Sixty-Nine Iterations

Originally written: 05 January 2026

Designing for the failure cascade happens in the fine adjustments somewhere between open and shut.

We are currently on our sixty-ninth prototype. That number does not represent progress in a neat, straight line; instead, it represents thousands of small, granular decisions made in direct response to failure rather than success. Each version exists simply because something else before it didn’t hold—a load path twisted under pressure, a joint transferred force poorly, an unexpected failure mode caught us off guard, or a sudden user movement revealed an underlying instability. Iteration isn’t about abstract, theoretical improvement. It is about systematically and ruthlessly removing fragility. This means each new prototype isn’t a celebratory step forward, but a deliberate, protective step away from a known harm.

That is fundamentally how Evan designs. He refuses to build from best-case scenarios, choosing instead to engineer from the absolute worst ones. He consciously avoids clean, idealized performance metrics to look closely at failure cascades, refusing to focus on how systems behave when everything goes right, but obsessing over how they hold when everything goes completely wrong. In the end, sixty-nine isn’t a shiny marketing milestone for us to boast about. It is a quiet, deeply tangible record of listening to the material world.
