Klevgrand is a Swedish music software developer based in Stockholm, producing audio effects and virtual instruments for music producers, composers, and sound designers. The company grew out of a shared basement studio on Klevgränd, an alley in Stockholm where its founders originally collaborated on music and film work, and began releasing commercial plug-ins in 2015. The name is a direct reference to that street.

Klevgrand's catalog spans creative effects, utility tools, and sample-based instruments, including the Slammer transient shaper, Brusfri noise reducer, Grainspace granular reverb, Haaze stereo tool, Baervaag FM synth, Tomofon physical-modeling synth, the Stark amp-and-cab suite, the OneShot drum sampler, the Parrot audio repeater, and the Rum-on percussion library. The company is known for distinctive, focused interfaces and for bundling unusual signal-processing ideas into plug-ins aimed at creative workflow rather than pure technical utility.

Alongside its own products, Klevgrand licenses its audio technology to partners in gaming, automotive, and video editing, and has collaborated with hardware and DAW manufacturers on bundled and OEM versions of its plug-ins.

Klevgrand has 50 products cataloged on Equipboard, including Synth Plugins, Reverb Plugins, and Virtual Instrument. Their gear is featured by 3 artists, with the strongest followings in Electronic, Rock, and Folk, World, & Country. Notable users include Bad Snacks, Martin Molin, and Eats Everything. Klevgrand's catalog spans the full price spectrum — from entry-level options to high-end flagships.
