What it sells
Online circuit simulator and electronic schematic editor.
Business model breakdown
Buyer: who owns the budget?
UnverifiedIndividual engineers, hobbyists and students/educators purchase memberships themselves (site license for universities is asked about in Q&A).
Trigger: what makes them buy now?
UnverifiedNeed to iterate on a circuit design or analysis before building a prototype, or to learn electronics for a course.
Workflow: what inputs become what output?
Engineers, students and hobbyists draw schematics in the browser, run analog/digital/mixed-mode SPICE-like simulations, and export schematic PDFs, wiring diagrams and plots; circuits can be shared publicly.
Economics: what it saves and how it charges
Paid memberships tiered for Students & Educators, Hobbyists and Engineers (membership page lists these three segments; prices not visible without JS/login).
Distribution: how it reaches customers
Self-serve web app launched with one click, no installation; free interactive textbook, Q&A forum and public example circuits drive acquisition.
