The scaling ladder · Stage 02

Sample
Phases (A/B).

A-sample and B-sample campaigns built for program qualification — not a lab demo. The cells you qualify here are the cells you field, produced on the platform that carries them to series.

Qualification is where most cell suppliers quietly swap lines. We do not. What you qualify is what you scale — same platform, same process, no hidden requalification waiting downstream.

What happens here

Qualify on the line that will run your series.

A and B samples exist to answer one question for your program office: can this cell be trusted at scale. We build them on the same modular lines that will later run your rate production, so the answer you get is the answer that holds — not a promising sample from a pilot bench that behaves differently once volume starts.

Every lot ships with traceable process data, so your qualification evidence is defensible and your auditors are answered before they ask.

  • A/B sample lots to your qualification target
  • Same platform as series — no line swap
  • Traceable, auditable process records
  • Engineered to your form factor and envelope
How you move up

No requalification penalty when you move to rate.

Because qualification happens on the production platform, moving to ramp-up is a change of volume, not a change of process. That removes the single most expensive surprise in cell sourcing: passing qualification on one line and then having to re-prove everything on another.

You move up when the A/B samples clear your program’s gates — cleanly, with the data to prove it.
