, reviews the quality, and generates high-quality output fast in a multi-step process, within defined guardrails such as your brand guidelines and in a data protection compliant way. From idea to finished campaign, without bottlenecks in copy or design.
Sales that never forgets
Your sales team is always perfectly prepared, forgets nothing and never misses a deadline: key stakeholder research, a complete picture of every customer, personalized outreach down to the individual contact. Find, win and nurture better leads without anything slipping through.
WORK
Three examples from recent work, one per discipline.
Dynamic website elements in hours instead of weeks
An agentic flow that turns a plain-language Slack message into an on-brand, technically valid website element: conversion elements, banners and overlays, built on the existing template library and brand guidelines. Once explicitly approved, the agent automatically opens a pull request for the development team. Marketing tests new variants in hours while code review and deployment stay with engineering.
- Scope
- Project, approx. 2 months, from platform evaluation to handover
- Collaboration
- Together with the development and marketing teams of the company
+96% to +233% conversion in experiments
Customer lifecycle marketing as a continuous experimentation program: define segments, design experiences per segment, orchestrate consistently across all channels, test hypotheses, evaluate statistically, iterate. Individual experiments achieved significant conversion uplifts between +96% and +233%; a winback experiment lifted conversion by +117% and revenue by +103%.
- Scope
- Retainer since 2019, ongoing
- Collaboration
- Together with the CRM team of the company
Data warehouse, daily ETL, free reporting
Evaluated solutions, then built: Azure Synapse as the warehouse, an ETL pipeline in Azure Functions that syncs, cleans and lands the data daily, connected to Power BI. Every report has carried up-to-date booking data ever since.
- Scope
- Project, approx. 14 months
- Collaboration
- Delivered independently
CONTACT
Let's talk about your project.
If what you see here resonates and you want to run a project that fits my topics, or you need an expert for them: just tell me about your idea.
In that conversation I'll tell you straight away how I would build it, and share my experience with you. Afterwards, take your time to decide whether we work together or you build it yourself. No strings attached.
It starts with getting to know each other: a video call about your initiative or, ideally, a meal together. I am based in Zurich and happy to travel anywhere in German-speaking Switzerland, whether Zug, Lucerne, Basel or Bern. I want to understand who I am dealing with and what your team is planning, so I can support you in the best possible way.
I enjoy the exchange and always love hearing about interesting projects. Just reach out, I'll reply within one business day with a proposed time to talk.
