About Marcin Sarnowski

THE PROBLEM WITH AI PROCUREMENT

When enterprises evaluate AI solutions, they face asymmetric information: vendors know exactly what they're selling, but buyers often lack the technical depth to verify claims, assess realistic timelines, or negotiate fair pricing.

That's where I come in.

WHO I AM

I'm Marcin Sarnowski, an independent AI consultant who stands between vendors and clients—always on the client side. I combine unique experience as:

  • AI Engineer & Data Scientist (built 170+ AI solutions in production)
  • AI Consultant & Business Analyst (evaluated dozens of vendor proposals)
  • Business Development Manager (know vendor economics from inside)

This dual perspective—building AI as an engineer AND buying it as a client—gives me insight into both sides of the table. I know all the vendor tricks because I used to be one of them.

WHAT I DO

I provide technical due diligence and independent advisory for companies investing in AI:

Vendor Proposal Review** – Technical and commercial analysis of AI vendor offers, identifying red flags, unrealistic promises, and inflated pricing.

Second Opinion Service** – Independent verification before major AI decisions. Is the proposed solution right for your needs? Are timelines realistic? Is the price fair?

AI Strategy Consulting** – Helping define AI roadmaps, prioritize use cases, and prepare RFPs that attract serious vendors (and filter out the rest).

Implementation Oversight** – Monitoring vendor performance during projects to ensure deliverables match promises.

WHY VENDOR-NEUTRAL MATTERS

I don't build AI solutions anymore—I only advise. No partnerships, no commissions, no conflicts of interest. My only incentive is your success.
