Tenstorrent is a Canadian semiconductor company founded in 2016 that designs artificial intelligence accelerators and RISC-V processors, and it is unusual in the field for licensing its designs as intellectual property as well as selling hardware. It is led by Jim Keller, the chip architect behind AMD's Zen and Apple's early mobile processors, and its argument against Nvidia is openness: an open instruction set, open source software stack and licensable designs rather than a closed platform. Headquartered in Toronto and backed by investors including Samsung, Hyundai and Bezos Expeditions, it competes in a market where software maturity matters as much as silicon.

Voodoo is a French mobile gaming and consumer applications company founded in 2013 that built its business on hyper-casual games, titles simple enough to understand in seconds and monetised almost entirely through advertising rather than purchases. As advertising costs rose it moved deliberately into hybrid-casual and subscription applications, acquiring the social network BeReal in 2024 and building a portfolio of utility and dating apps alongside the games. Headquartered in Paris and backed by Tencent and Goldman Sachs, it reports billions of downloads and is one of the largest mobile publishers in the world by install volume.
