## Definition

EETree (电子森林, "Electronic Forest") is a Suzhou-based hardware education platform offering FPGA learning kits, circuit-simulation tools, and video curricula. Founded in 2019, EETree Information Technology Limited positions itself as a premier talent-development institution for China's electronics industry.

The company entered Western maker discourse on April 14, 2026, when its US holding entity [EETree LLC](https://news.ycombinator.com/item?id=47945522) acquired Tindie — the indie hardware marketplace founded in 2012 and previously owned by Supplyframe and Siemens — triggering a two-week platform outage and a wave of community scrutiny about ownership transparency.

## Analogy

Think of it as the O'Reilly Media of Chinese electronics, now owning the marketplace that makers used to sell their projects.

## Why it's emerging now

On April 14, 2026, Siemens/Supplyframe sold the maker hardware marketplace Tindie to EETree LLC — a Washington State entity linked to Suzhou-based EETree Information Technology. A two-week site blackout, opaque communication, and community questions about the registered address put the company under immediate scrutiny.
