About Ruten

We build infrastructure for the devices that restore movement.

Ruten Inc. was founded in Cambridge in 2023 after years of building closed-loop neural interface systems and watching every device project spend months rebuilding the same firmware stack. Signal acquisition, artifact rejection, safety enforcement, stimulation dispatch, written from scratch each time. We built the SDK that keeps not existing.

Founding Story

Why we started Ruten

Rehabilitation device engineering has a recurring bottleneck: the closed-loop signal chain. Every project that integrates electrode acquisition, neural decoding, safety validation, and stimulation dispatch rediscovers the same problems around hardware abstraction, artifact rejection timing, and safety limit enforcement.

The research literature covers the neuroscience well. What it does not cover is the firmware layer that makes those algorithms run reliably on embedded hardware under the constraints of a device that will eventually need regulatory clearance.

Ruten was incorporated in 2023 to build that infrastructure layer as a product, not a per-project rebuild.

Timeline
2023
Ruten Inc. founded
Incorporated in Cambridge, MA. Core team assembled from neural signal processing and embedded firmware backgrounds.
Q3 2023
SDK architecture defined
Four-layer closed-loop architecture specified and initial HAL driver interface designed. First hardware abstraction prototypes built.
2024
Core SDK development
Decode engine, safety monitor, and stimulation dispatch layers built and validated on Cortex-M4 reference hardware. Artifact rejection and safety enforcement modules refined.
Early 2026
Angel funding secured
Angel investment to accelerate SDK completion and early partner device integrations.
2026
Early access program
SDK made available to select device teams and research labs under early access arrangements.
The Team

Who builds Ruten

A small team with deep backgrounds in neural signal processing, embedded firmware, and rehabilitation engineering.

Kazutaka Takahashi
Kazutaka Takahashi
CEO & Co-Founder

Spent a decade building closed-loop signal chains for research-grade neural interfaces, working across embedded firmware and neural signal processing. Founded Ruten to give rehabilitation device teams the middleware infrastructure that kept not existing.

Dr. Nadia Osei
Dr. Nadia Osei
Head of Signal Processing

Built EEG-based motor imagery BCI systems with a focus on spike-sorting pipelines and real-time DSP on embedded hardware. Leads the decoder and artifact-rejection architecture inside the Ruten SDK.

Arjun Mehta
Arjun Mehta
Head of Device Integration

Years writing device drivers and RTOS firmware for multi-channel neurostimulator systems, including USB/SPI/I2C peripheral integration across medical hardware platforms. Owns the hardware abstraction layer and device adapter registry in the SDK.
