Haris Rehman / AI Product, Solutions & Venture Builder
For teams hiring an AI product, solutions or forward-deployed lead, here's how I think and what I ship.
Five case studies below. Each one: the business problem, the AI-enabled workflow, the prototype I built, the tools, and the commercial angle.
Based in Berlin, remote-first. Fifteen years building ventures, now shipping AI-enabled workflows in days, not quarters.

Stated as assumptions, with the inputs shown.
