The Problem

The €100k gap in chip design

99% of hardware teams can’t afford professional analog design tools. The market has two extremes and nothing in between.

Free Tier
€0
Manual everything. No AI, no optimization, no modern UI. Hours of hand-tuning for every design iteration.
KiCad · ngspice CLI · Xschem
Schemline fills this gap
€0 – 5k/yr
AI-native design. Modern editor, automated optimization, professional simulation: from free academic licenses to affordable startup plans.
Schematic + Sim + AI + PDK
Enterprise
€100k+/yr
Powerful but prohibitively expensive. 1990s interface. Requires dedicated IT infrastructure and seat licenses.
