The problem
Stranding and cabling turn single wires into a conductor or a cable core, and geometry is everything: lay length, lay direction, tightness and roundness decide flexibility, diameter, electrical performance and whether downstream extrusion lands concentric. Fixed bunching, planetary and rigid-strander setpoints cannot hold lay as tension, spool payoff and wire batches vary, so lay drifts, cores go out of round, and birdcaging surfaces reels later as scrap.
What Cablyn does
Cablyn senses payoff tension, take-up, rotational speed and geometry, predicts lay and roundness drift and birdcaging before they form, and closes the loop on strander and take-up speeds and tensions to hold target lay length and geometry, feeding a clean, round, on-spec core to extrusion.
Who it is for
Wire and cable makers running bunching, planetary, rigid and tubular stranding and cabling lines for power, building, automotive and EV harness, data and specialty cable.

Why it needs a GPU
Multi-spool tension and geometry fusion at high rate with sub-250 ms bounded control exceeds CPU real-time budgets. GPU training over stranding telemetry and simulated lay dynamics make predictive geometry control and hit-lay-before-run feasible.
MVP scope and first metric
One stranding line, tension and geometry sensing, lay and roundness prediction advisory then bounded control. First metric: out-of-round or lay-consistency scrap reduction.
Tier. Line tier, $14,000 per stranding line per month, expanding to Plant and Enterprise.
