What Liminal does
Liminal Insights, Inc., founded in 2015 (originally as Feasible) and headquartered in Emeryville, California, is a battery manufacturing intelligence company that deploys ultrasound inspection combined with proprietary machine learning analytics for lithium-ion battery cell quality control. The company's flagship EchoStat platform comprises three product lines: EchoStat ARRAY (high-speed in-line inspection of pouch and prismatic cells at six seconds per cell with 100% coverage), EchoStat RASTER (high-resolution at-line analysis in under 15 minutes), and EchoStat THETA (off-line/at-line inspection for cylindrical cells). EchoStat Analytics layers physics-assisted ML models on the raw acoustic data to deliver electrolyte saturation monitoring, defect detection (separator folds, electrode misalignments, tab weld defects, lithium plating, foreign particles), and capacity fade prediction with reported 83-98% accuracy.
Liminal sells and installs EchoStat hardware systems directly into customer battery manufacturing facilities, with deployment models spanning off-line, at-line, and in-line configurations. The company serves two primary customer segments: large-scale battery cell manufacturers (including gigafactory operators such as Northvolt) and automotive OEMs requiring supplier quality validation. Customers include Northvolt, an unnamed major Asian battery cell manufacturer, an unnamed major US automotive OEM, and a Tier-1 Li-metal cell manufacturer. Pricing is not publicly disclosed and operates on a custom enterprise sales basis. Strategic channel partnerships with Waygate Technologies (Baker Hughes) and Schneider Electric/AVEVA extend market reach and integrate inspection data into broader manufacturing execution systems.
The company has raised over $35M cumulatively across private venture rounds (Series A2 of $17.5M led by ArcTern Ventures, Northvolt, and Ecosystem Integrity Fund in February 2023; $10M strategic round led by LG Technology Ventures in October 2024; $8.5M Series A led by Noro-Moseley Partners in April 2025) plus government grants from ARPA-E ($1.8M), NSF, and the California Energy Commission ($2.75M). Liminal's geographic footprint spans the US, Europe, and Asia, with headquarters at 1175 Park Ave, Emeryville, CA. The company operates with 11-50 employees and is led by CEO/CTO and co-founder Shaurjo Biswas, with a board including representatives from UTEC, ArcTern Ventures, and Chrysalix Ventures, plus advisors from LG Energy Solution and Applied Materials.

Liminal product offering
Product offeringCore offering
Liminal sells the EchoStat platform, an ultrasound and machine learning inspection system that performs non-destructive quality control on lithium-ion battery cells during manufacturing. The platform inspects 100% of cells in production lines in approximately 6 seconds per cell, delivering electrolyte saturation analysis, defect detection, and capacity fade prediction for prismatic, pouch, and cylindrical cell formats.
Product overview
Liminal offers the EchoStat platform, a battery manufacturing intelligence system combining ultrasound inspection with machine learning analytics. The platform consists of three product lines: EchoStat ARRAY (high-speed in-line inspection for prismatic and pouch cells), EchoStat RASTER (high-resolution at-line analysis for detailed defect diagnosis), and EchoStat THETA (cylindrical cell inspection). EchoStat Analytics provides the AI layer with custom trained models for electrolyte saturation analysis, cell performance prediction, defect detection, and uniformity analysis. The platform is designed for cell and process development, factory ramp-up, and high-volume manufacturing.
