Skeleton Technologies Tech Stack

Supercapacitor manufacturer for grid, defense, and data center power resilience

Appliances, Electrical, and Electronics Manufacturing Tallinn, Harjumaa 201–500 employees Founded 2009 Privately Held

Skeleton Technologies manufactures supercapacitors—energy storage devices that handle power surges, backup, and peak shaving in mission-critical systems. The company is scaling aggressively: 57 open roles with 31 posted in the last 30 days, dominated by senior engineers (28 positions) and manufacturing roles (10), plus a new Head of Finance and Head of People hire. Active projects signal capital and operational expansion: major financing rounds, new factory integration, and ultracapacitor deployment into data center UPS systems. The pain-point list (factory scale-up, throughput, defects, EHS compliance, capital raising) reflects a hardware manufacturer moving from proof-of-concept to high-volume production.
