BQ (former name: Mundo Reader) was a Spanish company brand of user electronics devices, such as smartphones, tablets, e-readers and 3D printers among other products.

[4][5][6][7] In 2018, the Vietnamese conglomerate Vingroup acquired 51% share of BQ and active in Vietnam under the name of VinSmart.

[13] By 2020, bq appears no longer to be in the phone market, with all devices removed from the company's web-page.

The English language home-page now presents Robotics, 3D-printing and product development consulting as the focus of the company, at least internationally.

In 2021 their web-page informed visitors that it had ceased business operations and only made available links to software downloads for the 3D-printer Witbox Go and to their educational offerings.
