Cost & supply intelligence
for battery materials & cells.
Wen · wisdom (文) Sura · knowledge (सुर)
Wensura joins proprietary, time-series materials pricing to your techno-economic models — so you can recompute a cell BOM and per-kWh cost the moment cobalt, nickel, or lithium moves, with source attribution your board will accept.
precursor pricing
cell BOM & per-kWh cost
cost-waterfall ready
Your cell cost model is stale
the moment the market moves.
R&D, strategy and procurement teams rebuild cell BOMs and techno-economic models by hand every time cobalt, nickel or lithium moves — to defend capex to the board and arm supplier negotiations.
Weekly Spot Swings
Cobalt, nickel and lithium can move high single digits in a week — and your per-kWh cell cost moves with them.
Capex On The Line
Pre-FID gigafactory decisions hinge on precursor-price sensitivity envelopes that take days to rebuild by hand.
Every Recompute
Re-running a BOM and TEA across price and chemistry scenarios is a slow, error-prone, spreadsheet-bound slog.
A price moves.
Your cell reprices itself.
Wensura joins live materials pricing to your techno-economic model. Pick a market scenario and watch the per-kWh cost stack rebuild — what used to be a spreadsheet afternoon. Preview of the Process & TEA module, currently in build.
Several models answer independently, score each other blind, and one synthesizes the result with source attribution — so qualitative answers don't rest on a single model's guess. Not a literature-search tool.
A data platform, not a chatbot.
Prices × TEA, with a copilot on top.
The moat is a proprietary, structured, time-series materials-pricing corpus joined to your techno-economic models. The multi-model copilot sits on top of that join — it's the interface, not the asset.
- Multi-model cross-checked copilot
- Curated battery knowledge base
- Source-attributed answers
- Time-series precursor & cell pricing
- Structured, queryable, versioned
- The proprietary moat
- AACE Class 3 guided wizard
- Cost waterfall & per-kWh
- Live-pricing recompute
- Patent whitespace mapping
- Competitor cost-curve context
- Filing-risk signals
Market Data — the moat
A proprietary, structured, time-series corpus of battery-materials and precursor pricing. This is the defensible asset: not the papers, not the model — the priced, versioned data that ChatGPT and Elicit can't replicate.
Process & TEA
An AACE Class 3 guided techno-economic wizard. Join live commodity prices to your cell BOM and watch the per-kWh cost waterfall rebuild — the JCAM v7 demo lands at $19.57/kWh anode and $111.46/kWh pack, with mass & energy-balance closure and scenario + sensitivity (tornado).
Battery Base copilot
A multi-model cross-checked research copilot over a curated battery knowledge base. Every answer is independently produced, blind cross-reviewed, and synthesized with source attribution — the trust layer on top of the data, free for academics as lead-gen.
Patent & IP Intelligence
Patent whitespace mapping and competitor cost-curve context, built on the same corpus. On the roadmap as an Enterprise add-on — used internally for freedom-to-operate first, then surfaced once design partners have proven the workflow.
Four pieces, one defensible join.
The proprietary price corpus and the TEA engine are the product. The knowledge base and the multi-model cross-check make the copilot trustworthy on top of them.
A narrow wedge of high-value accounts — not a headcount play.
The buyer is the R&D Director, Head of Materials Strategy, or Procurement & BD lead at an OEM or cell-maker — roughly 280 accounts that buy cost & supply intelligence, not 200K bench scientists.
Built around a working cost model —
not a roadmap.
The numbers below are from the JCAM v7 demo model the platform reproduces today. We're opening a small design-partner cohort to run real cell BOMs before broad release.
Free for academics.
Built for teams that buy.
Self-serve for individuals; a sales conversation for the teams the platform is actually built for. The copilot is lead-gen — the data × TEA join is what teams pay for.
