AI can build fast. Product judgment decides what deserves to be built.

I am Milan Stancevic, a Senior Product Manager in Munich with 12+ years in B2B and B2B2C SaaS. Product Stance is the label for the products I build and the books I write with AI.

If this works, what changes for the customer or the business?

I test every AI idea with this question. When building gets cheap, the hard part is choosing the problem worth solving, the evidence to trust, and whether a result moved a real outcome.

One stack, each built on the last

Five pieces of work, in the order they happened. Each one used what the previous one taught me.

  1. 1

    Continuous PM OS AI canvas

    My own AI canvas for testing product ideas. It walks an idea through the stages it needs to survive: which problem, for which segment, then the solution.

    Built in Google AI Studio with Gemini.

  2. 2

    Xnumia Agentic payments

    Stress-testing the Xnumia idea in that canvas, plus prototypes in AI Studio, won me the product lead role on the founding team of this agentic payments platform. I then defined the product and its documentation.

  3. 3

    Worth Building Playbook

    A step-by-step playbook for building products with AI: what to hand to AI, and what stays a human responsibility. It grew out of Xnumia and the Product Faculty AI Product Management course.

    Free book. Read it on GitHub.

  4. 4

    PlateMate Prototype

    The prototype before Chef Mealan, built with the Worth Building method. I wrote its eval suite before the product.

    Capstone Honors, AI Product Management Certificate, Product Faculty. Open the prototype, with its evals inside.

  5. 5

    Chef Mealan Live pilot

    A meal planning app for nutrition coaches and their clients. It sizes each meal to the client's calorie and protein targets. Live at chefmealan.com since September 2026 in a closed pilot.

    Built with Claude Code. Evals for the AI parts, automated tests and end-to-end walkthroughs before every release.

How I work

Discovery first

I find the pattern behind requests and turn it into a clear requirement developers can build from, including saying no and explaining why.

Hands-on with AI

I build working prototypes and products with AI coding agents, so a requirement can be tested before it is built properly.

Quality bar before release

AI features get evals with a clear pass mark. Every release passes automated tests and walkthroughs of the main user journeys.
