BeepStreet is a creative music software developer specializing in synthesizers, samplers, and audio tools for iOS and macOS. The company was founded by Jaroslaw "Giku" Jacek, who handles concept, development, and UI design across the product line. BeepStreet has built a reputation among mobile musicians for technically ambitious DSP work paired with compact, touch-friendly interfaces.

The catalog centers on Drambo, a modular groovebox and audio processing environment with a library of patchable modules, polyphonic stereo signals, multiple sequencer types, and AUv3 hosting. Other notable titles include Sunrizer, a virtual analog synth known for its supersaw emulation and Roland JP-8000-inspired voicing; Zeeon, an analog circuit-modeling synth with a deep modulation matrix; Dagger, an analog modeling synth with multiple classic filter emulations; Impaktor, a physical-modeling percussion instrument driven by tapping surfaces; DerVoco, a vintage vocoder emulation; Combustor, a feedback-based time effect; GyroSynth, a gesture-driven instrument; Otoo, a beatmaker; and RadioUnit, an internet radio app.

The developer is frequently cited in the iOS music-making community alongside names like Moog, Korg Gadget, and AudioKit as one of the go-to sources for serious mobile synthesis, with Drambo in particular treated as a centerpiece app for iPad-based production workflows.
