Addepto vs Andersen: pros and cons

Addepto
+ Press recognition from Forbes, Deloitte, and the Financial Times provides independent third-party validation beyond client testimonials.
+ Founder-led AI consulting model since 2018, prior to being acquired.
+ Now backed by KMS Technology's broader resources post-acquisition, which may add delivery capacity.
- Acquired by KMS Technology in December 2025 — leadership continuity, pricing, and delivery-team stability during integration are unconfirmed.
- Reported headcount varies significantly across sources (11–50 vs. 72), making current team size hard to pin down.
- Recent acquisition means the company's standalone track record may not reflect how engagements are run going forward.
Andersen
+ 3,600+ in-house experts across 20 office locations and 16 development centers gives it substantial delivery flexibility.
+ 17 years of company history (since 2007) with a broad, multi-language technology stack beyond AI alone.
+ AI-powered robotic integration line suggests genuine applied AI work beyond pure software consulting.
- AI consulting and ML are a smaller practice within a much broader general software-engineering portfolio (.NET, Java, PHP, Go, mobile).
- Reported HQ city varies between Warsaw and Krakow across sources — confirm the primary contracting entity.
- At 3,600+ employees, clients should confirm they're assigned a genuinely AI-specialized pod, not general developers relabeled for the engagement.
