Quantum hardware has advanced faster than the pool of people able to program it. A Berlin startup has raised $2.2M to widen that pool.
RhymeQ emerged from stealth with a pre-seed led by Ground State Ventures, with Vanagon Ventures, Plug and Play and Freiraum Ventures participating. Daniel Volz, Tamás Varga and Christina Wu founded the company in 2026.
Python in, quantum circuits out
Its platform, Rhyme, adds an abstraction layer so developers with ordinary Python skills can write code, with compilers translating it for quantum hardware. Multiple processor backends are supported, which reduces lock-in to a single vendor, and it works with Nvidia’s CUDA-Q for GPU-accelerated simulation.
The pitch rests on a practical bottleneck: circuits today are typically debugged by physicists with doctorates, which caps the number of teams that can ship quantum software at all. Rhyme targets debugging as much as authoring, aiming at production-grade work rather than experiments.
Volz came to the problem after implementing quantum computing at BASF and building quantum products at Kipu Quantum, and argues the vibe-coding shift that reshaped classical development has no equivalent yet on quantum stacks.
The money funds engineering hires, the enterprise platform and developer community work, plus integrations with hardware vendors’ software libraries.
