Martin Kraus - Author and Founder of delavo.de
Over 20 years of experience as a Product Owner, Business Analyst, and IT Consultant go into every review on delavo.de - structured, transparent, and free of marketing fluff.
About Me
I’m Martin Kraus, a freelance Product Owner, Business Analyst, and IT Consultant based in Munich, Germany. For more than 20 years I’ve worked on digital projects for companies - from requirements analysis and prioritization through to successful delivery. I run delavo.de as an independent project, applying the same rigor to AI tool reviews that I bring to my professional work.
My Professional Background
My career sits at the intersection of IT, process design, and product ownership:
- Currently a freelance Product Owner / Analyst focused on digitalization
- Several years as Data Protection Coordinator at an international corporation
- Over 5 years as a Business Analyst at DeutschlandCard / Bertelsmann (CRM, requirements and usability management, BDSG and GDPR projects)
- Further roles as Analyst and Project Manager at Aachener Bausparkasse AG, CORYX Software GmbH, and GSD-Software
- Public sector projects, as well as IT consulting on corporate sustainability (NEOMAA)
- MBA in Insurance Management, Hochschule Coburg
- Degree in Business Information Systems, FH Konstanz
- Certifications: Certified ScrumMaster (CSM), Certified Scrum Product Owner (CSPO), Professional Scrum Master, ITIL v3 Foundation
You can find my full professional background as an IT consultant and Product Owner at martin-kraus.com.
Why I Review AI Tools
As a Product Owner, evaluating software and tools is part of my daily work: assessing value, checking risk, weighing cost against outcome. I apply that same approach to delavo.de’s AI tool reviews. Instead of repeating marketing claims, I assess every tool against fixed, transparent criteria - the same way I do for my clients.
How I Test on delavo.de
Every review on delavo.de follows a fixed, weighted scoring model with up to eight categories, extended with tool-specific bonus criteria. Assessments are based primarily on official manufacturer information and product documentation; pricing and feature claims are verified directly against the provider’s own pages. Reviews are updated regularly whenever features or pricing change. The focus is on the German-speaking market - including language quality, data protection, and GDPR compliance.
Independence and Transparency
delavo.de is funded through affiliate links, which are clearly marked in the text and on buttons (*). These partnerships have no influence on the review criteria themselves: a tool isn’t scored higher because an affiliate program exists. Where I notice discrepancies between manufacturer claims and actual practice, I point them out directly in the relevant review.
Contact and Further Profiles
Questions, feedback, or corrections on any review are always welcome - via the delavo.de contact form or through one of my professional profiles:
