Direct Competitive Threats — ranked

Where the fight actually is: WiS is not fighting LFP in the 2–4 h utility slot, nor Form Energy at 100 h multi-day storage. The battleground is 4–24 h daily-cycling storage where fire-safety, cycle life and non-China supply decide the deal. The companies below compete for that same slot — ranked by how dangerous they are to WiS.

Positioning Map — duration × chemistry lane

Bubble size = cumulative funding. The shaded band is the 4–24h daily-cycling slot — crowded with sodium-ion and organic-flow players, but in the zinc lane WiS is the only membrane-free Zn–MnO₂ architecture (Eos = bromide, UEP/Vanadis = sealed cells, e-Zinc = zinc-metal at 24h+). ● WiS · ● critical threat · ● high · ● medium / reference

The LDES Graveyard — why capital discipline matters

Six funded competitors left the field in 24 months. The common failure mode was not chemistry — it was factory capex before bankable cell data. WiS stays capital-light until the chemistry is bankable.
