Architecture for AI systems. Backing for tech founders.
YOPITER is the company of Jan Paul Buchwald, an independent software architect and angel investor. I work where business decisions, product direction and engineering reality need to line up — and invest in early-stage technology companies built with the same discipline.

Where decisions cross boundaries
The hardest questions around AI adoption and platform design are rarely purely technical. They involve business priorities, product choices, organisational constraints and engineering reality at the same time.
That intersection is where I work: making trade-offs explicit, turning them into implementable decisions, and staying close enough to engineering to test whether those decisions hold.
